Elon Musk’s personal fortune has climbed sharply following a substantial funding round for xAI Holdings, the artificial intelligence and social media venture he leads, bringing his estimated net worth close to US$800 billion. According to Forbes’s Real‑Time Billionaires List, Musk’s wealth now stands at about $780 billion, driven in large part by the recent valuation boost for xAI.
Private investors injected approximately $20 billion into xAI in early January 2026, valuing the company at US$250 billion — more than double the figure attributed to it less than a year ago. That surge in valuation added roughly US$62 billion to the value of Musk’s 49 percent ownership stake in the company, now estimated at about US$122 billion.
The fresh capital round follows the merger of xAI with Musk’s social media platform X (formerly Twitter) in March 2025, an all‑stock deal that initially valued the combined entity at around US$113 billion. xAI’s growth and expanded investor interest reflect broader momentum in the artificial intelligence sector, where large funding rounds have become increasingly common.
Musk’s ascent toward the US$800 billion mark also reflects gains in his other major holdings. SpaceX, the rocket and satellite company he founded, has seen its private valuation rise to approximately US$800 billion in recent tender offers, making it one of the most valuable private companies globally. Musk owns an estimated 42 percent stake in SpaceX, giving that asset a roughly US$336 billion valuation contribution to his net worth.
Tesla, where Musk holds both common shares and stock options, remains another significant component of his fortune, with combined holdings valued at around US$307 billion.
The convergence of high valuations in xAI, SpaceX, and Tesla has propelled Musk to the top of the global wealth rankings, maintaining his position as the richest person in the world. This milestone places him on track to potentially become the first individual with a net worth of $800 billion or more once holdings and market conditions continue to evolve.
