Two of the world’s biggest retailers have just placed opposite bets on the same technology. On 21 October 2026, Walmart announced it is opening its doors to AI shopping agents — rolling out Agent Profiles that let shoppers authorise individual agents with spending limits, plus a new Walmart Agent Gateway that connects ChatGPT, Google’s Gemini and Meta’s Muse directly to its checkouts. Amazon, meanwhile, is busy blocking those same agents. Here is what Walmart’s move means for you.
What did Walmart actually announce?
Walmart announced two things on Wednesday 21 October 2026: Agent Profiles, rolling out next month, and the Walmart Agent Gateway, a platform for AI assistants to connect directly with Walmart and Sam’s Club.
The announcement was made by Walmart CEO John Furner at the Masters of Scale Summit in San Francisco and reported the same day by Reuters. The tools will be available to all Walmart account holders and will not require a Walmart+ membership.
Wall Street took it seriously: Mizuho analyst David Bellinger said in a note that the tools instilled confidence in the “experimental” shopping process of agentic purchases, adding that “the momentum and buy-in from top management teams seems to be making this into a real thing.”
How do Walmart Agent Profiles work?
Agent Profiles give each AI agent you use its own profile inside your Walmart account, so its purchases stay separate from yours — and you set the spending rules.
Here is what the profiles do, based on Walmart’s announcement as reported by Reuters and EconoTimes:
- Authorise individual agents: you link each AI agent to a dedicated profile in your account — the profile is created the first time you use an agent through the Gateway.
- Track purchases separately: everything the agent buys is monitored apart from your own orders, so there is no mixing of agent orders with yours.
- Set spending rules: require approval for every transaction, or set a spending cap — Walmart listed $50, $100 and $200 as examples. Walmart describes the arrangement as being like adding an authorised user to a credit card.
- Approval is the default: customer approval is the default setting, and Walmart says it can request another confirmation even when a purchase falls below your authorised limit.
- Revoke anytime: you can monitor the agent’s activity and revoke its access at any time — and delete the profile whenever you like.
What is the Walmart Agent Gateway?
The Walmart Agent Gateway is a server built on the Model Context Protocol (MCP) that lets approved AI agents search Walmart’s inventory and buy on your behalf — without scraping the site like an unauthorised bot.
MCP is the open standard created by Anthropic that lets AI agents plug into outside tools and data. Through the Gateway, assistants such as OpenAI’s ChatGPT, Google’s Gemini and Meta’s Muse can connect directly with Walmart and Sam’s Club systems to search products and complete purchases, reports dig.watch.
A few practical details worth knowing:
- Agents see the same prices you do, with applicable offers and fees displayed before purchase.
- Agents do not get your wider purchase history — the Gateway lets an agent locate familiar items, like a preferred milk brand, without seeing everything you have ever bought.
- The Gateway starts as a developer beta: it is being tested first by companies and developers, with access described as limited and invitation-only.
What can Walmart’s AI agents NOT do?
Walmart drew hard lines: agents cannot see your payment-card details, cannot change your payment method, and get blocked if they break the rules.
Customers remain in control of purchases. Agents are barred from accessing payment-card data, and Walmart says it will block agents that breach its terms — non-compliant agents are simply cut off from the site. If an agent makes an unintended purchase, shoppers can use Walmart’s normal returns process.
This is the part that matters most. The fraud and liability questions — who pays when a bot buys the wrong thing — have been the biggest obstacle to agent commerce. Walmart’s answer is identity and limits: the agent is known, named in a profile, spending-capped, and revocable.
Why is Walmart welcoming AI agents while Amazon blocks them?
The split comes down to who owns the shopping journey: Amazon protects its ad-driven storefront; Walmart wants to meet shoppers wherever they already talk to AI.
Amazon has been actively limiting unauthorised AI agents on its platform — including blocking Meta’s Muse from shopping on Amazon.com, as we covered in our Amazon-blocked-Muse explainer. Amazon does run its own AI shopping tools, including Alexa for Shopping and its Buy for Me feature, which identifies itself to merchants and lets brands opt out.
Analysts point to a structural reason: Amazon earns large advertising revenue from sponsored listings that shoppers see while browsing, and an outside agent that browses and buys without viewing those pages weakens both the advertising and the data link. Blocking agents protects that model. Walmart, with a smaller share of online sales, gains reach by meeting shoppers inside ChatGPT, Gemini or Muse rather than trying to win them on its own site alone. (That motive reading is industry analysis, not Walmart’s stated rationale.)
The contrast goes beyond these two. Here is where the big names stand right now:
| Retailer | Stance on outside AI agents | How they do it |
|---|---|---|
| Walmart | Welcoming (from Nov 2026) | Agent Profiles + Agent Gateway (MCP); spending caps, separate order tracking, revocable |
| Amazon | Blocking third-party agents | Unauthorised agents cut off; pushes own Alexa for Shopping + Buy for Me |
| eBay | Banned (Jan 2026) | Outright ban on agent purchasing |
| Kohl’s, Tapestry | Browse-only | Agents may look, not buy |
| Chewy, Neiman Marcus | Blocking | Agent traffic blocked at the door |
And it is not just retailers: banks including Citi, JPMorgan and Bank of America have been locking agents out of financial accounts, as we reported in our piece on why banks are blocking AI agents. Walmart is betting that named, limited, revocable agent identities — the same ingredients the banks say are missing — can make agent commerce safe enough to scale.
What does it mean for shoppers?
In practice, it means you may soon be able to tell ChatGPT, Gemini or Muse to do your Walmart run — with you holding the kill switch.
Once Agent Profiles roll out in November, the realistic uses are the boring ones first: repeating grocery orders, restocking household staples, comparing prices across a list. The Gateway’s design — same prices, offers shown before purchase, no access to your card details — is built to make that feel routine rather than risky.
A few things to keep in mind before you hand an agent your shopping list:
- Start with per-transaction approval on. Let the agent prove itself on a few small orders before you switch to a spending cap.
- Set the cap low at first. A $50 or $100 limit keeps a misbehaving agent’s damage small while you learn its habits.
- Check the agent’s order history separately from yours — that is exactly what the separate tracking is for.
- Remember it is still early: the Gateway is in a limited beta, and the profiles roll out next month. Expect rough edges and regional differences in what agents can actually do.
Our take: retail just split into two camps
Walmart’s announcement is the clearest sign yet that the agent-commerce wars are really an identity fight — and the industry is splitting into “name your agents” versus “block your agents.”
Our read: Walmart is not being generous for fun. It is making the same calculation the banks made, but landing on the opposite answer. Where Citi and JPMorgan looked at unidentified agents with saved card credentials and said “no,” Walmart looked at the same risk and built the identity layer first: the agent gets a profile, a spending cap, a separate order trail, and no card data. That is precisely the audit trail banks and Amazon said was missing.
The honest caveat: we have not tested any of this hands-on — the profiles do not launch until November, and the Gateway is in a limited developer beta. Every detail above comes from Walmart’s 21 October announcement as reported by Reuters and corroborated by multiple outlets, verified on 22 October 2026. The real test will be the first month of live orders: whether shoppers trust the kill switch enough to actually use it.
