Walmart opens its checkout to AI shopping agents as Amazon shuts them out

Walmart said this week that it will let outside artificial-intelligence shopping agents place orders directly through Walmart.com and Sam's Club, a move that puts the country's largest retailer by revenue on the opposite side of a fast-moving industry split from Amazon, which has spent the past month blocking the same kind of software.

In a post on its corporate newsroom dated Oct. 21, the company introduced three pieces of what it calls an agent-shopping framework: a developer tool called the Walmart Agent Gateway, consumer-facing "Agent Profiles" with spending controls, and a set of terms governing what automated shoppers can and cannot do on its sites.

How the system is supposed to work

Today, Walmart said, an AI agent shopping on a customer's behalf typically signs into that person's own account, so its purchases and the customer's purchases land in the same order history with no way to tell them apart. Agent Profiles are meant to fix that: each authorized agent gets its own profile nested inside the customer's account, with purchases tracked separately. Customers can require their approval for every single purchase or let an agent spend freely up to a limit they set — Walmart's own examples were $50, $100 and $200 — and they can revoke an agent's access or delete its profile at any time. The company compared the arrangement to adding an authorized user to a credit card. Agent Profiles are expected to roll out, in Walmart's words, "in the next month."

The Agent Gateway is the plumbing underneath that system. Rather than having an agent click through Walmart's website the way a person would — a method Walmart described as slow and error-prone — the gateway gives software a more direct, structured channel using the Model Context Protocol, the open standard for connecting AI applications to outside data and tools that Anthropic released in late 2024 and that has since been adopted broadly across the industry. The gateway is launching as an invitation-only beta for companies and developers, not the general public. Under the posted terms, agents cannot receive a customer's payment-card details or change payment methods, may access only the information a given task requires, and face being blocked from Walmart's sites altogether if they violate the rules. Walmart's ordinary returns process applies even to purchases an agent gets wrong.

A retailer betting on scale

Walmart is not a marginal player experimenting at the edges of its business. The company's most recent annual report filed with the Securities and Exchange Commission put total revenue for the fiscal year ended Jan. 31, 2026, at $713.2 billion, the vast majority of it net sales. Opening that volume of commerce to automated buyers — even gradually, even behind a beta wall — is a meaningfully different posture than treating AI agents as a threat to be fenced out. Walmart framed the decision explicitly as an attempt to get ahead of a shift it sees as inevitable.

Shopping with an agent won't be for everyone, and it doesn't have to be.

That line, from Walmart's own announcement, captures the company's calculated, opt-in framing: customers who want nothing to do with agentic shopping can ignore the feature entirely, while those who do use agents such as Walmart's in-house assistant Sparky, OpenAI's ChatGPT, Google's Gemini or Meta's Muse get a defined, permissioned lane rather than an open door.

A split from Amazon

The contrast with Amazon is pointed. On Sept. 20, Amazon began blocking Meta's newly launched Muse shopping agent from completing purchases on Amazon.com, according to Adweek and other outlets that covered the standoff. Amazon said it had never authorized Muse to operate on its marketplace, that the agent did not identify itself while browsing, and that it appeared to capture and store customers' Amazon credentials — characterizations Meta has disputed, saying Muse never sees raw passwords or payment information and stores credentials only in encrypted form. Meta declined Amazon's request to pull the bot from its product. The dispute remains unresolved, and it is just one example of a broader pattern: a number of travel and booking sites have locked AI agents out of their platforms entirely rather than build the kind of permissioned access Walmart is now rolling out, as TechCrunch noted in its report on Walmart's announcement.

Walmart's approach is also a continuation of moves it had already made. The retailer has previously opened integrations with ChatGPT and Gemini and has promoted Sparky as a conversational shopping tool inside its own app. The Agent Gateway and Agent Profiles formalize that strategy into a system with explicit financial guardrails, something the earlier integrations largely lacked.

Who is affected, and what comes next

For now, the practical effect is limited. The Agent Gateway beta is restricted to companies and developers Walmart has invited, not ordinary shoppers, and Agent Profiles have not yet launched for consumers. Walmart has not disclosed which companies are in the beta, how granular its rate limits or category restrictions will be, or how it will detect and enforce violations of its agent terms once the system is live more broadly. It is also unclear whether the spending-limit examples of $50, $100 and $200 apply per order, per day or over some longer period — details that will matter once real money is moving through the system at scale.

• Walmart announced the framework Oct. 21, 2026; Agent Profiles are expected within about a month.
• Example customer-set spending limits for agents: $50, $100 or $200 per the company's own illustrations.
• Walmart's fiscal 2026 revenue, per its SEC filing, was $713.2 billion.
• Amazon began blocking Meta's Muse agent on Sept. 20, 2026, a move still unresolved between the two companies.

The near-term question for consumers is less about today's limited beta and more about where the industry is heading. With Walmart and Amazon — the two largest forces in American retail — now pursuing opposite strategies toward the same technology, shoppers who rely on AI assistants to do their buying may increasingly find that which retailer welcomes their agent, and under what rules, varies from one store to the next.
