Elon Musk just became the first trillionaire in world history. SpaceX’s stock began trading on the Nasdaq Friday at $150 per share, implying a nearly $2 trillion market cap for the company.
Forbes estimates that Musk is now worth $1.1 trillion as of just before noon eastern 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.
Musk, who serves as chairman, CEO and chief technical officer of SpaceX, owns 4.8 billion shares of the rocketmaker, worth $715 billion. He has another 350 million stock options with an exercise price of $8.40 per share, worth $50 billion, giving him a 38% stake in the company, worth $765 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 $163 billion, plus options to acquire another nearly 8% stake, worth $113 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.
Not included in Forbes’ estimate of Musk’s net worth: performance-based restricted shares that could boost his stakes in SpaceX and Tesla to 47% and 29%, respectively (before taxes and the cost of unlocking the restricted shares). To earn all that stock, Musk will have to achieve lofty goals like growing SpaceX and Tesla’s market caps to $7.5 trillion and $8.5 trillion, respectively, and establishing a permanent human colony on Mars with at least one million inhabitants.
