Netflix's $3 Billion Ad Business Runs On Amazon's Infrastructure. That's Not A Coincidence.

Netflix's advertising revenue is projected to double to $3 billion in 2026. Its ad-supported tier accounts for 60% of new sign-ups in ad markets, per its Q1 letter to shareholders. Programmatic buying has reached nearly 50% of its non-live inventory. The ad business is scaling. What has not been reported is the degree to which that scaling depends on the same company now selling the targeting data.

Amazon is Netflix's cloud infrastructure provider. Every stream delivered to 300 million subscribers across 190 countries runs on Amazon Web Services (AWS), which handles Netflix's compute, storage, database architecture, and content delivery backbone. Netflix's annual AWS spend is estimated above $1 billion. State of Streaming previously covered the Amazon Audiences integration in prior coverage. The targeting deal is the newest layer of a vendor relationship that has been load-bearing for almost two decades.

The Advertising Deal in Full

Starting Q2 2026 in the United States, advertisers can layer Amazon Audiences onto their Netflix campaigns — segments built from what Netflix describes as trillions of Amazon's proprietary shopping, streaming, and browsing signals, per the Netflix announcement. The integration covers 11 countries at launch, with expansion to all Netflix ad-supported markets planned through year-end.

Netflix's programmatic partners now include Google DV360, The Trade Desk, Yahoo DSP, and AJA alongside Amazon, per Q1 reporting. The breadth is intentional. Netflix is moving from a premium managed-service buy to a standard planning line item. Amazon's Complete TV toolset positions Netflix as a managed allocation inside Amazon's planning layer, not just its buying layer. The planner and the infrastructure provider are the same company.

What the $3 Billion Number Actually Means

Netflix captures less than 5% of a U.S. streaming ad dollars projected to be around $40 billion this year. Its advertiser base grew 70% year over year to 4,000 advertisers. The Amazon targeting integration was timed for upfront season because it gives buyers the missing performance piece to match the existing brand-safety argument, and a serious reason to consider shifting budget from search, social, and retail media into premium streaming environments.

In early testing with Tinuiti, campaigns running against Netflix inventory with enhanced targeting exceeded benchmarks by more than 75% across financial services, education technology, and retail, per Marketing Dive.

The Structural Question Media Buyers Should Be Asking

Amazon's authenticated identity graph covers 88 million of the 101.6 million U.S. households with a broadband connection according to our Q1 2026 Unified Streaming Power Index.

Amazon benefits from Netflix's advertising growth on two ledgers: DSP revenue when its data powers Netflix campaigns, and AWS contract revenue when Netflix's subscriber base expands. No other DSP partner in Netflix's programmatic stack holds both positions. Disney, Roku, and other supply partners in Amazon's 2025 partnership wave contribute inventory. None carry the infrastructure contract underneath the content.

For executives allocating media budgets, the practical implication is direct: Netflix's premium CTV inventory is now reachable inside the same workflow as Amazon's retail media stack — same identity graph, same measurement tools, same planning interface. The CPM premium remains. The friction is gone.

Ecosystem builders compound. Netflix and Amazon have been doing it at the infrastructure layer since 2009. The advertising layer is new. The return on that relationship is not.
