Elon Musk just became the first trillionaire in world history. SpaceX’s stock began trading on the Nasdaq Friday at $150 per share and closed at $160.95 per share, implying a nearly $2.2 trillion market cap for the company. Forbes estimates that Musk is now worth $1.1 trillion as of the close of trading Friday, up from $982 billion on Thursday, when SpaceX priced its IPO at $135 share. The IPO pricing boosted Musk’s fortune by $188 billion yesterday, according to Forbes’ calculations. SpaceX’s stock peaked at $176.52 per share Friday, briefly making Musk worth a record $1.2 trillion.

Musk, who serves as chairman, CEO and chief technical officer of SpaceX, owns 4.8 billion shares of the rocketmaker, worth $767 billion at Friday’s close. He has another 350 million stock options with an exercise price of $8.40 per share, worth $53 billion, giving him a 38% stake in the company, worth $821 billion. Before SpaceX priced its IPO on Thursday, Forbes had been valuing Musk’s estimated 40% stake (before dilution from the offering) at around $500 billion, based on the $1.25 trillion valuation of SpaceX’s merger with Musk’s artificial intelligence and social media company xAI in February. (xAI previously merged with X–formerly Twitter–in March 2025.)

Musk also owns just over 10% of $1.5 trillion (market cap) Tesla, worth $168 billion, plus options to acquire another nearly 8% stake, worth $116 billion. Rounding out his net worth are smaller stakes in his brain interface startup Neuralink and his tunneling firm Boring Company, plus several billion dollars of wealth from previous Tesla share sales.
