Not yet, but there are several projects that exist to build it for Windows: https://wintty.io/ describes itself as "A native Windows terminal built on the Ghostty core" (i.e., wrapping libghostty in a Windows application), and is probably the one I'd start with. There's also https://noctty.com/ which has taken a similar approach.

Both are clearly LLM-assisted projects, but https://noctty.com/ has a very Claude-esque front page whereas https://wintty.io/ doesn't set off my LLM detectors nearly as badly. However, Wintty's download page says "Prebuilt builds are for sponsors. The source is free and always will be, and you can build it yourself" so if you decide you don't like that business model then you may wish to try Noctty, which does have prebuilt binaries.

NOTE: I have not spent any amount of time with either of those, so I can't give personal recommendations either for or against either.
