Walmart Inc.

One of the top retail media networks in the U.S., competing with Amazon Advertising and Kroger Precision Marketing, backed by the world's largest retailer's first-party data and store footprint.

Walmart Inc. operates Walmart Connect, a powerful retail media network that leverages the company's position as the world's largest retailer to offer brands and advertisers unparalleled access to millions of shoppers. Through on-site sponsored search, display advertising, and off-site audience targeting, Walmart Connect enables advertisers to reach consumers at every stage of the purchase journey — from discovery to conversion — using Walmart's first-party purchase data. Walmart Connect has rapidly grown into one of the most significant retail media networks in the United States, competing directly with Amazon Advertising and other major retail media players. The platform provides closed-loop measurement, allowing advertisers to directly tie ad spend to in-store and online sales outcomes. Walmart's scale — with over 4,600 U.S. stores and a growing e-commerce presence — gives it a unique data advantage rooted in both online and offline purchase behavior. Beyond its core retail media offerings, Walmart has expanded its AdTech capabilities through strategic investments and acquisitions, including its acquisition of Vizio to bolster connected TV (CTV) advertising capabilities and first-party data reach. Walmart Connect serves a broad range of advertisers, from large CPG brands to emerging direct-to-consumer companies, making it a critical platform in the modern omnichannel advertising landscape.
