Steam survey for December 2025 shows Linux holding to 3.19%

Valve have released the Steam Hardware & Software Survey for December 2025, bringing with it a fresh look at how Linux / SteamOS are doing on Steam. For this month we see that Linux is pretty much just holding steady, after hitting an all-time high for November 2025.

The overall numbers of user share across platforms on Steam:

• Windows 94.95%
• Linux 3.19%
• macOS 1.86%

Currently this puts the Linux user share on Steam at its second highest.

And as usual here's a snapshot look at the trend over time from our dedicated Steam Tracker statistics page:

Last month I did a small tweak to that page, to improve how we handle the event markers. Since you can select different dates, sometimes they went off the chart - now their positioning is a lot smarter. And, as per requests, it shows when Windows 10 hit end of life too. Hopefully you continue to find it useful for a historical look.
