Other than the ~12% I just estimated, lots of large-but-not-famous places will be buying ~1k, and small places will be buying tens to hundreds, and quite a lot of AI bubble money will be invested in startups that claim they only need one.
Probably some scientific modelling that can be done on these, so I bet some universities and private labs will be buying them. NASA, SpaceX, RocketLab, Helion, etc.
There's also probably a lot of AAA game studios and art studios for movies etc. who are each buying dozens of these graphics processing units for… graphics :P
