Walmart Inc.

One of the top retail media networks globally, second only to Amazon Advertising in U.S. retail media scale, with unmatched brick-and-mortar data integration

Walmart Inc. is the world's largest retailer and a formidable force in the retail media and AdTech ecosystem through its advertising platform, Walmart Connect. Leveraging first-party purchase data from hundreds of millions of annual shoppers, Walmart Connect enables brands and sellers to reach highly relevant audiences at every stage of the purchase journey — from awareness to conversion — across Walmart.com, the Walmart app, in-store screens, and off-site channels including social and programmatic display. The platform's unique strength lies in its ability to close the loop between ad exposure and actual purchase behavior, offering advertisers deterministic measurement that few other media networks can match. Walmart Connect offers a suite of advertising solutions including sponsored search ads, display advertising, video, and in-store digital media. Brands can leverage Walmart's rich shopper data for precise audience targeting, and the platform provides robust analytics and attribution tools to measure campaign effectiveness. Walmart has also expanded its off-site capabilities, allowing advertisers to reach Walmart shoppers across the broader web using Walmart's proprietary data signals. As retail media networks have become one of the fastest-growing segments in digital advertising, Walmart Connect stands as a top-tier competitor to Amazon Advertising and Kroger Precision Marketing. With its scale — over 4,600 U.S. stores, a growing e-commerce business, and a customer base that spans virtually every demographic — Walmart Connect offers advertisers a compelling combination of reach, data depth, and closed-loop measurement. The platform is particularly significant for CPG brands, endemic retail advertisers, and marketplace sellers seeking to influence purchase decisions at the point of sale.
