Everyone knows Elon Musk is the genius behind the biggest stock market debut of all time. But even a genius, in the immortal words of Jim Collins, needs a thousand helpers. So who, exactly, is helping him run SpaceX?
The company Musk founded in an El Segundo, Calif. warehouse in 2002 is not quite the company it was even 18 months ago. In February 2026, Musk folded his artificial intelligence startup xAI into SpaceX in an all-stock deal. The deal created a $1.25 trillion private behemoth—part rocket company, part satellite constellation, part AI firm—before handing shares of it to the public. As of the close of trading on June 18, SpaceX’s market cap was hovering around a towering $2.44 trillion.
