SpaceX priced its IPO at $135 per share Thursday, implying a $1.8 trillion market cap for the company. That boosted Musk’s net worth by $188 billion to an estimated $982 billion, according to Forbes’ calculations. Then on Friday, the rocketmaker’s stock started trading at $150 per share and closed the day at $160.95 per share, implying a valuation of $2.2 trillion for the company. That easily made Elon Musk the world’s first trillionaire, worth an estimated $1.1 trillion. He was briefly worth a record $1.2 trillion, when SpaceX’s stock peaked at $176.52 per share Friday.
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 Thursday, Forbes had been valuing Musk’s estimated 40% stake (before dilution from the public 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 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.
