The Agentic Commerce Landscape: Who Is Building What

A simple 2026 map of agentic commerce: the agents, commerce and payment protocols, card networks, processors, and standards bodies — and the names in each.

The agentic commerce space is busy and can feel confusing. There are many new names, and they all sound similar. This post gives you a simple map.

The trick is to think in layers. Each company or protocol usually works on one layer. Once you see the layers, the whole picture becomes clear.

Here are the six layers, from the agent down to the rules.

1. AI agents and model providers

These are the companies that make the agents that shop for you.

  • OpenAI — ChatGPT can complete purchases in some stores.
  • Google — Gemini and Google's shopping tools.
  • Anthropic — Claude, and the creator of the MCP standard.
  • Microsoft, Perplexity, and others — building assistants that can act.

This layer is the "brain." But a brain alone cannot pay. It needs the layers below.

2. Commerce protocols

These are the rules that let an agent and a store talk about products, carts, and checkout.

  • ACP (Agentic Commerce Protocol) — from OpenAI and Stripe. Open source.
  • UCP (Universal Commerce Protocol) — from Google and Shopify. Decentralized and free to use.
  • MCP (Model Context Protocol) — from Anthropic. This is the discovery layer: it lets an agent find and call a store's tools. It is now governed under the Linux Foundation.
  • A2A (Agent-to-Agent) — a protocol for agents talking to other agents.

Think of this layer as the "shopping language."

3. Payment protocols

These are the rules for how an agent pays and how it proves the payment is allowed.

  • AP2 (Agent Payments Protocol) — started by Google, then given to the FIDO Alliance. It uses "mandates" to prove a human approved the purchase.
  • x402 — from Coinbase. It brings back the old HTTP 402 ("Payment Required") code for machine-native, pay-per-request payments, often with stablecoins.
  • MPP (Machine Payments Protocol) — from Stripe and Tempo. It uses payment "sessions," and is aimed at business use with compliance built in.

This layer is the "money language."

4. Card networks

The big networks have launched their own agent programs. They control how cards are accepted in agent purchases.

  • Visa — Visa Intelligent Commerce.
  • Mastercard — Mastercard Agent Pay.
  • American Express — an agentic commerce program, with a commitment to cover some wrong purchases made by verified agents.

This layer decides if a real card payment goes through.

5. Payment processors and infrastructure

These companies do the real work of moving money and running the plumbing.

  • Stripe — deep in many protocols (ACP, MPP, and support for x402).
  • PayPal — building agent payment support.
  • Coinbase — the team behind x402 and stablecoin rails.
  • Cloudflare — helps prove which agents are real traffic (signed agents / Web Bot Auth), and runs infrastructure for agent payments.

This layer is the "engine room."

6. Standards bodies

These groups do not sell products. They set the shared rules so everyone can work together.

  • FIDO Alliance — now home to AP2 and agent authentication work.
  • W3C — web standards, including verifiable credentials and bot authentication drafts.
  • IETF — internet standards, including payment-related drafts.
  • EMVCo — payment card standards.
  • Linux Foundation — now governs MCP.

This layer is the "rule book." It moves slowly, but it decides the long-term winners.

One recent signal to watch

In September 2026, Visa, Mastercard, and Ant International announced they would work together on a "Know Your Agent" (KYA) framework. The goal is a shared way to check the identity of an AI agent.

This is important because agent identity has no single standard yet. But note the honest part: it was announced as a shared plan, not a finished specification. There is no public spec or timeline yet. It is a signal of direction, not a shipped product.

How the layers fit together

A full agent purchase touches many layers at once:

  • The agent (layer 1) uses a commerce protocol (layer 2) to shop.
  • It uses a payment protocol (layer 3) to prove approval and pay.
  • The payment runs through a card network (layer 4) and a processor (layer 5).
  • All of it follows rules set by standards bodies (layer 6).

No single company owns the whole stack. That is why so many partnerships are forming.

What to watch next

  • Identity. Who wins the "Know Your Agent" problem?
  • Payments. Do open protocols or the card networks' own rails take the lead? Right now they are merging, not fighting.
  • Live versus announced. Keep asking if a claim is live, announced, or only contributed to a standard.

If you keep this six-layer map in your head, every new announcement will fall into place.
