This isn't just an Anthropic issue, but more and more of the upside of companies have been captured in private markets prior to IPO for around the last decade. This is a consequence of so much money floating around, that IPOing is now the last stop on the train instead of one of the early/middle stops where a company actually needs to raise money.
