Bloomberg Billionaires Index statistics at a glance
The Bloomberg Billionaires Index is built for daily movement, so the interesting part is not just who is rich, but how quickly the ranking changes when markets move. It covers 500 of the world’s richest people and updates after the close of trading in New York, which makes it a live snapshot of wealth tied to public markets, private company marks, and exchange rates (Bloomberg Billionaires Index methodology).
Quick takeaways
- The index tracks the world’s 500 richest people and updates every business day after the New York market close (Bloomberg Billionaires Index methodology).
- Public-company stakes are valued at the most recent closing price, while currency conversion uses current exchange rates (Bloomberg Billionaires Index methodology).
- Closely held companies typically receive a 5% liquidity discount in the standard methodology (Bloomberg Billionaires Index methodology).
- Each billionaire profile includes a confidence rating from 1 star to 5 stars (Bloomberg Billionaires Index methodology).
- The top page snapshot in the dataset shows Elon Musk at number 1 with $651 billion, followed by Larry Page at $325 billion and Sergey Brin at $301 billion (Bloomberg Billionaires Index top page).
- The richest 500 people added a record $2.2 trillion in wealth in 2025, lifting collective net worth to $11.9 trillion (Bloomberg Billionaires Index - 500 mayores fortunas crecen un récord US$2,2 billones en 2025).

How the index is built
The Bloomberg Billionaires Index is structured as a daily ranking of 500 people, and that number matters because it sets the boundary for inclusion and the pace of change in the list (Bloomberg Billionaires Index methodology; Bloomberg Billionaires Index top page).
A few methodology points shape how the rankings should be read:
- Public company ownership is marked using the latest closing price available in the market (Bloomberg Billionaires Index methodology).
- Foreign currency holdings and non-U.S. asset values are converted into U.S. dollars using current exchange rates (Bloomberg Billionaires Index methodology).
- The standard liquidity discount for most closely held companies is 5%, which is a reminder that not every private stake is treated as if it could be sold instantly at headline value (Bloomberg Billionaires Index methodology).
- Each profile carries a confidence rating from 1 star to 5 stars, so the index signals how solid the underlying estimate is rather than pretending every number has the same certainty (Bloomberg Billionaires Index methodology).
That framework explains why the index often feels less like a static rich list and more like a market instrument. It is measuring fortune through assets, liquidity assumptions, and timing, not just naming people who are wealthy.
What the top page shows now
The snapshot in the dataset gives a clear picture of the current top tier. The top six are packed with technology founders, and the distance between each rank is large enough to make the leaderboard feel surprisingly concentrated at the top (Bloomberg Billionaires Index top page).
| Rank | Person | Net worth | Last change | YTD change | Country / region | Industry |
|---|---|---|---|---|---|---|
| 1 | Elon Musk | $651B | +$6.33B | +$31.5B | United States | Technology |
| 2 | Larry Page | $325B | +$27.1B | +$55.5B | United States | Technology |
| 3 | Sergey Brin | $301B | +$25.0B | +$51.3B | United States | Technology |
| 4 | Jeff Bezos | $283B | +$1.73B | +$29.8B | United States | Technology |
| 5 | Mark Zuckerberg | $217B | -$19.9B | -$16.4B | United States | Technology |
| 6 | Larry Ellison | $213B | not listed in dataset | not listed in dataset | not listed in dataset | not listed in dataset |
That table shows two immediate patterns. First, the top five are all U.S.-based and tied to technology (Bloomberg Billionaires Index top page). Second, the gaps are not small: Elon Musk’s $651 billion is nearly double Larry Page’s $325 billion on the same snapshot, and Page still sits only two ranks ahead of Sergey Brin at $301 billion (Bloomberg Billionaires Index top page).
The day-over-day numbers also show that the ranking is not frozen. Larry Page’s +$27.1 billion and Sergey Brin’s +$25.0 billion are huge moves even by billionaire-index standards, while Mark Zuckerberg’s -$19.9 billion shows how quickly a large fortune can swing in the opposite direction (Bloomberg Billionaires Index top page).
Ranking patterns among the top names
The top page snapshot is useful because it does not just tell you who is richest; it shows what kind of wealth dominates the list. The dominant pattern is technology concentration, with six of the top six names tied to technology in the snapshot, and the next several profile pages reinforcing the same theme through the largest asset and business descriptions (Bloomberg Billionaires Index top page).
The top three are unusually close as a cohort
Elon Musk is first at $651 billion, but the more interesting point is the cluster underneath him. Larry Page at $325 billion and Sergey Brin at $301 billion are both above the $300 billion mark, and Jeff Bezos follows at $283 billion (Bloomberg Billionaires Index top page). That means the top four combine to form a very dense wealth band, even though each one is still separated by tens of billions of dollars.
A useful way to read this is that the index top is not just a list of isolated fortunes. It is a market-priced leaderboard in which multiple people can gain or lose tens of billions in a short period without changing the basic shape of the list.
The biggest daily movers matter as much as the absolute ranks
On the snapshot in the dataset, Larry Page posted a +$27.1 billion daily change and Sergey Brin posted +$25.0 billion, both of which are striking increases relative to a single update cycle (Bloomberg Billionaires Index top page). By contrast, Mark Zuckerberg’s -$19.9 billion daily move makes him the clearest example in the top five of a major negative swing (Bloomberg Billionaires Index top page).
These movements matter because the index is updated every business day. A name can hold its rank while still seeing a large wealth swing, and the swing itself often tells the more important story about market exposure and asset concentration (Bloomberg Billionaires Index methodology).
What the profile pages reveal
The profile snapshots are where the index becomes more useful than a bare ranking. They tie each person’s wealth to a major asset, an age, and sometimes a concrete operating metric from the business that anchors the fortune (Bloomberg Billionaires Index profile pages cited in dataset).
Selected profile facts in one view
| Person | Rank | Age | Biggest asset | Notable profile fact |
|---|---|---|---|---|
| Warren Buffett | 10 | 95 | BRK/A US Equity | Berkshire Hathaway has delivered a 19.9% compounded annual gain in market value since 1965 (Bloomberg Billionaires Index - Warren Buffett) |
| Bernard Arnault | 7 | 76 | not listed in dataset | LVMH reported revenue of 84.7 billion euros in 2024, shown as $91.6 billion on the profile (Bloomberg Billionaires Index - Bernard Arnault) |
| Steve Ballmer | 8 | 69 | MSFT US Equity | Microsoft stake last disclosed as 333 million shares in the 2014 proxy (Bloomberg Billionaires Index - Steve Ballmer) |
| Jensen Huang | 11 | 63 | not listed in dataset | Nvidia reported revenue of $130.5 billion in the year to Jan. 26, 2025; he owns about 3.3% of Nvidia according to a December 2025 filing (Bloomberg Billionaires Index - Jensen Huang) |
| Larry Page | 2 | 52 | GOOG US Equity | Alphabet reported revenue of $350 billion in 2024; stake described as about 6% of Alphabet (Bloomberg Billionaires Index - Larry Page) |
| Sergey Brin | 3 | 52 | GOOG US Equity | Alphabet reported revenue of $350 billion in 2024; owns about 6% of Alphabet (Bloomberg Billionaires Index - Sergey Brin) |
| Jeff Bezos | 4 | 61 | AMZN US Equity | Amazon had revenue of $638 billion in 2024 (Bloomberg Billionaires Index - Jeff Bezos) |
| Mark Zuckerberg | 5 | 41 | META US Equity | Meta had more than 3 billion daily users and about 13% of Meta Platforms (Bloomberg Billionaires Index - Mark Zuckerberg) |
The table makes one thing obvious: the index often links wealth to concentrated ownership in giant businesses. That is not just descriptive. It explains why these fortunes move so much when the underlying stock or private valuation shifts.
Buffett and Arnault show different wealth structures
Warren Buffett’s profile is a useful contrast because his wealth is tied to Berkshire Hathaway, and the profile notes that Berkshire has delivered a 19.9% compounded annual gain in market value since 1965 (Bloomberg Billionaires Index - Warren Buffett). That is a long-duration compounding story rather than a fast-moving founder equity story. His rank is 10 with $154 billion on the November 14, 2025 profile snapshot, and his biggest asset is BRK/A US Equity (Bloomberg Billionaires Index - Warren Buffett).
Bernard Arnault’s profile is different again. He is ranked 7 with $202 billion on the November 14, 2025 profile snapshot, age 76, and LVMH reported 84.7 billion euros in revenue in 2024, shown as $91.6 billion on the profile (Bloomberg Billionaires Index - Bernard Arnault). That makes his wealth story feel less like a single-stock founder narrative and more like a luxury-goods empire with a clearly stated operating base.
Ballmer and Huang show the value of concentrated stakes
Steve Ballmer’s profile says his biggest asset is MSFT US Equity, his age is 69, and his Microsoft stake was last disclosed as 333 million shares in Microsoft’s 2014 proxy (Bloomberg Billionaires Index - Steve Ballmer). The profile also notes that he is calculated to have sold 14 million Microsoft shares to cover almost one-third of the $2 billion purchase price of the Los Angeles Clippers (Bloomberg Billionaires Index - Steve Ballmer). That is an example of how one large purchase can become part of the wealth narrative for years.
Jensen Huang’s profile shows another version of concentrated wealth. He is rank 11 with $142 billion on the March 26, 2026 snapshot, age 63, and Nvidia reported revenue of $130.5 billion in the year to Jan. 26, 2025 on his profile (Bloomberg Billionaires Index - Jensen Huang). The profile also says he owns about 3.3% of Nvidia according to a December 2025 filing (Bloomberg Billionaires Index - Jensen Huang). That combination of a relatively small percentage ownership and a massive public-company valuation is exactly the kind of setup the index is designed to capture.
Recent wealth-change records
The dataset includes several milestone figures that help explain why Bloomberg’s billionaire coverage attracts attention beyond the rank list itself. These are not just high numbers. They are records or near-record movements that show how large-scale wealth is tied to market conditions.
A record one-day jump
The largest one-day gain in the history of the index was $304 billion on April 9, 2025 (Bloomberg Billionaires Index - Billionaires Score Best-Ever Day as Stocks Soar on Tariff Pause). That single day lifted the 500 richest people by an average 3.5%, and Elon Musk was the biggest individual gainer with $36 billion (Bloomberg Billionaires Index - Billionaires Score Best-Ever Day as Stocks Soar on Tariff Pause).
That kind of move is important because it shows that billionaire wealth can respond to macro events at a scale that is itself record-setting. The index is therefore not just a ranking of people; it is a record of how markets transmit value into personal net worth.
A record year for the entire top 500
The richest 500 people added a record $2.2 trillion in wealth in 2025, and that pushed their collective net worth to $11.9 trillion (Bloomberg Billionaires Index - 500 mayores fortunas crecen un récord US$2,2 billones en 2025). The dataset also says eight people accounted for a quarter of that growth (Bloomberg Billionaires Index - 500 mayores fortunas crecen un récord US$2,2 billones en 2025).
That is a major concentration signal. It means the gains were not spread evenly across the full 500-person group, but were heavily skewed toward a very small number of ultra-large fortunes.
What the top names suggest about concentration
The snapshot and the record data point in the same direction. The very top names are not just wealthy, they are disproportionately responsible for movement in the full index. Musk’s $651 billion, Page’s $325 billion, Brin’s $301 billion, Bezos’s $283 billion, and Zuckerberg’s $217 billion make clear that the upper end of the index is dominated by a small number of extremely large, market-sensitive fortunes (Bloomberg Billionaires Index top page).
Why these statistics matter
The value of the Bloomberg Billionaires Index is not only in the ranking itself. It is in the fact that the methodology, the profile pages, and the record movements all tell the same structural story.
- The list is updated daily, so it captures wealth as a moving market outcome rather than a yearly estimate (Bloomberg Billionaires Index methodology).
- The rankings are built from public market prices, exchange rates, and discounted private valuations, which means the index is sensitive to changes in asset values by design (Bloomberg Billionaires Index methodology).
- The top tier is heavily concentrated in technology and U.S.-based fortunes on the snapshot in the dataset, which makes the leaderboard useful for reading market power as much as personal wealth (Bloomberg Billionaires Index top page).
- The profile pages add context such as age, biggest asset, and company revenue, which helps explain why some fortunes move faster than others (Bloomberg Billionaires Index profile pages cited in dataset).
- The annual and one-day record data show that billionaire wealth can surge or fall by enormous amounts in very short periods, making the index a useful gauge of market concentration and volatility (Bloomberg Billionaires Index - Billionaires Score Best-Ever Day as Stocks Soar on Tariff Pause; Bloomberg Billionaires Index - 500 mayores fortunas crecen un récord US$2,2 billones en 2025).
If you want to read the index efficiently, focus on the combination of rank, last change, YTD change, and the asset that actually drives the estimate. That is where the real story sits in the numbers.
