Visa, Mastercard, Fiserv join 26-member group writing AI payment rules

Visa, Mastercard, and Fiserv joined a 26-member coalition setting common standards for AI agents that handle payments.

Visa, Mastercard, and Fiserv joined the 26-member Agentic Payments Alliance to set common rules for AI agents that execute payments, a market McKinsey projects could reach $3 trillion to $5 trillion by 2030.

The coalition, assembled by stablecoin infrastructure firm Rain, aims to establish shared standards for how autonomous AI agents manage digital identities, process loyalty programs, and detect fraud, the founding members said. The APA's other founding members include Circle, the Solana Foundation, and Remitly.

Grand View Research projects the agentic commerce market to grow at a 35.7% compound annual rate from 2026 to 2033. For Visa and Mastercard, routing agentic transactions through their own tokenized networks — Visa's Trusted Agent Protocol and Mastercard's Agent Pay — keeps them in the loop as payments shift from card networks to blockchain platforms. For Fiserv, joining lets its merchants accept agentic AI payments without rebuilding their infrastructure.

Why the Alliance Matters for Agentic Commerce

Today most online purchases are made manually or through an AI chatbot's recommendations. With agentic commerce, AI agents proactively scour dozens of sites for products, calculate the final total, and handle checkout once the end user approves. Agents can also resolve unauthorized or disputed payments without human intervention, using stablecoins pegged to fiat currencies to fund machine-to-machine payments.

Before the APA, Visa, Mastercard, Fiserv, and others had developed separate protocols for agentic payments. That fragmentation could slow market expansion. The APA requires its traditional finance and blockchain members to build cross-compatible platforms that communicate with one another. The coalition also seeks to define the industry's governance and frameworks before federal regulators write their own rules for machine-to-machine payments.

What It Means for Visa, Mastercard, and Fiserv

For Visa and Mastercard, the trusted payment networks stand to lock in merchants as more consumers automate shopping with AI agents. Their established trust also means agentic transactions on their platforms should be treated as legitimate rather than malicious. For Fiserv, which provides payment processing and millions of point-of-sale systems, joining lets its merchants accept agentic AI payments without rebuilding their infrastructure, keeping them from losing customers to AI-first sales channels.

The near-term financial impact is modest, but the strategic stakes are clear. Visa and Mastercard are defending their role as gatekeepers of trusted transactions as commerce shifts to machine-to-machine payments. The APA's common standards reduce the risk that fragmented protocols slow adoption of agentic commerce, a market Grand View Research projects to grow at a 35.7% compound annual rate through 2033.
