With Tesla as the reference class, long enough to render shorters insolvent.

Not long unless they bend the rules. The voting control, the restrictions on shareholder lawsuits, the fast track rules for NASDAQ, the shell game of different companies, etc is all meant to prop up a price that doesn’t make sense. Otherwise they would behave like everyone else and do a normal IPO. They can’t do that because it won’t keep its price.

Goldman Sachs projects SpaceX’s total revenue to reach $474 billion in 2030, up from $18.7 billion last year. That’s 25x in just 4 years. It shouldn’t take long to check if real growth is along this predicted trajectory. But by that time Elon Musk will have sold enough of his shares. We will pay through index funds in our 401(k).
