Amazon has firmly announced its arrival as a dominant force in global advertising. With 315 million people now watching Prime Video’s ad-supported tier every month, the company has positioned itself not only as an entertainment platform but as one of the world’s most powerful digital advertising ecosystems.

Netflix, which revealed last week that it has more than 190 million monthly ad-supported viewers, now faces direct competition from Amazon for scale. This gap of over 100 million viewers signals a major shift in the hierarchy of streaming giants. Consequently, the battle has moved beyond content libraries to a contest driven by advertising reach, targeting precision, and global viewer engagement.

Prime Video’s 315 million monthly viewers stand out not only because of the sheer number but also because of their consistent engagement across licensed films, original series, live sports, and FAST channels. Therefore, for advertisers, Amazon now provides a high-reach entry point into diverse audience behaviors. This happens in a media environment where attention is costly and fragmented. Beneath the headline is a deeper truth: the streaming economy is changing rapidly under competitive pressure.

A Battle of Scale Between Amazon, Netflix, and the Rest

For years, Netflix remained the most attractive streaming ad platform. Its cultural relevance, binge-driven habits, and global footprint made it the top choice for brands. However, Amazon has quietly constructed an advantage that Netflix cannot quickly match. Prime Video sits inside a much broader system. Crucially, it benefits from millions of existing Prime subscribers, a strong household presence built through shopping and logistics, and vast first-party retail data. Furthermore, it utilizes multiple advertising surfaces that include Fire TV, Twitch, and Amazon’s own DSP.

This ecosystem allows Amazon to deliver highly targeted ad experiences that go beyond Netflix’s current capabilities. Buying Prime Video inventory gives advertisers access to a retail engine rich in behavioral data, not just a streaming audience. Netflix still holds immense cultural influence, yet it operates with fewer cross-device touchpoints and limited direct consumer data compared to Amazon. As Prime Video’s ad-tier audience surges, Netflix faces new pressure in areas that matter most to advertisers. Viewers who convert are now more important than viewers who simply watch. Ultimately, Amazon signals that it can deliver both.

Entertainment No Longer Dominates, Advertisers Want Precision

Amazon’s advertising business has long operated as a quiet giant. Today, it generates tens of billions in annual revenue. Prime Video’s expansion into ad-supported content strengthens that position by pairing premium storytelling with measurable performance. As a result, Amazon no longer offers only ad spaces. It offers a loop that connects entertainment to commerce in one ecosystem, allowing viewers to watch, shop, and convert within the same journey.

The wider industry now moves rapidly toward ad-supported tiers, sharper targeting models, and bundled platforms. Netflix, Disney Plus, and Warner Bros. Discovery all recognize this movement. Nevertheless, none can combine retail and streaming the way Amazon can on a global scale. This structural advantage will shape the competitive landscape from 2026 onwards.

Streaming Becomes the New Television

Streaming has evolved from a complement to traditional TV into the dominant form of modern television. Prime Video and Netflix together now reach more than 500 million ad-supported viewers every month. This new version of television is data-driven, personalized, and interactive. Specifically, it integrates viewing behavior into wider digital ecosystems in a way traditional broadcast could never achieve.

For advertisers, the shift is decisive. Budgets will move even more aggressively into streaming environments. Therefore, measurement models must evolve to track cross-platform behavior. The future of digital advertising will merge retail media with streaming media. Amazon understands this, and Netflix does too. The rest of the industry is running to catch up.

The Takeaway

Prime Video’s 315 million monthly ad-tier viewers mark more than a milestone; they signal a global power shift. Entertainment now fuels commerce, and commerce fuels advertising. For Amazon, the milestone reinforces a hybrid model that blends storytelling with retail. Conversely, for Netflix, it introduces the most serious competitive pressure in years. For advertisers, it opens a new frontier of global reach that is high quality, measurable, and directly linked to purchase behaviors.

For the broader streaming industry, this is the beginning of a new era. Competition for advertising dominance, targeting accuracy, and the most effective routes to monetizing attention define this new era.
