Elon Musk, the CEO of Tesla, briefly became the first person in history to cross the $500 billion net worth milestone, according to Bloomberg’s Billionaires Index. The landmark achievement came after a surge in Tesla’s share price, before dropping slightly below the figure hours later.
On Wednesday, Tesla stock rose 3.3%, pushing Musk’s net worth above $500 billion (£370bn), before settling back at $470 billion (£348bn) by the close of the New York Stock Exchange. The Bloomberg Index, which tracks the wealth of the world’s 500 richest individuals, showed Musk’s wealth jumping by more than $10.5 billion in a single day.
For context, many billionaires on the list hold less than $10 billion, meaning Musk’s one-day increase was larger than the total net worth of 159 billionaires in Bloomberg’s global rankings.
Elon Musk’s Business Empire
In addition to Tesla, Musk owns:
- SpaceX 🚀
- The Boring Company
- xAI (artificial intelligence venture)
Some of these private companies have seen their valuations rise in 2025, further boosting Musk’s wealth outlook.
Will Musk Become the First Trillionaire?
Musk currently owns around 12–13% of Tesla, but future performance-based payouts could increase his stake significantly. Analysts suggest that if Tesla continues to achieve its milestones, Musk could potentially become the world’s first trillionaire.
Shares of Tesla have jumped more than 70% in the past six months, despite sales challenges in Europe and growing competition from Chinese EV companies. While the stock remains slightly below its record high of December 2024, investor confidence continues to push valuations upward.
Competition at the Top
Just weeks ago, Musk briefly lost his title as the world’s richest person to Larry Ellison, CEO of Oracle, after a major surge in Oracle’s stock price. However, Musk has since widened the gap again, holding a $121 billion lead over Ellison. To put this in perspective, this gap alone equals the entire fortune of Bill Gates, who sits at 15th place among global billionaires.
Conclusion
Elon Musk’s wealth journey highlights how closely tied billionaire fortunes are to stock market movements. With Tesla’s performance, SpaceX’s rising valuation, and his expanding AI ventures, Musk’s climb toward trillionaire status seems increasingly possible.
