## Summary
Valve published October 2026 Steam Survey results showing Linux at 3.95% market share, a 0.05% increase from the revised September figure of 3.9%. The original September data had shown a dramatic drop to 3.05%, but Valve later adjusted this upward, attributing the initial anomaly to a surge in Simplified Chinese users that typically inflates Windows numbers relative to Linux. Year-over-year, Linux has grown from the 3% milestone first reached in October 2025.

Among Linux distributions, CachyOS—an Arch Linux derivative—now leads at 16.3%, edging ahead of Valve's own SteamOS at 13.89%. AMD CPUs continue to dominate Linux gaming hardware at just under 70% penetration, a figure heavily influenced by the custom AMD SoCs powering both the Steam Deck handheld and Steam Machine console. Windows remains dominant at 93.7% overall, with macOS trailing at 2.35%.

## Survey methodology and distribution breakdown
- **Revised methodology:** Valve adjusted September 2026's initially reported 3.05% Linux share upward to 3.9%, indicating the Steam Survey's susceptibility to demographic shifts in regional user bases.
- **Distribution hierarchy:** CachyOS, an Arch Linux-based distribution optimized for performance, has overtaken SteamOS as the most popular Linux gaming platform at 16.3% versus 13.89%.
- **Hardware platform dominance:** AMD CPU share among Linux gamers holds just below 70%, reflecting the continued market presence of Steam Deck (AMD Van Gogh APU) and Steam Machine (AMD custom SoC) hardware.
- **Regional volatility:** Simplified Chinese user fluctuations continue to introduce month-to-month noise in relative platform share, disproportionately affecting Linux versus Windows comparisons.
- **Annual trajectory:** Linux gaming share has grown approximately 0.95 percentage points year-over-year from the 3.0% threshold crossed in October 2025.

## Why it matters
The CachyOS surpassing SteamOS signals maturation beyond Valve-curated platforms, suggesting Linux gamers increasingly favor rolling-release, performance-tuned distributions over console-like experiences. For distribution maintainers and hardware vendors, the AMD SoC dominance in survey data reinforces where optimization efforts yield the greatest user impact, while the persistent Windows supermajority underscores that Proton compatibility layers remain critical infrastructure for Linux gaming viability.
