UNITED STATES DISTRICT COURT
SOUTHERN DISTRICT OF NEW YORK
────────────────────────────────────
UNITED STATES OF AMERICA,

                      Plaintiff,              24-cv-7214 (JGK)

           - against -                        MEMORANDUM OPINION AND
                                              ORDER
VISA, INC.,

                     Defendant.
 ────────────────────────────────────
JOHN G. KOELTL, District Judge:

     In the not-too-distant past, consumers and merchants

transacted primarily using cash. In the 1960s, ATM cards

proliferated, enabling cash access at the point of sale. In

around 1990, debit cards eliminated the need for cash altogether

by enabling consumers to pay for purchases by drawing directly

on their bank accounts. More recently, financial technology

(“fintech”) firms began offering alternatives to debit cards

such as PayPal and Cash App Pay.

     For decades through today, Visa, Inc. has operated the

largest debit network in the United States. This case is about

whether, in seeking to increase and protect its debit card

network, Visa violated the federal antitrust laws.

     The Government brought this action alleging that Visa

monopolized and attempted to monopolize the United States market

for general purpose debit network services, in violation of

Sherman Act § 2, 15 U.S.C. § 2, by using contracts with banks


                                   1
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 2 of 58



and merchants that restrained trade unreasonably, as well as

unlawful agreements not to compete with competitors and

potential competitors. The Government also alleges that Visa

entered into both types of contracts in violation of Sherman Act

§ 1, 15 U.S.C. § 1. The crux of the complaint is that Visa used

de facto exclusive dealing contracts to prevent Visa’s rivals in

debit from ever having the opportunity to compete effectively,

and fashioned customized incentive contracts to stymie market

entry by fintech firms.

     Visa moved to dismiss the Government’s complaint on three

grounds. First, Visa argues that the Government’s alleged

product market is implausible because it excludes other payment

networks that, like debit networks, move money between bank

accounts. Second, Visa argues that the complaint fails to allege

anticompetitive conduct and thus harm to competition because the

complaint does not allege that Visa discounted prices for Visa

debit to below its costs. Third, Visa contends that the terms of

its current contracts disprove and defeat the allegation that

Visa agreed with competitors and potential competitors not to

compete.

     Because Visa requests the premature resolution of factual

issues at the pleadings stage, and for the additional reasons

explained below, Visa’s motion to dismiss is denied.

                         I. Factual Background

     Unless otherwise noted, the following facts are taken from

the complaint (“Compl.”), ECF No. 1, and are accepted as true

for purposes of the present motion to dismiss.1

                         A. Debit Transactions

     Debit transactions draw funds immediately and directly from

the consumer’s bank account. Compl. ¶¶ 24, 26. Tens of millions

of Americans prefer to transact or must transact using debit.

Id. ¶¶ 1, 27, 28. A debit transaction involves several actors,

including the consumer, the merchant, and their respective

banks. Id. ¶ 2. In the debit industry, the consumer’s bank is

called the “issuer” and the merchant’s bank is called the

“acquirer.” Id. ¶ 4.2 Debit networks are the intermediaries that

facilitate debit transactions. Id. ¶¶ 3–4, 29.

     When a consumer pays using debit, the merchant selects a

debit network for the transaction and requests payment through

its acquirer. Id. ¶¶ 4, 35. The acquirer then sends the

consumer’s information to the debit network. Id. ¶ 35. Using

that information, the debit network asks the issuer for

authorization. Id. If the consumer has sufficient funds and


1 Unless otherwise noted, this Memorandum Opinion and Order omits all
internal alterations, citations, footnotes, and quotation marks in
quoted text.
2 Issuers and acquirers may work with processors that connect banks

with debit networks. Id. ¶ 30 nn. 1–2. Unless otherwise specified,
issuers and issuer processors are referred to together, and acquirers
and acquirer processors are also referred to together. Id.

                                    3
    Case 1:24-cv-07214-JGK    Document 89   Filed 06/23/25   Page 4 of 58



there are no indications of fraud, the issuer places a hold on

the funds and sends an authorization over the debit network to

the acquirer. Id. At this step, the issuer also deducts an

“interchange fee,” paid by the acquirer to the issuer for the

issuer’s services. Id. At the last step, the acquirer sends the

authorization to the merchant, who completes the transaction.

Id. These steps typically transpire in seconds. See id. ¶ 36.

                             B. Debit Networks

     To facilitate transactions, debit networks provide

consumers with a unique credential that is ready for use at all

merchants participating in the network. Id. ¶ 31. Behind the

scenes, debit networks facilitate the transfer of funds by

providing “rails”—the means through which banks communicate and

transfer funds. Id. Debit networks allegedly also provide

payment guarantees for merchants, dispute and chargeback

capabilities for consumers and issuers, and fraud protections

for all parties. Id.

     Banks, not debit networks, ultimately move money from

consumers to merchants. Id. ¶ 32. But debit networks clear and

oversee the interbank settlement process. Id. Each day, debit

networks aggregate all transactions for each bank, net out

applicable fees, and provide banks with daily settlement

reports, which banks then use to transfer funds among

themselves. Id.

                                     4
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 5 of 58



     A debit network can process a transaction only where the

debit network connects to both the issuer and the acquirer and

is accepted by the merchant for the particular transaction. Id.

¶¶ 4, 30, 54. A debit network’s desirability and effectiveness

therefore depend on the breadth of the network’s acceptance and

enablement by all participants. Id. ¶ 55. Put another way, debit

networks operate in a two-sided market with strong indirect

network effects. See ¶¶ 5, 55, 154; see also Ohio v. American

Express Co., 585 U.S. 529, 535 (2018) (“Indirect network effects

exist where the value of the two-sided platform to one group of

participants depends on how many members of a different group

participate.”). Indirect network effects benefit incumbent debit

networks with widespread enablement by issuers and acceptance by

merchants; for smaller debit networks, lack of scale presents a

significant barrier to entry. Id. ¶¶ 170–71.

     Debit networks generally charge (1) per-transaction network

fees to both issuers and acquirers; and (2) fixed network fees

to acquirers. Id. ¶¶ 22, 43. List prices for network fees are

called “rack rates.” Id. ¶ 12. Acquirers pass on at least some

network fees to merchants. See id. ¶ 45.

     In using debit, acquirers (and thus merchants) incur

additional expense because acquirers pay interchange fees to

issuers for issuers’ services. Id. ¶¶ 44–45. For the largest

issuers with $10 billion or more in assets (“regulated

                                   5
    Case 1:24-cv-07214-JGK    Document 89   Filed 06/23/25   Page 6 of 58



issuers”), the Federal Reserve has capped the interchange fee

amount. See id. ¶¶ 44, 52; Corner Post, Inc. v. Bd. of Governors

of Fed. Reserve Sys., 603 U.S. 799, 805 (2024). For smaller,

unregulated issuers, “[t]he amount of the fee is set by the

payment networks, like Visa and Mastercard.” Corner Post, 603

U.S. at 805; Compl. ¶ 44.

                             C. Forms of Debit

     In the United States, the most common form of debit is the

general purpose debit card. See id. ¶ 30. Other forms of debit

include alternative rails developed by fintech firms. Id. ¶ 60.

                              1. Debit Cards

     Debit cards are issued by issuers that have contracted with

debit networks. Id. ¶ 30. When issuing debit cards, issuers

select one “front of card” network and place that network’s

graphic on the front of the card. Id. ¶¶ 4, 34, 38–39. The

issuer also chooses which “back of card” networks to enable and

may graphically identify those networks on the back of the card.

Id. Debit card credentials include a sixteen-digit card number

and other security features like the expiration date, card

verification value, security chip, and four-digit

personal-identification number (“PIN”). Id. ¶ 34.

     The following figure illustrates the typical features and

graphic design of a debit card:



                                     6
     Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 7 of 58




Id. ¶ 34 Fig. 1.

     Four front of card networks operate in the United States:

Visa, Mastercard, American Express (“Amex”), and Discover. Id.

¶¶ 40, 53.3 Visa is the front of card brand for over 70% of

debit-card payment volume in the United States. Id. ¶¶ 53, 67.

Mastercard comes in at second with around 25%. Id. Amex and

Discover comprise the remaining share. Id. In part due to

significant switching costs, issuers enter into long-term

contracts with either Visa or Mastercard for front of card

placement and rarely change their front of card network. Id.

¶¶ 40, 172.

     On the back of the card, issuers have more networks to

choose from. See id. ¶ 41. Visa and Mastercard each operate an

affiliated back of card network: respectively, Interlink and

Maestro. Id. Other back of card networks include STAR, NYCE, and

Discover’s Pulse. Id. ¶¶ 41, 107. Visa and Mastercard debit

cards include Interlink and Maestro, respectively, as well as at

least one unaffiliated back of card network. Id. ¶ 41.

     Back of card networks are often called “PIN networks”

because they require PIN entry for transactions where the

consumer taps or swipes their card. See id. ¶¶ 41, 56. But PIN

networks also offer “PINless” technology, which can process

debit transactions without PIN entry. Id. ¶ 56.

     PINless technology is not automatically available; the

issuer must enable it for particular types of transactions. See

id. ¶ 42. Issuers may also decide not to enable PIN networks to

process certain types of transactions, such as transactions over

a set dollar amount or transactions with weak encryption. See

id. ¶ 58. In contrast, Visa and Mastercard are accepted by

nearly all United States merchants that accept debit; put

otherwise, merchant demand for Visa and Mastercard debit is

inelastic. Id. ¶¶ 170–71.



                                   8
    Case 1:24-cv-07214-JGK    Document 89   Filed 06/23/25   Page 9 of 58



     Consumers can use debit cards for purchases at brick-and-

mortar stores for “card-present” (“CP”) transactions and online

for “card-not-present” (“CNP”) transactions. Id. ¶¶ 1, 28.

Today, CNP debit transactions comprise about half of all debit

spending. Id. ¶ 37. That number represents a dramatic increase

since 2010 and is still growing. Id.

     For CNP transactions, debit card credentials are either

entered manually or pulled from a digital wallet. Id. As a

result, PIN entry almost never occurs online. Id. Instead, other

features like multifactor authentication help secure CNP

transactions. Id. Accordingly, if the issuer does not enable

PINless transactions, PIN networks are unable to process CNP

transactions. See id. ¶¶ 42, 56, 58.

                             2. Fintech Debit

     “Fintech debit” refers to alternative debit rails developed

by fintech firms. Id. ¶ 60. Like debit card networks, fintech

debit networks require both consumer and merchant enrollment and

participation. Id. ¶ 117. But fintech debit networks rely

directly on the consumer’s bank account number, rather than a

debit card credential, and store the consumer’s bank account

number on the network for future use. Id. ¶¶ 61, 108, 113. In

that way, fintech debit networks can cut debit card networks out

of the transaction. Id. ¶ 108.



                                    9
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 10 of 58



     In processing a transaction, fintech debit networks

communicate with the issuer to authorize and clear the

transaction, and then provide settlement services by initiating

a payment to the acquirer. Id. ¶ 61. At the final step, fintech

debit networks transfer funds using services provided by

“interbank payment networks.” See id. In addition, fintech debit

networks also provide dispute resolution and chargeback

capabilities for consumers and issuers, payment guarantees for

merchants, and fraud protections for all parties. Id. ¶ 113.

     Fintech debit networks can be embedded in different payment

solutions, such as digital wallets. Id. ¶¶ 109, 116. Two types

of digital wallets exist. Id. ¶ 116. “Staged digital wallets”

like PayPal and Cash App enable consumers to pay with preloaded

funds or funds pulled from a linked bank account, either

directly or using a debit card credential. Id. “Pass-through

digital wallets” like Apple Pay and Google Pay transmit payment

credentials (such as a debit card number) directly to a

merchant’s acquirer. Id. The acquirer then uses the

passed-through credential to process the payment. Id.

                    D. Interbank Payment Networks

     Interbank payment networks, like debit networks, transfer

funds between bank accounts. See id. ¶¶ 61, 159. In that sense,

interbank payment networks are lower-cost alternatives to Visa’s

debit offering. Id. ¶ 61.

                                   10
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 11 of 58



     Three examples are Automated Clearing House (“ACH”), Real

Time Payment (“RTP”), and FedNow. Id. ¶¶ 61, 115. Offered by The

Clearing House or the Federal Reserve system, ACH has been used

for decades to facilitate interbank settlement and for recurring

fixed payments like disbursements and paychecks. See id. ¶¶ 115,

159. More recently, The Clearing House launched RTP and the

Federal Reserve launched FedNow. Id. ¶ 115. Both RTP and FedNow

are real-time interbank payment networks that facilitate

instantaneous transfers. Id.

     Unlike debit networks, however, interbank payment networks

do not provide dispute resolution and chargeback capabilities

for consumers and issuers, payment guarantees for merchants, and

fraud protections for all parties. Id. ¶¶ 152–53, 159. Moreover,

ACH requires the consumer to enter and verify bank account and

routing information at each merchant. Id. ¶ 159. For merchants,

ACH is allegedly more subject to fraud than debit card

transactions. Id. In addition, ACH can take several days to

settle payment and even longer to make funds available. Id.

¶¶ 115, 159.

                       II. Factual Allegations

     The Government’s allegations against Visa are summarized

below.




                                   11
    Case 1:24-cv-07214-JGK    Document 89   Filed 06/23/25   Page 12 of 58



                             A. Recent History

     Until the early 2000s, Visa and Mastercard enjoyed

exclusive relationships with their respective issuers for both

credit cards and debit cards. Id. ¶¶ 48–49. In 2003, those

exclusivity agreements were held to be unlawful. United States

v. Visa U.S.A., Inc., 344 F.3d 229, 241 (2d Cir. 2003). Related

private litigation settled shortly thereafter. Compl. ¶ 49.

Pursuant to that settlement, Visa and Mastercard each agreed to

provide merchants with the ability to accept the respective

brand’s debit cards without accepting the brand’s credit cards,

and vice versa. Id. Between 2006 and 2008, the landscape shifted

further as Visa and Mastercard both became independent public

corporations. Id. ¶ 50.4

     Most banks continued to issue only Visa or Mastercard debit

cards. Id. Other networks rarely outcompeted Visa and Mastercard

for front of card placement because of Visa and Mastercard’s

unmatched scale of existing merchant relationships. Id. And

switching costs prevented Visa or Mastercard from easily

displacing the other. Id. Accordingly, debit cards often

featured only Visa or Mastercard, leaving merchants with only

one routing choice for many debit transactions. See id.




4 Previously, Visa and Mastercard operated as membership associations
owned exclusively by member banks. Compl. ¶ 48.

                                    12
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 13 of 58



     In 2011, pursuant to the “Durbin Amendment,”5 the Federal

Reserve promulgated Regulation II (“Reg II”) and thereby

transformed the debit market. See id. ¶¶ 8–9, 51; Corner Post,

603 U.S. at 805. To improve routing choices for merchants

accepting debit, the Durbin Amendment required each debit card

to support at least two unaffiliated networks. Compl. ¶¶ 8, 51.

The Durbin Amendment also capped interchange fees paid to

regulated issuers. Id. ¶ 52; Corner Post, 603 U.S. at 805. With

a no-evasion rule, this interchange cap limited debit networks’

ability to incentivize issuers to switch networks, or fully to

compensate issuers’ switching costs. Compl. ¶ 52.

     Effective 2023, the Federal Reserve amended Reg II and

clarified that at least one debit network unaffiliated with the

front of card network must be enabled for CNP transactions (the

“2023 Amendment”). Id. ¶ 71 (referencing Debit Card Interchange

Fees and Routing, 87 Fed. Reg. 61217, 61230–32 (Oct. 11, 2022)

(codified at 12 C.F.R. § 235.7)). This clarification sought to

promote competition in e-commerce among debit networks. Id.

                             B. Visa Debit

     Visa is thriving. See id. ¶ 63. In 2022, Visa produced

global operating incomes totaling $18.8 billion with an



5 Congress passed the Durbin Amendment in 2010 and it became law as

part of the Dodd-Frank Wall Street Reform and Consumer Protection Act,
Pub. L. No. 111-203 (2010). Compl. ¶ 8. The Durbin Amendment is
complementary to the federal antitrust laws. 12 U.S.C. § 5303.

                                   13
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 14 of 58



operating margin of 64% globally and an operating margin of 83%

in North America. Id. Central to this success, Visa debit in the

United States produces Visa’s largest source of revenue

globally. Id. ¶ 64. Each year, on its United States debit

volume, Visa charges over $7 billion in network fees and earns

over $5.6 billion in net revenue. Id.

     For each debit transaction routed to Visa, the acquirer and

the issuer each pays a network fee to Visa. Id. ¶¶ 22, 43. The

acquirer also pays an interchange fee to the issuer. Id. ¶ 44.

Network fees for Visa debit vary based on the transaction type

but are generally lower for issuers than for acquirers, and in

most cases, significantly higher than those charged by the PIN

networks. Id. ¶¶ 43, 45, 68. In earning these network fees, Visa

incurs nearly zero incremental cost for each additional debit

transaction routed on the Visa network. Id. ¶ 65. Visa also

bears no financial risk for fraudulent debit transactions; the

merchant or the issuer bears that risk instead. Id.

     In 2012, Visa also began charging each enrolled acquirer a

fixed monthly fee, called the “Fixed Acquirer Network Fee”

(“FANF”). Id. ¶ 43. Visa subsequently raised the FANF twice. Id.

¶ 87. Visa prices an acquirer’s FANF based on factors such as

the number of locations the merchant operates and the merchant’s

volume of CNP transactions. Id. ¶ 43.

                    C. Alleged Market Definition

     The markets alleged to be relevant are two product markets

in the United States: (1) the market for general purpose debit

network services and (2) the submarket for general purpose

card-not-present debit network services. Id. ¶¶ 149–51.

                      1. Alleged Product Market

     The two-sided market for general purpose debit network

services allegedly includes “payment products and services” that

are accepted at numerous unrelated merchants and “that

facilitate the debit (i.e., withdrawal) of funds directly out of

a consumer’s bank account.” Id. ¶ 152. To be included, payment

networks must offer the four “minimum attributes of debit”:

(1) a rail that facilitates real-time transactions paid directly

from the consumer’s bank account; (2) the ability for the

consumer or the issuer to dispute and chargeback the

transaction; (3) payment guarantees for merchants; and (4) fraud

protections for all parties. Id. ¶¶ 152–53, 159. On that basis,

the alleged market for general purpose debit network services

includes both debit card networks and alternative debit

networks, such as fintech debit networks. See id. ¶¶ 152, 156.

     Based, however, on the contention that market participants

view other payment methods as unsuitable substitutes for debit,

the following methods of payment are excluded:

          General purpose credit card network services;

                                   15
    Case 1:24-cv-07214-JGK   Document 89    Filed 06/23/25   Page 16 of 58




          Network services      for     store   cards   and   other
           prepaid cards;

          Cash and check payments; and

          Interbank payment networks.

Id. ¶¶ 155, 157–60.

     Interbank payment networks are excluded because they

allegedly lack three out of the four minimum attributes of

debit: the ability for the consumer or the issuer to dispute and

chargeback the transaction; payment guarantees for merchants;

and fraud protections for all parties. Id. ¶¶ 153, 159. In

addition, ACH lacks real-time transaction rails, id. ¶ 115, and

RTP is available only for banks, see id. ¶ 61; The Clearing

House, RTP,

www.theclearinghouse.org/payment-systems/rtp/institution (last

visited June 18, 2025) (“RTP Website”).

                             2. CNP Submarket

     The Government defines the market for general purpose

card-not-present debit network services as “a narrower relevant

product market included within the broader” product market that

primarily services e-commerce transactions. Id. ¶ 161. This “CNP

submarket” includes both debit card and fintech debit networks,

but again excludes interbank payment networks. See id. ¶ 162.

                  C. Visa’s Alleged Monopoly Power

       The Government alleges that Visa possesses monopoly power

in the market for general purpose debit network services and the

CNP submarket. Id. ¶¶ 164–65, 174–75. For purposes of this

motion, Visa does not contest that allegation.

       Visa is the front of card brand for over 70% of debit card

payment volume. Id. ¶¶ 6, 53, 67, 179. Measured by the

percentage of all debit transactions, Visa enjoys a 60% market

share in the alleged market for general purpose debit network

services, and a 65% market share in the CNP submarket. Id.

¶¶ 6, 66, 164. In each alleged market, Mastercard has less than

25% market share, and no other competitor has more than a

single-digit percentage market share. See id. ¶¶ 103, 164. The

PIN networks collectively represent approximately 11% of all

debit transactions and only 5% of CNP debit transactions. Id.

¶ 103.

       The below table summarizes these market share allegations:

Product Market        Market Share     CNP Submarket           Market Share
Visa                  60%              Visa                    65%
Mastercard            25% or less      Mastercard              25% or less
Other Networks        About 15%        Other Networks          About 15%
       PIN Networks      11%                 PIN Networks          5%

See id. ¶¶ 6, 66, 103, 164.

       Visa has retained these market shares allegedly despite

imposing new fees (like the FANF) and the promulgation of Reg

                                     17
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 18 of 58



II. Id. ¶¶ 167, 175. Although Visa’s share of debit payment

volume dropped from approximately 63% in 2011 to approximately

56% in 2012, the year when Reg II first took effect, Visa

regained the lost market share within a few years. Id. ¶¶ 95–96,

167. More recently, in October 2023, Visa converted previously

optional fees charged to acquirers for digital commerce services

into a mandatory bundled fee, allegedly without a corresponding

loss in debit volume. See id. ¶ 175.

     Central to Visa’s alleged monopoly power, about 45% of Visa

CP transactions and an even higher share of Visa CNP

transactions cannot be routed to networks other than Visa and

are thus “non-contestable.” Id. ¶¶ 10, 58, 73, 79.

Non-contestable transactions exist because issuers have not

enabled PIN networks to process certain transaction types. See

id. ¶¶ 58, 92.

                         D. Visa’s Contracts

     With this alleged monopoly power, Visa allegedly coerces

merchants, acquirers, and issuers to enter into exclusive

dealing contracts with Visa. These contracts, the Government

says, amount to de facto exclusive dealing arrangements that

violate Sherman Act §§ 1 and 2. Id. ¶¶ 181–92, 198–202.

                         1. Routing Contracts

     Visa’s routing contracts with merchants and acquirers today

cover more than 180 of Visa’s largest merchants and acquirers,

                                   18
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 19 of 58



representing over 75% of Visa’s debit volume. Id. ¶¶ 13, 98.

Visa’s routing contracts require the merchant or acquirer to

route to Visa 90% to 100% of the merchant or acquirer’s eligible

debit transactions. Id. ¶¶ 12, 57, 70–76, 79, 87, 98. In some

cases, Visa also bargains for top position in the routing table,

a ranked list that determines which network a given debit

transaction should be routed to. Id. ¶ 76.

     To induce merchant and acquirer enrollment, Visa allegedly

creates an incentive structure that shares Visa’s alleged

monopoly profits but punishes noncompliance. See id. ¶¶ 12, 74.

First, Visa charges artificially high rack rates and introduces

fixed fees like the FANF. See id. ¶¶ 12, 79–81, 87. Then, with

routing contracts, Visa offers relief: discounted rack rates and

fixed fee waivers. Id. ¶¶ 78–81, 87. In some cases, Visa adds

credit incentives. Id. ¶¶ 77, 85. But, while providing

concessions with one hand, Visa allegedly extracts the right to

punish noncompliance with the other. Id. ¶¶ 76–78. Pursuant to

Visa’s routing contracts, subject only to limited safe harbors,

any volume shortfall gives Visa the right to revert back to rack

rates for all transactions, both contestable and

non-contestable. Id. ¶¶ 76, 78. Additionally, in many cases, any

volume shortfall gives Visa the right to terminate early the

entire contract and claw back any incentives that Visa had



                                   19
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 20 of 58



previously paid, including any credit incentives provided under

the contract. Id. ¶ 77.

     Because of this incentive structure, even some acquirer

processors that operate PIN networks have allegedly agreed to

routing deals with Visa. Id. ¶ 82. Those contracts allegedly

discourage acquirer processors from using PIN networks to

compete vigorously against Visa. Id.

     Visa’s routing contracts with merchants and acquirers

allegedly foreclose from competition at least 45% of total debit

volume in the United States. Id. ¶ 98. In so doing, Visa’s

routing contracts allegedly limit routing choice and deprive

Visa’s competitors of scale. Id. ¶¶ 13, 45, 57–59, 77–78, 98.

                          2. Issuer Contracts

     On the other side of the market, Visa enters into long-term

contracts with issuers that allegedly impose a variety of

restrictions on issuers. See id. ¶¶ 40, 88–94, 172.

     With some issuer contracts, Visa places direct restrictions

on the placement and enablement of other debit card networks.

See id. ¶ 88. For example, Visa’s contract with JPMorgan Chase

allegedly permits Chase to enable only one unaffiliated PIN

network on 90% of Visa debit cards issued by Chase. Id.

     With other issuer contracts, Visa allegedly achieves

similar results using volume targets. See id. ¶ 89. Included in

nearly 1,000 of Visa’s issuer contracts, volume targets offer

                                   20
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 21 of 58



incentives in exchange for the issuer’s commitment to grow the

issuer’s debit volume routed to Visa in line with Visa’s overall

debit growth in the United States. Id. Volume shortfalls,

however, require the issuer to pay significant monetary

penalties. Id. ¶¶ 90, 93. In some cases, noncompliant issuers

may owe Visa an early termination fee comprised of a

multimillion-dollar fixed fee plus a percentage of the benefits

the issuer has already earned. Id. ¶ 90. Debit volume targets

therefore incentivize issuers not to enable additional networks

on Visa debit cards and not to enable existing networks for

additional transaction types. Id. ¶ 91.

                  3. Alleged Exclusionary Effects

     With issuer contracts on one side, and merchant and

acquirer contracts on the other, Visa allegedly foreclosed

competition in such a substantial share of the relevant market

so as to adversely affect competition. See id. ¶ 100. Reinforced

by indirect network effects, Visa’s unmatched scale and volume

of non-contestable transactions allegedly prevent any rival

debit network from competing to earn a meaningful market share.

Id. ¶¶ 98–104. Lack of acceptance and usage, in turn, allegedly

ensnare rival networks in a vicious cycle that prevents growth,

improvement of features, and ultimately, effective competition

with Visa. Id. ¶¶ 101, 105, 142.



                                   21
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 22 of 58



     After the Durbin Amendment became law, smaller debit

networks allegedly attempted to outcompete Visa by offering

lower fees and improved features. Id. ¶ 104. But Visa’s

contracts allegedly foreclosed such competition by imposing

cliff pricing on merchants, acquirers, and issuers alike. Id.

¶¶ 76, 78, 81, 93. Under Visa’s alleged cliff pricing, Visa’s

prices increase dramatically when volume targets are not met,

namely, when transactions are routed to debit networks other

than Visa. Id.

     To overcome Visa’s alleged cliff pricing and win

transactions away from Visa, it is not enough for a PIN network

to outcompete Visa on the price of per-transaction network fees.

See id. ¶¶ 83, 102. The PIN network must also compensate

merchants, acquirers, and issuers for the cost of Visa’s

imposing rack rates on non-contestable volume, as well as any

other incentive clawbacks. Id. Moreover, the resulting lack of

sufficient transaction data inhibits PIN networks from offering

robust fraud protections equivalent to or better than the

protections provided by Visa or Mastercard. Id. ¶ 105. Thus,

Visa’s contracts allegedly make it nearly impossible for PIN

networks to win market share away from Visa. Id. ¶¶ 103, 140.

     Additionally, Visa’s contracts have allegedly thwarted the

intended effects of the Durbin Amendment and Reg II. See id.

¶¶ 95–96, 99, 167. For example, in 2023, Chase asked Visa for a

                                   22
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 23 of 58



contractual waiver to issue Visa debit cards with both Maestro

and Pulse enabled, as required to comply with the

2023 Amendment. Id. ¶ 107. Visa allegedly thought that granting

the waiver would increase competition for CNP volume. See id.

Taking stock, Visa granted Chase only a short-term waiver. Id.

But, with this leverage, Visa allegedly forced Chase to enter

into a Visa routing contract. Id.

     This strategy was not limited to Chase; as alleged, Visa

also strategized to renew other issuer contracts and threatened

issuers with monetary penalties and price increases to

discourage PINless enablement. Id. ¶¶ 99, 173. With merchants

and acquirers, Visa allegedly strategized to secure more volume

under routing deals, and to discourage switching by including

early termination fees. Id. ¶ 99.

     All told, by the end of 2022, at least 75% of Visa’s debit

volume (and 80% of its CNP debit volume) were allegedly

insulated from competition because of Visa’s contracts. Id.

¶ 141. That allegedly foreclosed from competition at least 45%

of all debit transactions and over 55% of CNP debit transactions

in the United States. Id. ¶¶ 19, 140–41.

                   E. Alleged Fintech Suppression

     The Government also alleges that Visa partners with

competitors and potential competitors unlawfully to dissuade

competition. Id. ¶ 16. Using its alleged monopoly power, Visa

                                   23
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 24 of 58



allegedly offers customized incentives totaling up to hundreds

of millions of dollars annually to partners in exchange for

agreements not to develop a competing product and not to compete

in certain ways. Id. ¶¶ 21, 110–12, 135. In addition, Visa

allegedly obtains protections against disparagement,

discrimination, and disintermediation. Id. ¶ 112, 135. For these

reasons, the Government alleges that Visa’s contracts with

competitors and potential competitors “amount to a horizontal

product market division.” Id. ¶¶ 112, 135, 147.

                      1. Staged Digital Wallets

     In forming partnerships to stymie threats to Visa debit,

Visa allegedly prioritized staged digital wallets. Id. ¶ 121.

Starting in around 2016, to prevent such wallets from competing,

Visa allegedly threatened to impose a staged digital wallet fee.

Id. ¶ 125. In response, all staged digital wallets signed deals

with Visa. Id. The alleged examples are PayPal and Square. Id.

¶¶ 119–32.

     With PayPal, in 2016, Visa allegedly used the threat of

staged digital wallet fees and high rack rates to induce PayPal

to enter into an expansive Visa routing contract. Id. ¶¶ 119–22.

In around 2015, Visa allegedly also stymied PayPal’s entering

into partnerships with brick-and-mortar merchants by imposing a

restriction on ACH-funded transactions when the PayPal customer

had a Visa card in their PayPal wallet. See id. ¶ 123. Visa

                                   24
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 25 of 58



relaxed these restrictions in 2021, but allegedly required

information sharing to monitor PayPal’s product success. Id. In

2022, PayPal and Visa entered into a new ten-year contract that

allegedly limits PayPal’s incentives and ability to disrupt the

market for debit network services. Id. ¶ 124. To this day, Visa

allegedly restricts PayPal’s in-person ACH-funded transactions

to a QR-code model. Id. ¶ 123.

     With Square, Visa allegedly entered into a series of

contracts that allegedly foreclosed Square from competing

aggressively against Visa and prevented Square from developing a

fintech debit network. See id. ¶¶ 126–32. When Visa first

entered into a contract with Square in 2014, Visa allegedly

insisted on the right to terminate for convenience to punish any

efforts to compete with Visa. See id. ¶¶ 127–29. In 2016, Visa

allegedly threatened termination to prevent Square from

launching a new product that would enable users to store

preloaded funds. See id. ¶¶ 130–31. More recently, when Square

launched Cash App Pay, a consumer-to-merchant payment service,

Visa allegedly used the threat of staged digital wallet fees to

coerce Square: to route 97% of Cash App Pay transactions to

Visa; to preference Visa in signup flow and default settings;

and not to steer customers to ACH. Id. ¶ 132.




                                   25
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 26 of 58



                        2. Other Fintech Firms

     Using incentive-laden contracts, Visa allegedly also guards

against disintermediation by other fintech firms. Id. ¶¶ 112,

133, 135. By forming custom partnerships and entering into

routing contracts with Big Tech companies like Amazon and Apple,

Visa allegedly extracts non-disintermediation and other future

commitments from some of Visa’s largest merchants. Id. ¶ 135.

Visa also benefits by allegedly obtaining control over

e-commerce acceptance and online payments flow in the partners’

systems. Id. ¶ 134.

     Apple is the alleged example. Id. ¶ 118. In response to

Apple’s threat, Visa allegedly entered into deals whereby Apple

agreed: not to develop or deploy payment functionality with the

aim of competing with Visa; not to build, support, or introduce

payment technologies that disintermediate Visa; not to provide

incentives “with the intent of disintermediating Visa or

inciting customers to cease using Visa Cards”; and not to steer

customers to third-party payment methods such as ACH.

Id. ¶ 136. In exchange, Visa allegedly provided Apple with

reduced merchant fees and payments that, in 2023, totaled

hundreds of millions of dollars. Id.

                      F. Effects on Competition

     The Government alleges that, by engaging in the conduct

described above, Visa harmed competition and innovation in the

                                   26
    Case 1:24-cv-07214-JGK    Document 89   Filed 06/23/25   Page 27 of 58



United States market for general purpose debit network services

and the CNP submarket. Id. ¶¶ 138–46. The Government also

alleges that Visa’s alleged conduct produces no procompetitive

benefits that outweigh the anticompetitive effects or that

cannot be obtained through less restrictive means. Id. ¶ 147.

The Government further contends that Visa’s agreements with

current and potential competitors are not ancillary to the

contracting parties’ vertical relationship, but rather, simply

divide up the relevant product markets. Id.

                         III. Legal Standard

                             A. Sherman Act § 1

     Section 1 of the Sherman Act forbids “[e]very contract

. . . in restraint of trade or commerce among the several

States.” 15 U.S.C. § 1. Despite this broad language, § 1 “was

intended to prohibit only unreasonable restraints of trade.”

Nat’l Collegiate Athletic Ass’n v. Bd. of Regents of Univ. of

Okla., 468 U.S. 85, 98 (1984). Therefore, “[t]o prove a § 1

violation, a plaintiff must demonstrate: (1) a combination or

some form of concerted action between at least two legally

distinct economic entities that (2) unreasonably restrains

trade.” Geneva Pharms. Tech. Corp. v. Barr Labs. Inc., 386 F.3d

485, 506 (2d Cir. 2004). “The overarching standard is whether

[the] defendant[’s] actions diminish overall competition, and



                                     27
    Case 1:24-cv-07214-JGK    Document 89   Filed 06/23/25   Page 28 of 58



hence consumer welfare.” K.M.B. Warehouse Distribs., Inc. v.

Walker Mfg. Co., 61 F.3d 123, 127 (2d Cir. 1995).

     “Some restraints are per se unreasonable”—that is, “under

no circumstance will they be held to be lawful.” U.S. Airways,

Inc. v. Sabre Holdings Corp., 938 F.3d 43, 54 (2d Cir. 2019).

“If a restraint is not per se unreasonable, it is analyzed under

the rule of reason” to determine whether the procompetitive

effects outweigh the anticompetitive effects. See id. at 55.

                             B. Sherman Act § 2

     Section 2 of the Sherman Act makes it unlawful for a person

to “monopolize” or “attempt to monopolize” interstate trade or

commerce. 15 U.S.C. § 2. Under § 2, monopoly power means “the

power to control prices or exclude competition.” United States

v. E.I. du Pont De Nemours & Co., 351 U.S. 377, 391 (1956).

     To establish monopolization in violation of § 2, the

plaintiff must prove that “the defendant: (1) possessed monopoly

power in the relevant market; and (2) willfully acquired or

maintained that power.” Tops Mkts., Inc. v. Quality Mkts., Inc.,

142 F.3d 90, 97 (2d Cir. 1998) (citing United States v. Grinnell

Corp., 384 U.S. 563, 570–71 (1966)). Hence, § 2 does not outlaw

the acquisition of monopoly power through “growth or development

as a consequence of a superior product, business acumen, or

historic accident.” Grinnell Corp., 384 U.S. at 570–71. To be

found unlawful, “the possession of monopoly power” must be

                                     28
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 29 of 58



“accompanied by an element of anticompetitive conduct.” Verizon

Commc’ns Inc. v. Law Offs. of Curtis V. Trinko, LLP, 540 U.S.

398, 407 (2004).

     To establish attempted monopolization in violation of § 2,

the plaintiff must show that the defendant: “(1) engaged in

predatory or anticompetitive conduct with (2) a specific intent

to monopolize and (3) a dangerous probability of achieving

monopoly power.” Spectrum Sports Inc. v. McQuillan, 506 U.S.

447, 456 (1993).

     Under § 2, courts must avoid “tightly compartmentalizing

the various factual components” of the plaintiff’s claims and

“wiping the slate clean after scrutiny of each.” City of Groton

v. Conn. Light & Power Co., 662 F.2d 921, 928–29 (2d Cir. 1981)

(quoting Cont’l Ore Co. v. Union Carbide & Carbon Corp., 370

U.S. 690, 699 (1962)). When aggregated, however, independently

lawful acts rarely cause harm to competition. See Pac. Bell Tel.

Co. v. Linkline Commc’ns, Inc., 555 U.S. 438, 457 (2009).

Therefore, the proper inquiry is not whether “there is a

fraction of validity to each of [the plaintiff’s] claims.” City

of Groton, 662 F.3d at 928–29. “The proper inquiry is whether,

qualitatively, there is a synergistic effect.” Id.

                             B. Rule 12(b)(6)

     In deciding a Rule 12(b)(6) motion to dismiss for failure

to state a claim, the Court must accept the allegations in the

                                    29
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 30 of 58



complaint as true and draw all reasonable inferences in the

plaintiff’s favor. McCarthy v. Dun & Bradstreet Corp., 482 F.3d

184, 191 (2d Cir. 2007). The Court’s function on a motion to

dismiss is “not to weigh the evidence that might be presented at

a trial but merely to determine whether the complaint itself is

legally sufficient.” Goldman v. Belden, 754 F.2d 1059, 1067 (2d

Cir. 1985).

     To survive a motion to dismiss, the complaint must contain

“enough facts to state a claim to relief that is plausible on

its face.” Bell Atl. Corp. v. Twombly, 550 U.S. 544, 570 (2007).

In particular, a claim brought under the Sherman Act must

plausibly (1) define the relevant market and (2) allege conduct

in violation of the antitrust laws (3) that harmed competition.

See United States v. Microsoft Corp., 253 F.3d 34, 58–59 (D.C.

Cir. 2001) (en banc) (per curiam); Concord Assocs., L.P. v. Ent.

Props. Tr., 817 F.3d 46, 52 (2d Cir. 2016). “A claim has facial

plausibility when the plaintiff pleads factual content that

allows the court to draw the reasonable inference that the

defendant is liable for the misconduct alleged.” Ashcroft v.

Iqbal, 556 U.S. 662, 678 (2009). While the Court should construe

the factual allegations in the light most favorable to the

plaintiff, “the tenet that a court must accept as true all of

the allegations contained in a complaint is inapplicable to

legal conclusions.” Id.

                                   30
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 31 of 58



     When presented with a motion to dismiss pursuant to Rule

12(b)(6), the Court may consider documents that are referenced

in the complaint, documents that the plaintiff relied on in

bringing suit and that are either in the plaintiff’s possession

or that the plaintiff knew of when bringing suit, or matters of

which judicial notice may be taken. See Chambers v. Time Warner,

Inc., 282 F.3d 147, 153 (2d Cir. 2002).

                             IV. Discussion

     Visa’s three arguments for dismissal are addressed in turn.

                         A. Market Definition

     Visa argues initially that the Government’s alleged product

market is implausible because it excludes interbank payment

networks such as ACH and RTP. Mem. of Law in Support (“Br.”) at

12–17, ECF No. 39; Visa’s Reply (“Rep.”) at 1–3, ECF No. 60. But

the Government has alleged several characteristics that

plausibly restrict the reasonable interchangeability of use

between debit networks and interbank payment networks, and thus

a plausible product market.

     “To state a claim under either [§] 1 or [§] 2 of the

Sherman Act, a plaintiff must plausibly allege that the

defendant[’s] anticompetitive conduct restricted competition

within a relevant market.” See Regeneron Pharms., Inc. v.

Novartis Pharma AG, 96 F.4th 327, 338 (2d Cir. 2024). “For

antitrust purposes, the concept of a market has two components:

                                   31
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 32 of 58



a product market and a geographic market.” Concord Assocs., 817

F.3d at 52. Visa’s motion to dismiss challenges only the

Government’s proposed product market.

     The relevant product market includes “all products

reasonably interchangeable by consumers for the same purposes.”

United States v. Am. Express Co., 838 F.3d 179, 196 (2d Cir.

2016), aff’d sub nom. Ohio v. Am. Express Co., 585 U.S. at 540.

At the pleadings stage, the alleged product market must “bear a

rational relation to the methodology courts prescribe to define

a market” and include a “plausible explanation as to why a

market should be limited” to exclude possible substitutes. Todd

v. Exxon Corp., 275 F.3d 191, 200 (2d Cir. 2001).

     To discern the boundaries of the relevant product market,

courts look to “the reasonable interchangeability of use or the

cross-elasticity of demand between the product itself and

substitutes for it.” Brown Shoe Co. v. United States, 370 U.S.

294, 325 (1962). “Two products are reasonably interchangeable

where there is sufficient cross-elasticity of demand—that is,

where consumers would respond to a slight increase in the price

of one product by switching to another product.” Regeneron, 96

F.4th at 339; see also du Pont, 351 U.S. at 394–95.

     “This is a relatively permissive pleading standard.”

Regeneron, 96 F.4th at 339. Courts should therefore “hesitate to



                                   32
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 33 of 58



grant motions to dismiss for failure to plead a relevant product

market.” Todd, 275 F.3d at 199–200.

                  1. Reasonable Interchangeability

     Visa argues that the alleged product market is implausible

because the excluded interbank payment networks perform the same

core function as the included debit networks: transferring funds

between bank accounts. But Visa places “improper weight on the

functional, rather than economic, similarities between”

interbank payment networks and debit networks. See Regeneron, 96

F.4th at 338–40. Moreover, Visa improperly devalues the

allegation that interbank payment networks lack at least three

out of the four alleged minimum characteristics of debit. See

Compl. ¶ 159. Evaluated under the established legal frameworks

for defining the relevant product market, the complaint alleges

plausibly that debit networks and interbank payment networks

“are not economic substitutes.” See Regeneron, 96 F.4th at 340.

                  (a) Hypothetical Monopolist Test

     To define the relevant market, courts often apply the

“hypothetical monopolist test.” Am. Express Co., 838 F.3d at

198. The test “imagin[es] that a hypothetical monopolist has

imposed a small but significant non-transitory increase in price

(‘SSNIP’) within the proposed market.” Id. “If the hypothetical

monopolist can impose a SSNIP without losing so many sales to

other products as to render the SSNIP unprofitable, then the

                                   33
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 34 of 58



proposed market is the relevant market.” Regeneron, 96 F.4th at

339. But “if consumers are able and inclined to switch away from

the products in the proposed market in sufficiently high numbers

to render the SSNIP unprofitable, then the proposed market

definition is likely too narrow and should be expanded.” Am.

Express Co., 838 F.3d at 199. Additionally, courts considering

“a two-sided market must consider the feedback effects inherent

on the platform.” See id. at 200.

     In this case, the complaint alleges plausibly that a

hypothetical monopolist could impose a profitable SSNIP in the

proposed product market. This is because demand is plausibly

alleged to be bilaterally inelastic. See Compl. ¶ 155. On the

cardholder side, tens of millions of Americans allegedly prefer

or must rely on debit. Id. ¶¶ 27, 157, 160. Some consumers, for

example, prefer the spending discipline of using only available

funds; others are unable to obtain credit. Id. That creates

inelastic merchant demand because merchants “do not want to risk

lost sales by not accepting many consumers’ preferred payment

method.” Id. ¶ 155; see also Am. Express Co., 838 F.3d at 197–98

(emphasizing the interdependence between the two sides of a card

payments network). And in debit, where merchants go, acquirers

must follow. See Compl. ¶ 155.

     Moreover, it is plausible that the four alleged minimum

attributes of debit sufficiently restrict the cross-elasticity

                                   34
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 35 of 58



of demand between debit networks and other payment networks such

that a hypothetical monopolist could impose a profitable SSNIP

on general purpose debit network services. Id. ¶¶ 155, 157–60.

The complaint alleges specifically that no other type of payment

network offers all four of the minimum attributes of debit: (1)

real-time transaction rails; (2) dispute and chargeback

capabilities; (3) merchant payment guarantees; and (4) fraud

protections. Id. ¶¶ 152–53, 157–60. In particular, the real-time

interbank payment networks lack (2), (3), and (4), and ACH lacks

all four. Id. ¶¶ 152–53, 155, 159. In addition, RTP is alleged

to be available only for banks. See id. ¶ 61; RTP Website.

     In response to a SSNIP, consumers might continue to use

debit networks over interbank payment networks because consumers

are reluctant to give up the ability to charge back fraudulent

or defective purchases. Id. ¶ 159. The same may be true of fraud

protections. Id. Consumers may also be averse to the additional

frictions associated with interbank payment networks (like ACH’s

account verification and slower processing speed). Id. RTP is

allegedly not even available to consumers. See id. ¶ 61; RTP

Website.

     Likewise, in response to a SSNIP, merchants and acquirers

might continue to use debit networks over interbank payment

networks because of inelastic consumer demand for debit. Id.

¶¶ 155, 159. Moreover, lack of fraud detection and merchant

                                   35
     Case 1:24-cv-07214-JGK   Document 89    Filed 06/23/25   Page 36 of 58



payment guarantees could increase costs related to fraud and

nonpayment; those increased costs might sufficiently offset

savings recouped from interbank payment networks’ lower fees so

as to make switching undesirable. See id.

      Although both debit networks and real-time interbank

payment networks offer real-time transaction rails, that “does

not automatically mean that [the products] compete in the same

market.” See Regeneron, 96 F.4th at 340. Somewhere across the

spectrum of function and price, products divide into separate

product markets. See id. at 339–40 (finding plausible the

allegation that vials and prefilled syringes “contain[ing] the

same medicines” competed in different product markets); Fed.

Trade Comm’n (“FTC”) v. Tapestry, Inc., 755 F. Supp. 3d 386, 416

(S.D.N.Y. 2024) (collecting cases). Moreover, given other

economic factors, even functionally identical products—like

brand-name and generic versions of the same drug—can sort into

different product markets. Geneva Pharms., 386 F.3d at 496–97.

Because the complaint in this case alleges plausibly and with

specificity that functional differences between debit networks

and interbank payment networks are features that delineate the

relevant product market, the Government has alleged a plausible

product market.6


6 In arguing to the contrary, Visa relies on inapposite cases. See, e.g.,
Jacobs v. Tempur-Pedic Int’l Inc., 626 F.3d 1327, 1338 (11th Cir. 2010)
(finding that “skimpy allegations” failed to define a plausible product

                                     36
     Case 1:24-cv-07214-JGK   Document 89    Filed 06/23/25   Page 37 of 58



      At bottom, what matters is “reasonable interchangeability

in the eyes of consumers.” United States v. Visa U.S.A., Inc.,

163 F. Supp. 2d 322, 335 (S.D.N.Y. 2001), aff’d, 344 F.3d at

244. And the complaint explains plausibly that, in response to a

SSNIP on general purpose debit network services, consumers,

merchants, and banks would continue to use debit networks rather

than to substitute interbank payment networks, despite their

limited “real-world functional similarities.” See Regeneron, 96

F.4th at 339–40. The complaint therefore alleges plausibly that

the market for general purpose debit network services is the

relevant product market. See id.

                          (b) Practical Indicia

      To define the relevant product market, courts also “look to

practical indicia of market boundaries to identify whether two

products are economic substitutes.” Id. at 339. These so-called

Brown Shoe factors “can include ‘industry or public recognition

of the market as a separate economic entity, the product’s

peculiar characteristics and uses, unique production facilities,

distinct customers, distinct prices, sensitivity to price

changes, and specialized vendors.’” Id. (quoting Brown Shoe, 370

U.S. at 325 & collecting cases). “This list is neither mandatory


market); Hicks v. PGA Tour, Inc., 897 F.3d 1109, 1121–22 (9th Cir. 2018)
(rejecting proposed submarkets that “omit[ted] many economic substitutes”);
Glob. Disc. Travel Servs., LLC v. Trans World Airlines, Inc., 960 F. Supp.
701, 706 (S.D.N.Y. 1997) (declining to accept “a relevant product market in a
single brand product”).

                                     37
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 38 of 58



nor exhaustive.” Alaska Elec. Pension Fund v. Bank of Am. Corp.,

306 F. Supp. 3d 610, 620 (S.D.N.Y. 2018).

     In this case, the practical indicia bolster the

plausibility of the Government’s proposed market. In particular,

“industry or public recognition” of the debit market “as a

separate economic entity” provides strong support. See Brown

Shoe, 370 U.S. at 325. Industry recognition is significant

because “economic actors usually have accurate perceptions of

economic realities.” Todd, 275 F.3d at 205.

     Visa’s own documents indicate that the payment networks

industry distinguishes between debit and other methods of

payment. See Br., Ex. 3 at 5, ECF No. 39-3; see also United

States v. Google LLC, 747 F. Supp. 3d 1, 113 (D.D.C. 2024)

(“Google itself recognizes general search services as a distinct

product and separate market.”). Similarly, the providers of RTP

and FedNow describe their real-time interbank payment networks

not as substitutes for debit networks, but rather, as a tool

that financial institutions can use to build debit networks. See

RTP Website; The Federal Reserve, About the FedNow® Service,

www.frbservices.org/financial-services/fednow/about.html (last

visited June 18, 2025).

     Other practical indicia also support the Government’s

proposed market definition. See Regeneron, 96 F.4th at 339.

Debit is alleged to have peculiar characteristics–the four

                                   38
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 39 of 58



minimum attributes of debit—that distinguish debit networks from

other payment services. Compl. ¶¶ 152–53. Debit networks are

also alleged to have distinct customers, including, on the

cardholder side, consumers that are ineligible for credit. Id.

¶ 27. In addition, debit networks allegedly set distinct prices

by charging network fees, imposing fixed fees on merchants and

acquirers, and setting interchange fees for unregulated issuers.

Id. ¶¶ 43–44; see also FTC v. Meta Platforms, Inc., 654 F. Supp.

3d 892, 918–19 (N.D. Cal. 2023) (weighing a distinct pricing

model in favor of the existence of an antitrust market).

Moreover, the complaint alleges that whereas debit networks

process a variety of transactions at “numerous, unrelated

merchants,” interbank debit networks primarily process

“recurring fixed payments like mortgage and tuition payments.”

Compl. ¶¶ 152, 159.

     Taken together, the practical indicia alleged in or

referenced by the complaint suggest plausibly that debit

networks are a distinct type of payment service. Accordingly,

the complaint alleges plausibly that debit networks and

interbank payment networks “are not economic substitutes.” See

Regeneron, 96 F.4th at 341.

                      2. Visa’s Counterarguments

     Visa sees a logical inconsistency in the allegation that

fintech debit networks compete with Visa debit, whereas

                                   39
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 40 of 58



interbank payment networks, which fintech debit networks use to

transfer funds, do not. This argument, however, misapprehends

the relevant allegations. The complaint alleges that fintech

debit networks use interbank payment networks as “lower-cost

alternatives to Visa’s debit offering” when transferring funds

between banks. Compl. ¶ 61. That only strengthens the

complaint’s allegation that the end users of debit network

services—consumers and merchants—view as reasonable substitutes

for Visa only those networks, like fintech debit networks, that

provide “the same functionality to consumers and merchants.” See

id. ¶¶ 60–61, 156. Interbank payment networks do not provide the

same functionality as Visa debit because even real-time

interbank payment networks lack three out of the four alleged

minimum attributes of debit. Id. ¶¶ 152–53, 159. Visa’s

counterarguments are therefore without merit.

     In sum, the Government has alleged a plausible product

market. See Regeneron, 96 F.4th at 339–40. “Market definition is

a deeply fact-intensive inquiry” that “generally requires

discovery,” Todd, 275 F.3d at 199–200, and this case is not an

exception. Accordingly, Visa’s motion to dismiss for failure to

allege a plausible product market is denied.7




7 Because Visa does not separately challenge the plausibility of the
proposed CNP submarket, the complaint’s allegations regarding the CNP
submarket likewise survive Visa’s motion to dismiss.

                                   40
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 41 of 58



                   B. Exclusive Dealing Contracts

     Visa’s second argument is that the complaint fails to

allege anticompetitive conduct and thus harm to competition

because the complaint does not allege that Visa discounted its

prices for Visa debit to below its costs. Br. at 17–20; Rep. at

4–7, 10–11. Advocating for a rule of per se legality, Visa

contends that the price–cost test “require[s] the Government to

allege that Visa has set prices below its costs, full stop.” Br.

at 18.

     But that argument overlooks all of the other

anticompetitive conduct alleged in the complaint. Moreover,

Visa’s argument misconstrues the gravamen of the complaint. The

Government does not allege that Visa violated the Sherman Act by

setting prices too low, namely, by using predatory volume

discounts; quite to the contrary, the Government contends that

Visa’s contracts deprived rivals of their ability to compete and

thus allowed Visa to charge supracompetitive prices. Gov’t’s

Opposition (“Opp.”) at 14, ECF No. 52.

     Those allegations show plausibly that the legality of

Visa’s alleged conduct should be evaluated “under the rule of

reason to determine whether the ‘probable effect’ of such

conduct was to substantially lessen competition,” rather than

merely disadvantage rivals. See ZF Meritor, LLC v. Eaton Corp.,

696 F.3d 254, 269 (3d Cir. 2012) (quoting Tampa Elec. Co. v.

                                   41
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 42 of 58



Nash. Coal Co., 365 U.S. 320, 328–29 (1961)); Microsoft, 253

F.3d at 69. At this stage, “[t]he price-cost test is not

dispositive” because the complaint “do[es] not allege that price

itself functioned as the exclusionary tool.” See ZF Meritor, 696

F.3d at 269, 281.

                         1. Exclusive Dealing

     Under an exclusive dealing agreement, the buyer agrees to

purchase specific goods or services only from the seller for a

set period of time. Id. at 270. “The primary antitrust concern

with exclusive dealing arrangements is that they may be used by

a monopolist to strengthen its position, which may ultimately

harm competition.” Id. (citing United States v. Dentsply Int’l,

Inc., 339 F.3d 181, 191 (3d Cir. 2005)). Such conduct can

deprive “rivals of the opportunity to achieve the minimum

economies of scale necessary to compete.” Id. at 271.

     Because courts look to the actual effects of exclusive

dealing arrangements, the federal antitrust statutes recognize

“de facto exclusive dealing claims.” See id. at 270 (Sherman Act

§§ 1 & 2, Clayton Act § 3); Tampa Elec., 365 U.S. at 326–27

(Clayton Act § 3).8 Recognizing that exclusive dealing agreements

are vertical agreements that can produce many procompetitive




8 But see Virgin Atl. Airways Ltd. v. British Airways PLC, 257 F.3d
256, 264 (2d Cir. 2001) (reserving judgment on “whether a § 2 analysis
may be neatly imported into a relevant § 1 analysis”).

    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 43 of 58



benefits, courts evaluate their legality under the rule of

reason. ZF Meritor, 696 F.3d at 271; CDC Techs., Inc. v. IDEXX

Labs., Inc., 186 F.3d 74, 80 (2d Cir. 1999); Roland Mach. Co. v.

Dresser Indus., Inc., 749 F.2d 380, 393–94 (7th Cir. 1984).

     To be held unlawful under the rule of reason, an exclusive

dealing arrangement must “foreclose competition in such a

substantial share of the relevant market so as to adversely

affect competition.” ZF Meritor, 696 F.3d at 271; Microsoft, 253

F.3d at 69–70. Courts “also analyze the likely or actual

anticompetitive effects of the exclusive dealing arrangement,

including whether there was reduced output, increased price, or

reduced quality in goods or services.” Eisai, Inc. v. Sanofi

Aventis U.S., LLC, 821 F.3d 394, 403 (3d Cir. 2016); see also

MacDermid Printing Sols. LLC v. Cortron Corp., 833 F.3d 172, 183

(2d Cir. 2016) (generally requiring “evidence of changed prices,

output, or quality”). But there is no set formula, and courts

must “look at the practical effect of [the] exclusive dealing

arrangements” in any given case. McWane, Inc. v. FTC, 783 F.3d

814, 834 (11th Cir. 2015).

                        2. The Price-Cost Test

     The price-cost test shields genuine price discounts from

claims of predatory pricing. Brooke Grp. Ltd. v. Brown &

Williamson Tobacco Corp., 509 U.S. 209, 222–24 (1993). When the

price-cost test applies, the plaintiff must prove that the

                                   43
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 44 of 58



defendant’s prices “are below an appropriate measure of [the

defendant’s] costs.” Id. at 222.

     To avoid chilling procompetitive conduct, courts apply the

price-cost test not only to predatory pricing claims, but also

to claims alleging that the defendant’s actions directed at

price itself excluded rivals from the relevant market. See

Weyerhaeuser Co. v. Ross-Simmons Hardwood Lumber Co., Inc., 549

U.S. 312, 325 (2007) (alleged predatory bidding); linkLine

Commc’ns, 555 U.S. at 451–54 (alleged price squeeze). Doing so

recognizes that “cutting prices in order to increase business

often is the very essence of competition,” see Matsushita Elec.

Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 594 (1986), and

that “[l]ow prices benefit consumers regardless of how those

prices are set,” see Atl. Richfield Co. v. USA Petrol. Co., 495

U.S. 328, 340 (1990).

                   3. Exclusive Dealing and Price

     Discounts conditioned on exclusivity have required courts

to “grapple[] with the question of when to apply the price-cost

test.” FTC v. Syngenta Crop Prot. AG, 711 F. Supp. 3d 545, 572–

76 (M.D.N.C. 2024) (surveying the case law). In ZF Meritor, the

Court of Appeals for the Third Circuit “balance[d] the important

concerns the Supreme Court has identified in over-regulating

price-cutting schema, and under-regulating exclusive dealing.”

Id. at 575. The court concluded that “exclusive dealing

                                   44
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 45 of 58



arrangements can exclude equally efficient (or potentially

equally efficient) rivals, and thereby harm competition,

irrespective of below-cost pricing.” ZF Meritor, 696 F.3d at

281. But the court further held that “the price-cost test may be

utilized as a specific application of the rule of reason” in

exclusive dealing cases. Id. at 273 (citing Concord Boat Corp.

v. Brunswick Corp., 207 F.3d 1039, 1060–63 (8th Cir. 2000)).

Doing so is appropriate, the court determined, when “price is

the clearly predominant mechanism of exclusion.” Id. at 275.

Conversely, when the defendant’s alleged practices include one

or more significant non-price elements of exclusion, the

price-cost test’s safe harbor need not apply. See id. at 279–81.

     After ZF Meritor was issued, other circuit courts of appeal

have cited the decision favorably.9 Moreover, numerous district

courts have expressly applied the “the clearly predominant

mechanism of exclusion” standard.10 In this case, the parties

both cite ZF Meritor favorably and appear to agree that the ZF

F. Supp. 3d 922, 1016–17 (D. Kan. 2021), aff’d, 44 F.4th 959, 987–88
(10th Cir. 2022) (approving of the district court’s application of the
ZF Meritor standard in a multi-district litigation transferred from

and applying the rule of reason to de facto exclusive dealing
arrangements).

Meritor standard strikes an appropriate balance between the

price-cost test and the rule of reason applicable to exclusive

dealing claims. Br. 20; Opp. 14–15. The Court therefore

considers whether price is alleged to be the clearly predominant

mechanism of exclusion.

                    4. Sufficiency of Allegations

     Under the ZF Meritor standard, the Government has alleged a

plausible exclusive dealing claim under Sherman Act §§ 1 and 2.

To prevail on an exclusive dealing claim brought under § 1, the

plaintiff must show that the defendant’s practices amounted to

exclusive dealing arrangements that “foreclose[d] competition in

such a substantial share of the relevant market so as to

adversely affect competition.” ZF Meritor, 696 F.3d at 271

(citing Tampa Elec., 365 U.S. at 328). Exclusive dealing

arrangements also violate § 2 when the overall practice

constitutes “willful acquisition or maintenance of [monopoly]

power.” Dial Corp., 165 F. Supp. 3d at 34, 36–37. At the

pleadings stage, the defendant’s anticompetitive conduct and

resulting harm to competition must be plausibly alleged. See

Twombly, 550 U.S. at 570.

     In assessing whether the defendant’s actions substantially

foreclosed competition, courts consider the following factors:

(1) significant market power by the defendant; (2) substantial

foreclosure; (3) contracts of sufficient duration to prevent

                                   46
     Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 47 of 58



meaningful competition by rivals; (4) likely or actual

anticompetitive effects considered in light of any

procompetitive effects; (5) whether there is evidence that the

dominant firm engaged in coercive behavior; (6) the ability of

customers to terminate the agreements; and (7) the use of

exclusive dealing by the defendant’s competitors. ZF Meritor,

696 F.3d at 271–72 (collecting cases). For purposes of this

motion, relying solely on the price-cost test, Visa contests

only the fourth factor: likely or actual anticompetitive

effects. Thus, to survive Visa’s motion to dismiss, the

complaint must allege plausibly that Visa’s contracts excluded

rivals from the relevant market through one or more significant

non-price mechanisms. See id. at 275; Syngenta, 711 F. Supp. 3d

at 576.

     The complaint makes such allegations. The thrust of the

complaint is that Visa’s loyalty scheme, unfurled through Visa’s

contracts on both sides of the relevant market, unreasonably

restrained competition and grew or maintained Visa’s monopoly in

debit by excluding rivals through mechanisms linked only

indirectly to price. Recognizing its monopoly power and leverage

over non-contestable transactions in particular, Visa allegedly

increased its rack rates and introduced new fixed fees.11 See



11The mere existence of non-contestable volume may be the product of
“growth or development as a consequence of a superior product.”

Compl. ¶¶ 12, 22, 76–87, 102. Additionally, to grow its

non-contestable debit volume, Visa allegedly induced and

threatened issuers like Chase to disable PIN networks. See id.

¶¶ 88–94, 99, 107, 173. Visa then allegedly used its dominant

position and artificial incentive structure to coerce customers

into exclusive dealing contracts. See id. ¶¶ 198–202; Dentsply,

399 F.3d at 184 (explaining that, “if faced with an ‘all or

nothing’ choice,” customers “may accede to the dominant firm’s

wish for exclusive dealing”). These “long-term” contracts

included cliff pricing, clawback provisions, and other penalties

that, in effect, took away the ability of customers to terminate

the agreements. See Compl. ¶¶ 40, 75–79, 90–93; In re

Surescripts, 608 F. Supp. 3d at 646 (explaining that clawback

provisions can “greatly amplif[y] the [loyalty] scheme’s

exclusionary effect”).

     All told, Visa’s loyalty program allegedly foreclosed from

competition at least 45% of all debit transactions and over 55%

of CNP debit transactions in the United States—an amount of

foreclosure sufficient to violate the Sherman Act. See Compl.

¶¶ 19, 140–41; Microsoft, 253 F.3d at 70. Visa’s contracts



Grinnell Corp., 384 U.S. at 571. But monopoly power, even when
lawfully obtained, may not be wielded to exclude competitors in ways
that have the probable effect of harming the competitive process. See
Dentsply, 399 F.3d at 196; Syngenta, 711 F. Supp. 3d at 576–77. That
general rule is especially important when the defendant “has no true
competitor.” See Google, 747 F. Supp. 3d at 144.

allegedly also heightened barriers to entry in a two-sided

market naturally insulated from competition. See Compl. ¶¶ 5,

55, 154; In re Surescripts, 608 F. Supp. 3d at 645 (recognizing

that “[a]chieving critical mass” presents “a barrier to entry

for start-ups in many two-sided markets”); see also Syngenta,

711 F. Supp. 3d at 576–77 (applying the rule of reason where the

alleged monopolists “exacerbate[d] the already high” entry

costs). Such effects, in turn, allegedly prevented PIN networks

from gaining the scale necessary to improve features like fraud

protection, which could lead to increased enablement of PIN

networks and thus competition for debit transactions. See Compl.

¶¶ 101, 105. In sum, the crux of the complaint is not that Visa

used volume discounts to harm rivals, but rather, that Visa used

its dominant position in the relevant market to coerce customers

into exclusive dealing contracts that prevented rivals from

having a chance to compete with Visa.

     In this case, the complaint alleges plausibly that Visa’s

loyalty program prevented Visa’s customers from routing to PIN

networks even when PIN networks offered lower per-transaction

prices than Visa. See Compl. ¶¶ 80–83. In that way, this case is

distinguishable from cases where the defendants merely offered

discounts that encouraged volume shopping but did not prevent

customers from buying from or switching to rival suppliers when

those suppliers “offer[ed] better prices.” Cf., e.g., Concord

Orthopedic Appliances Inc. v. Tyco Health Care Grp. LP, 592 F.3d

991, 997 (9th Cir. 2010).

     The complaint also alleges plausibly that Visa

substantially foreclosed the relevant market from competition

from the other front of card networks. Exclusive dealing

arrangements of short duration and easy terminability tend not

to violate the antitrust laws. See CDC Techs., 186 F.3d at 81;

Omega Envt’l., Inc. v. Gilbarco, Inc., 127 F.3d 1157, 1163 (9th

Cir. 1997); Barry Wright Corp. v. ITT Grinnell Corp., 724 F.2d

Mktg. In-Store, Inc., 354 F.3d 661, 663 (7th Cir. 2004)

(recognizing that “competition for the contract is a vital form

of rivalry”). But long-term exclusive dealing arrangements,

especially those that are difficult to terminate, have the

potential to frustrate competition even from equally efficient

or more efficient suppliers. See ZF Meritor, 696 F.3d at 265,

277 (monopolist’s market-share contracts lasting at least five

years with every direct purchaser in the relevant market); Duke

Energy Carolinas, LLC v. NTE Carolinas II, LLC, 111 F.4th 337,

357 (4th Cir. 2024) (long-term contracts gave incumbent

monopolist the power to offer “blend-and-extend” discount that a

more efficient upstart could not match). In this case, not only

are Visa’s contracts alleged to be long-term contracts, Compl.

¶¶ 40, 99, 172, but moreover, the two-sidedness of the relevant

market amplifies their alleged exclusionary effect. See In re

Surescripts, 608 F. Supp. 3d. 645–47; FTC v. Surescripts, LLC,

424 F. Supp. 3d 92, 103–04 (D.D.C. 2020). Any particular

merchant and its acquirer cannot easily leave Visa altogether

for another front of card network because consumers will

continue to seek to use Visa debit cards at the merchant. See

Compl. ¶¶ 170–71. In other words, “losing [Visa] as a supplier

[is] not an option.” See ZF Meritor, 696 F.3d at 278. On the

other side, switching costs allegedly prevent issuers from

switching easily to other front of card networks like

Mastercard, and Reg II allegedly prevents rival networks from

using interchange fees to compensate regulated issuers’

switching costs. Compl. ¶¶ 52, 172. Taken together, the length

of Visa’s contracts, the market’s structure, and Visa’s dominant

position in the market suggest plausibly that even other front

of card networks are excluded from competition through

significant mechanisms other than price. See ZF Meritor, 696

F.3d at 277; Dentsply, 399 F.3d at 193–96; Dial Corp., 165 F.

Supp. 3d at 33.

     Indeed, the complaint alleges that there has been “paltry

penetration in the market by competitors over the years.” See

Dentsply, 399 F.3d at 194. This has allegedly transpired despite

Visa’s high rack rates and introduction of new fixed fees—market

                                   51
     Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 52 of 58



features that would normally invite competition and entry. See

Compl. ¶¶ 79, 87. But despite the efforts of Visa’s rivals to

compete on price and features, Visa’s exclusive dealing

contracts allegedly foreclosed competition before competition

could even take place. See id. ¶¶ 19, 104, 140–41.12 Not even

regulatory developments like Reg II and the 2023 Amendment have

spurred competition. See id. ¶¶ 95–96, 167, 175. This allegedly

has allowed Visa to maintain high operating margins in the

United States—an indication of anticompetitive effects. See id.

¶¶ 63–64; Google, 747 F. Supp. 3d at 178.

     Therefore, the complaint alleges plausibly that the PIN

networks’ inability to win transactions away from Visa despite

offering lower prices, and Visa’s lengthy and substantial

foreclosure of a two-sided market to other front of card

networks, taken together, indicate that Visa’s contracts may

have broken the competitive process itself. See MacDermid

Printing, 833 F.3d at 187 (noting that “the antitrust laws

protect competition, not competitors”). The possibility that

Visa’s pricing practices and superior network features may have

induced merchants and banks to enter into contracts with Visa is

“not irrelevant.” See ZF Meritor, 696 F.3d at 277. But the


12The complaint also alleges plausibly that Visa’s agreements not to
compete with competitors and potential competitors prevented entry and
thus aided in Visa’s alleged monopoly maintenance. See Google, 747 F.
Supp. 3d at 167–68. Visa’s alleged agreements not to compete are
addressed separately below.

question whether Visa earned exclusivity using volume discounts

and superior features, or whether Visa used its monopoly power

and other non-price mechanisms to coerce its way into its

dominant position, is one that is inappropriate for resolution

on a motion to dismiss. See Syngenta, 711 F. Supp. 3d at 579.

     Visa allegedly used its monopoly power to force long-term

exclusive dealing contracts on its customers. See Dentsply, 399

F.3d at 196; ZF Meritor, 696 F.3d at 283. And merchants and

banks alike were allegedly concerned that they would be unable

to meet consumer demand at Visa’s “punitive rack rates.” Compl.

¶¶ 12, 79. Thus, as alleged, Visa’s “exclusive agreements pose

precisely th[e] kind of threat” that the threat of supply

shortages did in ZF Meritor. See In re Remicade, 345 F. Supp. 3d

at 580; see also In re Surescripts, 608 F. Supp. 3d at 645–46

(recognizing that a dominant network can use loyalty discounts

to cement entry barriers and then “charge supracompetitive

prices” that “restrict the market’s overall number of

connections”).

     Visa relies on NicSand, Inc. v. 3M Co., where the court

applied the price-cost test and affirmed the dismissal of the

plaintiff’s complaint. 507 F.3d 442, 447 (6th Cir. 2007) (en

banc). But NicSand does not help Visa. In that case, NicSand

alleged that 3M had taken over NicSand’s monopoly in

do-it-yourself automotive sandpaper by offering large up-front

                                   53
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 54 of 58



payments to retailers in exchange for multi-year agreements to

provide exclusive shelf space. Id. at 447–49. But in that case:

the retailers demanded exclusivity, not the suppliers, id. at

451–53; NicSand and 3M competed with each other on terms of

competition that NicSand had established, id. at 453–58; and the

predominant mechanism of exclusion was price competition in the

form of up-front payments, see id. at 451–53. In this case, the

complaint alleges that: Visa coerced exclusivity on its

customers; Visa, as the dominant incumbent network, forced

rivals to compete on unfavorable terms; and although Visa’s

alleged loyalty scheme involved volume discounts, it also relied

on significant non-price mechanisms of exclusion. Indeed, the

NicSand court noted that antitrust liability might arise if 3M

used its retailer contracts “and its current market dominance to

establish unreasonable barriers to entry in the future.” Id. at

457. The complaint alleges that Visa did just that.

     In sum, the complaint alleges plausibly that Visa “use[d]

its power to break the competitive mechanism and deprive

customers of the ability to make a meaningful choice.” See ZF

Meritor, 696 F.3d at 285. Accordingly, Visa’s “characterization

of this case as a species of predatory pricing is not

persuasive.” See In re Surescripts, 608 F. Supp. 3d at 643; see

also Duke Energy, 111 F.4th at 354 (declining to apply “specific

conduct tests” where the plaintiff alleged “a complex or

                                   54
     Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 55 of 58



atypical exclusionary campaign”). Visa’s motion to dismiss based

on the price-cost test is therefore denied.

                     C. Agreements Not to Compete

     Visa’s final argument is that the terms of Visa’s current

contracts with Apple, PayPal, and Square disprove and defeat the

Government’s claim that Visa agreed with competitors and

potential competitors not to compete. Br. at 20–25; Rep. at 7–

10.13 But that argument ignores the complaint’s allegations about

Visa’s courses of dealing with Apple, PayPal, and Square. The

question whether Visa’s partner agreements unreasonably restrain

competition, contribute significantly to Visa’s alleged monopoly

maintenance, or both, is one that cannot be answered at the

pleadings stage.

     Visa’s partner contracts allegedly provide discounts and

incentives in a “quid pro quo” manner that “amount[s] to a

horizontal product market division” and “unreasonably

restrain[s] competition.” Compl. ¶¶ 112, 194.14 These contracts


13 Visa does not specify which claims for relief alleged in the
complaint this argument addresses. In any event, this argument raises
factual questions that are inappropriate for resolution on a motion to
dismiss. See Anderson News, L.L.C. v. Am. Media, Inc., 680 F.3d 162,
184 (2d Cir. 2012).
14 The complaint therefore does not make clear whether Visa’s partner

agreements are alleged to be illegal per se or whether their legality
should be determined under the rule of reason. See Compl. ¶¶ 112, 194.
“[N]aked restraints of trade” between horizontal competitors “with no
purpose except stifling competition” are illegal per se under Sherman
Act § 1. United States v. Topco Assocs., Inc., 405 U.S. 596, 608
(1972). But when the economic impact of an agreement is “not
immediately obvious,” the restraint should be judged under the rule of

                                    55
    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 56 of 58



allegedly give Visa the ability to charge partners high rack

rates and behavioral fees if the partner begins to compete

directly with Visa. Id. ¶¶ 113–37. Visa has allegedly used or

threatened to use that ability to punish partners in the past.

See id.

     Taken together, these allegations suggest plausibly that

Visa’s contracts with competitors and potential competitors “had

an actual adverse effect on competition as a whole in the

relevant market.” See Geneva Pharms., 386 F.3d at 506–07

(quoting Cap. Imaging Assocs., P.C. v. Mohawk Valley Med.

Assocs., Inc., 996 F.2d 537, 542 (2d Cir. 1993)); see also

Anderson News, 680 F.3d at 186, 189 (stressing the importance of

factual context in evaluating § 1 claims under Twombly); Starr

v. Sony BMC Music Ent., 592 F.3d 314, 323–24 (2d Cir. 2010)

(similar). The same allegations suggest plausibly that Visa’s

contracts work to suppress competition from fintech rivals and

to prevent entry by potential competitors, significantly aiding

Visa in its alleged monopoly maintenance. See Microsoft, 253

F.3d at 79; Google, 747 F. Supp. 3d at 167–68.




reason. See State Oil Co. v. Khan, 522 U.S. 3, 10 (1997); Leegin
Creative Leather Prods., Inc. v. PSKS, Inc., 551 U.S. 877, 886–87
(2007).
     For purposes of this motion, it is unnecessary to resolve that
ambiguity in the complaint. Visa’s argument fails for an independent
reason: in general, factual disputes cannot be resolved on a motion to
dismiss.

    Case 1:24-cv-07214-JGK   Document 89   Filed 06/23/25   Page 57 of 58



     Visa’s focus on its current contracts ignores “the facts

peculiar to [its] business, the history of the restraint, and

the reasons why it was imposed.” See Nat’l Soc. of Pro. Eng’rs

v. United States, 435 U.S. 679, 692 (1978). To evaluate properly

Visa’s contracts with partners, it may be necessary to consider

Visa’s courses of dealing with its partners. See id. Moreover,

the Government contends that, in submitting contracts with

partners, Visa failed to attach relevant documents that support

the complaint’s allegations. Opp. at 22. Disposing of this claim

at the pleadings stage therefore “risks depriving the parties of

a fair adjudication of the claims by examining an incomplete

record.” See Chambers, 282 F.3d at 155.

     Visa also argues that the challenged contractual clauses,

such as anti-steering provisions, are not anticompetitive. This

argument, however, overlooks the broader factual context alleged

in the complaint. See Anderson News, 680 F.3d at 186; Starr, 592

F.3d at 323–24. Namely, over the past decade, Visa allegedly

used financial incentives and termination threats to stymie

competition from partners. Compl. ¶¶ 120–37. Moreover, the

complaint alleges that Visa coerced partners into contractual

restraints that may plausibly bring about anticompetitive

effects, such as preferencing Visa in signup flow and default

settings. Id. ¶¶ 124, 132. Courts have recognized that such

default-setting practices may harm competition, especially in

                                   57
