Mastercard launches Agent Pay for Machines to let AI agents pay each other in micropayments

Mastercard launched Agent Pay for Machines on June 10, 2026, a payment service that lets AI agents transact with one another at machine speed, including micropayments as small as fractions of a cent. The release pushes the card network deeper into agentic commerce, where software agents buy and sell on a user's behalf.

According to Mastercard's Agent Pay for Machines announcement, the service lets agents be credentialed and permissioned with programmatically enforced authorization rules and spending limits, then settles their transactions across multiple payment rails — cards, bank accounts, and stablecoins — on Mastercard's network. More than 30 companies across payments, technology, and digital assets are among the first to support it, including fintech Adyen, crypto exchange Coinbase, and web-infrastructure firm Cloudflare. Polygon is also among the initial participants.

Routing agent-to-agent payments through an established card network, rather than crypto rails alone, gives the model a recognizable trust and dispute framework. Jorn Lambert, Mastercard's chief product officer, said the service "will create the conditions for a superbloom of AI business models," enabling services to be bought and sold among agents "at fundamentally different scales than payments today — very high volumes, very small values, very fast and at extremely low latency."

The launch is early-stage. Agent-driven payments raise unresolved questions about authorization, liability, and fraud when transactions execute faster than a human can review them — issues the company did not detail in the announcement.

The protocol arrives in a crowded field. Coinbase has its x402 protocol, Stripe and Tempo are working on Machine Payments Protocol compatibility, and other large players are building agent-payment standards. Whether Mastercard's card-network reach and 30-plus launch partners translate into adoption will depend on how quickly agentic shopping moves from pilots to real spending.
