PayPalValve 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.
As for December 2025 the most popular Linux distributions were:
- SteamOS Holo 64 bit 20.41% -6.01%
- Arch Linux 64 bit 12.24% +2.27%
- CachyOS 64 bit 8.45% +1.71%
- Linux Mint 22.2 64 bit 8.43% +1.07%
- Bazzite 64 bit 6.60% +1.07%
- Freedesktop SDK 25.08 (Flatpak runtime) 64 bit 5.72% -0.24%
- Ubuntu 24.04.3 LTS 64 bit 4.12% +0.26%
- EndeavourOS Linux 64 bit 2.92% +0.82%
- Pop!_OS 22.04 LTS 64 bit 2.25% +0.35%
- Fedora Linux 43 (KDE Plasma Desktop Edition) 64 bit 2.20% +2.20%
- Ubuntu Core 22 64 bit 2.17% -2.12%
- Manjaro Linux 64 bit 2.15% +0.25%
- Other 23.88% +3.45%

10% by 2030 or so seems inevitable now. I think at that level, it's the point where people can largely stop caring.
I mean, if you just want to see Microsoft lose OK that won't be done.
But at 10%, you'll be able to buy a mouse or a monitor or whatever, and assume its firmware is on LVFS. Any game publisher not bothering to at least test with Proton, will be truly an outlier.
From the consumer's point of view, pragmatically, it'll be about the same as 50%.
Quoting: KimyrielleI like that trend line. :DAnd it's better than that, really. It looks an awful lot like two trend lines, one of very gradual increase up to the Steam Deck release, and then a significantly steeper rise from Steam Deck release to now.
