Elon Musk, the United States-based technology entrepreneur and founder of multiple global companies, has officially become the first individual in world history to surpass a net worth of $600 billion, marking a watershed moment in modern wealth accumulation.
According to updated estimates released by Forbes, Musk’s total wealth stood at $677 billion as of 12:00 p.m. United States Eastern Time on Monday, placing him far beyond any other billionaire on record.
Okay News reports that the dramatic rise in Musk’s fortune is largely tied to a sharp upward revaluation of his private aerospace firm, SpaceX, which has emerged as the most valuable privately held space company in the world.
Earlier in December 2025, SpaceX concluded a major internal tender offer that valued the company at $800 billion, a figure that represents a full doubling of its $400 billion valuation recorded in August 2025, according to investors familiar with the transaction and cited by Forbes.
Musk is estimated to own 42 percent of SpaceX, and the revised valuation alone added approximately $168 billion to his personal net worth, further solidifying his position as the world’s richest individual.
The tender offer comes at a time when SpaceX is reportedly preparing for a potential Initial Public Offering in 2026, with one investor suggesting that the company could command a market valuation of around $1.5 trillion if it lists publicly. Such a development would likely propel Musk into unprecedented territory as the world’s first trillionaire, even without factoring in gains from his other business holdings.
Beyond SpaceX, Musk’s wealth portfolio remains diversified across several high-value technology ventures. Forbes estimates that his $336 billion stake in SpaceX now exceeds the value of his 12 percent ownership in Tesla, which is currently worth about $197 billion.
In addition, stock options tied to Musk’s 2018 Tesla Chief Executive Officer performance award, which were voided by a Delaware judge in January 2024, have been discounted to $69 billion pending the outcome of his appeal before the Delaware Supreme Court.
Musk’s artificial intelligence company, xAI Holdings, has also become a significant contributor to his expanding fortune. The company is reportedly in the process of raising fresh capital at a valuation of $230 billion, more than double the $113 billion valuation Musk referenced in March 2025 when xAI was formed through a merger with his social media platform, X. Musk controls 53 percent of xAI Holdings, a stake currently valued at approximately $60 billion.
With an estimated $425 billion gap separating Musk from the world’s second-richest individual, Larry Page of Google, Forbes emphasized that Musk is now closer to reaching $700 billion than facing any realistic threat to his position at the top of the global wealth rankings.
