The Intense Competition for the Top of the Billionaires Ranking Has a Familiar Name Back in the Lead, Driven by the Appreciation of Their Technology Companies.
According to Forbes’ real-time billionaires list, the intense competition for the global ranking has a familiar name back in the lead. In mid-2025, Elon Musk, the visionary behind Tesla and SpaceX, is again the richest person in the world. His fortune, driven by innovation and a volatile market, once again places him ahead of names like French luxury magnate Bernard Arnault and Amazon founder Jeff Bezos.
The rise and constant fluctuations atop global wealth rankings are a barometer of the economy and the stock market. Musk’s fortune is intrinsically linked to the performance of his technology companies, which have experienced significant valuations. This dynamic sets him apart from more traditional fortunes, such as Arnault’s, consolidated in the resilient luxury goods sector with the LVMH conglomerate.
The Fortune Behind the Technology Visionary
Elon Musk has solidified his position as the richest person in the world with a net worth that, according to Forbes in July 2025, exceeds US$ 400 billion. The main source of his wealth comes from his equity holdings in two revolutionary companies: Tesla, a giant in electric vehicles, and SpaceX, a pioneer in private space exploration.

In addition to these, Musk leads other ambitious ventures, such as the neurotechnology company Neuralink and The Boring Company, focused on infrastructure and tunneling. His moves in the market, including the acquisition and transformation of Twitter into “X”, also directly impact perceptions of his wealth.
The Game of Musical Chairs at the Top of the Billionaires
The title of richest person in the world has been intensely contested in recent years. Bernard Arnault, chairman and CEO of LVMH (owner of brands like Louis Vuitton, Dior, and Sephora), even held the top position, especially during periods when technology stocks were falling. In April 2024, for example, Arnault led the list with an estimated net worth of US$ 233 billion.
However, volatility is the rule. Jeff Bezos, who dominated the ranking for years thanks to Amazon’s success, and other tech names like Larry Ellison (Oracle) and Mark Zuckerberg (Meta), continue to feature at the top of the list, their fortunes fluctuating according to their companies’ results and investor sentiment.
How Is Billionaires’ Wealth Measured?
To understand who the richest person in the world is, it is crucial to know how this wealth is calculated. Publications like Forbes and Bloomberg maintain indices that track billionaires’ wealth in real time. The methodology is primarily based on the value of publicly traded companies’ stocks that they own.
The majority of the wealth is not cash in the bank, but rather the value of their assets. Therefore, the ranking is extremely dynamic. A single trading session on the stock market can increase or decrease a billionaire’s fortune by billions of dollars. The values of private companies, such as Musk’s SpaceX, are estimated based on funding rounds and comparisons with similar publicly traded companies.
What Musk’s Leadership Reveals
The predominance of figures from the technology sector, with Elon Musk at the top, reinforces the importance of innovation and disruption in today’s markets. Unlike inherited fortunes or those built in traditional sectors, wealth in the 21st century is increasingly tied to the ability to create and dominate new technological frontiers, whether in artificial intelligence, energy transition, or the new space race. The constant swapping of positions at the top of the richest person in the world list is a direct reflection of this era of rapid transformations.
