Agentic Commerce
Commerce in which an AI agent shops, negotiates, and pays on behalf of a human (or a business buyer) — and merchants accept it as a first-class transaction class with its own trust signals, scoped credentials, and dispute rails. The phrase covered merchant-side automation through 2024; in 2025 it was redefined by a coordinated protocol push from Visa (Intelligent Commerce + Trusted Agent Protocol), Mastercard (Agent Pay + Agentic Tokens), and Stripe × OpenAI (Agentic Commerce Protocol, with ChatGPT Instant Checkout going live across 1M+ Shopify merchants), and now overwhelmingly refers to the *buyer-side* surface. The original merchant-automation meaning still applies and overlaps with Agent Payments and Delegated Purchasing.

Example
A user asks ChatGPT to 'order more of the same nursing pads I bought last month.' ChatGPT identifies the SKU, surfaces the merchant via the agent-indexed catalog, and routes the order through the Stripe × OpenAI Agentic Commerce Protocol using a scoped Visa agentic token. The merchant receives a Trusted Agent Protocol signal — 'agent X, authorized by cardholder Y, max $80, expires in 24h' — and processes the order on its normal Shopify checkout rail. The full loop happens inside the chat, with a 90-second user-cancel window before fulfillment.
Frequently asked questions
- Is agentic commerce the same as ecommerce AI?
- Not anymore. 'Ecommerce AI' is the merchant-side toolkit (recommendations, dynamic pricing, abandoned-cart recovery). 'Agentic commerce' in 2025-2026 usage is the buyer-side surface: an agent acting as the shopper, with delegated authority and a scoped payment credential. The merchant-side meaning still exists and the two stacks meet at the checkout — but the new phrase usually refers to the buyer-agent side.
- Which protocols define the trust signals?
- Three lanes as of 2026: Visa's Trusted Agent Protocol (open, merchant-facing trust signal), Mastercard's Agent Pay with Agentic Tokens (network-issued scoped credentials), and the Stripe × OpenAI Agentic Commerce Protocol (transport between LLM apps and merchants, used by ChatGPT Instant Checkout). Most production builders implement two of the three.
- What does this mean for merchants?
- Three things change. (1) Catalog discoverability — agents can only buy from merchants whose products are findable by the agent's index. (2) Trust-signal handling — when an agent fronts the buyer, fraud/personalization signals are lost unless the new agent-trust signal is plumbed in. (3) Pricing — agents are dramatically more price-sensitive than humans on commoditized SKUs, less so on differentiated ones, so the price strategy needs to be SKU-segmented.
