" Elon Musk’s SpaceX Holdings Revealed. (Hint: It’s a Lot.)
 
Megarich CEO Elon Musk dominates the list of investing and corporate heavy hitters who own shares of SpaceX, with nearly half of the commercial space company’s outstanding stock under his control. For the first time, public funds have disclosed their SpaceX positions, and Musk sits alongside Nvidia, Alphabet, and others.

 
• Among corporate holders, Alphabet has a 551 million-share stake with a value of about $77 billion. That is down from its disclosed value of about $94 billion. But SpaceX stock has been falling, from $171 a share at the end of the second quarter to $140 on Friday.

 
• Meanwhile, Nvidia is also a major holder. It owns a 123 million-share stake, or just under 1% of the stock outstanding. That’s strategic as Nvidia sells a lot of GPUs to SpaceX, which merged with Musk’s AI company, xAI, in February.

 
• Fidelity, BlackRock, and Baillie Gifford are among the notable institutional shareholders with SpaceX stock. The Ontario Teachers’ Pension Plan is another large holder. Those four hold a combined 455 million-plus shares.

 
• Musk controls 6.4 billion shares, or 48.4% of the stock outstanding. That was valued at about $1 trillion at the end of the second quarter but is down to a mere $900 billion at the end of the week. Along with his Tesla stock, Musk’s net worth is about $1.1 trillion.

 
What’s Next: Musk’s trillionaire status sticks with SpaceX stock above roughly $120 (assuming stable Tesla stock). SpaceX stock weakened on concerns about selling when the IPO lockup ends. Another 319 million shares unlock this week. By year-end, some 4.2 billion shares will unlock. Musk can sell shares in June 2027.
