Deepmind is owned by Google, but it's British and they've been behind a lot of significant conceptual results in the last couple years. Most significant progress is just "engineering", so it's all done by US corporations.

Other than that there's also things like roformer, but I'm going to assume you won't count that as significant. US universities then certainly don't produce anything significant either though.
