Elon Musk, Chief Executive Officer of SpaceX, Tesla, and xAI, has reached a new personal wealth milestone, surpassing a net worth of $600 billion, driven primarily by a recent valuation increase of SpaceX.
The development makes Musk the first individual in history to exceed the US$600 billion threshold.
According to Bloomberg’s Billionaires Index, Musk’s net worth stood at approximately $638 billion as of 15 December 2025, with the increase largely attributed to SpaceX, which was recently valued at around $800 billion following an insider share sale.
The privately held aerospace company, based in Starbase, Texas, is now considered the most valuable private firm globally, significantly boosting Musk’s personal holdings.
Musk’s stake in Tesla, estimated at roughly 12 per cent, is valued at nearly $200 billion, while his majority ownership of xAI Holdings is estimated at $60 billion.
Collectively, these assets place him on track to potentially approach US$700 billion, widening the gap between him and the world’s second-richest individual, former Google CEO Larry Page, valued at $265 billion.
The SpaceX valuation comes ahead of a projected public listing in 2026, which could see the company valued at approximately $1.5 trillion.
“Other shareholder meetings are snooze-fests but ours are bangers. Look at this. This is sick,” Musk said in November during Tesla’s shareholder meeting, referring to a performance-linked pay package approved by investors.
He added, “I super appreciate it.” The package, potentially worth up to US$1 trillion in stock, is tied to market-capitalisation and operational milestones over the next decade.
SpaceX’s Starlink satellite network has also contributed to investor confidence. The company continues to expand high-speed internet access to underserved regions worldwide.
Chad Gibbs, Vice President of Starlink Operations, stated that the satellite technology “bypasses the need to build massive amounts of infrastructure,” allowing broader and faster connectivity.
Musk’s ascent in personal wealth follows years of strategic risk-taking and long-term planning, with Tesla’s focus on electric vehicles, battery technology, and autonomous systems laying the foundation for his financial growth.
Analysts note that the combination of SpaceX’s soaring valuation, Tesla’s long-term incentives, and Musk’s diverse portfolio underpins his current status as the world’s wealthiest individual
