Amazon Prime Video says its ad-supported streaming platform reach globally has hit 315 million monthly viewers.

That audience is based on Amazon’s internal data over the year to August 2025, and marks a sharp rise from a reach of 200 million monthly viewers recorded in April 2024. Jeremy Helfand, vp of Prime Video advertising, stated that reaching the 315 million monthly viewers mark represented a “transformative milestone” for the tech giant’s streaming platform.

“This expanded audience across 16 countries demonstrates our customer-obsessed approach to enhancing the viewing experience while delivering powerful opportunities for brands. We’re just beginning to unlock what’s possible when premium entertainment, engaged viewers, and innovative ad-tech converge with relevant and performant advertising at this unprecedented scale,” Helfand said.

Prime Video entered the advertising business in early 2024, flipping on ads for all of its U.S. users as a default option, with subscribers able to opt out of ads for a small monthly fee. Prime Video joined previously commercial-free services Netflix, Disney+ and Warner Bros. Discovery’s HBO Max in seeking out the revenue stream that advertising offered on top of subscription fees.  

On Nov. 5, Netflix revealed a new metric called monthly active viewers, or MAV, for its own ad-supported subscription tier, and claimed it has 190 million such viewers in the 12 countries where it offers an ad tier. Prime Video has launched advertising in 16 countries, including the U.S., Australia, Canada, France, Germany, India and the U.K.

The tech giant revealed in May the ad tier of Prime Video had reached over 130 million U.S. customers, up from a 115 million audience of monthly viewers recorded in 2024. That audience represents viewing for original and licensed series and films, live sports and events and free, ad-supported live channels on Prime Video.
