- Walmart launched Agent Gateway, a new MCP server letting approved AI agents search its inventory and complete purchases on a shopper’s behalf, the company announced on October 21, 2026.
- The move contrasts with Amazon, which has begun blocking AI agents from making purchases on its site, as well as several travel and booking sites that lock agents out entirely.
- Walmart’s Agent Profiles, rolling out next month, let customers authorize each AI agent with its own account profile and separate its purchases from the customer’s own.
- Shoppers can require approval for every agent transaction or set a spending limit for pre-authorized purchases, similar to controls for an authorized user on a credit card.
What Happened
Walmart president and CEO John Furner announced the retailer’s Agent Gateway and related agentic-commerce tools at the Masters of Scale Summit in San Francisco, TechCrunch reported on October 21, 2026, extending the rollout to both Walmart and Sam’s Club.
Why It Matters
The announcement deepens Walmart’s agentic-commerce bet after it dropped OpenAI’s Instant Checkout following weak conversion rates and previously partnered with Meta’s Muse and integrated ChatGPT and Gemini, while rival Amazon moves in the opposite direction by restricting agent purchases.
Technical Details
Agent Gateway runs on the model context protocol, originally created by Anthropic, letting external agents connect to Walmart’s inventory and transact without the agent’s user sharing personal data or purchase history directly with the agent. Walmart said agent purchases will be tracked separately from a customer’s own direct purchases.
Who’s Affected
Shoppers using AI agents from providers like ChatGPT and Gemini gain a retailer willing to transact with them, while Amazon shoppers using agents lose that option on Amazon’s own site. Agent developers gain a new MCP-based integration surface to build against.
What’s Next
Agent Profiles are scheduled to roll out next month, giving customers per-agent authorization and spending controls; Walmart has not said when Agent Gateway itself will be generally available beyond the initial rollout.
