Note that these numbers include illiquid (pre-exit) valuations.
2021 and early 2022 was a huge bull market — many private companies raised money in insane valuations that aren’t realistic today. Suppose they didn’t raise money again or go public in mid/late 2022. In that case, it’s likely that their valuations were last updated around the bull market’s peak, in which case they’re almost certainly systematically inflated.
