Walmart is expanding into agentic commerce with an Agent Gateway that connects AI assistants, including OpenAI’s ChatGPT, Google’s Gemini and Meta’s Muse, with Walmart and Sam’s Club systems. The retailer plans to introduce Agent Profiles within a month, allowing customers to register each AI assistant separately, review its purchases apart from their own orders, require approval for every transaction or permit purchases within spending limits of US$50, US$100 or US$200. Customers can remove an agent profile at any time. Walmart’s approach contrasts with Amazon, which blocks outside shopping agents while promoting its own AI shopping tools. The initiative builds on Walmart’s wider AI strategy, including Sparky and prior integrations, as technology companies invest in agents that can complete multi-step online tasks.
