As far as I understand, the companies in the list (didn't check if OP's company is included) are buying from Grayscale. Grayscale has been buying up BTC and ETH for years, but ramped it up recently (I want to say Q1/Q2, but don't quote me on that).

So these orders are not hitting "the public market", it's coming from Grayscale inventory (not even that, since the companies aren't buying directly and taking custody).

Also, good point on BTC supply being less than the 21 mil cap / whatever was mined already.
