For most of 2024, the question about AI assistants and commerce was theoretical: "will users actually buy things inside ChatGPT, or just use it for research?" In September 2025, OpenAI started answering the question. By May 2026, the answer is settled — yes, they will.
OpenAI launched ChatGPT Instant Checkout in September 2025, initially with Etsy sellers and the Agentic Commerce Protocol (ACP) developed jointly with Stripe (OpenAI, Buy it in ChatGPT). Shopify merchant onboarding began in late January 2026. On October 28, 2025, OpenAI and PayPal announced a partnership that makes PayPal the first payments wallet available inside ChatGPT, connecting "tens of millions of small businesses and the largest brands in the world" to the in-chat shopping surface (PayPal Newsroom, OpenAI and PayPal team up).
The merchant economics: OpenAI charges merchants a 4% transaction fee on every Instant Checkout purchase. Shoppers pay nothing extra — the fee comes out of the merchant's margin (Get ChatAds, ChatGPT Checkout explained).
For freelance creators, affiliates, and commerce consultants, this changes the game in three concrete ways.
