Can AI agents shop for your customers? What Walmart's Agent Gateway means for sellers
Yes, and Walmart is now building for it. On 21 October 2026 Walmart announced Agent Profiles, the Walmart Agent Gateway and terms for AI agents. Shoppers will be able to let an AI agent buy for them, approving every order or setting a spending limit. For smaller stores, the lesson is to make products, prices and policies easy for machines to read.
- Agent Profiles, due within a month, give each AI agent its own profile in a customer's account, with its purchases shown separately.
- Customers can approve every agent purchase or set a spending limit, for example $50, $100 or $200, and switch an agent off at any time.
- Agents never receive card details, and agents that break Walmart's terms will be blocked from its site.
What happened
In its announcement, Walmart explains that AI agents already shop on its site by signing in with the customer's account, so their orders get mixed in with the customer's own. The new Agent Profiles separate them. Walmart compares it to adding a cardholder to your credit card: the agent can pay, within limits you set.
Walmart also says agents see the same prices as people. Its returns process still applies, even when an agent doesn't act as intended.
What this means for your site or store
You don't need to be Walmart for this to matter. When a retailer of Walmart's size builds rules and a dedicated entrance for AI shoppers, agents buying on someone's behalf stops being an experiment. Those agents will compare stores, and they favour the ones whose product names, prices, stock, shipping and return policies are clear and consistent.
Start with the basics: accurate product data, schema markup (code that labels products and prices for machines), and a robots.txt that doesn't block the AI agents you want. Our news on BigCommerce turning on WebMCP shows how platforms are adding the next layer.
The technical details
The Agent Gateway is an MCP server. MCP (Model Context Protocol) is a standard way for an agent to call a site's functions directly, instead of clicking through pages built for humans. Walmart says browser-based shopping "can be slow and error-prone" for agents. The gateway starts as a beta for companies and developers, and it can help an agent find a customer's usual items without sharing their purchase history.
