ChromeOS jumped down several points in the same time period. So maybe some update of ChromeOS got misconfigured?
It's schools letting out for summer. Most Chrome OS users are schoolchildren using their school issued Chromebooks. We will see it jump back up from ~1.5% to ~5% when school starts in September. The same pattern happened to Chrome OS usage in summer 2025.
I guess my point is that it is nearly impossible to get reliable counts from user agent statistics, etc. (lots of crawlers, that identify as a regular desktop as well etc.). The best way would probably to do real-world surveys among random population samples. But that costs money/time.
It's about the same as Firefox share, which is getting smaller.
