Merchant Acquiring Market Size & Share Analysis - Growth Trends and Forecast (2026 - 2031)

Global Merchant Acquiring Market Trends and Insights

E-Commerce and Omnichannel Acceptance Expansion

The merchant acquiring market benefits as merchants combine store, online, and mobile payment acceptance within one operating model. A fragmented setup can create separate settlement processes, incomplete customer records, and more difficult payment reconciliation for merchants that sell through several channels. Visa reported that 43% of surveyed merchants accepted real-time payments in 2026, and 83% of those merchants saw a definite increase in use during the preceding year.^{[1]Visa, “2026 Global Ecommerce Payments and Fraud Report,” Visa Acceptance, visaacceptance.com} The same need for unified acceptance increases demand for processors that can manage several payment methods through one back-end system. This puts pressure on providers that still treat online and in-person payments as separate products. It also gives established acquirers an opportunity to retain merchants when they can offer consistent settlement, reporting, and support across channels.

Embedded Payments Through Vertical Software and Marketplaces

Vertical software platforms are becoming a major route to merchants for the merchant acquiring market. These platforms can place payment acceptance inside scheduling, invoicing, dispatch, or commerce tools that merchants already use each day. Fiserv stated in its 2026 ISV playbook that embedded working capital, disbursements, and fraud defense can help platforms deepen merchant adoption beyond stand-alone payment acceptance.^{[2]Fiserv, “2026 ISV Playbook: Three Imperatives,” Fiserv, fiserv.com} The model can reduce the need for a merchant to choose a processor separately from its operating software. It can also have more control over pricing and customer access toward the software platform. Acquirers that supply infrastructure without a clear software distribution strategy may face greater pressure on their share of merchant payment economics.

Real-Time Account-to-Account Rails and Pay-by-Bank

Real-time account-to-account payment rails create a direct cost and product challenge for the merchant acquiring market. Merchants can use pay-by-bank options to initiate payments from a customer account instead of relying solely on card rails. JPMorgan Chase offers Pay by Bank capabilities across the United States, the United Kingdom, and the European Union through an open banking API, including real-time pay-ins and closed-loop refunds. These options can matter for merchants with high payment volumes and a strong reason to manage acceptance costs. They can also create a new service opportunity for acquirers that add account-to-account initiation, reconciliation, and refund functions. Providers that do not support these rails may lose relevance where merchants want a broader mix of payment choices.

Tokenization and Network-Token Authorization Gains

Network tokenization supports card acceptance by replacing static account details with payment credentials that can be updated and managed more securely. Visa reported a 4.6% authorization-rate uplift for card-not-present transactions using network tokens rather than raw primary account numbers.^{[3]Visa, “A Deep Dive Into Tokenized Transactions,” Visa, corporate.visa.com} Mastercard also reported a 2.1% average authorization improvement, while Checkout.com data cited by Mastercard showed a 10.3 percentage-point authorization-rate improvement for merchants using network tokens. These gains can be particularly relevant for recurring payments and stored credentials, where expired cards and soft declines can disrupt collections. The merchant acquiring industry can use tokenization to position payment acceptance as a revenue-protection service rather than only a security feature. Better authorization results can strengthen the value of acquirer relationships with merchants that have large digital payment volumes.

Interchange and Scheme-Fee Volatility

Interchange and scheme-fee volatility creates uncertainty for acquirers that price merchant services around stable blended rates. In June 2026, a U.S. federal judge approved a USD 38 billion Visa and Mastercard swipe-fee settlement that set a maximum standard consumer rate of 1.25% for 8 years and reduced average fees by 0.1 percentage point for 5 years. The UK Payments System Regulator also retained authority to impose caps on United Kingdom-European Economic Area cross-border interchange fees after a January 2026 High Court decision. These developments can change fee structures across merchant portfolios and reduce the predictability of pass-through revenue. They increase the need for clear merchant communications and flexible pricing controls. The merchant acquiring market also faces added complexity when state, national, and cross-border rules affect the same merchant relationship.

Card-Not-Present Fraud and Chargeback Liability

Card-not-present fraud and chargeback liability can reduce profitability and make onboarding more restrictive for higher-risk merchants. Visa consolidated fraud and dispute monitoring under its Acquirer Monitoring Program in April 2025, and its merchant excessive-ratio threshold became 1.5% on April 1, 2026.^{[4]Visa, “Visa Acquirer Monitoring Program,” Visa, corporate.visa.com} The tighter threshold increases the importance of fraud prevention, dispute management, and merchant education. A merchant that remains above applicable thresholds can face more serious consequences for card acceptance. Acquirers therefore need fraud tools that support both transaction screening and operational action after a dispute occurs. This shifts fraud capability from a compliance requirement to a central part of merchant retention and portfolio management.

Segment Analysis

By Payment Method: Credit Cards Retain Scale While BNPL Gains Use

Credit cards held 34.25% of the merchant acquiring market share in 2025, making them the largest payment method segment. Their position reflects established acceptance networks, consumer loyalty programs, and broad merchant familiarity with card-based processing. Debit cards, digital wallets, e-wallets, bank transfers, and account-to-account payments remain important alternatives across regional payment systems. BNPL is projected to record a 10.20% CAGR through 2031, making it the fastest-growing payment method in the merchant acquiring market. The Federal Reserve reported that BNPL providers originated close to USD 160 billion in consumer credit products during 2025, with pay-in-4 plans representing close to half of issuance and more than 60% of total issuance carrying a 0% annual percentage rate.

BNPL adds a payment option for consumers who want scheduled installments rather than revolving credit, and it can support diverse checkout preferences. Klarna reported that it surpassed 1 million merchants globally in March 2026 after adding 285,000 merchants during 2025. The model is also being used beyond a one-time checkout payment, including recurring expenses and subscription renewals. That wider use can deepen its role in merchant cash-flow planning and customer retention. Acquirers need to support relevant payment methods without creating separate experiences for settlement, reporting, and refunds.

By Merchant Size: Large Enterprises Lead While SMEs Expand Faster

Large enterprises commanded 56.12% of the merchant acquiring market share in 2025. Their substantial transaction volumes, international operations, and complex acceptance need support customized acquiring arrangements. These merchants often require detailed reporting, multi-currency settlement, and sophisticated controls for risk and routing. SMEs are projected to record a 9.65% CAGR through 2031, supported by embedded acquiring within software they use to run their businesses. The merchant acquiring market size for SMEs is supported by tools that bring payment acceptance into invoicing, scheduling, point-of-sale, and online commerce workflows.

Software platforms can reduce the administrative burden of selecting a separate acquirer and integrating payment functions after onboarding. Fiserv stated that embedded financial tools can support more durable merchant relationships than payments alone. Working capital, fraud controls, and disbursements can be useful additions for smaller merchants with uneven cash flow or limited staff. The model also changes the commercial relationship because a software provider may seek a greater share of payment economics as it scales. Acquirers must provide reliable infrastructure while preserving a meaningful role in the merchant relationship.

By Channel: POS Solutions Lead While mPOS and SoftPOS Accelerate

POS solutions accounted for 44.71% of the merchant acquiring market size in 2025. They remain important for merchants that need durable in-person payment acceptance in retail, food service, and hospitality locations. Payment gateways serve a large share of digital commerce activity and support online checkout, recurring billing, and payment routing. mPOS and SoftPOS are projected to record a 9.91% CAGR through 2031, making them the fastest-growing channel. This shift reduces the need for separate payment hardware in some merchant settings and can support mobile sellers, delivery staff, temporary events, and smaller businesses.

SoftPOS can turn a compatible consumer device into an acceptance point when the required security and software conditions are met. Visa reported that Tap to Phone adoption was increasing by an average of 200% year over year globally. This channel can help processors place payment services closer to merchant workflows without a lengthy hardware deployment, and it can strengthen software-led distribution. Acquirers need to maintain dependable support, security, and transaction visibility as payment devices become more distributed. Dedicated terminals remain relevant for merchants with specialized checkout needs, but SoftPOS expands the settings where contactless payments can be accepted.

By End-User Industry: Retail and E-Commerce Lead While Logistics Advance

Retail and e-commerce held 34.51% of the merchant acquiring market share in 2025. This segment uses payment systems across store checkout, online sales, loyalty programs, returns, and delivery channels. Its size makes it a central setting for omnichannel acceptance and the adoption of digital wallets and BNPL options. Transportation and logistics are projected to record a 10.40% CAGR through 2031 as freight platforms embed payment, settlement, and working-capital functions into operational workflows. This can improve payment visibility for carriers and other companies that manage complex business-to-business transactions.

Visa and Airwallex announced a July 2026 collaboration to develop embedded finance solutions for freight and shipping platforms, addressing cross-border payments, working capital, and settlement processes. Healthcare is another specialized vertical with distinct payment needs because it connects patients, providers, claims, and revenue-cycle operations. Waystar reported that its platform processed more than 7.5 billion healthcare payment transactions annually and handled USD 2.4 trillion in gross claims. These examples show why vertical knowledge can matter as much as processing scale. Providers that understand workflow, documentation, and settlement requirements can build a more relevant offering for each end-user industry.

Geography Analysis

North America held 34.43% of the merchant acquiring market share in 2025. The region has a mature card ecosystem and significant payment volumes, but United States payment network volume expansion has moderated. This moderation increases competition for existing merchant relationships. Stripe entered the U.S. top five in 2026 with more than USD 900 billion in volume and 45% year-over-year expansion, according to the input. Checkout.com received approval for a Merchant Acquirer Limited Purpose Bank charter from the Georgia Department of Banking and Finance in January 2026, allowing it to pursue direct acquiring without a third-party sponsor bank.

Asia-Pacific is projected to record a 10.54% CAGR through 2031, the fastest rate among the geographic segments. China, India, and Southeast Asia are driving payment volumes through widespread adoption of digital wallets and government-backed real-time payment rails, while Australia and Japan represent mature markets with strong contactless payment penetration. The merchant acquiring market across Asia-Pacific increasingly depends on the ability to support diverse wallet ecosystems, real-time payment infrastructure, and alternative payment methods alongside traditional card acceptance. This shift is creating opportunities for acquirers that can provide seamless omnichannel acceptance, localized payment capabilities, and scalable infrastructure across both developed and rapidly digitizing markets.

Europe combines mature cashless markets with countries that continue to convert cash payments to cards and digital methods. The United Kingdom and Nordic countries have intense competition in core acquiring, while France and Spain offer room for payment-volume expansion through e-commerce and cash-to-card conversion. In South America, Brazil’s Pix system is changing acceptance economics, and PayPal added Pix support for SMEs in April 2026. The Middle East and Africa combine regulatory modernization with local requirements, while South Africa and Nigeria provide longer-term opportunities shaped by digital adoption and data rules.
