Investors might ignore AI giants like SpaceX, but their 401(k) pension accounts won’t

While Americans might want to ignore all the hubbub around SpaceX, Elon Musk and initial public offerings (IPOs), their 401(k) pension accounts likely can't.

SpaceX is now worth US$2.1 trillion after its stock launched 19.2 per cent higher in its debut on Wall Street. Whether or not you believe it deserves to be worth more than Exxon Mobil, Bank of America and Coca-Cola combined, the collective market does. And if SpaceX maintains that big a value, it will join some high-profile stock indexes.
