US merchant acquiring is led by Fiserv (largest non-bank acquirer), FIS/Worldpay, JPMorgan Chase, Bank of America, and fintech-native players Stripe, Block (Square) and Toast. Acquirers settle on behalf of digital payment companies and ISOs. The market is consolidating (Global Payments-Worldpay), shifting to ISV/embedded distribution, and increasingly offering surcharging/dual-pricing. PCI DSS governs cardholder-data security across the acquiring chain; sponsor-bank relationships (e.g. Wells Fargo) remain the dominant access route for non-bank acquirers.
The ISV and embedded shift, combined with surcharging expansion, materially reshapes acquiring economics. Stripe is expected to exceed $1tn in US-sourced volume in 2026, and Toast ranks around 13th to 14th by US volume with roughly 24% year-on-year growth. The now-granted Stripe MALPB charter is a structural acquiring-access shift for non-bank acquirers, reducing reliance on sponsor banks for direct scheme access. This material is sourced from specialist intelligence and Tier-3 market research and is asserted at Assessed confidence.
Outlook
The acquiring landscape is established standing knowledge characterised by consolidation, the ISV/embedded distribution shift, and surcharging expansion. The structural development to watch is the maturation of the MALPB route as a means for non-bank acquirers to reduce sponsor-bank dependency. The trajectory is established. As with W6, heavy Tier-3 reliance on market data is a recognised gap, and primary-source confirmation beyond available SEC filings would strengthen confidence.
Merchant Acquiring & Risk
The US merchant-acquiring market is led by Fiserv, FIS/Worldpay, JPMorgan Chase and Bank of America on the bank/traditional-processor side, alongside fintech-native acquirers Stripe, Block (Square) and Toast. The market is actively consolidating, most visibly through the Global Payments-Worldpay combination, and distribution is shifting toward ISV and embedded-finance channels consistent with the broader industry-structure trend. A notable commercial development is the expansion of surcharging and dual-pricing: 61% of top acquiring providers now market surcharging or dual-pricing capability, up from 43% in 2023, a significant shift in how acquirers are positioning cost-recovery tools for merchants. Stripe is expected to exceed $1 trillion in US-sourced volume in 2026, and Toast — now roughly 13th-14th by US volume — grew approximately 24% year-on-year, indicating continued fintech-native share gains within the acquiring market. Stripe's now-granted MALPB charter is itself a structural acquiring-access shift, reducing the sponsor-bank dependency that otherwise defines non-bank acquirer market access.
Outlook
Continued consolidation around the Global Payments-Worldpay combination, further ISV/embedded-channel share gains, and the ongoing expansion of surcharging/dual-pricing adoption are the trends most likely to define US merchant acquiring through the remainder of 2026, with sponsor-bank dependency remaining the dominant access route for the large majority of non-bank acquirers not pursuing MALPB-style charters.
