I'm curious if there's anyone who studies these types of things who knows how common it is to have such overly ambitious plans for an IPO. I don't personally have enough context to know how much of an outlier this is. I'm also wondering if at this point any investors with the kind of money Elon is after really think that the the plan is rock solid so much as they are betting on Elon's ability to make a company worth a lot of money for investors.

“At nearly two trillion dollars, it’s instantly one of the biggest things in the market, which means every index fund has to hold it.”

This is nonsense. Plenty of index funds won’t be forced to hold it, including all of those tracking the S&P 500.
