Despite much noise being made about the Windows 10 end of life and the suggestion that people should move to Linux, based on the Steam on Linux market share, it seems switches have been quite moderate at best. For December 2025, Linux now accounts for 3.19% of market share with a month-over-month marginal dip of 0.01% from the all-time high of 3.2% in November.
While muted in December compared to November, the year-over-year growth for Steam on Linux has been better. In December 2024, market share was at 2.29% and in December 2023, it was at sub-2% levels.
AMD CPUs were the most common among gamers, with usage reaching an all-time high of 71.93%, that"s up 5.2% compared to the month before. Notably, there are significantly more AMD CPUs among Steam on Linux gamers compared to those on Windows (47.27%).
Furthermore, the Steam Deck’s custom GPU accounted for 21.4% of the Linux GPU market, indicating that about one-fifth of Linux gamers are using the handheld device which is powered by the Arch Linux-based SteamOS. The adoption of SteamOS is one of the main drivers on Steam on Linux growth, and the continued maturation of Steam Play (Proton), which lets you play non-Linux games on Linux is also helping a lot.
Going into the future, further growth is expected for Steam on Linux thanks to upcoming hardware such as the Steam Frame and new Steam Machine iterations. Another interesting thing to note about the dip we saw in December is that absolute number of Steam on Linux users.
