A company can have poor fundamentals compared to its stock price, and also have an enormous P/E multiple if it has committed investors. We've seen this with multiple meme stocks and Tesla. I have no doubt SpaceX will fly high for a while and people will make a lot of money, but I don't think the company is going to make $320bn/year in AI services (with 74% profit) by 2030 as the S-1 suggests. At some point the market price will coincide with real earnings.
