And so it begins. SpaceX has launched its initial public offering (IPO) on the Nasdaq. More than $75bn has been raised for the offering, boosting the company past a $2.1-trillion valuation. With his 42% holding now worth about $900bn according to the Financial Times, and his Tesla holding at $280bn, founder Elon Musk becomes the first human trillionaire. Yes, those numbers are unfathomable, and it’s only going to get more incomprehensible.
