Walmart Welcomes AI Shopping Agents as Amazon Tightens Access to E-Commerce

Walmart will allow AI agents to shop on its website for customers beginning next month, putting the retailer among the first major U.S. merchants to formally welcome automated purchasing. The company says agents must follow Walmart’s rules while searching for products, assembling carts and completing transactions on a customer’s behalf.

The move places Walmart at the center of a fight over who controls AI-mediated shopping. Its approach gives software a sanctioned route into the retailer’s commerce systems, while rival Amazon has restricted outside agents from making purchases. The contrast turns a technical access decision into a strategic bet on where consumers will begin their shopping journeys.

Walmart’s Agent Gateway is designed to manage transactions between the retailer and external AI agents. The system gives Walmart a controlled way to authenticate activity, apply shopping rules and preserve oversight as software interacts with its catalog, cart and checkout functions.

That structure matters because autonomous shopping introduces problems that ordinary web traffic does not. Agents can place orders quickly, compare products at scale and act on instructions without a person clicking through every step. Walmart’s framework lets the company participate in that process while retaining a role in pricing, fulfillment, customer accounts and transaction governance. The retailer’s broader agentic strategy also includes Sparky, its own shopping assistant, and an effort to connect AI-driven commerce with Walmart Connect’s retail advertising business.

Amazon has blocked or limited third-party AI agents from shopping on its site, creating the sharpest competitive contrast in the announcement. Coverage from CNBC, The Information and Yahoo Finance frames Amazon’s decision as a strategic dilemma: protect control over its customer relationship and infrastructure, or open the door to agents that could redirect shopping behavior.

Meta’s Muse illustrates the immediate friction. The agent has been unable to shop at Amazon, and NBC News also reported that it cannot shop at Walmart through the same route. Walmart’s new gateway changes that equation by offering a supported path for agents, even as access remains subject to the retailer’s conditions. The split gives developers a clear choice between a merchant that is building for agent access and one that is tightening its perimeter.

Walmart’s strategy is an attempt to capture demand even when a human shopper is no longer the primary interface. An agent can receive a request such as replenishing household goods, compare eligible products and submit an order, leaving Walmart to compete for selection, price, delivery and service inside the agent’s workflow.

That arrangement changes the value of visibility. Product descriptions, availability, fulfillment speed and pricing become inputs an agent evaluates on a customer’s behalf. Walmart Connect also gains a new commercial question: how advertising works when software, rather than a person, filters recommendations and decides which products enter a cart. The retailer’s willingness to support agents gives it a chance to shape those rules instead of waiting for outside systems to define them.

Walmart’s invitation comes with conditions, and those conditions will determine how useful agentic shopping becomes. Customers need confidence that an agent is acting within their instructions, selecting the correct products and prices, and stopping before an unwanted purchase. Walmart needs safeguards against fraud, account abuse, inaccurate orders and automated activity that strains its systems.

A managed gateway addresses part of that challenge by creating an official channel rather than forcing agents to imitate human browsing. The arrangement also gives Walmart more control over identity, permissions and transaction records. At the same time, the retailer’s own Sparky initiative means Walmart is developing both the merchant infrastructure and a first-party assistant, a combination that can strengthen its control over the customer experience.

Walmart’s rollout will test whether customers trust agents with routine purchases and whether developers can build useful shopping experiences within the retailer’s rules. Early adoption will depend on the quality of product matching, delivery choices, returns and approval controls as much as on the novelty of automated checkout.

The competitive stakes extend beyond Walmart and Amazon. Google, Meta and other AI companies need reliable merchant access if their assistants are to become purchasing tools rather than recommendation engines. Retailers, meanwhile, must decide whether agents bring incremental sales or weaken their direct relationship with shoppers. Walmart has chosen access first, with guardrails attached. The results will help determine whether agentic commerce becomes a retail channel or remains a carefully managed experiment.
