If "this market" means supercomputers (as 'Cthulhu_ was talking about), then TPUs are certainly not perfectly positioned to capture this market, since they are only capable of doing bfloat16 arithmetic with high performance, and AFAIK incapable of fp64 at all. That means a HPL score of zero. TPUs will probably dominate AI training, but not so much supercomputing.
