The more interesting is HF turned down a $500M Nvidia investment late last year at a $7B valuation, after passing on a $235M round in 2023 at $4.5B — going from "we don't want a dominant investor" to a $13B full acquisition in under a year is quite the reversal.
Reversal would be "valued at 7B then valued at nothing", this is more like "nah, we want more" then "nah, we want more" then "yes, that's what we want :)".
