Walmart AI Agents: Retailer Opens Checkout as Amazon Fights Bots

What Walmart announced

Walmart is betting that a growing share of online shopping will be done by software acting for people. On Wednesday, October 21, the retailer unveiled a set of tools that let approved AI assistants search its catalog and complete purchases on customers' behalf, with limits on what those assistants can spend 18. The two centerpieces are Agent Profiles and the Walmart Agent Gateway. Both work across Walmart and Sam's Club, and the company named OpenAI's ChatGPT, Google's Gemini and Meta's Muse as supported assistants 247.

Agent Profiles give each authorized assistant its own identity inside a shopper's account. Customers can view that agent's orders separately from their own and choose between two settings: approve every purchase, or let the agent buy freely up to a spending cap. They can also cut off its access at any time 578.

The timing is described slightly differently across outlets. PYMNTS cites a November launch, while others say "next month" 89. Those likely point to the same rollout window. PYMNTS also describes three new tools where most reports focus on two 8.

The Agent Gateway is the technical connection. It is an MCP server built on the Model Context Protocol, which Anthropic originally developed, and it lets approved agents plug directly into Walmart's inventory and checkout 34. According to Walmart:

• Agents cannot see payment card numbers 27.
• Agents do not receive a customer's personal information or purchase history directly 4.
• Walmart can tell agent-led transactions apart from ones the customer makes personally 4.
• No Walmart+ membership is required 2.
• Standard return guarantees still apply 6.

The rules of the road

Walmart paired the tools with published terms that any agent must follow. The headline principle is that "agents must not take actions beyond what the shopper intends." Agents also cannot change a customer's payment method and may access only the information needed for their task 910. Walmart says it will block agents that break these rules 710.

The company was careful about how it framed the launch. In its release, Walmart said shopping with an agent "won't be for everyone, and it doesn't have to be," and positioned its goal as being the most trusted option for those who choose it 8.

That framing matters because consumer appetite remains thin. One analyst figure puts the share of shoppers comfortable handing purchases to AI at just 16% 2.

Why it matters: the Amazon contrast

Nearly every report frames the move against Amazon, which has taken the opposite approach. Amazon has blocked third-party shopping agents, including Perplexity's and Meta's Muse. It reportedly cited security and customer-experience concerns in shutting out Muse 2610. TechCrunch notes that travel and booking sites have also locked agents out entirely, which makes Walmart something of an outlier 1.

The legal fight around Amazon's stance has been volatile. Amazon sued Perplexity in November, alleging the startup concealed its agents to keep scraping the site. A federal judge then granted a temporary injunction, finding "strong evidence" that Perplexity's Comet browser accessed Amazon without authorization 11. Perplexity called the suit a "bully tactic" 11.

The Ninth Circuit later overturned that injunction. It reasoned that because Comet acts only when a user instructs it, it is effectively the user, not Perplexity, who is accessing Amazon's servers 12. That ruling weakens the legal footing for platforms that want to wall agents off.

Walmart's longer runway

The announcement builds on earlier work. Walmart introduced its Sparky assistant in June 2025 and laid out a four-"super-agent" framework that same year. It has since embedded Sparky inside ChatGPT 9. It had also already partnered with Meta's Muse and offered integrations with major AI apps before this rollout 1.

Our read

Walmart is treating agentic commerce as a channel to shape rather than a threat to repel. The bet is that whoever sets the terms for agents will get the traffic as these tools mature. Creati.ai makes the point directly: control over checkout could decide which retailers are easiest for shopping assistants to use 3.

The appeals ruling strengthens Walmart's hand. If courts treat user-directed agents as the users themselves, blanket blocking becomes harder to sustain 12. In that scenario, sanctioned gateways with visible guardrails look less like a concession and more like the practical model.

The open question is demand. With most shoppers still wary 2, Walmart's spending caps and revocation controls are as much a tool for building trust as a technical feature. Whether they convince people to let a bot fill their cart is still unproven.
