Overview

• Forbes’ Real-Time Billionaires tracker put Musk’s net worth at $500 billion on Wednesday afternoon after Tesla shares rose nearly 4%, adding about $9.3 billion in a day.
• Large portions of the estimate come from private holdings, including SpaceX at roughly a $400 billion valuation (Musk ~42%) and xAI Holdings at about $113 billion (Musk ~53%).
• Methodologies differ: Bloomberg’s Billionaires Index put Musk at $459 billion on the same day, underscoring how timing and valuation models change the totals.
• A Delaware judge voided Musk’s 2018 Tesla options award in January 2024; Forbes assigns only half its current value pending the outcome of his appeal.
• Tesla’s board has proposed a new compensation plan that could be worth up to $1 trillion if long-term targets are met, with initial vesting not beginning until 2033.
