Elon Musk has attained a historic personal wealth milestone following the merger of his aerospace company SpaceX and his artificial intelligence firm xAI, positioning him as the world’s wealthiest individual according to modern records.
Forbes estimates Musk’s net worth at $852 billion, a figure bolstered by an $84 billion increase after the merger valued the combined entity at $1.25 trillion. Prior to the deal, Musk held a major stake in SpaceX and a controlling interest in xAI. The consolidation now places the bulk of his fortune within this newly formed, trillion-dollar corporation, surpassing the peak wealth of previous record-holders such as John D. Rockefeller, Jeff Bezos, and Bill Gates.
SpaceX now constitutes Musk’s most valuable asset. His portfolio also includes a significant stake in Tesla, along with stock options from a landmark 2018 compensation package. That pay plan, approved by shareholders in November, could eventually yield up to $1 trillion in additional value contingent on Tesla achieving specific long-term market capitalization targets.
This merger represents a second major consolidation for Musk in under a year. In March, he brought together xAI and the social media platform X (formerly Twitter), a deal that valued xAI at $80 billion and X at $33 billion.
The latest wealth surge follows a period of rapid appreciation. Musk first crossed the $500 billion threshold in October 2024, driven by Tesla’s stock performance. By mid-December, a private valuation of SpaceX at $800 billion pushed his net worth beyond $600 billion. Days later, a Delaware Supreme Court ruling reinstated his Tesla stock options, lifting his total wealth above $700 billion.
The consolidation of his leading technology ventures under a single corporate umbrella has crystallized Musk’s financial position at an unprecedented level, highlighting the escalating market value assigned to private aerospace and AI enterprises. His current fortune is intrinsically linked to the future performance and valuation of the merged SpaceX-xAI entity, alongside Tesla’s trajectory.
