Summary
Editor's update, October 2026: 19 Oct 2026 accuracy audit: reframed around ACP and the March 2026 deprioritisation of Instant Checkout; standards score raised.
Agentic Commerce Protocol (ACP) checkout for ChatGPT shopping. OpenAI deprioritised Instant Checkout as a standalone feature in March 2026; ChatGPT shopping now centres on product discovery, with merchants able to use their own checkout.
OpenAI Instant Checkout let ChatGPT users buy from merchants without leaving the chat, using the Agentic Commerce Protocol (ACP), an open-source standard OpenAI co-developed with Stripe. ACP covers checkout coordination and secure sharing of payment credentials, and businesses remain the merchant of record. It is aimed at merchants and commerce platforms rather than publishers.
The most durable part of the offering is the protocol rather than the in-chat checkout. ACP is Apache 2.0 licensed, works with any compatible payment provider (Stripe's Shared Payment Token was first), and supports physical and digital goods, subscriptions and asynchronous purchases. ChatGPT itself gives merchants access to a very large user base researching products.
The main limitation is that OpenAI said in March 2026 that it would deprioritise Instant Checkout as a standalone feature after weak uptake, and refocus ChatGPT shopping on discovery and comparison, with merchants able to keep their own checkout. Participation requires an application, and there is no publisher revenue model: content publishers do not earn from purchases made through ChatGPT.
