Entrepreneur Becomes The First Person To Reach The Half-Trillion-Dollar Milestone, Driven By The Strong Rise Of Tesla Shares And The Appreciation Of Companies Like SpaceX And xAI.
According to data gathered by Interesting Engineering, Elon Musk is not only the richest person in the world in October 2025 but also the first human in history to achieve a net worth of US$ 500 billion. The milestone was reached after an exceptionally positive September for the technology sector, which consolidated the fortune of the CEO of Tesla and SpaceX at an unprecedented level, further distancing him from other billionaires on the global ranking.
The financial landscape for the global elite has been extremely favorable. Driven by investor optimism about artificial intelligence (AI) and robotics, the 10 richest billionaires on the planet collectively added over US$ 200 billion to their fortunes just in September. Together, this select group now controls an impressive capital of US$ 2.3 trillion, reflecting an ever-increasing concentration of wealth tied to technological innovation.
Musk’s Ascent: How The CEO Of Tesla Built Half A Trillion Dollars?
The main driving force behind Elon Musk’s record was the spectacular performance of Tesla shares, which skyrocketed 33% in September. According to analysis by Interesting Engineering, this growth was fueled by market enthusiasm around the company’s advances in AI and robotics, alongside a strategic move by Musk himself, who purchased US$ 1 billion in shares, reinforcing investor confidence in the company’s future. Currently, the electric car manufacturer has a market valuation over one trillion dollars.

However, the entrepreneur’s fortune does not depend solely on Tesla. His other ventures have proven equally crucial in reaching the US$ 500 billion mark. SpaceX, his aerospace company, saw its market value leap to US$ 400 billion after a private offering in August 2025. At the same time, the artificial intelligence startup xAI had its valuation raised to US$ 80 billion, according to Musk himself, following a funding round that raised US$ 6 billion from private investors. This diversification of assets in cutting-edge sectors solidifies his dominant position.
The Pantheon Of Billionaires: Who Accompanies Musk At The Top?
Although Elon Musk has isolated himself in the lead, other technology titans have also seen their fortunes grow significantly. In second place in the ranking is Larry Ellison, co-founder and chairman of Oracle, with an estimated net worth of US$ 350.7 billion. Ellison’s leap was driven by an optimistic forecast from Oracle, projecting a 700% increase in revenue from its cloud infrastructure division, primarily due to advances in AI. This projection caused the company’s stock to rise 36% in a single day.
Next is Mark Zuckerberg, CEO of Meta Platforms, with a fortune of US$ 254.7 billion. Even with the challenges in the transition to the “metaverse”, the robust advertising revenue from platforms like Facebook, Instagram, and WhatsApp sustains his position. Currently, Zuckerberg is focused on superintelligent AI projects, massively investing in data centers and recruiting top talent to compete at the forefront of AI. Jeff Bezos, founder of Amazon, holds the fourth position with US$ 232.5 billion, remaining a central figure in the global landscape.
The Market In October 2025: Gains And Losses In The Global Elite
The month of September, as reported by Interesting Engineering, was a period of significant gains for most billionaires at the top of the list, but not for everyone. While Elon Musk and Larry Ellison dominated the profits, Jensen Huang, CEO of Nvidia, also saw his fortune grow significantly, reaching US$ 162 billion and seventh position. Huang’s success is directly linked to the meteoric rise of Nvidia’s AI chips, which led the company to a market capitalization of US$ 4.5 trillion.
On the other hand, names like Jeff Bezos, Mark Zuckerberg, and Warren Buffett (tenth on the list with US$ 150.2 billion) ended the month with somewhat lighter pockets, highlighting the volatility of the market, even for the richest. The “Oracle of Omaha”, at 95 years old, continues to lead Berkshire Hathaway but plans to retire at the end of 2025. The list of the 10 richest is completed by figures like Larry Page (US$ 202.2 billion), Sergey Brin (US$ 187.6 billion), Bernard Arnault (US$ 159.4 billion), and Steve Ballmer (US$ 156 billion).
Musk’s rise to an unprecedented level of wealth marks a new chapter in the global economy, where technology and artificial intelligence consolidate as the main vectors of capital.
