Visa and Mastercard are both deploying stablecoin settlement infrastructure across their card networks, but their strategies have diverged sharply. Visa's stablecoin settlement volume hit a $20 billion annualized run rate in September 2026, up more than 15x year over year, with 160-plus stablecoin-linked card programs live on its network. Mastercard responded by acquiring BVNK, a London-based stablecoin infrastructure firm, for up to $1.8 billion in a deal that closed August 3, 2026 — making it the first major card network to own stablecoin settlement infrastructure outright.
The result is a structural split. Visa is building an open ecosystem that pairs VisaNet settlement data with onchain lending protocols to reduce working-capital costs for card issuers. Mastercard is vertically integrating, combining BVNK's enterprise plumbing with its Multi-Token Network and newly supported stablecoins to offer a closed-loop settlement alternative. Both networks are also validators on Circle's Arc blockchain, which launched its mainnet on September 16, 2026, with USDC as its native gas token. Together, these moves represent the largest reallocation of payments infrastructure toward blockchain rails in the history of the card industry.
Visa processed $14.2 trillion in payments volume in fiscal 2025, across 257.5 billion transactions. Mastercard processed $2.96 trillion in U.S. card purchase volume during the same period. Together, the two networks handle approximately 85% of global non-Chinese card payment volume.
Against that backdrop, stablecoin settlement remains small in absolute terms but is growing at a rate that demands attention:
| Metric | Visa | Mastercard | |--------|------|------------| | Stablecoin settlement run rate (Sept. 2026) | $20B annualized | Not disclosed | | YoY growth | 15x+ | N/A | | Stablecoin card programs | 160+ | Not disclosed | | Card program payment volume growth | ~200% YoY | N/A | | Infrastructure investment | $48M (Velocity Series A participation) | $1.8B (BVNK acquisition) | | Stablecoin infrastructure ownership | Minority stake (Velocity) | Full ownership (BVNK) |
The stablecoin market stood at $302.8 billion in total supply as of mid-September 2026. USDT held 60.6% market share at $183.4 billion. USDC followed at $74.2 billion. The total market contracted 0.8% over the prior 90 days, but institutional settlement activity accelerated in the same period.
Mastercard's strategy centers on owning the full stack. The $1.8 billion BVNK acquisition, announced March 17 and closed August 3, 2026, gave Mastercard direct control over stablecoin settlement infrastructure that was previously processing $30 billion annually for enterprise clients including Worldpay, Deel, and Flywire.
The deal included $300 million in performance-contingent payments and represented the largest acquisition of a crypto-native payments company by a traditional financial institution. Notably, Visa had previously held a strategic stake in BVNK — acquired in May 2025 at a roughly $750 million valuation — and had entered a partnership with the firm in January 2026 to enable stablecoin payments on Visa Direct. Mastercard's acquisition terminated that relationship.
Beyond BVNK, Mastercard expanded its settlement framework in June 2026 to support regulated U.S. dollar stablecoins including USDC, PYUSD, USDP, RLUSD, USDG, and SoFiUSD. The framework introduced new settlement windows: intraday, weekend, and holiday cycles across Ethereum, Solana, Polygon, Base, Arbitrum, and XRPL.
On September 22, SoFi Bank — the first nationally chartered, FDIC-insured U.S. bank to issue a stablecoin — went live settling its entire $25 billion card program through SoFiUSD on Mastercard's network. Roughly 70% of SoFiUSD's $332 million in circulation runs on Solana; 30% on Ethereum. Reserves are backed 85% by short-term U.S. Treasury bills and 15% by cash at FDIC-insured institutions.
Early adopters on Mastercard's stablecoin settlement rails include ARQ (formerly DolarApp), CBW Bank, Cross River, Lead Bank, and Nuvei, with initial deployments in the U.S. and Latin America.
Visa took a different path. Rather than acquiring infrastructure, it is opening VisaNet's settlement data to third-party onchain lenders, creating a composable layer between traditional payment flows and DeFi-style credit markets.
On September 8, 2026, Visa disclosed that its stablecoin settlement volume had surpassed a $20 billion annualized run rate. The company simultaneously outlined a model in which authorized blockchain-based lenders can review VisaNet settlement data alongside onchain transaction records. With card-program authorization, this combined dataset supports automated credit assessment and settlement financing.
Credit Coop, a DeFi lending protocol working with Visa, built a stablecoin-denominated revolving credit facility secured by settlement receivables. The facility uses daily Visa settlement files and Credit Coop's Spigot smart contract to size funding and automate repayments. According to Visa, borrowing costs for participating programs have declined by as much as 30% as more lenders have underwritten these facilities. Lenders including Credit Coop and Rain have financed a combined $4.5 billion in stablecoin-linked card settlement without a single default.
Visa's production settlement runs primarily on Solana, working with Cross River Bank and Lead Bank on a seven-day settlement cycle. More than 160 stablecoin-linked card programs operate on Visa's network, with payment volume on those programs growing nearly 200% year over year.
The BVNK acquisition created a strategic gap for Visa. On August 18, 2026 — 15 days after Mastercard closed the deal — Visa issued a request for proposal seeking a new stablecoin settlement and OTC partner. The RFP specified requirements for cryptocurrency-exchange licenses in the U.S., Canada, the U.K., and Singapore.
By September 10, Visa had its answer. Velocity, a stablecoin-powered enterprise payments and treasury platform, extended its Series A round to $48 million at a $200 million valuation, with Visa Ventures as a new backer. Circle and Ripple also participated. On September 9, MVB Financial partnered with Velocity to join a Visa Direct pilot supporting stablecoin-enabled funding and settlement for push-to-card payouts.
The speed of the pivot — from RFP to investment to pilot in under four weeks — indicates Visa had identified Velocity as a potential replacement before the BVNK deal closed. Velocity's valuation ($200 million) compares with BVNK's acquisition price ($1.8 billion), a 9x gap that reflects either the difference in maturity between the two firms or that Mastercard paid a strategic premium to deny Visa a partner.
Circle's Arc blockchain launched its mainnet on September 16, 2026, with both Visa and Mastercard among its founding validators. The validator cohort also includes BlackRock, DTCC, Galaxy, Global Payments, ICE, MoneyGram, SBI Group, Standard Chartered, and Sumitomo Corporation.
Arc is a Layer 1 network purpose-built for financial applications. It runs the Ethereum Virtual Machine for smart-contract compatibility but uses USDC as its native gas token instead of a separate asset, making transaction costs predictable for institutional users. The network uses Malachite consensus for sub-second finality. More than 100 applications went live at launch, including Aave V4, Morpho, and Uniswap.
The presence of both Visa and Mastercard as validators on the same chain introduces a structural oddity: two competitors validating the same settlement layer that could eventually disintermediate their own networks. The economics suggest this is a hedging strategy. If stablecoin settlement migrates to purpose-built chains like Arc, both networks want validator-level visibility into that activity.
The regulatory environment is accelerating this transition. The GENIUS Act, signed in 2025, established a federal framework for payment stablecoins. As of September 2026, the Federal Reserve has proposed rules for bank subsidiaries to apply for stablecoin issuance permission, with comments due by October 19, 2026. The OCC issued its own proposed rulemaking. The CFTC, on September 24, updated its FAQs to permit futures commission merchants and derivatives clearing organizations to invest customer funds in tokenized forms of permitted investments.
In Europe, ESMA announced on September 23 that AI and tokenization will become a Union Strategic Supervisory Priority starting in 2027. Of 847 AI use cases reported by EU securities firms, 87% were internal; only 3% involved investment services — a gap the regulator aims to close.
The value distribution question for card networks is straightforward: stablecoin settlement compresses the time between transaction and merchant receipt from 1-2 business days to seconds. That eliminates float income for intermediaries. Visa's answer is to capture value through data monetization and lending facilitation. Mastercard's answer is to own the infrastructure and extract margin at the protocol level. Both approaches face the same structural pressure: the underlying settlement layer is becoming a commodity.
At $20 billion annualized, Visa's stablecoin settlement represents 0.14% of its $14.2 trillion in annual payments volume. The percentage is small. The growth rate — 15x year over year — is not.
Visa and Mastercard are no longer experimenting with stablecoins. They are deploying production infrastructure, hiring protocol engineers, and committing billions in capital to own or partner with the plumbing. The strategies differ — Visa is opening its data layer to DeFi lenders, Mastercard is buying the pipes — but the destination is the same: a card network that settles in stablecoins rather than through correspondent banking. At current growth rates, Visa's stablecoin settlement would represent over 2% of its annual payments volume within two years. The percentage at which stablecoin settlement stops being an experiment and starts affecting interchange economics remains an open question. Neither network appears willing to wait for the answer.
