Agentic Commerce

Agent Commerce · AI Commerce

Definition

Agentic commerce is a model of trade where an AI agent autonomously finds products, compares options and completes a purchase on a person's behalf through standardised protocols for interacting with stores.

What agentic commerce is

Traditional e-commerce assumes an active shopper: they open the site, type a query, browse the
catalogue, compare products and press buy. Agentic commerce changes that model: the person states a
task in natural language and an AI agent executes the whole chain.

Buy me the coffee beans I usually get, but with delivery by tomorrow — and the agent finds the
product, checks stock and a delivery slot, compares alternatives and places the order using the
shopper’s payment token.

The agentic commerce stack

Person
  ↓ a natural language request
AI agent (ChatGPT, Gemini and others)
  ↓ MCP / ACP / AP2
Store catalogue + order API
  ↓ shared payment token / network agent token
Order confirmation

Every layer needs standardisation: capability discovery protocols (MCP), ordering protocols (ACP),
payment mechanisms (tokens, mandates).

What changes for a retailer

Before	Now
The storefront is the site or the app	The storefront is the agent’s answer plus an API
SEO is the main discovery channel	SEO plus catalogue agent-readiness
Conversion is a UX problem	Conversion is a data and API quality problem
A funnel of four to seven steps	A funnel of one or two (intent → purchase)

Important: in agentic commerce a store competes not for a position in search results but for
the agent choosing its catalogue — on data completeness, price, API availability and response
speed.

Where it stands in 2025–2026

The first working implementations are live: ChatGPT Instant Checkout (United States, Etsy and
Shopify merchants, from September 2025), with Google and other assistant vendors building comparable
transactional paths. Analysts project global agent purchase volume of 3 to 5 trillion dollars by
2030, conditional on broad adoption of the protocols and payment standards.

The practical priority for a retailer in the meantime is unglamorous: a structured catalogue, a
high-quality product feed, machine-readable product data, and an integration path to whichever
agent ecosystems matter in its markets.

Frequently asked questions

How does agentic commerce differ from ordinary e-commerce?

In classical e-commerce the shopper visits the site, searches and places the order. In agentic commerce an AI agent does it on their instruction, with no site visit, directly through an API. The retailer is now selling to agents rather than to human visitors.

Which protocols does a store need?

ACP (OpenAI and Stripe) for agent traffic through ChatGPT, AP2 for agents in the Google ecosystem, and regional equivalents where they exist. They all solve one problem: a standard way for an agent to find a product and place an order.

When does agentic commerce become a meaningful channel?

The first commercial transactions through agents ran in 2025 (ChatGPT Instant Checkout). Meaningful volume for a mid-sized retailer is a question of 2026–2028. Preparing the infrastructure — catalogue, API, machine-readable data — is best started early, because it takes two to six months.
