AI Shopping Agents Could Threaten Amazon and Walmart Ad Sales

Reuters reports that artificial intelligence shopping agents could undercut the advertising businesses that have become a major source of profit for Amazon and Walmart, as consumers increasingly let AI tools find and compare products rather than browsing retailer websites directly, according to the Reuters report.

The concern centers on a shift in how people shop online. When a shopper types a request into an AI agent and the agent returns a single recommended product, the retailer's own search results page, and the sponsored listings sold against it, never get a chance to load.

What did Reuters report about AI shopping agents and retail ads

Reuters frames the risk as structural rather than hypothetical: if AI agents increasingly act as the point of purchase, the on-site search and browsing behavior that retail advertising is built around could shrink. The report ties this dynamic directly to Amazon and Walmart, the two companies most associated with turning e-commerce search results into paid media.

How do Amazon and Walmart make money from advertising

Both companies have built what the industry calls retail media networks, selling brands the ability to place sponsored products at the top of search results and category pages. That business model depends on shoppers typing search terms into the retailer's own site or app, scrolling through options, and clicking on paid placements before buying. The more steps in that process, the more opportunities a retailer has to sell ad space along the way.

Why could AI agents change how shoppers find products

An AI shopping agent compresses that multi-step process into a single exchange. A shopper describes what is needed, and the agent returns a recommendation, sometimes with a short list of alternatives, drawn from its own reasoning about price, reviews, and specifications rather than from a retailer's paid search auction. If that becomes a common shopping pattern, the sponsored listings that currently appear on Amazon and Walmart search pages have fewer eyeballs to reach, which is the core tension Reuters describes.

What are Amazon and Walmart saying publicly

The available source material does not include direct comment from Amazon or Walmart addressing this specific risk, and no statement from either company is quoted in the Reuters report as summarized. Investors and analysts, rather than the companies themselves, appear to be the ones framing AI shopping agents as a threat to retail media revenue, based on the report's description of the dynamic.

What should shoppers and investors watch next

• Whether Amazon and Walmart disclose retail media or advertising revenue trends in upcoming earnings calls that reference AI-driven shopping behavior.
• Whether either company builds its own AI shopping assistant designed to keep sponsored placements inside the recommendation flow rather than bypassing it.
• Whether AI agents from outside developers, rather than from the retailers themselves, gain enough adoption to materially shift how often shoppers land on a retailer's own search page.
• Whether brands that currently pay for sponsored placement on Amazon or Walmart begin shifting marketing budgets toward optimizing how their products appear inside AI agent recommendations instead.

None of those outcomes is confirmed in the current reporting. The Reuters account describes a potential threat tied to a structural shift in shopping behavior, not a disclosed drop in revenue at either company. Readers should treat the claim as an emerging industry concern rather than a settled financial outcome until Amazon or Walmart address it directly or report figures reflecting the change.

Why has retail media advertising mattered so much to Amazon and Walmart

Reuters frames retail media as a profit center that both companies have leaned on heavily, built on top of their existing e-commerce traffic rather than requiring new customer acquisition. The report describes the business as dependent on shoppers continuing to search and browse directly on Amazon or Walmart's own platforms, since that behavior is what generates the page views sponsored listings are sold against. The structural risk Reuters identifies is not that AI agents eliminate shopping altogether, but that they remove the browsing step that currently produces ad inventory. If a shopper's interaction with a retailer shrinks to a single transaction completed through a third-party AI agent, the retailer loses the repeated search queries and category-page views that have made retail media attractive to sell against, according to the report's description of the dynamic facing Amazon and Walmart.
