"While the April 2026 data shows a monthly decline, other reporting highlights a broader upward trend for Linux on Steam."

A Measured Decline in April 2026

According to Valve’s Steam Hardware & Software Survey for April 2026, Linux usage accounted for 4.52% of total Steam users across Windows, Mac, and Linux platforms. This represents a month-over-month decrease of 0.81% compared to the survey results for March 2026.

Specific details from the April 2026 survey include:

  • Operating System Breakdown: Among Linux users on Steam, the share attributed to SteamOS declined by 1.43%.
  • New Entries: The survey recognized distributions CachyOS and Bazzite for the first time.
  • Historical Context (April data):
    • April 2024: 1.90%
    • April 2025: 2.27%
    • April 2026: 4.52%

Long-Term Growth and Driving Factors

While the April 2026 data shows a single monthly dip, the long-term trend remains upward. By a later date, Linux had exceeded 5% of the Steam market share. This is a significant increase from 2.57% in June 2025 and 3.05% in October 2025.

The primary factor cited for this growth is the Steam Deck, a handheld gaming device manufactured by Valve. The Steam Deck runs on SteamOS (a Linux-based operating system), and its users are counted as Linux users in Valve’s survey. The survey's methodology has been noted as potentially having a small sample size relative to the total number of Steam users.

"A platform share of 5% is noted as a size that can influence game developers to consider optimization efforts for the operating system."

Contributors and Challenges
  • Proton: Valve has developed Proton, a compatibility layer that allows Windows games to run on Linux. This technology has led to thousands of titles being rated as "Steam Deck Verified" or "Playable."
  • Sales and Hardware: Sales of the Steam Deck are a key driver of Linux adoption. One source notes that the Steam Deck was reported to be out of stock globally, which may be a factor in the April 2026 monthly decline.
  • Anti-Cheat Compatibility: A persistent challenge for the platform includes compatibility with anti-cheat software used in competitive multiplayer titles.
  • Future Outlook: The end of support for Windows 10 is cited as a potential factor that could encourage users to explore alternative operating systems.
