Introduction
OpenAI today rolled out Instant Checkout — a built-in shopping flow that lets U.S. ChatGPT users purchase items inside conversations — and published the Agentic Commerce Protocol (ACP), an open standard co-developed with Stripe to power agentic commerce.
The initial launch supports Etsy sellers now, with plans to connect over a million Shopify merchants shortly. OpenAI says the feature collapses discovery, recommendation and payment into a single conversational flow.
Why it matters
The move shifts ChatGPT from an assistant that finds products to one that can buy them on your behalf. For shoppers it promises faster purchases; for merchants and platforms it creates a new sales channel and changes who controls product discovery and checkout. OpenAI and Stripe are making the checkout tech open source to encourage broad adoption.
How the “Buy it in ChatGPT” Instant Checkout works

Instant Checkout lets a user ask ChatGPT for items (for example, “gift ideas for pottery lovers”) and complete a one-item purchase without leaving the chat.
Payments are processed via Stripe (Apple Pay, Google Pay, or card options) and merchants keep their existing order systems — ACP bridges ChatGPT, merchants and payment rails so agents can place orders programmatically while preserving merchant flows. At launch the feature supports single-item transactions; OpenAI plans multi-item carts later.
Agentic Commerce Protocol explained
The Agentic Commerce Protocol (ACP) is an open standard (co-developed with Stripe) that defines how AI agents, buyers and merchants communicate during a sale.
ACP exposes hooks for product discovery, inventory checks, pricing, and payments so a conversational agent can complete purchases reliably while keeping merchants’ fulfillment and fraud checks intact. OpenAI and Stripe published docs and developer guides for ACP to let platforms and merchants integrate quickly.
Merchant and market impact
For Etsy and Shopify merchants, Instant Checkout creates a new “in-moment” sales channel inside ChatGPT where recommendations and checkout are tightly coupled. Early market reaction pushed Etsy and Shopify stocks up after the announcement.
Merchants pay a commission on completed transactions while users incur no checkout fee, according to OpenAI and partners. Smaller sellers may see improved conversion if agents surface their products at point of intent, but the long-term impact on search rankings and discovery economics will depend on how agents rank and present options.
Privacy, safety and regulatory questions
Shifting commerce into AI conversations raises familiar questions: who controls recommendation bias, how are sponsored results disclosed, and what protections exist against fraudulent charges?
OpenAI says purchases will be clearly identified inside chat and that merchants retain order control, but regulators and privacy advocates will watch payments data flow, ad disclosure and how agentic ranking affects competition. Open sourcing ACP could increase transparency — but it may not eliminate concerns about prominence and platform power.
What shoppers and developers should know now

- Shoppers: Instant Checkout is rolling out to U.S. ChatGPT users (Free, Plus and Pro tiers). Expect simple, single-item buys at first; receipts and order tracking follow merchant flows. OpenAI
- Developers & merchants: ACP docs and Stripe integration guides are live; early adopters should test fulfillment, fraud controls and UX for conversational orders.
Bottom line: OpenAI’s agentic shopping system turns ChatGPT into a transactional platform, not just a discovery assistant. The partnership with Stripe and merchant pipelines through Etsy and Shopify makes the experiment immediately meaningful for commerce — but its ultimate effect on retail, search and platform power will depend on how agents rank products, how merchants adapt, and how regulators react.
Frequently Asked Questions
What is the OpenAI agentic shopping system?
It’s OpenAI’s Instant Checkout plus the Agentic Commerce Protocol (ACP), enabling purchases inside ChatGPT conversations and connecting agents, merchants and payment rails.
Which merchants are supported at launch?
Instant Checkout starts with U.S.-based Etsy sellers. Shopify merchant support (over a million merchants) is coming soon.
How are payments processed?
Payments are processed via Stripe and support Apple Pay, Google Pay and direct card entry; merchants continue to use their existing order and fulfillment workflows.
Will purchases be secure?
OpenAI and Stripe say Instant Checkout uses standard payment protections; merchants retain fraud controls. Users should still verify receipts and monitor statements.
Is the Agentic Commerce Protocol open source?
Yes — ACP is released as an open standard with documentation to help merchants and platforms integrate agentic commerce.

I used OpenAI and Stripe documentation to explain how Instant Checkout and the Agentic Commerce Protocol work, and noted initial merchant support and regulatory questions.
