No, seriously, I'm all for a multipolar world here, but he's right that the frontier is literally just those two companies at present.
Google is behind. MSL is doing better, but not by much. xAI is a dysfunctional joke. Thinking Machines aren't on the frontier. SSI's primary output is their announcement post. Poolside was bought by NVIDIA. Arcee aren't vying for frontier. Magic have been largely AWOL, aside from their recent blog post. Reflection have shipped nothing.
