Walmart Inc.

One of the top three retail media networks in the U.S., competing directly with Amazon Advertising and Kroger Precision Marketing, with unmatched physical retail reach and growing CTV capabilities.

Walmart Inc. is the world's largest retailer, operating thousands of stores globally and a growing e-commerce ecosystem. Through its advertising arm, Walmart Connect, the company has established itself as a major force in retail media, offering brands and agencies the ability to reach Walmart's massive customer base—over 150 million weekly shoppers in the U.S.—across on-site, off-site, and in-store channels. Walmart Connect provides sponsored search, display advertising, and video ad formats, all powered by Walmart's first-party purchase data, enabling highly precise audience targeting and closed-loop measurement. In the AdTech ecosystem, Walmart Connect competes directly with Amazon Advertising and other retail media networks, positioning itself as a premium alternative with unmatched reach in physical retail. The platform leverages Walmart's omnichannel footprint—including Walmart.com, the Walmart app, Sam's Club, and in-store digital screens—to offer advertisers a full-funnel solution. Walmart has also made strategic investments in AdTech infrastructure, including its acquisition of smart TV maker Vizio in 2024, which significantly expands its connected TV (CTV) and streaming advertising capabilities. Walmart Connect's value to advertisers lies in its unique combination of scale, first-party data richness, and the ability to connect ad exposure directly to in-store and online purchase outcomes. As retail media continues to grow as one of the fastest-expanding segments of digital advertising, Walmart is investing heavily in self-serve tools, programmatic capabilities, and measurement solutions to attract brands of all sizes—from large CPG companies to emerging direct-to-consumer brands.
