Who Is Lei Jun?
Lei Jun is the founder, chairman, and CEO of Xiaomi, one of the world’s best-known smartphone brands. Before Xiaomi, he spent years at Kingsoft and made early bets on companies like YY. People often call him “China’s Steve Jobs,” though he describes himself as an engineer first.
Is There a Connection Between Michael Bloomberg and Lei Jun?
I found no public record of a partnership, joint venture, or personal relationship between the two men. The links are indirect:
- Both studied technical subjects: electrical engineering for Bloomberg, computer science for Lei.
- Both built fortunes through technology, not inheritance.
- Both gave large sums to their universities.
- The Bloomberg Billionaires Index tracks Lei Jun’s wealth.
So the connection is a comparison, not a collaboration.
How Michael Bloomberg Built His Business
Bloomberg started at Salomon Brothers in 1966 on a $9,000 salary. He became a general partner in 1972 and ran equity trading. In 1981, Salomon was acquired, and he lost his job after 15 years.
He took his roughly $10 million partnership payout and started Innovative Market Systems with three former colleagues. The idea was simple: put real-time prices, analytics, and news into a single computer terminal.
Key moments in the company’s growth:
- 1982: Merrill Lynch became the first big customer and invested $30 million for a 30% stake.
- 1986: The company was renamed Bloomberg LP.
- 1990: Bloomberg News launched, followed by radio, TV, and Businessweek.
- 2008: Merrill Lynch sold its remaining 20% back for $4.425 billion, valuing the company above $22 billion.
Today the firm earns close to $15 billion a year and employs about 26,000 people. Bloomberg owns an estimated 88%. Because the company is private, his net worth rests on valuation estimates, not a daily stock price.
He also served as New York’s mayor from 2002 to 2013 for a salary of $1 a year.
How Lei Jun Built Xiaomi
Lei grew up in Hubei with teacher parents and loved taking radios apart. He joined Kingsoft in 1992 and became CEO in 1998. He also founded the online retailer Joyo.com, sold to Amazon in 2004 for $75 million. A $1 million bet on YY in 2005 grew to $129 million at its 2012 IPO.
In 2010 he co-founded Xiaomi with a team of partners, including former Google executive Lin Bin. The pitch was good hardware at a fair price, sold mostly online, with a loyal fan community. The first phone arrived in 2011, and the company turned profitable in 2013.
Xiaomi’s major milestones:
- July 2018: Listed in Hong Kong under stock code 1810, the first company on the exchange with a weighted voting rights structure.
- 2019: Became the youngest company on the Fortune Global 500 at that time.
- March 2021: Announced a $10 billion investment in electric vehicles over ten years.
- 2024: Reported revenue of 366 billion yuan, about $50.8 billion.
Most of Lei’s wealth sits in his Xiaomi shares, held through a holding company. That is why his fortune moves sharply with the stock. Per one tracker, it peaked near $36 billion in October 2025 and has since fallen by roughly 40%.
Their Biggest Business Difference: What Customers Buy
This is the clearest split between the two empires.Bloomberg sells information as a subscription. Professionals pay a high annual fee, often cited above $30,000 per terminal, to get data, analytics, and messaging in one place. Customers rarely leave, because switching means retraining a whole desk. That recurring revenue is the engine behind his fortune.
Lei sells products to the public. Xiaomi makes money on phones, wearables, smart-home gadgets, and now cars, plus internet services layered on top. Hardware margins are thinner and competition is fierce, so Xiaomi has to win on value and volume.
In short, Bloomberg’s customers are institutions buying an edge. Lei’s customers are everyday people buying a good deal.

Who Is Richer, Michael Bloomberg or Lei Jun?
Michael Bloomberg is richer, by roughly four times. Numbers vary by tracker and date, so here are the main snapshots.
| Measure | Michael Bloomberg | Lei Jun |
| Forbes World’s Billionaires, March 2026 | $109 billion (#18) | $27.9 billion (#90) |
| Later 2026 estimate (October) | About $95 billion (Celebrity Net Worth; Forbes state list: $94.9 billion) | $21.6 billion (Forbes, #118) |
| Main source of wealth | Bloomberg LP | Xiaomi shares |
| Company type | Private | Public |
| Wealth gap | About 3.9x (March) | About 4.4x (October) |
Both fortunes fell between March and October 2026, so treat any single figure as a snapshot. Lei’s wealth swings more because it follows a live share price. Bloomberg’s changes more slowly because his company is valued by estimate.
A Shared Commitment to Their Universities
Both men repaid the schools that launched them.Bloomberg gave $1.8 billion to Johns Hopkins in 2018, which let the school move to need-blind admissions. In 2024 he added $1 billion to make medical school tuition-free for students from families earning under $300,000. His total giving has reached about $25.4 billion.
Lei gave 1.3 billion yuan (about $182 million) to Wuhan University in November 2023, the largest individual alumni cash gift a Chinese mainland university had received. He said he wanted to repay the 2,000 yuan scholarship he once received. The money supports basic research, computer science, and student development. In 2021 he also donated over $2.2 billion worth of Xiaomi shares to charity.
The scale differs, but the motive looks alike: education opened the door, and both want to keep it open.
