Visa Stablecoin Platform (VSP): The Onramp Connecting Banks, Fintechs, and Crypto to 200 Million Merchants

The connection point is vital: VSP sits between a client's onchain stablecoin operations and Visa's network of roughly 200 million merchants and 15,000+ financial institutions. Visa settles approximately $15 trillion in payments annually across this network. VSP is the onramp letting banks and fintechs route stablecoin liquidity into that existing acceptance footprint.

Current Scale of Visa's Stablecoin Operations

Stablecoin settlement run rate: Visa's stablecoin settlement pilot reached a $7 billion annualized run rate as of April 2026, up 50% quarter-over-quarter. This spans nine blockchains after Visa added Arc, Base, Canton, Polygon, and Tempo to its existing support on Avalanche, Ethereum, Solana, and Stellar.

Stablecoin-linked card programs: Visa operates more than 130 programs across over 50 countries—arrangements between Visa and card issuers enabling spending of stablecoins or crypto at merchants worldwide. In 2025 alone, these cards processed approximately $5.2 billion in volume, a 319% year-over-year increase (though still just 0.04% of Visa's $14.2 trillion total global volume). Visa expects the number of stablecoin card programs to roughly double in 2026 based on the active pipeline of issuers and program managers.

Open USD (OUSD) Consortium and Key Partners

On June 30, 2026, Open Standard launched Open USD (OUSD), a dollar-pegged stablecoin backed by more than 140 organizations—the broadest stablecoin consortium to date. Key partners include:

• Card networks: Visa, Mastercard, American Express, Discover
• Payment fintechs: Stripe, Klarna, Affirm, Adyen, Block, Western Union
• Banks: BNY (Bank of New York Mellon), U.S. Bank, Huntington, Citizens, Standard Chartered, DBS
• Crypto infrastructure: Coinbase, Ripple, Gemini, MetaMask
• Asset managers: BlackRock
• Big tech: Alphabet (Google), Shopify, IBM, DoorDash, Rakuten

The consortium aims to create an open, low-cost, high-throughput, broadly accessible stablecoin designed to compete with Tether (USDT) and Circle's USDC. The announcement sent Circle's shares down as much as 15%. Open USD plans a late-2026 launch on Solana, Stellar, Base, and Polygon, with zero mint and redemption fees and shared reserve yield.

Visa & Artemis Research: Stablecoins vs. Card Networks for AI Agent Payments

On July 16, 2026, Visa and Artemis jointly released "Agentic Payments from the Ground Up" . Key conclusions:

• Two categories of AI agent commerce: The report distinguishes between macro-commerce (agents performing tasks like booking flights or subscriptions—similar to traditional card transactions) and micro-commerce (high-frequency, ultra-low-value machine-to-machine payments such as API calls and computing resource purchases).

• Card networks are structurally unsuitable for micro-commerce: Traditional card rails, designed for human-scale economics, struggle with percentage-plus-fixed interchange fees, T+1 banking-hours settlement, and static programmability—all of which break on sub-cent, high-frequency agent transactions.

• Stablecoins are the natural rail for AI agent micropayments: The report finds that stablecoins offer the speed, programmability, and cost structure needed for machine-to-machine payments. Visa predicts that cards and stablecoins will coexist—cards for macro-commerce and stablecoins for micro-commerce.

• Practical stage: The report indicates AI agent payments are transitioning from theory to real-world commercial application, noting two machine-native payment protocols already in production: x402 (processed $150 million since May 2025) and MPP (developed by Stripe and Tempo).

Regulatory Tailwinds Driving the Launch

GENIUS Act (July 2025): The Guiding and Establishing National Innovation for US Stablecoins Act was signed into law in July 2025, establishing a federal regulatory framework for stablecoins in the United States. Multiple sources cite the Act as the pivotal regulatory catalyst that enabled the Open Standard/OUSD consortium and Visa's stablecoin expansion. Bloomberg reported that Visa's stablecoin moves were enabled by the "relaxed regulatory environment under the second Trump administration."

Market forecasts: Multiple sources covering the VSP launch reference a Deloitte projection that stablecoin-enabled retail payments will reach $200 billion by 2030. Separately, Citi has projected a $4 trillion stablecoin market.

The combination of the GENIUS Act providing legal clarity, forecasts of a massive addressable market, and the consortium-led Open USD infrastructure created the conditions for Visa to launch VSP as a unified platform connecting the onchain stablecoin economy to its existing payment network of roughly 200 million merchants and 15,000 financial institutions.

What VSP Means for the Future of Payments

The Visa Stablecoin Platform is significant because it marks the moment stablecoins moved from a niche pilot into the core infrastructure of the world's largest payment network. With $7 billion in annualized settlement volume—growing 50% quarter-over-quarter—and 130+ stablecoin card programs expanding across 50 countries, Visa is betting that stablecoins will become a major settlement layer. At the same time, the Visa-Artemis research signals that the real growth catalyst may come from outside traditional finance entirely: autonomous AI agents, which are projected to become the largest single category of stablecoin transaction initiators, surpassing retail and institutional volumes.
