The biggest shift in agentic commerce is happening before checkout, as AI agents begin deciding what to buy, which service to use, how much to spend and when to transact. Agentic commerce isn't primarily about AI shopping. It's about creating an economic system in which software can act, transact and fulfill on behalf of humans.

The numbers show that it is already underway. Gartner predicts by 2028 that 90% of B2B buying will be AI-agent intermediated, representing more than $15 trillion in B2B purchases. Olas has recorded more than 14 million agent-to-agent interactions across its ecosystem. Para’s wallet infrastructure now serves more than 15 million end users. More than 30 companies have joined Mastercard's Agent Pay ecosystem. And Polygon has become a major rail for x402, processing millions of machine-to-machine transactions.

The infrastructure race is on.

What Agentic Commerce Really Means

In speaking with David Minarsch, founding member of Olas and and CEO of Valory, I heard perhaps the simplest definition of agentic commerce. “If one software program purchases a service from another software program.”

That idea becomes far more powerful when it happens millions of times, with no human approving each transaction. The 14.5 million interactions inside the Olas ecosystem show what that looks like at scale, with software agents finding, hiring, and paying other software agents to get work done.

But an agent cannot transact without a financial identity and a permission structure.

Agentic commerce can be defined by four layers: payments, authorization, agent to agent and fulfillment. Each layer solves a different problem: moving money, controlling what an agent can spend, letting agents hire each other, and confirming the work got done.

Agentic Commerce Runs On Permissions

Nitya Subramanian, founder and CEO of Para , is building the layer that determines what an agent can do with money. She sees the wallet as the control point for agentic commerce.

She told me that “wallets are ultimately the authorization and control flow layer of anything that happens.”

An agent may be autonomous, but autonomy does not mean unlimited access. The wallet can establish spending limits, approved transaction types, protocol restrictions and other boundaries, and Para’s transaction permission infrastructure is designed to ensure those controls at the wallet layer.

Then comes the other half of the transaction: fulfillment.

“Purchasing is not enough. You also need fulfillment,” says Will Papper Director of Product at Cloudflare , which is connecting agents to the services they consume.

Paying is only the start. The agent also needs to receive the service, confirm it was delivered and evaluate whether the result was good enough to buy again.

The New Shape Of Agentic Commerce

Traditional commerce was designed around humans making relatively large, intentional purchases. Agentic commerce can involve thousands of tiny transactions: an API call, a piece of data, a prediction, a few seconds of compute, an article or an image.

This is why Polygon’s role matters. It has become a rail for x402, an emerging payment standard that lets software pay for a web service in the moment it consumes it, with no account signup and no checkout page.

Mastercard is explicitly building for this world, describing machine payments as potentially high volume, low value and low latency. Its Agent Pay ecosystem now spans more than 30 companies across payments, AI, wallets and infrastructure.

Visa, Mastercard, and Stripe are building agentic payment rails. Cloudflare is wiring agents into services. Para is building the wallet and authorization layer. Olas is proving out agent to agent markets. There is no single winner yet.

Who Wins Agentic Commerce

The race is to build the infrastructure that lets software become an economic actor What does that mean? It means giving agents identity, money, permissions, reputation, and the ability to transact with agents and services.

The technology will eventually disappear into the experience. “If you don’t know you’re using it, we’ve done our jobs right,” Papper says.

The biggest test will come the day a purchase completes, the service arrives and no person though about any of it. The human checkout survived every previous wave of technology, but agentic commerce may finally make it optional.
