Elon Musk is currently the world's richest person, according to Forbes' live billionaire ranking. His documented assets center on Tesla and SpaceX, which now indirectly includes xAI and X, while property forms a much smaller part of his wealth. That fortune is an estimate, not a cash balance. Public share prices, private-company valuations, ownership structures, options, and debt can all affect the amount Musk could actually realize.

Tesla remains a major public asset
Tesla reported that musk beneficially owned 717.1 million shares, representing 20.3% of the company on December 31, 2025. The total includes shares held through his revocable trust and options he could exercise, according to Tesla's 2025 Form 10-K. "Beneficial ownership" is broader than shares sitting in a personal brokerage account.
It can include securities controlled through a trust and shares available through qualifying options. Tesla's market price therefore has a large influence on Musk's estimated net worth. Yet multiplying 717.1 million shares by the latest price would still be an oversimplification because the reported total includes options.
SpaceX provides wealth and control
SpaceX's June 2026 prospectus reported that Musk held 12.2% of its Class A shares and 93.3% of its Class B shares before the offering. That structure gave him 84.3% of the voting rights, with about 83.6% projected afterward, according to the SpaceX EU prospectus. Voting power measures control, not simply economic ownership.
Public investors may gain exposure to SpaceX's performance, but Musk retains the ability to determine major governance outcomes. SpaceX reported $18.674 billion in 2025 revenue and a $4.937 billion net loss. Its valuation—and Musk's stake in it—should not be treated like cash or a profitable, easily sold holding.
Where xAI and X fit
X and xAI are no longer best viewed as separate top-level pieces of Musk's fortune. Tesla's filing says they became subsidiaries of X.AI Holdings in March 2025, before SpaceX acquired that holding company in February 2026. Musk had said xAI's all-stock purchase of X valued xAI at $80 billion and X at $33 billion.
Both companies were private, however, so they did not have to publish the financial detail available from a public company. The practical result is a layered asset structure: This arrangement means xAI and X can contribute to the value of Musk's SpaceX interest. It does not justify adding their earlier announced valuations separately to his wealth.
- Musk owns a major, controlling stake in SpaceX.
- SpaceX owns X.AI Holdings.
- X.AI Holdings contains the xAI and X businesses.
Property is a comparatively small holding
Musk's real estate appears modest beside his corporate stakes. Fortune reported that he sold most of his California homes, described a SpaceX-rented Boca Chica residence as his primary home, and bought adjacent Austin properties for about $35 million. Even $35 million of real estate is tiny relative to multibillion-dollar company holdings.
Property may offer privacy, utility, or long-term value, but it is not the main driver of Musk's ranking. A rented residence is also not a personal asset. Readers should separate homes Musk owns from properties he occupies through a company arrangement.
How to read the net-worth figure
A billionaire ranking estimates the value of assets minus identifiable obligations. Public stock can be repriced continuously, while private-company interests require assumptions and periodic adjustments.
When interpreting Musk's reported fortune, check: The supplied public evidence does not provide a complete inventory of Musk's cash, funds, bonds, personal debt, or other investments. Any detailed claim about those categories would require additional verified disclosures.
- The date and source of the estimate.
- Whether options are included in share ownership.
- Whether voting control is being confused with economic ownership.
- Whether private-company valuations are being counted twice.
- Whether property is owned personally, held through another entity, or rented.
