Steam users downloaded 100 million terabytes of games and updates in 2025

Valve recently released its Steam Year in Review for 2025, where the company highlighted several improvements introduced for developers and publishers, while also sharing an update on its upcoming hardware. Alongside those updates, Valve also shared some interesting details about how much data users downloaded through Steam last year.

According to Valve, the platform has been growing at a steady pace. Around five years ago, Steam crossed 25 million concurrent users for the first time. And right now, that number is above 42 million. With more players joining the platform each year, the amount of data being downloaded has also grown significantly.

In 2024, Steam delivered around 80 exabytes of game downloads and updates to players. That number increased to 100 exabytes in 2025. To put that into perspective, 100 exabytes equals roughly 100 million terabytes of data, which is an enormous amount of game downloads across the platform.

Valve also shared a breakdown to help illustrate how massive that number really is. On average, Steam users downloaded about 274 petabytes of game installs and updates every day throughout the year. That translates to roughly 11.42 petabytes per hour, or about 190,000 GB of data every minute being downloaded from Steam servers.

Valve also noted that since it introduced the 75% and 80% revenue share tiers in 2018, more developers have reached those higher revenue levels. In 2025, the average revenue share paid out to developers across all non-Valve games reached 76%.
