Mastercard Launches Agent Pay for Machines. Polygon Is Part of the Ecosystem Supporting It

Today, Mastercard introduced Agent Pay for Machines (AP4M), a new service that allows machine-driven transactions to be permissioned, orchestrated, and settled at machine speed across its global payments network. 

More than 30 companies are among the first participants and supporters. Polygon is one of them, alongside Adyen, Ant International, Checkout.com, Cloudflare, Coinbase, Getnet by Santander, Global Payments, Solana, and Stripe.

We think this launch matters because of what it says about where payments are heading. 

Agentic commerce already runs on the Polygon network. As of June 2026, 95% of all x402 transactions (the open protocol that lets AI agents pay for resources over HTTP) settle through Polygon, more than 15.5 million agent payments to date. The economics hold up: finality in about five seconds, fees in fractions of a cent, and our intent-powered orchestration layer of the Open Money Stack finding the best route from a single instruction.

AI agents are becoming full economic actors, participating in ways that are essential to their own prosperity: buying compute, data, hosting, and services on behalf of the businesses that deploy them. 

One human request can now fan out into a chain of transactions executed automatically across providers.

Agent payments look substantially different from human checkouts. 

They are continuous instead of one-off, initiated by software and not people, and often are only fractions of a cent. A logistics agent might pay for freight, reserve loading-bay access, and settle warehouse fees as a shipment moves. That’s dozens of small transactions where a person would have made one.

Existing payment infrastructure was designed for people clicking buy.

Machine-driven commerce needs something different: transactions that are credentialed, permissioned, and settled reliably at volumes and values today's systems were never built for.

AP4M is Mastercard's answer. It builds on the Agent Pay program Mastercard introduced in 2025 and rests on four capabilities: 

That last rail is where we come in. 

Stablecoin settlement is what the Polygon network does at scale today: transactions reach finality in about five seconds and cost fractions of a cent, which is the economic profile machine-driven payments require. A payment model built on very high volumes and very small values only works when the settlement layer doesn't eat the margin.

We built the Open Money Stack (our end-to-end platform for global stablecoin payments) so businesses can move money on those rails without assembling the infrastructure themselves. Agent-driven commerce is a natural extension of that work, and supporting AP4M connects it to one of the largest payment networks in the world.

"Polygon Labs is building the infrastructure for programmable payments and agent-driven commerce at global scale, with the Open Money Stack helping make digital financial services more accessible and interoperable," said Aishwary Gupta, global head of business at Polygon. "Mastercard's exploration of machine payments underscores how blockchain and traditional payment networks can work together to unlock new consumer and business experiences while accelerating the evolution of the digital payments ecosystem."

Mastercard and its partners are now validating priority use cases, establishing common rules, and working to accelerate adoption across industries. We expect agentic payments to develop the way most payment infrastructure does: quietly, in the background, until one day the volume is impossible to ignore.

The direction is what counts. Card networks, PSPs, and blockchain networks are building toward the same future, one where software transacts on its own and settlement has to keep up. We're glad to be building it together.
