OpenAI brings shopping directly into ChatGPT with 'Instant Checkout' feature

OpenAI has brought shopping directly into ChatGPT, introducing an Instant Checkout for U.S. users and publishing an Agentic Commerce Protocol (ACP) that standardises how merchants expose products, complete checkout and process payments via trusted providers.

The launch has initially focused on Etsy sellers, with Shopify support set to follow.

Instant Checkout has arrived inside ChatGPT

Instant Checkout has enabled ChatGPT users in the United States to purchase items in the chat. The first wave has covered domestic Etsy listings, with integration for Shopify merchants expected next. Each purchase has been limited to a single item at launch, and OpenAI has said it plans to add multi‑item carts and broaden availability.

Payments are processed through Stripe, with users able to complete transactions using Apple Pay, Google Pay, Stripe, or a card on file.

OpenAI has not charged users a fee; participating merchants have paid a commission per sale, with commercial terms undisclosed. Purchases have been clearly labelled within ChatGPT to distinguish commerce from general answers.

The move has extended OpenAI’s shopping work from earlier this year—when ChatGPT’s search experience has begun surfacing product results with images and reviews—towards “closed‑loop” buying inside the assistant.

OpenAI, led by CEO Sam Altman, has repeatedly framed ChatGPT as a general‑purpose assistant that can take useful actions for users.

What is the Agentic Commerce Protocol?

OpenAI has described the ACP as an open set of specifications—covering Agentic Checkout, Delegated Payment, and Product Feed—that allows merchants and payment service providers (PSPs) to integrate with ChatGPT and, in time, other agentic front ends. The protocol has been developed with Stripe and is being open‑sourced.

Under the Delegated Payment spec, ChatGPT has shared a constrained, single‑use payment payload with a merchant’s PSP or PCI‑level vault.

The PSP has returned a scoped token, which OpenAI has forwarded to complete the order. OpenAI has not been the merchant of record; settlement, refunds and chargebacks have remained with the merchant and its PSP.

How it works for users and merchants

For users, the flow has resembled a standard checkout, only inside the conversation: select an item surfaced by ChatGPT, confirm details such as size and delivery address, and authorise payment using a stored or new method. Purchases have been annotated in‑chat and receipted through the merchant’s normal systems.

For merchants, ACP has provided structured ways to publish catalogues (via Product Feed), accept agent‑initiated orders (via Agentic Checkout), and process payments with their existing PSPs (via Delegated Payment). OpenAI has said this approach has let merchants retain their payment relationships and operational controls while making their inventory “legible” to AI agents.

OpenAI has indicated that Shopify support and multi‑item carts are on the roadmap, and that the underlying ACP and checkout components are being open‑sourced to encourage wider adoption across the commerce ecosystem.
