Walmart launched Agent Gateway on October 21, 2026, letting AI assistants like ChatGPT and Gemini shop for customers, unlike Amazon.
What Happened
US retailer Walmart launched a system called Agent Gateway on Wednesday, October 21, 2026, that lets approved artificial intelligence (AI) assistants search its product catalogue and buy goods on behalf of shoppers. According to reports on the launch, assistants such as OpenAI's ChatGPT, Google's Gemini and Meta's Muse can connect directly with Walmart and Sam's Club systems through the gateway. The move puts Walmart on the opposite side from Amazon, which has sought to limit third-party AI shopping agents' access to its platform.
Key Facts
- Agent Gateway lets approved AI assistants search Walmart's catalogue and make purchases for customers.
- Assistants named in reports include OpenAI's ChatGPT, Google's Gemini and Meta's Muse.
- The system covers both Walmart and its warehouse club, Sam's Club.
- It is built on the Model Context Protocol (MCP), an open standard for connecting AI assistants to outside tools, first developed by Anthropic.
- A companion feature, Agent Profiles, is due next month: shoppers will be able to give each AI agent its own profile, set spending limits or require approval for every purchase, and withdraw access at any time.
- The tools are open to all Walmart account holders, without a paid Walmart+ membership.
- Mizuho analyst David Bellinger described AI-led shopping as "experimental" but said the tools instil confidence.
Why It Matters
An AI agent is software that does not just answer questions but takes actions for a user: comparing products, filling a cart, placing an order. For a shopper, that could mean asking an assistant to "reorder the usual groceries under a set budget" instead of browsing a website. For retailers, it raises a big strategic question: should they let these agents in, or keep them out?
Walmart has chosen to open the door, with controls. By building on an open standard rather than a closed system of its own, it makes it easier for many different AI assistants to connect. The planned Agent Profiles are its answer to the obvious worry about letting software spend money: spending caps, purchase-by-purchase approval and the ability to cut off an agent instantly. Amazon's approach has been to restrict outside agents, which keeps more control over the shopping experience and the customer relationship on its own platform. Which approach wins will shape how online retail works in the coming years.
For entrepreneurs, including those in India, the move matters because it signals where new business may grow. If big retailers open standard connections for AI agents, there is room for start-ups that build specialised shopping agents, tools that help sellers make their products easy for agents to find, and services that handle payments, security and fraud checks for agent-led purchases. The use of an open protocol lowers the barrier for smaller developers to plug in, rather than needing a separate deal with every retailer.
There are open questions too. Analysts call this kind of shopping experimental. It is not yet clear how many customers will trust an AI to buy for them, who is responsible when an agent buys the wrong thing, and how retailers will handle promotions and advertising when the "shopper" is software. Agent Profiles, with their spending controls, are not live yet, so the safeguards are still to be tested in practice.
| Walmart vs Amazon on AI shopping agents | Approach |
|---|---|
| Walmart | Opens a gateway for approved agents, built on an open standard |
| Amazon | Has sought to limit third-party AI shopping agents' access |
| Walmart's planned controls | Per-agent profiles, spending limits, approvals, revocable access |
Impact
Short-term: Walmart customers who use the named AI assistants can begin using them to search and shop at Walmart and Sam's Club. Developers of AI agents gain a large retailer to connect to through a common standard.
Long-term: If shoppers adopt agent-led buying, retailers may compete not only for human visitors but for the attention of AI assistants, changing how products are listed, priced and promoted. Pressure may grow on retailers that restrict agents to open up, or to build their own.
Who is affected: Walmart and Sam's Club customers; AI companies whose assistants connect to the gateway; sellers on Walmart's marketplace; start-ups building agent, payment and security tools; and rival retailers such as Amazon.
Key Takeaway
Walmart's Agent Gateway, launched on October 21, 2026, lets AI assistants such as ChatGPT and Gemini shop on customers' behalf, setting it apart from Amazon and opening a new field for developers of AI shopping tools.
