Walmart has launched an Agent Gateway that lets AI assistants such as ChatGPT, Gemini, and Muse search its stores and complete purchases for customers — the opposite strategy to Amazon, which has been blocking outside shopping agents. It matters because the world’s biggest retailer is betting that your next shopping trip may start with an AI agent, not a search box.
October 21, 2026 — Walmart announced the tools on Wednesday at the Masters of Scale Summit in San Francisco, where President and CEO John Furner laid out the company’s push to be ready for agentic commerce across both Walmart and Sam’s Club.
How the Walmart Agent Gateway works
The Agent Gateway is a platform — built as an MCP server, using the model context protocol originally created by Anthropic — that lets approved AI assistants connect directly with Walmart and Sam’s Club systems to search products and complete purchases. Walmart says the Gateway can also help an agent shop for your usual brands or items without you having to share your personal information or purchase history directly with the agent.
Alongside the Gateway, Walmart is publishing terms for AI agents that set out how they must operate and what they may do on its site. Agents cannot access customers’ payment card data, cannot act beyond what the shopper intends, and can only access the information a given task needs. Agents that break the rules will be blocked. Walmart’s standard returns process applies to agent-made purchases — including when an agent does not act as intended.
Agent Profiles put the shopper in control
Rolling out next month, Agent Profiles let you authorize each AI agent you use as a separate profile inside your Walmart account. The profile is created the first time you shop through an agent via the Gateway; you link it to your account and set your controls. Agent purchases are tracked separately from your own orders, and you choose the leash: require approval for every transaction, or let the agent buy on its own up to a spending limit you set — Walmart gives examples such as $50, $100, or $200. You can revoke access or delete a profile at any time.
Walmart compares the setup to adding an authorized user to a credit card: their transactions are identified as theirs, and you can cap their spending. The tools are available to anyone with a Walmart account — no Walmart+ membership is required.
Why it matters
This is a genuine fork in retail strategy. Amazon, the largest US online retailer, has taken the harder line — blocking third-party shopping agents while promoting its own AI tools. Walmart is doing the reverse: giving outside agents an official, governed front door, and competing on control and trust instead. Mizuho analysts said the added guardrails could help build trust in what is still an experimental way to buy things. Our take: whoever owns the rules for how agents shop will matter as much as whoever owns the agent. If assistants become the starting point for shopping, being agent-ready early — with spending limits and returns shoppers understand — is a real head start. Everything AI, tested: we will be watching whether shoppers actually hand their carts over.
