eBay

One of the top retail media networks globally, competing with Amazon Advertising and Walmart Connect, with a differentiated focus on unique and pre-owned goods audiences

eBay Inc. is one of the world's largest e-commerce marketplaces, connecting buyers and sellers across 190 markets globally. Founded in 1995, eBay operates a platform where individuals and businesses can buy and sell new and used goods across virtually every product category. With over 130 million active buyers and billions of live listings, eBay represents a massive commerce ecosystem with deep purchase-intent data. In the AdTech space, eBay has built out a significant retail media network known as eBay Ads, which allows brands, sellers, and advertisers to reach high-intent shoppers directly on the platform. eBay Ads offers promoted listings, display advertising, and offsite advertising products that leverage eBay's first-party shopper data. This positions eBay alongside Amazon Advertising and Walmart Connect as a major retail media player with unique access to transactional and behavioral data. eBay's advertising business has become an increasingly important revenue stream as the company seeks to diversify beyond transaction fees. The platform's focus on unique, pre-owned, and collectible items gives it a differentiated audience compared to other retail media networks, attracting advertisers in categories like automotive parts, collectibles, fashion, and electronics. eBay continues to invest in its advertising technology stack, including programmatic capabilities and audience targeting tools.
