No, this was not allowed. Until a certain someone with deep connections to the corrupt government (coughspacexcough) changed the rules for themselves for the upcoming IPO. It's going to be.... ballistic.

What do you mean? If a US company is big enough it ends up on the S&P500 _eventually_. I know index funds don't auto-include IPOs immediately, but eventually they are forced to buy into them.
