The world's richest man has a new fancy title.
Elon Musk is now the world's first trillionaire after SpaceX's public debut.
SpaceX began trading at $150 per share — $9 above the roughly $141-per-share threshold that would push Musk's net worth over the trillion-dollar mark.
SpaceX's stock recently surged 28% to around $173, solidifying Musk's status as a trillionaire.
At SpaceX's IPO price of $135 per share, Musk's stake in the company was worth $688 billion. That brought his total net worth to $971 billion going into Friday's trading, according to Bloomberg.
Shares in Musk's other companies — electric carmaker Tesla, brain-chip company Neuralink, and tunneling business The Boring Company — made up the bulk of the rest of his net worth.
All things equal, Musk's SpaceX stake had to reach $717 billion for him to become the first-ever trillionaire. To get to that point, SpaceX needed to hit a share price of $140.71.
At the time of SpaceX's market debut, Musk owned about 39% of SpaceX's outstanding shares. He has the potential to unlock another 10% that vests if certain performance conditions are met.
Musk was already the world's wealthiest person, but the IPO puts him even further ahead of the pack. Google cofounder Larry Page is a distant second, with a net worth of $304 billion, according to Bloomberg.
Musk's net worth has more than doubled over the past year. The jump largely reflects SpaceX's growing valuation. The company's value doubled from July 2025 to December 2025 after it was valued at $800 million in a secondary sale. That's before it merged with xAI, Musk's AI company, in February 2026.
Within minutes of going public, SpaceX was valued at more than $2 trillion.
Tesla's stock has also grown, though not at such a dramatic rate. The electric carmaker's share price is up 22% over the past year, and Musk's stake is now worth $165 billion.
So where does Musk go from here? There's only one answer: Mars.
