Michael Bloomberg

Michael Rubens Bloomberg (born February 14, 1942) is an American businessman, politician, and philanthropist who founded Bloomberg L.P. in 1981, a financial information and media company that revolutionized trading with the Bloomberg Terminal. He served as the 108th mayor of New York City for three consecutive terms from 2002 to 2013, during which he focused on economic recovery post-9/11, crime reduction, and public health initiatives.

Bloomberg's mayoral administration implemented data-driven policies, including aggressive policing strategies like expanded stop-and-frisk practices that correlated with significant drops in violent crime rates, though these were later criticized for racial disparities in enforcement and led to federal court rulings deeming them unconstitutional. Other notable efforts included a ban on large sugary drinks to combat obesity, which faced legal challenges but highlighted his emphasis on behavioral interventions for health outcomes. His leadership emphasized fiscal discipline and infrastructure improvements, contributing to New York City's rebound as a global financial hub.

As of October 2025, Bloomberg's net worth stands at approximately $109.4 billion, primarily from his ownership stake in Bloomberg L.P., making him one of the world's richest individuals. Through Bloomberg Philanthropies, he has given $21.1 billion to initiatives in public health, environmental sustainability, arts, and government reform, including anti-smoking campaigns and climate action efforts that have influenced policy worldwide. Bloomberg briefly entered the 2020 Democratic presidential primaries, spending over $1 billion of his own funds before withdrawing and endorsing Joe Biden, reflecting his pragmatic approach to politics often independent of strict partisan lines.
