Lei Jun is the founder, chairman and chief executive of Xiaomi, the Hong Kong listed technology company that began with smartphones and has since pushed into electric vehicles and a wide range of connected home devices. Forbes describes his source of wealth as smartphones and automobiles, and lists him among the world’s richest people. The precise size of his fortune, however, moves with Xiaomi’s share price, which makes any single figure a snapshot rather than a settled fact.
Who is Lei Jun?
Lei was born in December 1969 in Xiantao, Hubei province, and enrolled at Wuhan University in 1987 to study computer science, according to Xiaomi’s own corporate profile. He graduated in 1991. Reports have long noted that he completed his undergraduate credits in about two years, and university accounts describe him receiving a 2,000 yuan scholarship as a student, a detail he has publicly linked to a later pledge to give back to the school.
His early career ran through software rather than hardware. He joined Kingsoft in 1992, rose to chief executive in 1998, and later returned to the company as chairman in 2011. He also founded the online retailer Joyo.com, which Amazon acquired in 2004. Forbes records that sale at $75 million. Those years gave Lei a reputation as an operator who understood both software products and consumer internet distribution before he ever made a phone.
How Xiaomi became the core of the fortune
Lei founded Xiaomi in April 2010 at age 40. The company’s first years were built on value focused smartphones sold largely online, a model that helped it climb quickly in China and then abroad. Xiaomi listed in Hong Kong in 2018, and its shares became the main engine of Lei’s personal wealth. Because Forbes and other trackers value his holdings largely by reference to that listed stock, his ranking rises and falls with investor sentiment toward Xiaomi rather than with any fixed asset.
Xiaomi has spent recent years trying to move upmarket in phones and to establish itself in electric cars. Lei announced the automotive ambition in 2021 and described it as his last major startup project. The company launched its first electric sedan, the SU7, in 2024, and later added the YU7 SUV. News reports have described Lei’s hands on approach to vehicle development, including buying Tesla Model Ys for teardown study, though the commercial results of those efforts belong to Xiaomi as a company and not to his personal ledger.
What underpins the wealth beyond Xiaomi
Lei’s holdings are not confined to a single company. Forbes identifies him as chairman of the Hong Kong listed software firm Kingsoft and an investor in JOYY, the Nasdaq listed live streaming and social platform formerly known as YY.com. He has also been an active angel investor and co founded Shunwei Capital with Xu Dalai in 2011, a venture firm that has backed a long list of Chinese startups. These positions matter to any honest account of his finances because a stake in a listed company can be valued, while private investments usually cannot be priced with confidence.
One widely reported transaction illustrates how much of Lei’s history sits outside Xiaomi: the Joyo.com sale to Amazon for $75 million in 2004. That deal is documented by Forbes and is not an estimate. It also helps explain why Lei is often described as a serial builder rather than a one company founder.
Philanthropy and the scholarship story
Lei’s giving has become part of his public identity. Wuhan University has said he first donated to the school in 1997, only a few years after graduating, and his donations over the following decades included a scholarship fund, a science and technology building and support for the university’s Covid-19 response. In November 2023 he donated 1.3 billion yuan in cash, which Forbes reported as roughly $182 million at the time and which the university described as its largest single individual donation.
That gift is often framed as the repayment of the 2,000 yuan scholarship. Lei himself has spoken about the promise he made as a student to return the help many times over. The donation is a documented event. The emotional narrative around it is his own account, which is worth separating from the financial record.
Reading the numbers: why estimates vary
Any current net worth figure for Lei is a valuation exercise, not an audited statement. Forbes publishes a real time figure that reflects the prior trading day’s movement in the companies he holds, and it changes constantly. Other trackers use different dates, different share price snapshots and different assumptions about debt, private stakes and family holdings. The result is a spread of figures that can look contradictory but may simply be measured at different moments.
Readers should treat all of these numbers as journalist estimates of fluctuating market value. They are useful for context and ranking, and they are not personal bank statements. Where sources disagree, the disagreement is part of the story.
Summary Table of Estimates
The following table records estimates as published by the named sources on the dates shown. Amounts are reproduced as reported and are not averaged or reconciled. Each figure is an unverified estimate of fluctuating market value, not a confirmed personal fortune.
| Source | Published estimate | Date | Caveat |
|---|---|---|---|
| Forbes | $21.5B | Real time net worth as of 10/18/26 | Real time figure based on prior trading day; varies with share prices |
| Forbes | $21.8B | Real time net worth as of 9/14/26 | Real time figure based on prior trading day; varies with share prices |
| Times of India, citing Forbes | over $20 billion | September 2026 | Article summary of a Forbes estimate; exact methodology not given |
| DNA India, citing Forbes | USD 35.1 billion | November 2025 | Figure reported in a news article; timing and methodology differ from the Forbes real time entries above |
The wide gap between the figures above shows why a single number cannot be treated as definitive. The lower figures are recent Forbes real time snapshots, while the higher figure was published at an earlier date in a secondary news report. None of them should be read as a verified statement of Lei’s personal wealth.
How to think about Lei Jun’s net worth
A clearer way to frame the question is to ask what is documented and what is estimated. It is documented that Lei founded Xiaomi, that the company listed in Hong Kong, that he chairs Kingsoft, that he invested in JOYY, that Joyo.com sold to Amazon and that he made a 1.3 billion yuan donation to Wuhan University. It is estimated that his total fortune sits somewhere in the tens of billions of dollars, with the exact number depending on the day and the source.
That distinction matters most when figures appear in headlines. A real time listing can move by hundreds of millions of dollars in a single trading session, and a secondary report may reuse an older number without saying so. For a founder whose main asset is a listed stock, volatility is not an exception. It is the normal condition of the balance sheet.
