ACP launches with Instant Checkout in ChatGPT

OpenAI and Stripe have introduced the Agentic Commerce Protocol alongside Instant Checkout in ChatGPT. The initial experience lets US users buy from US Etsy sellers within a conversation. Shopify merchants are described as coming next. OpenAI’s announcement.

ACP provides a common format for commerce between agents and businesses. The customer confirms a purchase; the merchant remains responsible for processing and fulfilling it. Stripe describes secure, delegated payment credentials as part of that exchange. Stripe’s explanation.

The immediate evidence is a bounded shopping experience. It establishes a starting point for agent-mediated checkout, with the geography and merchant scope specified. It does not establish general Australian availability.

The question to follow is what happens as ordinary shopping requirements arrive: different payment methods, delivery options, customer accounts and the merchant’s existing service commitments.
