Amazon

Third-largest digital advertising platform globally and dominant leader in retail media networks, with unrivaled first-party purchase data and closed-loop measurement capabilities.

Amazon is a multinational technology conglomerate operating across e-commerce, cloud computing (AWS), digital streaming, artificial intelligence, and advertising. Its advertising business, Amazon Ads, has grown into the third-largest digital advertising platform globally, trailing only Google and Meta. Amazon Ads enables brands and agencies to reach consumers across Amazon's owned properties—including Amazon.com, Twitch, IMDb, and Fire TV—as well as across the broader open web through its demand-side platform (DSP). Amazon's advertising strength is rooted in its unmatched first-party purchase intent and behavioral data, derived from hundreds of millions of active customer accounts. This data allows advertisers to target audiences based on actual shopping behavior, purchase history, and product category interest—signals that are far more commercially actionable than most competitors can offer. Amazon Ads serves a wide range of advertisers, from small sellers on its marketplace to Fortune 500 brands running full-funnel campaigns. In the AdTech ecosystem, Amazon occupies a uniquely powerful position as both a retailer and a media owner, enabling closed-loop measurement that ties ad exposure directly to purchase outcomes. Its retail media network is the dominant player in the category, and its DSP competes directly with The Trade Desk and Google's DV360 for programmatic advertising budgets. Amazon's continued investment in streaming (Prime Video ads), connected TV, and AI-driven ad products positions it as a long-term disruptor across the entire digital advertising landscape.
