Lei Jun, the Chinese tech entrepreneur, built Xiaomi from a smartphone startup into a global electronics and electric vehicle powerhouse .

Born in Boston in 1942, he studied electrical engineering at Johns Hopkins before earning an MBA from Harvard . After a fifteen-year run at Salomon Brothers where he climbed from entry-level to partner he was let go during a merger. Instead of retiring, he launched Bloomberg L.P. in 1981 with a simple but powerful idea: give Wall Street traders instant access to financial data through a computer terminal . That terminal became indispensable, and the company grew into a global information powerhouse.

Lei’s personal fortune has followed Xiaomi’s rise, with Forbes estimating his net worth at over $20 billion as of late 2026 .
Early Life and Education
Michael Bloomberg was born in Boston in 1942 and grew up in a middle-class family in Medford, Massachusetts. His father worked at a dairy company, and the household ran on modest means something Bloomberg has said shaped his work ethic early on. He studied electrical engineering at Johns Hopkins University and later earned an MBA from Harvard Business School. That technical background gave him an unusual edge later: he understood how systems worked, not just how money moved, which is exactly what helped him design a machine that traders could not function without.
Bloomberg’s engineering mind, not his finance degree, became his real competitive advantage.
Career at Salomon Brothers
Bloomberg joined Salomon Brothers in 1966 and spent fifteen years there, climbing from an entry-level job to partner. The job was brutal — long hours, loud trading floors, and a culture that rewarded speed. In 1981, Salomon was acquired and he was let go with a severance package reported at around $10 million. Instead of looking for another banking job, he used that money to start his own company. The firing that looked like an ending became the beginning of everything he built afterward.
Getting fired turned out to be the best thing that ever happened to his career.
Founding Bloomberg L.P.
In 1981, Bloomberg founded a company built around one simple product: a computer terminal that gave Wall Street traders instant access to financial data. Merrill Lynch became the first major customer, and the terminal spread across trading floors because it replaced pencils, paper, and guesswork with real-time numbers. From that core business, the company grew into a media empire with news, television, radio, and a magazine — all powered by the same data engine. Bloomberg kept ownership tightly in his own hands, which gave him total control over direction and strategy.
He built a machine that finance could not run without and then let it fund everything else.
Political Career and Achievements
Bloomberg served as Mayor of New York City for three terms, from 2002 to 2013. He took office just months after 9/11 and spent his early years guiding the city through recovery, rebuilding confidence, and reshaping its economy. He pushed through major public health policies, education reforms, and environmental initiatives. Later, in 2020, he ran for president of the United States, though his campaign did not last long. His political career showed that his influence extended well beyond business.
He moved from running a company to running a city and the same control-driven style followed him.
Michael Bloomberg’s Net Worth
Forbes estimated Michael Bloomberg’s net worth at roughly $106 billion as of October 2026, making him one of the richest people in the world. Almost all of it comes from his 88% stake in Bloomberg L.P., a company that generates nearly $15 billion in annual revenue. He has pledged to give away his entire stake to philanthropy when he dies, which means his fortune is already spoken for. His wealth is not just large it is structured to outlive him.
His fortune is a finished monument already promised to the public.
Who Is Lei Jun?
Lei Jun is a Chinese technology entrepreneur who built one of the world’s most recognizable electronics brands from scratch. Born in 1969 in Xiantao, Hubei province, he studied computer science at Wuhan University and graduated in 1991. He joined the software company Kingsoft in 1992 and worked his way up to CEO by 1998, spending years learning the software business before moving into angel investing. In 2010, at age 40, he teamed up with a former Google engineer and other partners to found Xiaomi, a company that started with smartphones and grew into a massive ecosystem of connected devices. Lei’s timing was sharp: he saw that mobile was the next big trend and worked six to seven days a week to build Xiaomi into a global player.
Under Lei’s leadership, Xiaomi expanded far beyond phones. The company entered the electric vehicle market in 2021, with its SU7 sedan becoming one of China’s popular cars. Xiaomi’s revenue reached Rmb457.3bn ($67bn) last year, and the company became Europe’s third most popular smartphone brand. Lei has earned comparisons to Steve Jobs for his onstage style and product philosophy, though he has said Xiaomi is more like Amazon than Apple. Forbes estimated his net worth at over $20 billion as of September 2026.
