Growing retail media network backed by one of the largest warehouse club retailers globally
Costco Advertising operates as the retail media division of Costco Wholesale Corporation, one of the world's largest warehouse club retailers. The advertising platform enables brands, suppliers, and agencies to reach Costco's highly valuable membership base through various advertising channels including in-warehouse displays, digital advertising on Costco.com, email marketing, and the Costco Connection magazine. Costco Advertising leverages the retailer's unique position with its affluent, loyal membership base of over 100 million cardholders to offer targeted advertising opportunities. As a retail media network, Costco Advertising provides brands with access to first-party data and closed-loop measurement capabilities, allowing advertisers to reach consumers at critical points in their shopping journey. The platform offers both endemic advertising (for brands sold at Costco) and increasingly non-endemic opportunities, competing in the rapidly growing retail media space alongside networks from Amazon, Walmart, Target, and other major retailers. Costco's advertising business benefits from the company's premium membership model and high member engagement, with the average Costco member visiting stores frequently and demonstrating strong purchasing power.
