Steam Spike Signals Linux Desktop Surge

Valve's March 2026 Steam Survey shows Linux usage on Steam leapt to 5.33%, driven in part by SteamOS/Deck adoption and by Valve's correction of China-sourced statistics. The data also shows about a quarter of Linux gamers run SteamOS and that AMD hardware dominates Linux Steam users (~70%). — A persistent, measured uptick in Linux desktop share inside the largest PC gaming marketplace can change developer priorities, hardware vendor strategies, and regulatory attention toward platform gatekeeping and preinstalled OS ecosystems.
