Visa, Mastercard, and Fiserv joined a group to set rules for AI-agent payments.
The coalition has 26 members.
It aims to avoid fragmented standards before regulators step in.
What happened
Visa, Mastercard, and Fiserv joined the Agentic Payments Alliance (APA), a 26-company coalition led by stablecoin firm Rain, to set common standards for AI-agent payments.
Why it matters
Without shared rules, each firm's separate protocols could fragment the market. The APA aims to prevent that by requiring cross-compatible platforms, and it wants to define governance before regulators do.
What to watch
The agentic commerce market could grow at a 35.7% CAGR from 2026 to 2033, and McKinsey estimates agentic AI activity could reach $3 trillion to $5 trillion by 2030.

The move marks a proactive step by major payment networks to shape the rules for AI-agent-driven commerce before federal regulation arrives. Earlier, each firm was developing separate protocols, risking fragmentation that could stall market growth. By joining the APA, they commit to cross-compatible platforms, which could help the market expand smoothly. The estimated growth—35.7% CAGR from 2026 to 2033 and $3 trillion to $5 trillion by 2030—suggests a significant opportunity, but near-term impact may be limited. For Visa and Mastercard, the key is staying essential as payments shift to blockchain, while Fiserv aims to lock in merchants by easing the transition. The alliance's focus on digital identity, loyalty programs, and fraud detection addresses core challenges in machine-to-machine payments.
