"The next phase of stablecoin adoption is about real-world utility, especially in settlement, where timing and liquidity matter most." — Raj Dhamodharan, Executive Vice President of Blockchain and Digital Assets, Mastercard
Mastercard on June 3, 2026 opened its settlement infrastructure to six regulated stablecoins across eight blockchain networks, matching and in some areas surpassing Visa's existing onchain settlement program. The announcement, paired with Mastercard's pending $1.8 billion acquisition of stablecoin infrastructure firm BVNK and a New York BitLicense secured on May 27, marks the most aggressive stablecoin infrastructure buildout by a legacy card network to date. Visa, which launched U.S. USDC settlement in 2025 and expanded to nine blockchains in 2026, now operates a $7 billion annualized stablecoin settlement run rate.
The two networks collectively processed $24.8 trillion in card payment volume in fiscal year 2025. The stablecoin settlement layer they are building sits atop a broader market: stablecoins processed an estimated $33 trillion in 2025 transfer volume, exceeding both card networks' combined throughput. Both Visa and Mastercard are now positioning stablecoin rails not as alternatives to their card networks but as complementary settlement infrastructure — a strategic response to keep payment flows within their ecosystems rather than lose them to native crypto rails.
Mastercard's settlement expansion covers six stablecoins: Circle's USDC, Paxos-issued PYUSD (PayPal's stablecoin), USDG, USDP, Ripple's RLUSD, and SoFi's SoFiUSD. These are enabled across eight blockchain networks: Ethereum, Solana, Polygon, Base, Arbitrum, Canton, Tempo, and XRPL.
The framework introduces four settlement modes beyond the existing batched fiat model:
Five financial institutions are among the first to adopt the new settlement options: ARQ (formerly DolarApp), CBW Bank, Cross River, Lead Bank, and Nuvei. Initial geographic coverage spans the United States and Latin America, with expansion planned through the remainder of 2026.
Mastercard processed $10.6 trillion in payments volume during 2025 across more than 175 billion transactions. Q1 2026 gross dollar volume reached $2.7 trillion, reflecting 7% growth on a local currency basis. The stablecoin settlement layer will operate alongside this existing fiat infrastructure.
The announcement followed Mastercard's May 27 acquisition of a New York BitLicense from NYDFS — one of approximately 40 such licenses issued since the program launched in 2015, and one of only three granted in 2026. The license permits Mastercard to handle digital currencies, stablecoins, tokenized deposits, and onchain settlement flows within New York's regulatory jurisdiction. Mastercard Chief Product Officer Jorn Lambert stated the approval "underscores our focus on aligning innovation with regulatory expectations of high levels of security, compliance, and risk management."
Visa entered stablecoin settlement before Mastercard. The network launched USDC settlement on Ethereum in a pilot with Crypto.com in 2021, expanded to Solana in subsequent years, and formally launched U.S. stablecoin settlement in 2025 with Cross River Bank and Lead Bank as initial partners.
As of April 2026, Visa's stablecoin settlement program reached a $7 billion annualized run rate, up 50% from the prior quarter and up from $4.5 billion in January 2026. Stablecoin-linked card spend hit $3.5 billion annualized in Q4 2025, representing approximately 19% of total crypto card volume. Visa supports more than 130 stablecoin-linked card programs in over 40 countries.
Visa has expanded to nine supported blockchains: Ethereum, Solana, Avalanche, Stellar, Base, Polygon, Canton Network, Arc, and Tempo. Notably, Visa is a design partner for Circle's Arc, a new Layer 1 blockchain currently in public testnet, and plans to operate a validator node once the network goes live.
Visa processed $14.2 trillion in total payments volume during fiscal year 2025 across 257.5 billion processed transactions. Q2 2026 processed transactions reached 66.1 billion, a 9% year-over-year increase.
| Dimension | Visa | Mastercard | |---|---|---| | Stablecoins supported | USDC (primary) | USDC, PYUSD, USDG, USDP, RLUSD, SoFiUSD | | Blockchain networks | 9 (Ethereum, Solana, Avalanche, Stellar, Base, Polygon, Canton, Arc, Tempo) | 8 (Ethereum, Solana, Polygon, Base, Arbitrum, Canton, Tempo, XRPL) | | Stablecoin settlement run rate | $7B annualized (Apr 2026) | Not yet disclosed | | FY2025 total payments volume | $14.2T | $10.6T | | Stablecoin card programs | 130+ in 40+ countries | Not yet disclosed | | Key acquisition | Design partner for Circle's Arc L1 | BVNK ($1.8B, pending) | | Regulatory licenses | N/A (via banking partners) | NY BitLicense (May 2026) | | U.S. launch partners | Cross River, Lead Bank | Cross River, Lead Bank, CBW Bank, ARQ, Nuvei |
Both networks share Cross River and Lead Bank as launch partners. The overlap indicates these mid-tier banks have positioned themselves as the go-to regulated intermediaries for card network stablecoin flows. Neither JPMorgan Chase, Bank of America, nor any top-10 U.S. bank by assets has announced participation in either program.
Mastercard's broader stablecoin roster — six tokens versus Visa's primary reliance on USDC — reflects a multi-issuer strategy. By supporting PayPal's PYUSD, Ripple's RLUSD, and SoFi's SoFiUSD alongside Circle's USDC, Mastercard is hedging against single-issuer concentration risk and courting a wider set of fintech partners.
The card networks' stablecoin infrastructure strategies are underwritten by two of the largest acquisitions in stablecoin history.
Stripe acquired Bridge for $1.1 billion (announced October 2024, closed February 2025). Bridge provides stablecoin orchestration across 130+ countries, enabling cross-border payments, treasury management, and fiat-to-stablecoin conversion. Under Stripe, Bridge saw transaction volume quadruple in 2025. Stripe shipped five major stablecoin products in twelve months after the acquisition, including expanded market coverage, subscription payments, Visa card partnerships, and a custom stablecoin issuance platform. Stripe's Tempo, a payments-focused Layer 1, launched on mainnet in March 2026 with partnerships spanning Visa, Nubank, and Shopify.
Mastercard agreed to acquire BVNK for up to $1.8 billion (announced March 2026, expected to close by year-end). BVNK provides enterprise stablecoin payment infrastructure across 130+ countries, enabling sending and receiving payments on all major blockchain networks. The deal includes $300 million in contingent payments. BVNK had previously been courted by Coinbase at approximately $2 billion before negotiations ended around November 2025.
The BVNK acquisition eclipses Stripe-Bridge as the largest stablecoin infrastructure deal. The escalating price tags — $1.1 billion in October 2024, $1.8 billion in March 2026 — reflect rapidly rising valuations for stablecoin plumbing companies as institutional demand grows.
The card networks are moving into stablecoin settlement against a backdrop of rapid market expansion:
The regulatory environment has converged in parallel. Seven major economies — the U.S., EU, UK, Singapore, Hong Kong, UAE, and Japan — now mandate full reserve backing, licensed issuers, and guaranteed redemption rights for stablecoins. In the U.S., the GENIUS Act's implementing rules require comment by June 9, 2026, with the July 18 compliance deadline approaching. FinCEN and OFAC jointly issued proposed AML/sanctions rules for stablecoin issuers in April 2026.
According to industry estimates, approximately 90% of financial institutions are already using or piloting stablecoins, and around 60% of stablecoin flows are now B2B — corporates using dollar tokens for cross-border treasury, supplier payments, and procurement.
The economic question for both card networks is whether stablecoin settlement preserves or erodes their fee structures. Traditional card settlement involves interchange fees (1.5–3.5% for credit, 0.5–1% for debit), network assessment fees, and processing charges. Stablecoin settlement on public blockchains carries gas costs of fractions of a cent on L2s and low single-digit cents on L1s.
The card networks are not replacing their fee-generating card authorization layer with stablecoins. Instead, they are replacing the back-end settlement layer — the interbank funds transfer that happens after a card transaction is authorized. This preserves the revenue-generating portions of the transaction (authorization, fraud screening, chargeback management, merchant acquiring) while potentially reducing settlement costs and latency.
The risk is disintermediation. If merchants and consumers become comfortable transacting directly in stablecoins — bypassing the card networks' authorization layer entirely — the settlement efficiency of stablecoins becomes a competitive threat rather than a complementary tool. Stablecoins already process more dollar volume than both card networks combined, though the comparison is imperfect: much of stablecoin volume consists of DeFi transfers and exchange settlement rather than consumer-merchant transactions.
For now, both networks are betting that their trust infrastructure, fraud protection, dispute resolution, and merchant acceptance networks constitute a durable moat — one that stablecoin rails alone cannot replicate. The settlement layer upgrade positions them to capture flows that might otherwise migrate to native crypto payment processors.
The Visa-Mastercard stablecoin settlement race is now a two-front competition: who can support more tokens and chains (Mastercard currently leads) and who can drive more actual settlement volume (Visa currently leads with disclosed data). Both are integrating stablecoins into the settlement layer while preserving the fee-generating authorization and network layers that produce their revenue.
The strategic logic is defensive as much as offensive. Stablecoins already move more value than both card networks combined. If native stablecoin payments gain merchant acceptance without card network intermediation, the networks face revenue compression on the $24.8 trillion in annual card volume they currently process. By building stablecoin settlement into their existing infrastructure, Visa and Mastercard are attempting to make onchain settlement a feature of their networks rather than a competitor to them.
The next twelve months will determine whether stablecoin settlement remains a rounding error on legacy card volume or becomes a meaningful portion of daily flows. The BVNK acquisition close, Visa's Arc validator node launch, and the GENIUS Act implementation timeline will serve as the key milestones.
