If Valve's latest Steam Survey monthly figures are accurate, Steam on Linux enjoyed a very wild month of March. Steam on Linux is now above the 5% threshold and more than twice the size of the Steam on macOS marketshare.

Steam on Linux ended 2025 at around a 3.5% marketshare, dipped a bit in January, and fell to 2.23% in February. That's still much better than several years ago in the pre-Steam-Deck days when Steam on Linux was at around 1%. In absolute terms with the continued growth of the Steam user base, 2~3% was rather healthy considering all of its bumps over the past decade.

But Valve just published the Steam Survey results for March 2026 and they have never been so incredible for Linux... 5.33%! Steam on Linux was never above 5% and easily an all-time high for the Linux gaming marketshare, especially in absolute numbers. It was a massive 3.1% spike in March while macOS also jumped surprisinfly by 1.19% to 2.35%. The Steam Survey numbers show Windows losing 4.28%, down to 92.33%.

Part of the jump at least appears to be explained by Valve correcting again the Steam China numbers. Month over month they report a 31.85% drop to the Simplified Chinese language use and English use increasing by 16.82% to 39.09%. Other languages also showed gains amid the massive decline in Simplified Chinese use.

The latest numbers for March show around a quarter of the Linux gamers are running Steam OS.

Due in part to the Steam Deck APU being a custom AMD product and the popularity of AMD hardware on Linux for its open-source nature, AMD CPU use by Steam on Linux gamers remains just under 70%.
