In December 2025, Linux users constituted 3.58% of the Steam userbase, marking a growth from 2.68% in September. This increase can largely be attributed to the end-of-life of Windows 10, which prompted many gamers to transition to Linux, resulting in nearly a 1% rise over three months.
Despite a slight drop in the market share of SteamOS, which lost almost 2% during the same period, the overall acceptance of Linux as a gaming platform continues to rise. Fedora-based distributions like Bazzite have seen significant growth in popularity, while Ubuntu and other categories also recorded minor losses.
Valve's updated data reveals that Linux adoption had been misrepresented in previous reports, as initial figures suggested a plateau. New insights indicate that the trend is, in fact, upward, reflecting a shift in the gaming landscape where Linux is gaining traction among desktop users.
