Initially Valve’s Steam Hardware & Software Survey for December 2025 showed Linux at 3.19%, but they appear to have amended it with a nice boost for Linux. There were a few issues I spotted like languages and such not adding up, but now they do so it appears there’s a few corrections that were made to it this month.
Now the latest figures from Valve show for December 2025:
Windows: 94.23%
Linux: 3.58%
macOS: 2.18%
The heck happened in March?
Survey error. They oversampled the Chinese market. In fact, you can also see a huge increase in Chinese language whenever there’s a huge drop un Linux marketshare. It hashappened 2 times that I can remember.

could’ve been a flawed survey like this one but Valve never fixed it?
I mean there’s isn’t anything to fix. Could just be an unlucky month in selecting people for the survey. As the other person said, it does seem to be a statistical anomaly or actual error. But that is still a pretty massive dip for either of those two options. In and of itself also kinda statistically unlikely, hence my question.
The December survey was bugged, March could’ve been similar but never fixed. Before this fix, December had numbers that were adding up to more than 100% so it was a bug not just bad luck, they didn’t even redo the survey they just reprocessed the same data.
