Linux Kernel, Firefox, Dropbox, Discord, Cloudflare, Windows, AWS.

Idk, looking pretty good to me, unless you think none of these count.

Considering everyone seems to hate C++ nowadays, and Rust looks like the only existing alternative. Hard to imagine the trend won't continue.

it's getting built into some pretty widepread applications: firefox is a big one, it also runs a lot of the super-low-level parts of dropbox. I'd say it's overtaken haskell for adoption at least.
