IPOs aren't what they once were. The burden of being a public company has increased (SOX and related public company costs are $5-10M/year), so companies are far more likely to stay private. That has created a positive feedback cycle as the private funding ecosystem has become increasingly robust, which is why you see so many $100B+ private companies.

Also keep in mind that the biggest companies during that bubble had peak market caps of ~500B and then lost ~90%, so 400-500B in losses each and total internet related losses of a couple trillion. If NVDA lost 90%, it would be down 4 trillion dollars, or twice that total just by itself.

AI company valuations collapsing would have meaningful impacts on the broader market. Big pension/mutual funds are important sources of capital across every sector, and if they're taking big losses on NVDA, GOOG, and a portfolio of privates, it will have a chilling effect on their other activity.

The costs are a weak argument. The more stronger argument for why they arent going public any time soon is that OAI in particular is a corporate governance nightmare, in which the way they transmit information about their firm and financials will have to completely change.

Theres also plenty of money washing around in private markets so no need to go public. Staying private is an advantage.
