The agent-payment stack shipped this year.
Every protocol that lets an autonomous AI buyer discover, evaluate, negotiate with, and pay your business shipped in the last six months. The companies inside the coalition capture the agent-buyer revenue everyone else’s checkout blocks. The market is still early, but the direction is no longer speculative.
What the analysts say.
Two sourced figures Agentify ships against. We don’t invent numbers. Every claim on this site ties back to a primary source.

Anthropic's MCP went from a startup spec to a Linux Foundation standard in 13 months. Every major AI platform now speaks it.
Six months. Six protocols.
The agent-buyer stack didn’t arrive slowly. It landed in consecutive quarters, each launch endorsed by the next.
- Sept 2025
Agentic Commerce Protocol (ACP)
OpenAI and Stripe shipped end-to-end agent-driven checkout sessions. The first protocol an autonomous buyer can actually transact through.
- Nov 2025
Stripe Shared Payment Tokens (SPT)
A scoped payment token an agent can use on behalf of a human cardholder, with budget and intent constraints baked into the token itself.
- Dec 2025
MCP → Linux Foundation
Anthropic donated the Model Context Protocol to the Linux Foundation, making it the neutral standard that every major model host now implements.
- Jan 2026
Universal Commerce Protocol (UCP) at NRF
Google, Shopify, Walmart, Target, Etsy, and Wayfair launched UCP - endorsed by Visa, Mastercard, AmEx, PayPal, Adyen, Worldpay, Salesforce, Home Depot, Lowe's, Macy's, Sephora, Ulta, and more.
- Q1 2026
Visa Intelligent Commerce + Mastercard Agent Pay
The networks issued agentic network tokens - scoped 'cards' that only work for a specific agent, intent, and budget. The fraud rails finally stopped flagging agent traffic.
The names already in.
