Walmart announced on Wednesday that it will open its storefront to outside AI agents, letting them search and buy on behalf of customers — with a rulebook. The rollout, previewed by CEO John Furner at the Masters of Scale Summit in San Francisco, positions the world's largest retailer on the opposite side of a divide that Amazon has spent the past weeks hardening: Amazon has blocked AI shopping agents, including Perplexity's browser agent and Meta's Muse assistant, while Walmart is building them a door.
The core of the announcement is Agent Profiles, rolling out within the next month. Each AI agent a customer uses gets its own dedicated profile inside the Walmart account, the same way an authorized user is added to a credit card. By default every agent purchase requires approval, but shoppers can instead set a spending cap — Walmart gave 50, 100 and 200 Dollars as examples — within which the agent can transact on its own. Agent orders are listed separately from the customer's own, and a profile can be deleted at any time.
The plumbing is the Agent Gateway, a Model Context Protocol server that approved agents connect to directly instead of clicking through a website built for humans. MCP, the open standard originally created by Anthropic, lets an agent search inventory and complete purchases through a structured interface. Walmart says agents see the same prices a person sees, and that the gateway can point an agent to a customer's usual items — the company's example is a standing sourdough bread or milk brand — without exposing the broader purchase history. The gateway starts as a beta for companies and developers.
The terms are strict. Agents must not act beyond what the shopper intends, cannot access or change payment methods, and only get the data needed for the task at hand. Walmart's normal returns process applies even when an agent misfires — a deliberately customer-friendly condition aimed at the obvious fear of agentic shopping — and agents that break the rules get blocked from the site entirely.
Walmart is not starting from zero. It already integrates with Meta's Muse, ChatGPT, Gemini and other assistants, and runs its own Sparky assistant. The new tools work for both Walmart and Sam's Club, and no Walmart+ membership is required — any account can authorize an agent.
The strategic framing is hard to miss. Beyond Amazon, plenty of travel and booking sites have locked agents out outright, betting that agent traffic is either worthless or dangerous. Walmart is betting the opposite: that whoever builds the trusted interface for agent checkout will own the next layer of retail. Google is pushing a universal shopping cart for agents and American Express has proposed a purchase-intent framework, so the standards race is already on.
For the industry, the Walmart move turns an abstract debate about agent permissions into something concrete: caps, approvals, audit trails and terms of service. The open questions are commercial rather than technical — which model partners get gateway access, how discovery revenue works when an agent stands between the shopper and the shelf, and whether Amazon's walled approach starts leaking share among customers who already delegate their errands.
