Starting from Scratch
Michael Bloomberg was born in a middle-class Boston neighbourhood in 1942. His dad was a bookkeeper at a dairy company. Bloomberg was ambitious and smart. He studied electrical engineering at Johns Hopkins University, then got his MBA from Harvard Business School.
In 1966, he got a job at Salomon Brothers, one of Wall Street’s biggest investment banks. He started at the very bottom, literally counting sock certificates in the back office. But Bloomberg had hustle. He worked his way up over 15 years, eventually becoming a partner at the firm. Life was good. He was making serious money and had a bright future ahead.
But in 1981, Salmon Brothers got acquired, and Bloomberg was out. The company gave him a $10 million as a severance package. He was 39 years old and suddenly unemployed.

The Big Idea that Changed Everything
Bloomberg started thinking instead of feeling sorry for himself. During the period he worked on Wall Street, he had noticed something frustrating: getting accurate, real-time financial information was incredibly difficult. Traders would scramble around trying to piece together data from different sources, often getting outdated or incomplete information.
Bloomberg thought that if there was one system that gave you everything you needed, like stock prices, news, analytics, and historical data, all in one place and updated in real time. So, in 1981, along with that $10 million severance, he started a company called Innovative Market Systems. His product was the Bloomberg Terminal, a specialized computer system designed specifically for financial professionals. It wasn’t cheap; terminals cost around $20,000 a year to lease, but for Wall Street traders, it was worth every penny.
Within the first year, Merril Lynch ordered $30 million worth of terminals and invested in Bloomberg’s company. With other firms quickly following, the Bloomberg Terminal became essential equipment in every trading floor around the globe.

Building a fortune
Now, Bloomberg L.P pulls in about $10 billion in revenue every year. The company has hundreds of thousands of terminals installed in financial institutions across the world. The interesting fact is that Bloomberg still owns 88% of the company. That massive ownership makes him incredibly wealthy.
If Bloomberg L.P. were a publicly traded company, experts estimate it would be worth somewhere between $60 billion and $70 billion.
His wealth has grown steadily over the years. By 2008, his wealth doubled to $8 billion from $4 billion in 2000. By 2017, it crossed $47.5 billion. Today, Michael Bloomberg’s net worth is sitting around $105 billion. Quite impressive for a person who got fired 43 years ago.
Beyond that, Bloomberg has invested smartly in real estate. He owns stunning properties in New York, Bermuda, London, Vail, and Florida. They are really multi-million-dollar assets that have appreciated significantly over time.

The mayor who worked for a dollar
Bloomberg decided to try something completely different in 2001. He entered politics and ran for mayor of New York City and won. Bloomberg declined his mayoral salary because he was so wealthy. The job paid $195,000 a year, but he took only $1. He ran America’s largest city for 12 years basically free.
His three terms as mayor were transformative for New York. He implemented sweeping public health initiatives, including the controversial smoking ban in restaurants and bars. He pushed environmental policies, improved schools, and helped the city recover from the 2008 financial crisis. People have mixed feelings about his tenure, but nobody can say he didn’t put in the work.
In 2020, Bloomberg ran for president. Things got wild at that time, and he spent a staggering $935 million of his own money on his campaign. It was denoted as the most expensive primary campaign in American history.
But the campaign didn’t go as well as he planned. He won only 61 delegates before dropping out. Critics called it a massive waste of money. Bloomberg saw it as investing in issues he cared about, particularly climate change and gun control.

Giving it all away
In 2010, Bloomberg joined the Giving Pledge, promising to give away at least half of his wealth to charity. He has given away $17.4 billion as of 2023, making him America’s biggest philanthropist that year. The number is more than the entire net worth of most billionaires.
Bloomberg had donated over $4.55 billion to Johns Hopkins University. In 2024, he announced a jaw-dropping $1 billion gift to make Johns Hopkins medical school completely free for students whose families earn less than $300,000 a year.
He tackled many big global problems through his philanthropies, like climate change, public health, and culture. With his effort, he shut down coal plants and promoted clean energy. His public health initiatives include improving nutrition and supporting global health programs.
