After some rumors, Google confirmed in July 2025 that ChromeOS will "merge" with Android under one unified platform. It was formally announced at the Snapdragon Summit in September 2025. Internally, it is known as codename Aluminium.
The existing Linux-based ChromeOS will be replaced by a desktop-optimized Android-based operating system. The same Android software would run on desktop and mobile and be adapted for the different display sizes. Like ChromeOS, the desktop version of Aluminium will work on both ARM and x86 processors. The latter port is expected to be the first mainline maintained x86 architecture version of Android.
The new OS was announced on May 12, 2026, during Google I/O. It will be used by Googlebooks, a line of premium laptops by third-party OEMs, and many Chromebooks will also be able to use the new operating system. The company clarified that Aluminium was a codename during development and would not be the actual name, and that an actual name will be unveiled later in the year.
