That’s about 26% more than SpaceX’s stated private market valuation ($1.25 trillion). CNBC.
Elon Musk owns about a 43% stake in SpaceX, while Tesla only has a 13% stake. This now means SpaceX represents more than half of Musk’s paper wealth, according to the report. CNBC.

The space company is a leading provider of orbital launch services and has multibillion-dollar agreements and contracts with NASA and the U.S. Department of Defense. Additionally, the SpaceX IPO, scheduled to begin this year, will reportedly value the company even more and increase Musk’s wealth. CNBC reported.
