September 29, 2025 – OpenAI has introduced Instant Checkout in ChatGPT, marking its first step into AI-powered commerce. The feature, built with Stripe and powered by the new Agentic Commerce Protocol, allows users to complete purchases directly within a chat.

Instant Checkout: Shopping Inside ChatGPT

Starting today, U.S. ChatGPT Plus, Pro, and Free users can purchase products directly from U.S.-based Etsy sellers without leaving the app. Support for over one million Shopify merchants, including major brands such as Glossier, SKIMS, Spanx, and Vuori, will follow soon.

Currently, Instant Checkout supports single-item purchases, with multi-item carts, more merchants, and international expansion planned next.

For users, the flow is simple:

1. Ask a shopping-related question in ChatGPT.

2. Browse relevant, unsponsored product results.

3. Tap Buy, confirm order details, and complete payment within the chat.

Merchants handle fulfillment, payments, and support through their existing systems, while ChatGPT acts as a secure AI agent facilitating the transaction.

The Agentic Commerce Protocol

At the core of this update is the Agentic Commerce Protocol (ACP), an open standard co-developed by OpenAI and Stripe. ACP allows AI agents, people, and businesses to coordinate purchases seamlessly.

Key features include:

• Works across platforms, payment processors, and business types.

• Quick integration without backend overhauls.

• Merchants retain full ownership of the customer relationship—including fulfillment, returns, and support.

• Stripe merchants can enable agentic payments with one line of code. Others can integrate via Stripe’s Shared Payment Token API or the Delegated Payments Spec.

OpenAI has open-sourced ACP, inviting merchants and developers to begin building integrations immediately.

Built for Trust

The system is designed with user trust and security at its core:

• Explicit user confirmation at every step.

• Encrypted payment tokens restricted to specific amounts and merchants.

• Minimal data sharing, with only necessary details passed to merchants.

Partner Perspectives

• Stripe: “We’re proud to power Instant Checkout in ChatGPT and co-develop the Agentic Commerce Protocol to help businesses and AI platforms build the future of commerce,” said Will Gaybrick, President of Technology and Business.

• Etsy and Shopify will be among the first major merchant ecosystems connected to the protocol.

Looking Ahead

OpenAI sees this as just the beginning of agentic commerce—where AI goes beyond recommendations to actually complete transactions on behalf of users. With hundreds of millions of ChatGPT users already engaging weekly, Instant Checkout could redefine how people discover, decide, and buy products online.

For developers: Documentation for the Agentic Commerce Protocol is available today. Interested merchants can apply to list their products for ChatGPT’s Instant Checkout experience.
