Elon Musk has made history again. The Tesla and SpaceX chief has become the first person in the world to cross a net worth of $500 billion, as reported by Forbes’ Real-Time Billionaires Index on 1 October 2025.
The milestone cements Musk’s place as the richest individual on the planet, with his fortune now greater than the GDP of several nations, including Austria and Norway. It also reflects the astonishing rise of technology-driven wealth in today’s markets.
Tesla’s Stock Surge and AI Bets Push Musk Past the Milestone
The record-breaking number came on the back of a strong rally in Tesla’s share price, which jumped more than 3% on Tuesday, adding about $6 billion to Musk’s personal fortune in a single day, according to Reuters.
Musk, who owns roughly 12.4% of Tesla, has seen his wealth soar in recent months thanks to investor optimism around the company’s advancements in AI-powered vehicles and robotics. His other ventures, SpaceX and xAI, have also grown rapidly in value, with SpaceX now reportedly worth over $250 billion.
Adding to investor confidence, Musk himself purchased $1 billion worth of Tesla shares in September, signalling that he continues to back the company’s long-term vision despite a competitive EV market.
A Landmark Moment, But Mostly on Paper
While Musk’s half-trillion-dollar net worth is a landmark moment, experts point out that the figure represents “paper wealth”, not liquid assets. Most of his fortune is tied up in shares of Tesla and privately held companies such as SpaceX and xAI.
The Bloomberg Billionaires Index still values him at around $383 billion, illustrating how wealth estimates can differ widely based on market performance and valuation methods.
Analysts warn that Musk’s fortune could fluctuate sharply with Tesla’s stock price, given that the company operates in a highly competitive sector. Slower EV sales or regulatory challenges in key markets could pull down his wealth as quickly as it has risen.
That said, Tesla’s board recently approved a $29 billion stock award for Musk, linked to ambitious growth and performance goals, a strong sign of confidence from the company’s leadership in his long-term vision.
Is the World’s First Trillionaire Next?
Musk’s latest milestone has inevitably sparked speculation about whether he could become the first-ever trillionaire. Analysts say it’s possible, but not imminent.
For Musk to reach that level, Tesla would need to continue expanding its global market share, SpaceX would have to scale commercial space ventures profitably, and xAI would need to establish itself as a dominant force in artificial intelligence.
Even by Musk’s ambitious standards, that’s a tall order. Yet, given his track record from revolutionising the auto industry to commercialising space travel, few are betting against him.
Final Thoughts
Elon Musk’s $500 billion milestone is not just a personal record, it is a reflection of how modern wealth is shaped by technology, innovation, and market confidence. Whether this is the peak of his financial journey or just another step on his path to becoming the world’s first trillionaire, Musk continues to redefine what’s possible for entrepreneurs in the 21st century.
