Walmart Will Let Your AI Helper Shop for You, With Limits
Walmart said it will let customers connect their own AI helpers to Walmart.com so the helpers can shop for them. Each purchase needs a yes from the customer, and people can set a spending limit. The Verge reported the news on October 21, 2026. The feature is set to roll out the following month.
The setup is called Agent Profiles. An AI helper's purchases need approval by default. Shoppers can also set a budget, with one example capped at $100. They can check the helper's purchases apart from their own orders, and they can turn the helper off at any time.
Walmart says the helpers connect through a gateway that uses the Model Context Protocol (MCP), a standard way for AI tools to reach outside services. According to Walmart, the gateway keeps helpers away from a customer's shopping history and personal details. The helpers can still find usual items, such as a favorite sourdough loaf or a certain brand of milk, without seeing the rest of the purchase history.
Walmart's rules for these helpers are strict. A helper must not do anything the shopper did not intend, and it cannot change a customer's payment method. It may only see the information it needs for the job. Walmart says it will block helpers that break these rules. Sam's Club is also planned to get the same service.
This move is part of a longer push. In May 2025, Walmart said it was building AI tools made for retail tasks, using its own data and large language models (the kind of AI behind chatbots). Later that year, Reuters reported that Walmart planned four "super agents" to replace several separate AI tools, and that it wanted half of its total sales to come from online shopping within five years. Walmart's shopping assistant is called Sparky, and it is built into the Walmart app.
Amazon has taken a different route. It has blocked shopping helpers from Perplexity and Meta. Amazon sued Perplexity in November 2025, claiming it had secretly reached into private customer accounts through its Comet browser. In March 2026, a court order stopped Perplexity's shopping helper from using Amazon, and Amazon won the case. In September 2026, Amazon also launched a new AI service for third-party sellers.
On October 6, 2026, Quartz reported that Meta, Walmart and Stripe had launched an open standard that lets businesses check whether they are talking to an AI bot or a real person.
The broader context here is two different strategies. Amazon keeps outside helpers out. Walmart is opening a controlled door, where the helper signs in through a gateway, stays within a set budget, and follows written rules. Both routes can co-exist, and the new identity standard suggests retailers will need a way to tell helpers from people either way.
In my view, the hard questions are practical. An approval step only helps if the purchase is shown clearly, and if the helper cannot be tricked by hidden instructions on a web page. The privacy limits will also be tested in daily use, and Walmart will need to show how it spots helpers that break the rules.
The upside, as I read it, is easy to picture. A shopper could hand the weekly groceries to a helper with a fixed budget, a sign-off on each purchase and an off switch, without giving up a card number or full shopping history. If the safeguards work in practice, that could make everyday checkout a lot less of a chore.
