Valve published its Steam Year in Review for 2025, reporting that the platform delivered about 100 exabytes of data to customers in 2025, up from roughly 80 exabytes in 2024. The company said Steam users averaged 274 petabytes of installs and updates every day in 2025, roughly 11.42 petabytes per hour, or about 190,000 GB per minute, by Valve’s math.
Valve also reported that Steam reached a 42 million peak concurrent user count and has been growing at about 3.4 million concurrent users per year over the past five years. On the developer side, Valve said the revenue share paid out across all non‑Valve games on Steam in 2025 was 76%, reflecting the 75%/80% tiered splits it put in place in 2018. That figure does not include revenue developers may earn selling free Steam keys outside the platform.
This Year in Review arrived alongside other Valve updates this week, including a reassertion of a 2026 Steam Machine launch as part of the company’s broader product planning and communications; more on that is available in our coverage of Valve’s announcement reasserting a 2026 launch.
Those install and update totals highlight why storage, bandwidth, and distribution remain central to Steam’s operations and to developers’ release planning, they also help explain why Steam’s infrastructure and payout figures drew attention this week.
