Elon Musk Becomes the World’s First Trillionaire
Elon Musk, the CEO of Tesla and SpaceX, has reached a historic financial milestone, surpassing $600 billion in net worth thanks to SpaceX’s soaring valuation. This ascent positions him as the first individual to attain trillionaire status globally.
In early December 2025, SpaceX reportedly submitted a tender offer that valued the company at about $800 billion, up from roughly $400 billion in August. Two SpaceX investors shared this information with Forbes. With Musk owning an estimated 42% stake, his personal fortune would surge by about $168 billion to roughly $677 billion as of December 15, 2025.
The tender offer coincides with SpaceX’s plans for an initial public offering (IPO) in 2026, which some investors believe could value the company at around $1.5 trillion. Forbes confirmed that multiple sources within SpaceX had previously discussed the IPO and its potential scale.
Requests for comment from Musk’s team and SpaceX representatives did not receive a reply from Forbes.
Even without an IPO at the $1.5 trillion valuation, Musk’s estimated $336 billion stake in SpaceX remains his most valuable asset. His 12% holding in Tesla is currently valued at about $197 billion, not accounting for stock options tied to a 2018 CEO Performance Award, which a Delaware judge voided in January 2024.
If the appeal regarding that stock option award goes against Musk, Tesla could still provide an alternative path toward achieving trillionaire status.
Surpassing the $600 billion mark is the latest landmark in a string of notable financial milestones Musk has reached over roughly the last five years.
