Mastercard is a payments network and technology company, not a card-issuing bank. It connects account holders, financial institutions, merchants and acquirers; authorizes, clears and settles transactions; licenses its brands; and sells security, data, authentication, processing and account-to-account payment services. Banks and other issuers generally extend credit, set cardholder fees and manage customer relationships.
That distinction explains both Mastercard’s economics and its accountability. The company says it does not receive interchange, the fee generally collected from an acquirer and paid to an issuer. But Mastercard sets default interchange rates when other terms have not been agreed, administers their collection and remittance, and establishes network rules. Merchant acceptance costs, routing choice and access to network technology have therefore made Mastercard a recurring target of litigation and regulatory intervention even though interchange itself is not booked as Mastercard revenue.
How the four-party network works
A typical transaction involves four main participants: an account holder, the issuer that provides the payment credential, a merchant and the merchant’s acquirer. When a payment is presented, Mastercard can route an authorization request to the issuer, exchange clearing information after approval and facilitate settlement between financial institutions. The acquirer separately pays the merchant after deducting the merchant discount.
Mastercard does not switch every transaction carrying its brands. Its 2024 annual report said it switched approximately 70% of Mastercard- and Maestro-branded transactions, including nearly all cross-border transactions. It guarantees settlement from issuers to acquirers for many transactions, creating settlement exposure, but does not guarantee an acquirer’s payment to a merchant or the availability of unused prepaid balances.
The network’s scale is global. Mastercard said it enabled transactions in more than 150 currencies and more than 220 countries and territories. In 2024, cards carrying its brands generated $9.8 trillion in gross dollar volume, and Mastercard switched 159.4 billion transactions. The company also began processing domestic transactions in China through a joint venture during the year, adding local processing to its existing cross-border acceptance there.
Where Mastercard’s revenue comes from
Mastercard divides net revenue, after rebates and incentives, into two businesses. Payment-network revenue comes mainly from assessments tied to domestic and cross-border gross dollar volume, card counts, transaction switching and other network services. Value-added services and solutions include security, consumer acquisition and engagement, business and market insights, digital and authentication tools, processing and gateways, open banking, and batch or real-time account-based payments.
For 2024, Mastercard reported $28.167 billion of net revenue and $12.874 billion of net income. Payment-network revenue was $17.335 billion, while value-added services and solutions contributed $10.832 billion. The geographic mix was also broad: $12.375 billion came from the Americas and $15.792 billion from Asia Pacific, Europe, the Middle East and Africa. Mastercard said about 70% of total revenue was generated from activities outside the United States.
Growth continued in the first quarter of 2025. Mastercard reported $7.250 billion of net revenue, up from $6.348 billion a year earlier. Payment-network revenue was $4.432 billion and value-added services and solutions revenue was $2.818 billion. Those figures show why Mastercard increasingly competes as a security and software provider as well as a card network.
Customer incentives are an important counterweight to network scale. Banks, fintechs, merchants and other partners can support more than one network, so Mastercard uses rebates and pricing concessions to win portfolios and encourage volume. The company warns that greater incentive demands can require additional transaction or services growth simply to preserve the economics of a customer agreement.
Products beyond the plastic card
The core franchise covers consumer credit, debit and prepaid payments as well as commercial cards. A Mastercard credential can be presented on a physical card, through contactless hardware, inside a mobile wallet or at an ecommerce checkout. The network remains relevant when the form factor disappears because the underlying credential, token, authorization and settlement messages can still use Mastercard infrastructure.
Tokenization is central to that strategy. Mastercard’s Digital Enablement Service replaces a card’s primary account number with a restricted digital token for eligible devices, merchants or transaction contexts. The company said about 30% of Mastercard transactions were tokenized in 2024, while contactless represented about 70% of in-person purchase transactions on Mastercard-branded cards. Click to Pay provides a network-backed online checkout, and Digital First supports issuance and management of credentials before or without a physical card.
Mastercard Send targets person-to-person transfers, disbursements and other money movement. Vocalink gives Mastercard infrastructure for automated clearing house and real-time account-to-account systems. Open-banking products connect permissioned bank-account data and payment initiation, while gateway and processing services can serve merchants and financial institutions around transactions that do not necessarily run over the Mastercard card network.
This broader portfolio gives the company several ways to participate as payments shift toward instant bank transfers and digital wallets. It also creates a strategic tension: an account-to-account rail can displace a card transaction, but Mastercard may still sell the connectivity, fraud controls or analytics around that payment.
Competitive position
Mastercard’s closest global rival is Visa. It also competes with American Express, Discover, JCB and UnionPay; domestic card schemes and debit networks; cash and checks; processors; wallets; buy-now-pay-later providers; and bank-transfer systems. Financial institutions can issue both Mastercard- and Visa-branded products, making major portfolios contestable even when consumers see both brands as nearly universal.
The company’s principal advantage is a two-sided network effect. Broad acceptance makes the credential more useful to issuers and account holders, while a large base of active credentials makes acceptance attractive to merchants and acquirers. Scale also supplies data and distribution for fraud, identity and consulting services. Cross-border reach is particularly difficult for a domestic alternative to reproduce.
That advantage is not absolute. Local routing mandates and processing rules can strengthen domestic networks. Instant-payment systems can bypass card rails. Large banks, merchants and technology platforms can bargain for lower prices or direct traffic elsewhere. Mastercard itself identifies regulation, customer incentives, cyber incidents, service disruption, settlement exposure and competition from existing and new payment methods as material risks.
Antitrust enforcement and merchant-cost disputes
Regulators have intervened when Mastercard’s rules were judged to restrict choice. In January 2019, the European Commission fined Mastercard €570.6 million for rules that limited merchants’ ability to obtain card-acquiring services across borders within the European Economic Area. The Commission said the restrictions insulated banks from cross-border competition and prevented retailers from benefiting from lower fees elsewhere in the single market. Mastercard received a reduction for cooperating. The decision concerned past conduct and should not be read as a finding that every Mastercard fee was unlawful.
In the United States, the Federal Trade Commission alleged in December 2022 that Mastercard used its ecommerce tokenization policies to inhibit competing debit networks. U.S. law generally requires at least two unaffiliated networks to be available for routing debit transactions, giving merchants a choice that can affect price and fraud controls. The FTC said Mastercard’s policy prevented competing networks from obtaining the account information needed to route some card-not-present transactions after Mastercard tokens had replaced card numbers.
Under the FTC’s consent order, finalized in 2023, Mastercard was required to provide competing networks with the customer account information needed to convert tokens for routing and barred from taking action designed to prevent competitors from supplying their own payment-token services. A consent order resolves the agency’s allegations without a litigated finding that every alleged violation occurred, but the remedy is material: security technology cannot be used as a gate that nullifies statutory routing choice.
Merchant litigation remains another structural pressure. Mastercard’s 2024 filing described long-running U.S. claims accusing Mastercard, Visa and participating banks of conspiring over interchange and network rules. A damages-class settlement became final in 2023, and Mastercard said settlements covering that class and many opt-out merchants represented more than 90% of its U.S. interchange volume. But rules-related litigation and individual opt-out claims continued. The company recorded a $584 million litigation provision in 2024, primarily tied to a U.K. consumer class-action settlement provision, U.K. merchant settlements and revised estimates for U.S. opt-out merchants.
These disputes matter to smaller merchants because network economics are distributed unevenly. Issuers receive interchange and may use it to fund rewards or account services; acquirers and processors add their own charges; and merchants pay the combined acceptance cost. Mastercard does not receive the interchange amount, but its default schedules, network fees, rules and technology affect the system in which those costs are set and routed. The company warns that interchange set too high can cause merchants to reject or steer away from its products, while rates set too low can reduce issuer promotion and cardholder benefits.
What payments professionals should watch
Mastercard’s durable strength is not the piece of plastic. It is the combination of global acceptance, transaction routing, settlement assurance, credential technology and a growing services layer. The company can earn from payment volume and switching while selling fraud, identity, data and account-to-account capabilities around the flow.
The key constraint is that the same integration that creates reliability can also concentrate control. Regulators and merchants will continue to test whether tokenization, routing rules, interchange defaults and commercial agreements preserve genuine choice or protect incumbent economics. Mastercard’s opportunity is to remain useful across cards, instant payments and digital credentials; its risk is that technology presented as security or convenience becomes a mechanism for blocking lower-cost routes or entrenching market power.
