Instant Checkout

Instant Checkout is OpenAI's implementation of agentic checkout in ChatGPT — a buyer moves from a product question to a completed purchase in a few taps without leaving the chat.

Instant Checkout is powered by the Agentic Commerce Protocol, the open standard OpenAI co-developed with Stripe. The merchant processes payment and fulfills the order on its existing infrastructure and remains the merchant of record. It is the reference example of a branded agentic-checkout experience.

For brands, Instant Checkout is the live proof that the agentic-commerce category is operational, not theoretical. Buyers are completing real purchases inside ChatGPT today. The strategic question is no longer whether to prepare — it is whether the brand is transactable before its category competitors are.
