Michael Bloomberg’s net worth is estimated at $94.9 billion as of October 2026, according to Forbes, which ranked him 16th on its 2026 Forbes 400 list of the richest Americans. Almost all of that fortune comes from one company: Bloomberg LP, the financial data and media business he cofounded in 1981 and still owns about 88% of.
Estimates for Bloomberg differ more than you might expect for someone so well known, because Bloomberg LP has never been listed on a stock exchange. With no share price to track, every figure is a valuation call. Forbes had him at $109 billion in March 2026 before trimming that to $94.9 billion in September. The Radar Readout below lines up the published figures and shows how we arrived at ours.

Well reported. Forbes tracks his fortune, but Bloomberg LP is private, so its value is an estimate rather than a stock price.

How Michael Bloomberg’s $94.9 Billion Net Worth Is Built
Forbes does not publish a dollar breakdown of Bloomberg’s fortune, and because Bloomberg LP is private there is no market price to check it against. What Forbes does say is that he owns 88% of the company, which brings in nearly $15 billion a year. That stake is the overwhelming bulk of the total. The rest is personal property and cash.
| Asset | What is known | Source |
|---|---|---|
| Bloomberg LP (about 88%) | The core of the fortune; the company had nearly $15 billion in yearly revenue and about 26,000 employees | Forbes, Wikipedia |
| Manhattan townhouse, 17 East 79th Street | Bought in 1986 for $3.5 million | Celebrity Net Worth |
| Ballyshear estate, Southampton | Bought in 2011 for $20 million | Celebrity Net Worth |
| Chelsea, London mansion | Bought in 2015 for $25 million | Celebrity Net Worth |
| Other property, cash and investments | Mayoral era disclosures listed at least 13 personal properties | Celebrity Net Worth |
| Total | $94.9 billion | Forbes, September 2026 |
The purchase prices above are what he paid years ago, not what the homes are worth today, and they are tiny next to the value of his company stake.
From Salomon Brothers to a $10 Million Head Start
Bloomberg grew up in Medford, Massachusetts. His father was a bookkeeper for a dairy company who never earned more than $6,000 a year. After Johns Hopkins and Harvard Business School, Bloomberg joined the Wall Street investment bank Salomon Brothers in 1966 on a salary of $9,000 a year.
He moved up quickly. He became a general partner in 1972 and went on to run equity trading and later the firm’s computer systems. In 1981 Phibro Corporation bought Salomon, and the new management let him go after 15 years at the firm. He left with $10 million for his equity in the partnership, and that payout became the seed money for everything that followed.
Building Bloomberg LP and the Terminal
Bloomberg had designed in-house computer systems at Salomon, and he bet that traders would pay well for fast, detailed market data on their desks. He started a company called Innovative Market Systems, and in December 1982 it released its first terminal, the Market Master. Merrill Lynch was the first customer, buying 20 terminals and a 30% stake in the company for $30 million.
The business took the name Bloomberg LP in 1986. Over the following years it added Bloomberg News, cofounded with Matthew Winkler in 1990, along with radio, television and messaging and trading tools. In 2009 it bought the magazine BusinessWeek from McGraw-Hill. The terminal subscription remains the core product; Wikipedia puts the company at more than 325,000 terminal subscribers as of 2019.
Growth shows up clearly in what the company was worth when Bloomberg bought back Merrill Lynch’s shares:
- In late 1996 he bought one third of Merrill’s 30% stake for $200 million, a deal that valued the company at $2 billion.
- In 2008, during the financial crisis, Merrill sold its remaining 20% back for a reported $4.43 billion, valuing the company at roughly $22.5 billion.
That second deal lifted his ownership to the roughly 88% he holds today. Revenue reached about $10 billion in 2018, according to a leaked internal memo reported by Business Insider, and Forbes now estimates it at nearly $15 billion a year.
Stepping Back From Running the Company
Bloomberg was chief executive from 1981 to 2001, and again from 2014 to 2023. While he served as mayor of New York City from 2002 to 2013, he took a salary of $1 a year in place of the usual mayoral pay. In August 2023 he handed the CEO role to product chief Vlad Kliatchko, and Forbes notes that former Bank of England governor Mark Carney became non-executive chair of a new board of directors.
Celebrity Net Worth reports that he spent $268 million of his own money across three mayoral elections and about $1.05 billion on his 2020 presidential run. Those are large sums, but they are small against a fortune that kept climbing through the same period.
How His Fortune Has Grown
Forbes has tracked Bloomberg for years. Its annual billionaires list shows how steadily his wealth rose with the company’s revenue:
| Forbes list | Net worth |
|---|---|
| March 2009 | $16 billion |
| March 2017 | $47.5 billion |
| March 2019 | $55.5 billion |
| April 2020 | $48 billion |
| April 2022 | $82 billion |
| April 2024 | $106 billion |
| April 2025 | $105 billion |
| March 2026 | $109 billion |
| September 2026 (Forbes 400) | $94.9 billion |
The September 2026 figure is his first sizable step down on a Forbes list since 2020. Forbes has not set out the reason on his profile, so we report the number without guessing at the cause. Because his wealth is tied to a private company, it tends to move in larger jumps when Forbes revalues the business rather than day to day like a stock.
Bloomberg Philanthropies and the Giving Pledge
Bloomberg is one of the biggest donors in the world. Forbes says he gave away $4.3 billion in 2025 and more than $25.4 billion over his lifetime, to causes including gun safety, climate change and education. The Chronicle of Philanthropy named him the biggest American donor of 2025, the third year in a row he topped its Philanthropy 50 list. Celebrity Net Worth puts his 2024 giving at $3.7 billion.
He signed the Giving Pledge in August 2010, promising to give away at least half of his wealth. Forbes adds that he has committed to leave his Bloomberg LP stake to Bloomberg Philanthropies when he dies, if not sooner. That means the company at the heart of his fortune is ultimately set to fund his foundation.
Some of his largest single gifts have gone to Johns Hopkins University, his alma mater:
- $1.8 billion in 2018 for student financial aid, making admissions need blind.
- $1 billion in 2024 to make medical school tuition free for students whose families earn under $300,000 a year, on top of the more than $3.5 billion Forbes says he had already given the school.
Through Bloomberg Philanthropies he has also reached $1 billion in commitments to reduce tobacco use, mainly in low and middle income countries, and in 2022 joined eight other foundations in a $1 billion commitment to ocean conservation. The foundation’s main areas are public health, the arts, government innovation, the environment and education.
Why Other Sites Say $95 Billion or $109 Billion
| Source | Figure | Date | Why it differs |
|---|---|---|---|
| Forbes Billionaires list | $109 billion | March 2026 | Older valuation, before the Forbes 400 revision |
| Forbes 400 | $94.9 billion | September 2026 | Latest Forbes valuation, still shown in October 2026 |
| Celebrity Net Worth | $95 billion | October 2026 | Rounds the latest Forbes figure |
| Net Worth Radar | $94.9 billion | October 2026 | Uses the latest Forbes figure |
Older articles quoting $105 billion to $109 billion are not wrong for their date; they simply predate the September 2026 Forbes revision. We could not read the Bloomberg Billionaires Index profile for this update, so it is not included in the comparison.
