I just learned there are a whole bunch of bitcoin ASIC manufacturers. I thought it was a thin market but:
Bitmain
MicroBT (Whatsminer)
Canaan (Avalon)
BitFury
Chain Reaction
BitDeer
Inosilicon
Auradine
Zetagig
soon: Block
...and at least 2 more in stealth mode

Bitmain probably has >90% market share.
