Why do technology and AI dominate the wealth of the world's richest men in 2025?

The billionaire ranking always reflects the state of the global economy, and 2025 is no exception. The latest list from the Bloomberg Billionaires Index sends a clear message: those who control technology, artificial intelligence, and digital innovation amass the largest fortunes on the planet. Among the top 10 billionaires, nine are North American, consolidating the US dominance in the tech sector.

The Undisputed Leadership of Elon Musk

With a net worth exceeding US$ 358 billion, Elon Musk remains at the top. His wealth does not come from a single business — Tesla, SpaceX, xAI, and the X platform serve as interdependent pillars of an expanding empire. Musk also holds positions in digital assets such as Bitcoin (currently valued at US$ 87.91K), Ethereum (US$ 2.95K), and Dogecoin (US$ 0.13), diversifying his exposure to the crypto ecosystem.

The Immediate Competitors: Larry Ellison and Mark Zuckerberg

Right behind, Larry Ellison (US$ 251 billion) and Mark Zuckerberg (US$ 251 billion) share the second position. Ellison built his empire through Oracle, dominating the database and cloud computing markets. Zuckerberg, in turn, expanded his reach through Meta, controlling a digital ecosystem that spans traditional social networks (Facebook, Instagram, WhatsApp), and emerging technologies like virtual reality and the metaverse.

The Retail Revolution: Jeff Bezos

Jeff Bezos (US$ 247 billion) remains among the top three, a result of his ability to transform global retail. Amazon Web Services has established itself as one of the largest cloud computing platforms, while his space exploration company, Blue Origin, represents an investment in future sectors.

Other Pillars: From Cloud Computing to Artificial Intelligence

Steve Ballmer (US$ 174 billion), former CEO of Microsoft, was instrumental in the company’s growth in areas like Azure and Office, critical sectors for global digital infrastructure.

Larry Page (US$ 165 billion), co-founder of Google, maintains decisive influence in AI, aerospace technology, and autonomous vehicles — sectors shaping the future.

Bernard Arnault (US$ 156 billion) is the only European among the top ten. Leading the LVMH group, he controls the most coveted luxury brands in the world — Louis Vuitton, Dior, Moët & Hennessy — proving that wealth also flourishes outside of technology.

Sergey Brin (US$ 154 billion), also a Google co-founder, invests heavily in autonomous mobility and biotechnology, betting on disruptive trends.

Jensen Huang (US$ 149 billion) is the biggest recent growth story. Creator of NVIDIA, his GPUs have become essential infrastructure for data centers, machine learning, and AI — the economic engine of 2025.

Warren Buffett (US$ 141 billion), the “Oracle of Omaha,” remains an absolute reference in value investing through Berkshire Hathaway, proving that discipline and patience still win.

Why Do These Sectors Dominate?

The concentration of wealth in technology, AI, and cloud computing is no accident. These sectors offer:

• Extreme scalability — a digital solution can serve billions of users simultaneously • High margins — software and cloud services generate recurring revenue and low operational costs • Network effect — the more users, the more valuable the platform • Growing demand — AI, cloud, and autonomous mobility will shape the next decade

Lessons for Investors Studying the Names of Millionaires

Analyzing how the biggest billionaires accumulate wealth offers strategic insights:

Thematic diversification — Musk does not invest in everything but in complementary sectors (energy, technology, space). Zuckerberg focuses on the digital ecosystem.

Investing in emerging trends — Jensen Huang rode the wave of AI; Larry Page anticipated AI and autonomy; Buffett identifies undervalued assets decades before the market recognizes them.

Platform control — most control ecosystems that define markets, not just products. Amazon does not just sell physical goods; it offers infrastructure. Meta not only connects people; it builds metaverses.

Long-term patience — all these names think in decades, not quarters.

For investors seeking inspiration, the message is doubled: identify transformational sectors, build long-term positions, diversify strategically, and follow giants of technology and innovation — they will continue to generate the largest fortunes on the planet.
