Amazon

Third-largest digital advertising platform globally and the dominant retail media network, leveraging first-party commerce data at massive scale

Amazon.com, Inc., founded in 1994 and headquartered in Seattle, Washington, began as an online bookstore before evolving into the world's largest e-commerce marketplace and a leading cloud computing provider through Amazon Web Services (AWS). Today, Amazon operates across e-commerce, cloud infrastructure, digital streaming, artificial intelligence, and advertising, making it one of the most diversified and valuable technology companies on the planet. Amazon's advertising business, operating primarily under the Amazon Ads brand, has grown into the third-largest digital advertising platform globally, trailing only Google and Meta. Amazon Ads leverages unparalleled first-party purchase intent and behavioral data from hundreds of millions of active customers to offer highly targeted advertising solutions including Sponsored Products, Sponsored Brands, Sponsored Display, and the Amazon DSP (Demand-Side Platform). Advertisers benefit from closed-loop attribution, meaning they can directly measure how ad spend translates into purchases on and off Amazon's properties. In the AdTech ecosystem, Amazon holds a uniquely powerful position due to its ownership of the entire commerce funnel — from product discovery and purchase to fulfillment and post-purchase engagement. AWS also underpins a significant portion of the broader AdTech industry's infrastructure. Amazon's advertising revenue has surpassed $50 billion annually, reflecting its growing dominance as a retail media network and full-funnel advertising platform. Competitors include Google, Meta, The Trade Desk, and Walmart Connect, though Amazon's combination of retail data, owned media, and cloud infrastructure creates a formidable and largely unmatched competitive moat.
