Amazon is still slamming the door on the same bots.*\n\nWalmart said on October 21 that it's building a direct lane for AI agents to shop and check out on its own platform, no human clicking required. The company calls it the Walmart Agent Gateway, and it runs on Anthropic's open Model Context Protocol, the same standard that lets AI tools talk to outside systems without custom code for every pairing. Full rollout is targeted for late November, timed to land right before the busiest shopping weeks of the year.\n\nHere's the mechanic that matters: every approved agent gets its own Agent Profile inside a customer's account, separate from the customer's own login. According to reporting from TechCrunch and Axios, agents never see card details and can't add or change a payment method. Customers pick one of two modes. Either they approve every single purchase an agent wants to make, or they hand the agent a spending ceiling, Walmart has floated examples like $50, $100 or $200, and let it buy within that limit on its own. Walmart says it can still ask for extra approval even inside that ceiling if something looks off.\n\nThe Gateway itself is an MCP server that routes agent requests through Sparky, Walmart's in-house shopping assistant, rather than making agents scrape the website like a browser. Right now it's an invite-only beta. The company has said it's working directly with OpenAI and Google so ChatGPT and Gemini can surface Walmart products and carry a shopper through checkout without leaving the chat window.\n\nAmazon has gone the other direction, and the contrast tells you more than the launch itself. The company has blocked a growing list of AI shopping agents from transacting on its site, including Meta's Muse, according to Axios. It went further with Perplexity: Amazon won a federal injunction in March blocking Perplexity's Comet browser agent from shopping on Amazon on the customer's behalf, only for the Ninth Circuit to vacate that injunction on August 4. The legal fight signals how seriously Amazon takes the threat of losing the checkout moment to someone else's assistant. Amazon's own answer is Rufus, a shopping assistant it controls end to end, inside its own walls.\n\n[Amazon is in talks to buy AI startup Decart for about $7 billion](https://startupfortune.com/amazon-is-in-talks-to-buy-ai-startup-decart-for-about-7-billion/)\n\nDecart, maker of the real-time video model Lucy and the robotics-training tool Oasis, was valued at $4 billion in May. Amazon's reported offer would nearly double that in six months. - [Amazon acquires AI startup Decart for billions](https://startupfortune.com/amazon-is-in-talks-to-buy-ai-startup-decart-for-about-7-billion/) - [real time video editing AI technology acquisition](https://startupfortune.com/amazon-is-in-talks-to-buy-ai-startup-decart-for-about-7-billion/)\n\nThat split is not an accident of two companies moving at different speeds. It's two different bets on where the money sits once AI agents start doing the shopping. Walmart is betting that free distribution through ChatGPT and Gemini, platforms with hundreds of millions of users Walmart didn't have to acquire, is worth opening the gate and accepting some loss of control over the shopping experience. Amazon is betting that owning the entire path from search to cart to payment is worth shutting outside agents out, even at the cost of friction when a customer would rather ask an AI assistant than click through Amazon's own app.\n\nFrankly, Walmart's version is the one that actually tests whether agentic commerce is real money or just a demo. Letting ChatGPT recommend a product is one thing. Letting it hold a spending limit against your account and actually complete the purchase, with a login of its own and no retry loop for a human, is a different level of trust, and it's the first time a retailer this size has written the terms of service for it rather than just talking about the idea at a conference.\n\nFor founders building shopping agents or AI commerce tools, this is the first real spec to build against. A $50 or $100 default ceiling, a separate login per agent, mandatory approval unless a customer opts out, these aren't abstractions anymore, they're terms Walmart will actually enforce starting next month. Agents that can't operate cleanly inside those guardrails won't get an invite to the beta, and agents that can just got their first real purchasing rail into a major retailer heading into the holidays.\n\n**Also read:** [Three Men Charged in $129 Million AI Voice Cloning Fraud Scheme](https://startupfortune.com/three-men-charged-in-129-million-ai-voice-cloning-fraud-scheme/) • [Meta Weighs Cutting 16,000 Jobs to Fund Its AI Infrastructure Bet](https://startupfortune.com/meta-weighs-cutting-16000-jobs-to-fund-its-ai-infrastructure-bet/) • [Five9 agrees to buy Level AI for $325 million in cash](https://startupfortune.com/five9-agrees-to-buy-level-ai-for-325-million-in-cash/)\n\n*This article is posted in [AI News](https://startupfortune.com/category/ai/), check it out for more related stories.*\n\n## Join the discussion\n\n[Open in the community →](https://startupfortune.com/community/)\n\nAlmost there.
