Walmart Opens Its Online Shop to AI Agents While Amazon Blocks Automated Purchases

Imagine waking up to find your fridge already restocked, your household supplies ordered, and your weekly shop completed — all while you slept. No clicking, no queuing, no forgotten items. That’s the promise behind what Walmart announced on 21 October 2026: a formal system letting approved AI agents browse its shelves, fill a basket, and check out on a customer’s behalf.

The American retail giant calls it Agent Gateway. And it marks one of the clearest moves yet by a major retailer to open its doors to the growing world of agentic shopping — software that doesn’t just suggest products but actually buys them for you.

What Walmart Is Actually Building

Agent Gateway is the infrastructure side of the announcement: a controlled channel through which approved third-party AI agents can search Walmart’s inventory and complete purchases. The consumer-facing piece, called Agent Profiles, is scheduled to begin rolling out in November 2026.

Each AI agent a customer chooses to use gets its own dedicated profile. That means purchases made by an agent show up separately from a customer’s own orders — a small but meaningful detail. If something goes wrong, or if you simply want to check what the agent bought last Tuesday, you don’t have to sift through your entire order history to find it.

Control sits firmly with the customer. By default, every purchase requires approval before it goes through. Customers who trust their agent enough can instead set a spending limit — Walmart’s examples are $50, $100, and $200 (around £40, £80, and £160 at current rates) — within which the agent can buy without asking first. But Walmart reserves the right to request additional approval even when a purchase falls within that limit. And critically, Walmart says customers’ payment details are never handed over to the AI agent itself.

Any agent that breaks Walmart’s terms can be blocked from the site entirely.

Amazon Is Taking the Opposite Approach

Not every retailer is rolling out the welcome mat. Amazon has reportedly been moving in the opposite direction, blocking AI agents — including Meta’s Muse shopping agent — from browsing or purchasing through its retail site, according to a report by TechCrunch in October 2026.

Amazon’s position reflects real concerns. Automated agents accessing retail sites at scale raise questions about scraping, unauthorised account access, transaction security, and whether customers genuinely understand what they’re authorising. A human clicking “buy now” is one thing. Software doing it on their behalf — possibly misreading a product description or selecting the wrong variant — is another.

The contrast between the two companies is striking. Walmart is betting that a structured, permission-based system can make agentic shopping safe enough for mainstream use. Amazon, for now, appears to disagree.

The Bigger Picture

Agentic shopping is still early. But the direction of travel is clear.

AI assistants are already capable of searching the web, comparing prices, and drafting purchase decisions. The next step — actually completing the transaction — has been the sticking point, partly because retailers haven’t built the infrastructure to handle it safely, and partly because the liability questions are genuinely complicated. If an agent buys the wrong thing, who’s responsible? The customer? The AI company? The retailer?

Walmart’s approach doesn’t fully answer those questions, but it does try to contain the risk. Spending caps and approval prompts add friction back into a process that’s supposed to reduce it. Critics point out that caps alone don’t prevent an agent from making the right purchase at the wrong time, ordering a substitution you didn’t want, or triggering a recurring order you didn’t intend.

Still, Walmart’s move is likely to attract AI companies looking for a retail partner willing to work with them, and shoppers curious about automating the dull parts of their weekly routine.

What the Announcement Doesn’t Cover

Worth being clear about what Walmart hasn’t said. The Agent Gateway announcement relates to Walmart’s US operation. No UK launch date, UK-specific terms, or equivalent GBP spending limits have been announced. Walmart does not operate a major UK supermarket or general merchandise retail network comparable to its American business, so British consumers won’t be logging into walmart.com any time soon.

Any future rollout in the UK would need to grapple with UK GDPR, the Data Protection Act 2018, the Consumer Rights Act 2015, and payment-services rules — above all around consent, liability for unauthorised purchases, and the right to refunds. Those aren’t insurmountable hurdles, but they’d require careful implementation.

The broader shift, though — retailers deciding how to handle AI agents trying to shop on customers’ behalf — is happening now, and it’ll shape how online retail works for everyone.

What This Means for Kent Residents

Walmart’s Agent Gateway is a US launch, and Kent shoppers won’t be using it directly. But the same questions about AI agents, automated purchasing, and retailer access policies will eventually reach UK platforms — and if you already use any AI shopping tool, it’s worth checking whether it has purchase approval enabled, a spending limit set, and a clear returns process in place. UK consumer rights under the Consumer Rights Act 2015 still apply to online purchases, but how those rights interact with agent-led transactions remains an open question that regulators and retailers will need to address.
