Elon Musk Surpasses $800 Billion Following Historic SpaceX-xAI Merger

Elon Musk has made history by becoming the first individual to surpass a net worth of $800 billion, following the completion of SpaceX's acquisition of the artificial intelligence and social media company xAI, which he also owns.
According to Forbes estimates, the deal, which values the combined entity at $1.25 trillion, has raised Musk's fortune to $852 billion, making SpaceX the most valuable asset in his portfolio by a significant margin.
Prior to the merger, Musk held approximately 42% of SpaceX shares, valued at around $336 billion, based on a previous buyout offer that valued the company at $800 billion.
His stake in xAI was also around 49%, worth $122 billion, following a funding round that assessed the company at $250 billion earlier this month.
After the merger, Musk's share in the unified company stands at 43%, valued at about $542 billion.
Musk's portfolio also includes a 12% stake in Tesla, valued at $178 billion, in addition to stock options worth $124 billion.
These estimates do not account for standard compensations that could potentially grant Musk up to $1 trillion more if he meets Tesla's ambitious targets, including increasing its market value more than eightfold over the next decade.
Notably, this merger marks the second time in less than a year that Musk has combined two of his companies; in March, xAI merged with the social media platform X (formerly Twitter), in a deal that valued xAI at $80 billion and X at $33 billion, a figure close to what he paid for Twitter in 2022.
In just four months, Musk has achieved four record milestones in his net worth:
• October: Surpassed $500 billion.
• December 15: Surpassed $600 billion following a private investor valuation of SpaceX at $800 billion.
• Four days later: Surpassed $700 billion after the Supreme Court's decision to reinstate Tesla's stock options.
As a result, Musk has become wealthier than the second-richest person in the world, Larry Page, by an estimated $578 billion, with Page's fortune estimated at around $281 billion. Musk is now on track to potentially become the world's first trillionaire, needing approximately "half of Larry Page's" wealth to reach that milestone.
