Stripe Infrastructure: Built on battle-tested payment rails with existing merchant accounts and global coverage. Delegated Tokens: Users grant agents limited spending authority through single-use, time-bound, amount-restricted tokens. Centralized Listing: Merchants list via Shopify, OpenAI curates and surfaces products.
OpenAI’s Agentic Commerce Protocol (ACP), launched September 2025 with Stripe, was the first major protocol to enable AI-driven purchasing at scale—turning ChatGPT’s 810 million daily users into a commerce platform.
Checkout-Focused Scope
Unlike UCP’s full-journey approach, ACP focuses specifically on checkout and transaction flows: payment processing and transaction completion. Discovery and cart management happen within ChatGPT’s conversational interface. Post-purchase handled by merchants.

Delegated Tokens: Users grant agents limited spending authority through single-use, time-bound, amount-restricted tokens. Centralized Listing: Merchants list via Shopify, OpenAI curates and surfaces products.
Partners & Monetization
Core partners: OpenAI (810M users) + Stripe (payments) + Shopify (merchants). Retail partners: Etsy, Instacart, Target, Booking.com + full Shopify network. Monetization: Transaction fees. On a $100 purchase, OpenAI takes a small percentage, merchant receives $97+.
ACP’s bet: 810 million daily users is the distribution. Stripe infrastructure is the trust. Transaction fees fund AI’s future. Every purchase completed in ChatGPT generates revenue that funds compute.
