Walmart Inc.

One of the top retail media networks in the US, second only to Amazon Advertising in retail media scale, with a rapidly growing advertising business powered by first-party shopper data

Walmart Inc. is the world's largest retailer, operating thousands of stores globally and serving hundreds of millions of customers. Through its advertising division, Walmart Connect, the company has built a powerful retail media network that enables brands and sellers to reach Walmart's massive, purchase-intent-driven audience across digital and physical touchpoints. Walmart Connect offers sponsored search, display advertising, in-store activations, and closed-loop measurement capabilities that tie ad exposure directly to purchase outcomes — a significant differentiator in the advertising landscape. Walmart Connect has rapidly grown into one of the top retail media networks in the United States, competing directly with Amazon Advertising and Kroger Precision Marketing. The platform leverages Walmart's first-party transaction data from both its e-commerce properties and physical stores, providing advertisers with rich audience insights and precise targeting. Walmart has also expanded its capabilities through strategic acquisitions, including the purchase of Vizio, which adds connected TV (CTV) and streaming advertising inventory to its media offering. In the broader AdTech ecosystem, Walmart represents the convergence of retail and media, a trend often called 'retail media.' Its scale — encompassing Walmart.com, the Walmart app, Sam's Club, and in-store digital screens — gives advertisers unparalleled reach across the full purchase funnel. Walmart Connect's self-serve and managed-service options make it accessible to both large CPG brands and smaller advertisers, positioning Walmart as a formidable and growing force in digital advertising.
