He is the majority owner and co-founder of [[Bloomberg L.P.]], and was its CEO from 1981 to 2001, and again from 2014 to 2023.<ref>{{cite news |last1=Mullin |first1=Benjamin |title=Bloomberg L.P., a Financial Data Giant, Overhauls Its Leadership Ranks |work=The New York Times |date=August 21, 2023 |url=https://www.nytimes.com/2023/08/21/business/media/bloomberg-lp-succession.html#:~:text=lp%2Dsuccession.html-,Bloomberg%20L.P.%2C%20a%20Financial%20Data%20Giant%2C%20Overhauls%20Its%20Leadership%20Ranks,Paul%20Zammitt%20its%20new%20president. |access-date=October 24, 2023}}</ref> He [[Mayoralty of Michael Bloomberg|served as]] the 108th [[mayor of New York City]] for three terms, from 2002 to 2013, and was a candidate for the [[2020 Democratic presidential primaries|2020 Democratic nomination]] for [[president of the United States]].

Bloomberg grew up in [[Medford, Massachusetts]], and graduated from [[Johns Hopkins University]], in Baltimore, Maryland, and [[Harvard Business School]] in Boston, Massachusetts. He began his career at the securities brokerage firm [[Salomon Brothers]], before forming his own company in 1981. That company, [[Bloomberg L.P.]], is a financial information, software, and media firm that is known for its [[Bloomberg Terminal]]. Bloomberg spent the next twenty years as its chairman and CEO. According to ''[[Forbes]]'', as of May 2025, Bloomberg's estimated net worth stood at US$104.7 billion, making him the 18th richest individual in the world.<ref name=Forbes>{{Cite magazine|title=Michael Bloomberg|url=https://www.forbes.com/real-time-billionaires/ |magazine=Forbes|access-date=February 17, 2025}}</ref> Bloomberg, who has signed [[the Giving Pledge]], has given away $17.4 billion to philanthropic causes in his lifetime.<ref name=":0" /> After a brief stint as a full-time philanthropist, he re-assumed the position of CEO at Bloomberg L.P. by the end of 2014.

Bloomberg was elected the [[List of mayors of New York City|108th]] mayor of New York City in [[2001 New York City mayoral election|2001]]. He held office for three consecutive terms, winning re-election in [[2005 New York City mayoral election|2005]] and [[2009 New York City mayoral election|2009]]. Pursuing [[Political positions of Michael Bloomberg|socially liberal and fiscally moderate policies]], Bloomberg developed a [[Technocracy|technocratic managerial style]].<ref>{{cite news |last1=Cooper |first1=Michael |title=Political Memo; Bloomberg, the Technocrat, Seeks His Inner La Guardia |url=https://www.nytimes.com/2003/10/01/nyregion/political-memo-bloomberg-the-technocrat-seeks-his-inner-la-guardia.html |access-date=2 October 2025 |agency=The New York Times |date=1 October 2003}}</ref>

As the mayor of New York, Bloomberg established public [[charter school]]s, rebuilt urban infrastructure, and supported [[Gun politics in the United States|gun control]], [[public health]] initiatives, and [[Environmental policy of the United States|environmental protections]]. He also led a re-zoning of large areas of the city, which facilitated massive and widespread new commercial and residential construction after the [[September 11 attacks]]. Bloomberg is considered to have had far-reaching influence on [[politics of New York City|the politics]], [[Economy of New York City|business sector]], and [[culture of New York City]] during his three terms as mayor. He has also faced significant criticism for the city's [[stop and frisk]] program, support for which he reversed with an apology before his 2020 presidential run.<ref>{{Cite web|title=Bloomberg apologizes for "stop-and-frisk" police practice|url=https://www.nbcnews.com/news/nbcblk/bloomberg-apologizes-stop-frisk-police-practice-n1084756|access-date=July 24, 2020|website=NBC News|date=November 18, 2019 |language=en}}</ref>

In November 2019, four months before [[Super Tuesday]], Bloomberg officially launched [[Michael Bloomberg 2020 presidential campaign|his campaign]] for the Democratic nomination for president of the United States in the [[2020 United States presidential election|2020 election]]. He ended his campaign in March 2020, after having won only 61 delegates.

After a [[Two-round system|runoff]], the Democratic nomination went to [[New York City Public Advocate]] [[Mark Green (New York politician)|Mark Green]].

Bloomberg received Giuliani's endorsement to succeed him in the 2001 election. He also had a huge campaign spending advantage. Although New York City's [[Campaign finance in the United States|campaign finance]] law restricts the total amount of contributions that a candidate can accept, Bloomberg chose not to use public funds and therefore his campaign was not subject to these restrictions. He spent $73&nbsp;million of his own money on his campaign, outspending Green by a ratio of five to one.<ref>{{cite news |url=http://www.nydailynews.com/news/ideas_opinions/story/143966p-127415c.html |title=Mike's Wrong, Campaign Fixes Make Sense |work=[[Daily News (New York)|Daily News]] |location=New York |author=Russianoff, Gene |date=December 9, 2003 |archive-date=January 5, 2006 |archive-url=https://web.archive.org/web/20060105025803/http://www.nydailynews.com/news/ideas_opinions/story/143966p-127415c.html|author-link=Gene Russianoff }}</ref>

=== Public image and lifestyle ===

Throughout his business career, Bloomberg has made numerous statements which have been considered by some to be insulting, derogatory, sexist or misogynistic. When working on Wall Street in the 1960s and 1970s, Bloomberg claimed in his 1997 autobiography, he had "a girlfriend in every city".<ref>{{cite news |author=Kranish, Michael |date=February 15, 2020 |title=Mike Bloomberg for years has battled women's allegations of profane, sexist comments |url=https://www.washingtonpost.com/graphics/2020/politics/michael-bloomberg-women/ |archive-url=https://web.archive.org/web/20200215231238/https://www.washingtonpost.com/graphics/2020/politics/michael-bloomberg-women/ |archive-date=February 15, 2020 |access-date=February 17, 2020 |newspaper=The Washington Post |department=Politics}}
