- Why the World’s Top 10 Richest Person Rankings Shifted
- Tech Billionaires Dominate Top 10 Richest List
At the start of this year, the global wealth rankings felt familiar. By December, they told a very different story. Yes, Elon Musk still sits comfortably at the top as the world’s richest man. That part did not change. But almost everything else did.
The Bloomberg Billionaires Index shows that the top 10 richest person in the world list quietly reshuffled as AI rewired market leadership, technology wealth compounded faster than expected, and some long-standing names struggled to keep up.
The biggest surprise was not who topped the list, but who climbed aggressively, who slipped despite getting richer, and who dropped out altogether. The world richest man 2025 debate turned into a broader question.
Where exactly did money grow fastest this year, and why? The answer lies in AI, ownership structure, and timing. Let’s break down what happened with the world’s richest billionaires in 2025.
What World’s Top 10 Richest Ranking Represents
The ranking tracks individual net worth, updated daily by the Bloomberg Billionaires Index. Net worth includes listed equity holdings, private company valuations, cash, and other disclosed assets. Changes reflect stock prices and valuation shifts, not income or cash generation.
In simple terms, the richest person in the world list shows where markets rewarded ownership in 2025.

Elon Musk’s Net worth remains Untouched
Despite having a volatile year where his net worth swung wildly due to Tesla stock movement, Elon Musk not only managed to retain his spot as the world’s richest man but also developed a healthy gap to others in the list.
Elon Musk’s net worth briefly touched the $500 billion mark, making him the first person in history to reach this half-trillion figure. This was fueled by Tesla’s rebound, soaring private valuations at SpaceX, and the rising profile of his AI venture, xAI.
Tesla, however, remains Musk’s biggest wealth driver as he owns around 13% of the company and any movement in Tesla share price, causes major shifts in Elon Musk’s net worth.
Why the World’s Top 10 Richest Person Rankings Shifted
The reshuffle followed capital, not headlines.
AI Changed the Math for Tech Founders
The biggest movers of 2025 were founders with heavy ownership in AI-exposed companies.
- Google co-founders Larry Page and Sergey Brin saw the sharpest gains. Alphabet’s earnings and filings showed improving search monetisation, better Google Cloud margins, and tighter cost control. AI optimism lifted valuations pushing the company close to $4 trillion market cap, and founder ownership did the rest.
- Larry Ellison moved up as Oracle surprised markets. Its cloud infrastructure business, now increasingly tied to AI workloads, delivered better revenue visibility. That was enough for a meaningful re-rating. He even managed to dethrone Elon Musk for a few hours to become the world’s richest person on September 10.
Jeff Bezos’ Net Worth Grows But Rank Slips
Jeff Bezos’ net worth still grew. Amazon’s earnings reflected stabilising AWS margins and healthier retail cash flows. But Amazon is already massive. Percentage gains were smaller, which is why Bezos slipped in rank despite being richer.
The same story played out at Meta. Mark Zuckerberg’s net worth rose steadily as advertising efficiency improved and AI spending stayed disciplined. Strong performance, but not enough to outrun faster-moving peers.
Nvidia Stock Surge Propels Jensen Huang in Top 10
One of the clearest changes in 2025 was the rise of Jensen Huang. Nvidia’s data centre revenue surged on sustained AI chip demand. As the market priced in longer-term AI infrastructure spending, NVDA stock surged making Nvidia the first company in the world to touch $5 trillion market cap.
As a result of this Jensen Huang’s net worth climbed fast enough as he holds 3.5% to 3.8% stake in the semiconductor firm landing him among the top 10 richest persons in the world by December.
Warren Buffett Exits World’s Top 10 Richest
The most symbolic shift in the list was Warren Buffett’s exit. Berkshire Hathaway remained profitable, but filings showed elevated cash levels and limited exposure to AI-driven stocks. In a year where markets rewarded acceleration over preservation, Buffett’s approach simply compounded slower.
While Warren Buffett’s net worth jumped by around $7 billion this year, he ended December ranked just outside the top 10 richest persons in the world, not because of losses, but because others moved faster.
Tech Billionaires Dominate Top 10 Richest List
By December, technology dominated global wealth.
- Nine of the top ten billionaires were tied to technology companies
- AI platforms, cloud infrastructure, and digital advertising drove valuation expansion
- Founder-heavy ownership amplified net worth swings
The richest country in the world by billionaire concentration remained the United States as 9 out of top 10 billionaires are from the US, reflecting how US tech markets continue to dominate wealth creation.
Luxury, led by LVMH, lagged. Demand recovery in Asia was slower, and margins normalised, limiting upside for Bernard Arnault. However, the French billionaire held on to a place among the top 10 richest people in the world.
