CEO, Bloomberg

$106.2B

Michael Bloomberg, born on February 14, 1942, in Medford, Massachusetts, United States, is an American businessman and politician renowned for founding the financial data-services firm Bloomberg LP and serving as the Mayor of New York City from 2002 to 2013.

In 1981, Bloomberg co-founded Bloomberg LP, a financial information and media company, providing seed funding and currently owning 88% of the business, with estimated revenues exceeding $13 billion. Noteworthy appointments include naming Vlad Kliatchko as CEO of Bloomberg LP and former Bank of England governor Mark Carney as non-executive chair of a new board of directors in August 2023.

Beginning his career on Wall Street in 1966 at investment bank Salomon Brothers, Bloomberg's philanthropic endeavors have seen him donate over $17.4 billion in his lifetime, focusing on causes such as gun safety, climate change, and education. Committed to furthering philanthropy, he pledged to donate his stake in Bloomberg LP to Bloomberg Philanthropies upon his demise, or earlier.

Bloomberg's political career saw him serve as New York City's mayor for 12 years and launch an unsuccessful presidential bid in the 2020 race. He largely self-funded his mayoral campaign, injecting over $68 million from his personal fortune, which was estimated at around $4.5 billion at the time.
