For a moment step into the theory of mind of the AI believer. That’s the common mindset in finance today. You believe that AI is displacing white collar work, and soon with robots it will displace physical work. Your personal job is to help set the rules for stocks to be included in the index. You believe that the point of indices is for passive investors to automatically be invested in the diversified set of top public companies (weighted by market cap). During previous economic shifts, where companies went public early and were already in the index during their growth phase, passive investors broadly benefited from that growth. These new AI companies have stayed private much longer, meaning that the index has missed the opportunity to “buy low” and build up a stake so far.

You believe that the owners of the leading AI companies stand to become owners of most wealth. Furthermore, that we are at an inflection point where the value of these companies rises so rapidly that delays in index investment will set in stone a permanent inequality, where early tech VC and other private funds own a huge portion of the economy. The few-$T downside risk of AI bubble popping this year feels to you like a minor concern compared to index funds being shut out of this wealth due to some arbitrary rules, which have been changed before and can be changed again. Delaying investment in these huge public companies feels like a more dangerous decision than buying in when they become public.

In short, there are two possible stories here:

1) Wall Street is AGI-pilled and thinks AI companies will be worth many trillions of dollars

2) Wall Street expects the AI bubble to pop and is trying to make the public into bag holders by selling a few hundreds of billions of dollars in the IPO

I think the second story actually doesn’t hold together, because Wall Street is making a bunch of correlated bets. The IPO cash is just one more source of capital, and much of it going to be used to make investments which are also correlated bets.
