The Third Advertising Giant

For most of the digital advertising era, the industry’s power structure was a duopoly: Google, which owned search intent, and Meta, which owned social attention. Everything else — every other platform, publisher, and media company — competed for the remaining fraction of a budget that flowed predominantly toward those two poles. The emergence of Amazon Advertising as a genuine peer to that duopoly is one of the most commercially significant developments in the media industry over the past five years, and the first quarter of 2026 confirmed its arrival with numbers that are difficult to contextualize without pausing.

Amazon’s advertising services revenue reached $17.2 billion in Q1 2026, up 22% year-on-year — growing faster, in percentage terms, than Meta’s advertising business in the same period. On a trailing twelve-month basis, the total crossed $70 billion. To place that figure in context: it is more than double Amazon’s advertising revenue from four years ago, it represents 39.8% of all U.S. retail media advertising spend, it rivals YouTube’s advertising business at scale, and it does so with conversion rates that digital advertising analysts consistently describe as substantially higher than any equivalent inventory on social or search platforms. “We continue working to be the best place for brands of all sizes to grow their businesses,” CEO Andy Jassy said on the earnings call.

The reason for those conversion rates is structural and is the foundation of everything Amazon Advertising has built. Users on Amazon are, by definition, in a shopping mindset — they are on the platform because they intend to buy something, not because they are passing through on the way to social content or in response to a search query from a news article. The first-party data that results from that behavioral context — purchase history, search behavior, category browsing, wish list additions, Prime Video viewing, and now Alexa interactions — is the most commercially predictive behavioral dataset in the advertising ecosystem. When Amazon shows an ad to someone who has searched for running shoes three times in the past month, added two pairs to their cart, and watches sports programming on Prime Video, it is not targeting based on inferred interest. It is targeting based on documented, authenticated, purchase-stage behavior.

The Empire Across Four Screens

What the $70 billion figure obscures, and what the 25 executives building Amazon’s advertising business understand most clearly, is that the company is not operating a single advertising platform. It is operating four distinct ones, each with its own audience, its own ad format, its own measurement infrastructure, and its own competitive position — and the commercial power of Amazon Advertising is the compounding effect of those four platforms sharing a single data layer.

The first is sponsored product advertising on the marketplace itself — the search-adjacent placements that appear when a consumer searches for a product category on Amazon.com or in the Amazon app. This remains the largest revenue contributor, and for most brands in physical product categories, it functions less like advertising and more like a digital shelf placement fee: not buying it means ceding ground to competitors at the exact moment a consumer is ready to purchase. Average cost-per-click sits around $1.18, and 70% of sellers on the platform advertise.

The second is Prime Video, which crossed 90 million U.S. subscribers and added advertising inventory when Amazon introduced a lower-cost tier with ads in early 2024. Thursday Night Football on Prime Video averages 15.3 million viewers — a number that makes it one of the most watched sports broadcasts in the country and gives Amazon a live sports advertising inventory that is competing directly with NFL broadcast rights holders for brand budgets that have historically belonged to traditional television. The streaming advertising opportunity is still in its early innings relative to the platform’s reach.

The third is display and programmatic advertising through the Amazon DSP, which allows advertisers to reach Amazon’s audience data outside of Amazon-owned properties — across third-party websites and apps, using Amazon’s purchase-intent signals to target users wherever they are browsing. This is the platform that competes most directly with The Trade Desk and the broader programmatic ecosystem, and it is the one growing fastest as Amazon’s authenticated audience data increasingly differentiates it from cookie-based alternatives.

The fourth is Stores and streaming audio — the branded storefronts within Amazon, Audible’s growing inventory, and Amazon Music’s ad-supported tier, all generating inventory that contributes to the compound total.

The AI Layer Being Built Over All of It

The 25 executives at the center of Amazon Advertising’s empire are, by every available account, primarily focused on a single question: how does AI accelerate the commercial performance of every layer of the platform simultaneously? The answers they are implementing span creative, targeting, measurement, and campaign management.

The Creative Agent, launched in 2025 and expanded across major global markets in early 2026 including Canada, France, Germany, India, Italy, Spain, and the UK, is an agentic AI tool that plans and executes end-to-end advertising creative workflows — generating imagery, copy, and format variations from a brand brief, without requiring design or production resources from the advertiser. For the small and medium-sized brands that represent a significant portion of Amazon’s seller base, this removes a meaningful barrier to advertising participation. For large brands, it dramatically accelerates creative testing velocity.

Rufus, Amazon’s AI shopping assistant, has added Sponsored Product and Brand prompt integration — meaning that brands can now reach consumers during the AI-assisted product discovery process, not just during conventional search and browsing. As AI assistants become a more significant portion of the discovery journey for Amazon shoppers, advertising presence within those assistants becomes a critical component of full-funnel visibility rather than an optional add-on. The brands that understand this early and invest in Rufus integration while competition for those placements is still developing will have a positioning advantage that becomes harder to replicate as the channel matures.

The measurement infrastructure sits over all of it, and it is where Amazon’s structural advantage is most durable. Unlike any other advertising platform at scale, Amazon can close the loop between an advertising exposure and a purchase with first-party certainty — not modeled, not probabilistic, but actual. A brand running campaigns across Prime Video, sponsored products, and the DSP can see which combination of exposures produced which purchases, at what intervals, among which customer cohorts. That closed-loop attribution is the commercial argument that every retail media network tries to make and that Amazon makes with more evidence than anyone else. It is also what the rest of the advertising industry is, in various ways, trying to replicate through first-party data investment, clean room technology, and the identity infrastructure deals — like Publicis and LiveRamp — that are reshaping the market’s structure in real time. Amazon already has it. Everyone else is catching up.
