Michael Rubens Bloomberg (born February 14, 1942) is an American businessman, politician, and philanthropist who co-founded Bloomberg L.P., the global financial information and media company, and served three consecutive terms as the 109th Mayor of New York City from 2002 to 2013. Born in Boston and raised in Medford, Massachusetts, Bloomberg built his career from a position at the securities brokerage firm Salomon Brothers into one of the most consequential business empires in the financial information industry. His company's flagship product, the Bloomberg Terminal, became a ubiquitous tool on Wall Street and in financial institutions worldwide. Bloomberg's transition from the private sector to public office made him one of the few self-made billionaires to govern a major American city, and his tenure as mayor reshaped New York's physical landscape, public health policies, and education system in the aftermath of the September 11 attacks. A lifelong Democrat who switched to the Republican Party to run for mayor in 2001 and later became an Independent in 2007 before rejoining the Democrats in 2018, Bloomberg has defied conventional partisan classification throughout his public life. As of December 2025, Bloomberg has a net worth of approximately $109.4 billion, making him the 17th richest person in the world. He has given away $17.4 billion to philanthropic causes over the course of his lifetime and is a signatory of the Giving Pledge.

Early Life

Michael Rubens Bloomberg was born on February 14, 1942, in Boston, Massachusetts. He grew up in Medford, Massachusetts, a middle-class suburb north of Boston. Bloomberg's upbringing in Medford shaped his early outlook and work ethic. Details of his family background indicate a modest household; when Bloomberg launched his career after college in the 1960s, he earned $11,500 a year at his first job — a sum that, while more substantial in that era, reflected the entry-level nature of his initial position in the financial industry.

Bloomberg's early years in Medford established the foundation for what would become a career spanning finance, technology, media, politics, and philanthropy. He attended local schools in the Medford area before pursuing higher education at two of the most prominent institutions in the eastern United States.

Education

Bloomberg earned a Bachelor of Science in Engineering (BSE) from Johns Hopkins University in Baltimore, Maryland. He subsequently attended Harvard Business School in Boston, Massachusetts, where he received a Master of Business Administration (MBA). His education at Johns Hopkins provided a technical and analytical foundation, while his MBA from Harvard equipped him with the business acumen that would prove instrumental in his later entrepreneurial ventures. Bloomberg has maintained connections with both institutions throughout his career, and his educational background in engineering and business informed the data-driven, technocratic approach he would later bring to both corporate management and public governance.

Career

Salomon Brothers

After completing his MBA at Harvard Business School, Bloomberg began his career at Salomon Brothers, a prominent Wall Street securities brokerage firm. He worked at the firm during a formative period in the American financial industry. Bloomberg's time at Salomon Brothers gave him deep insight into the information needs of traders, analysts, and financial professionals — an understanding that would directly inform his next venture. He spent approximately fifteen years at the firm before departing to launch his own enterprise.

Bloomberg L.P.

In 1981, Bloomberg founded his own company, which would become Bloomberg L.P., a financial information, software, and media firm. The company's cornerstone product, the Bloomberg Terminal, revolutionized the way financial professionals accessed and analyzed market data, news, and analytics. The terminal became an essential tool in trading floors, investment banks, and financial institutions globally, creating a near-indispensable platform for the industry.

Bloomberg served as chairman and chief executive officer (CEO) of Bloomberg L.P. for approximately twenty years, from 1981 to 2001, building it into a major financial data and media empire. The company expanded beyond its terminal business to include Bloomberg News, Bloomberg Television, Bloomberg Radio, and other media properties, establishing itself as a significant force in financial journalism and information services.

Bloomberg stepped down as CEO in 2001 to pursue his first mayoral campaign. After completing his three terms as mayor and a period focused on philanthropy, he returned to lead the company, re-assuming the position of CEO at Bloomberg L.P. by the end of 2014. He served in that role until 2023. Bloomberg remains the majority owner of Bloomberg L.P.

Mayor of New York City

2001 Election

Bloomberg was elected the 109th mayor of New York City in November 2001, succeeding Rudy Giuliani. A lifelong Democrat, Bloomberg switched to the Republican Party to run for mayor, a strategic decision that allowed him to avoid a crowded Democratic primary in the heavily Democratic city. The election took place in the immediate aftermath of the September 11 attacks, which had devastated lower Manhattan and fundamentally altered the city's political and economic landscape. Bloomberg took office on January 1, 2002.

First Term (2002–2005)

Bloomberg's first term as mayor was defined in large part by the city's recovery from the September 11 attacks. He led a comprehensive re-zoning of large areas of New York City, which facilitated massive and widespread new commercial and residential construction in the years following the attacks. This re-zoning effort reshaped the city's physical landscape and set the stage for a building boom that would continue for years.

Bloomberg pursued a governing style described as technocratic and managerial, applying the data-driven approach he had honed in the private sector to the challenges of municipal governance. He pursued socially liberal and fiscally moderate policies, a combination that often defied easy partisan categorization.

During this period, Bloomberg's first deputy mayor was Marc Shaw, who served from 2002 to 2005.

2005 Re-election

Bloomberg won re-election in 2005, securing a second term as mayor. His re-election campaign benefited from his record of post-9/11 recovery efforts and his investments in education and infrastructure. Patricia Harris succeeded Marc Shaw as first deputy mayor and served in that role from 2006 to 2013.

Second Term (2006–2009)

Bloomberg's second term saw the continuation and expansion of his signature policy initiatives. He established public charter schools as part of a broader effort to reform the city's education system. He pursued public health initiatives, including restrictions on smoking in public places and efforts to combat obesity. Bloomberg also became a prominent national voice on gun control, founding and funding organizations dedicated to reducing gun violence.

Bloomberg rebuilt urban infrastructure across the city and supported environmental protections, positioning New York as a leader among American cities on climate and sustainability issues.

In 2007, Bloomberg left the Republican Party and registered as an Independent, further underscoring his non-partisan governing approach. This move fueled speculation about a potential independent presidential bid, though Bloomberg ultimately chose not to run in 2008.

Third Term and Term Limits Controversy

New York City's term limits law, which had been championed by Ronald Lauder and enacted through public referendum, originally restricted the mayor and other city officials to two consecutive four-year terms. In 2008, Bloomberg sought to extend the term limit to three terms, a controversial effort that required action by the New York City Council rather than a public vote. The push for a third term generated significant public debate and criticism.

Bloomberg won his third term in the November 2009 election, though by a narrower margin than many observers had anticipated. The closer-than-expected result reflected public ambivalence about the term limits change and the substantial personal spending Bloomberg directed toward his campaign. Bloomberg's expenditure on his Independence Party line also attracted attention.

Third Term (2010–2013)

Bloomberg's third and final term continued his emphasis on urban development, public health, and education reform. He remained the most recent mayor of New York City to serve as either a Republican or an Independent. Bloomberg left office on December 31, 2013, and was succeeded by Bill de Blasio.

Stop-and-Frisk Controversy

One of the most contentious aspects of Bloomberg's tenure as mayor was the city's stop-and-frisk policing program, which expanded significantly during his administration. The program disproportionately affected Black and Latino New Yorkers and drew sustained criticism from civil rights organizations, community groups, and legal advocates. A federal judge ruled in 2013 that the New York City Police Department had violated the constitutional rights of minorities through its stop-and-frisk practices. Bloomberg initially defended the program as a crime-reduction tool but reversed his position before his 2020 presidential campaign, issuing a public apology for the policy.

2020 Presidential Campaign

In November 2019, approximately four months before Super Tuesday, Bloomberg officially launched his campaign for the Democratic nomination for president of the United States in the 2020 election. Bloomberg had rejoined the Democratic Party in 2018 in preparation for the run. His late entry into the race was unusual; he skipped the early primary and caucus states, instead focusing his resources on the Super Tuesday contests.

Bloomberg self-funded his campaign to an extraordinary degree, spending $935 million on his candidacy. This set the record for the most expensive presidential primary campaign in American history and represented the highest spending in any political capacity by a single individual in U.S. history. Despite this massive financial investment, the campaign failed to gain sufficient traction with Democratic primary voters. Bloomberg ended his campaign in March 2020 after winning only 61 delegates, and he subsequently endorsed Joe Biden.

Continued Political Engagement

Following his 2020 presidential campaign, Bloomberg has remained active in American politics through financial contributions and advocacy. In October 2025, Bloomberg invested substantially in Colorado political campaigns, writing a $500,000 check that reshaped the early race for Colorado governor and earning attention as a potential "kingmaker" in the state's politics.

Also in October 2025, Bloomberg donated $1.5 million to a pro-Andrew Cuomo super PAC, re-entering the New York political landscape after having previously backed Cuomo's failed bid.

Bloomberg has also remained a top funder of the American gun-control movement, continuing to direct significant resources toward organizations and campaigns focused on reducing gun violence.

Personal Life

Bloomberg has been in a relationship with Diana Taylor since 2000. He has two children, including his daughter Georgina Bloomberg, who is known for her career in equestrian sports.

Bloomberg is a signatory of the Giving Pledge, the commitment initiated by Warren Buffett and Bill Gates encouraging the world's wealthiest individuals to dedicate the majority of their wealth to philanthropy. Over the course of his lifetime, Bloomberg has given away $17.4 billion to philanthropic causes, making him one of the largest individual philanthropic donors in history. His philanthropic activities have focused on areas including public health, the environment, education, and government innovation.

After leaving the mayor's office at the end of 2013, Bloomberg spent a period focused full-time on his philanthropic endeavors before returning to Bloomberg L.P. as CEO by the end of 2014.

A 2026 article in The New Yorker compared Bloomberg to New York City Council member Zohran Mamdani, noting that despite their vastly different political orientations — one a plutocrat and the other a socialist — both figures "embody outsized ideas of the city" and represent distinct visions of New York.

Recognition

In 2024, Bloomberg received the Presidential Medal of Freedom from President Joe Biden, the nation's highest civilian honor. The award recognized Bloomberg's contributions across business, public service, and philanthropy.

Bloomberg's influence on New York City during his three terms as mayor has been the subject of extensive analysis and commentary. His administration's rezoning efforts, public health campaigns, education reforms, and infrastructure investments reshaped the city in ways that remained visible long after he left office. His approach to governance — characterized by data-driven decision-making and a willingness to use executive authority to advance policy goals — influenced a generation of municipal leaders.

In the business world, Bloomberg's creation of the Bloomberg Terminal and the broader Bloomberg L.P. enterprise fundamentally changed the financial information industry. The terminal became a standard tool in the global financial sector, and the company's expansion into news media created one of the world's largest financial news organizations.

Bloomberg's philanthropic record, totaling $17.4 billion in lifetime giving, has placed him among the most significant individual donors in modern history. His giving has supported initiatives in public health — including global anti-smoking campaigns and efforts to combat climate change — as well as education and arts organizations.

Legacy

Bloomberg's career has spanned the worlds of finance, technology, media, politics, and philanthropy in a manner achieved by few individuals in American public life. His founding of Bloomberg L.P. created a company that transformed how financial information is distributed and consumed, while his twelve years as mayor of New York City left a lasting imprint on the nation's largest city.

His political career was notable for its ideological fluidity. Having been a Democrat, Republican, and Independent at various points, Bloomberg pursued a governing philosophy that prioritized pragmatic, data-driven solutions over partisan orthodoxy. His socially liberal and fiscally moderate policies drew support and criticism from across the political spectrum.

Bloomberg's record on stop-and-frisk remains one of the most debated aspects of his legacy, with defenders crediting the policy for contributing to reductions in crime and critics condemning its disproportionate impact on communities of color. His public reversal on the issue before his 2020 presidential campaign acknowledged the harm caused by the policy but did not resolve the broader debate about policing and civil liberties in New York City.

His 2020 presidential campaign, while unsuccessful, set records for individual spending on a political campaign and raised questions about the role of personal wealth in American democratic processes. The $935 million Bloomberg spent on his primary bid far exceeded the spending of any other candidate in the race.

As of December 2025, Bloomberg continues to exert influence in American politics and philanthropy, directing resources toward gun control advocacy, environmental causes, and political campaigns across the country. His net worth of approximately $109.4 billion makes him one of the wealthiest individuals in the world, and his continued engagement in public affairs ensures that his influence on American politics and policy remains a subject of ongoing analysis and debate.
