Elon Musk became the world’s first trillionaire with today’s SpaceX IPO, the largest ever. Retail investors, who were allocated about 20% of the deal, along with Musk’s confidants and colleagues, got a lot richer, too.

The company sold $75 billion worth of shares at $135 a piece, valuing it at $1.77 trillion by Friday morning. SpaceX’s market cap stands at over $2 trillion after its first day of trading.

Investor demand was massive as shares opened on the Nasdaq at $150 and closed at $161 a share. The boost is a positive sign for Anthropic and OpenAI, which are expected to go public in mega offerings later this year.
