Amazon

Third-largest digital advertising platform globally and the dominant retail media network, commanding a significant and growing share of digital ad spend

Amazon is a multinational technology conglomerate operating across e-commerce, cloud computing (AWS), digital streaming, and artificial intelligence. Within the AdTech ecosystem, Amazon Advertising has emerged as the third-largest digital advertising platform globally, trailing only Google and Meta. Its unique advantage lies in its unparalleled first-party purchase intent data derived from hundreds of millions of active shoppers, enabling advertisers to reach consumers at every stage of the purchase funnel with exceptional precision. Amazon Advertising offers a comprehensive suite of ad products including Sponsored Products, Sponsored Brands, Sponsored Display, Amazon DSP (Demand-Side Platform), and streaming ad inventory through Prime Video and Freevee. These solutions serve both endemic advertisers (brands selling on Amazon) and non-endemic advertisers seeking to leverage Amazon's audience data off-platform. The Amazon DSP allows programmatic buying across Amazon-owned properties and third-party exchanges, making it a formidable player in the broader open web advertising market. Amazon's advertising business generates tens of billions of dollars annually and is one of the fastest-growing segments of the company. Its integration of retail media, streaming video, audio (via Amazon Music and Alexa), and programmatic display creates a closed-loop measurement ecosystem where advertisers can directly tie ad spend to sales outcomes. This retail media network model has made Amazon the defining blueprint for the broader retail media industry, influencing competitors like Walmart Connect, Target Roundel, and Kroger Precision Marketing.
