About
He served as the 109th mayor of New York City from 2002 to 2013. He was a lifelong Democrat until 2001, when he switched to the Republican Party to run for mayor, and later becoming an independent in 2007. Bloomberg is the most recent mayor of New York City to serve as a Republican or Independent. In 2018, he rejoined the Democratic Party, after which he ran an unsuccessful campaign for the 2020 Democratic nomination for president of the United States. Bloomberg is a centibillionaire, worth $109.4 billion as of March 2026, making him the 18th richest person in the world.
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. Bloomberg, who has signed the Giving Pledge, has given away $24.5 billion (as of 2025) to philanthropic causes in his lifetime. 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 109th mayor of New York City in 2001. He held office for three consecutive terms, winning re-election in 2005 and 2009. Pursuing socially liberal and fiscally moderate policies, Bloomberg developed a technocratic managerial style.
As the mayor of New York, Bloomberg established public charter schools, rebuilt urban infrastructure, and supported gun control, public health initiatives, and environmental protections. He also led a re-zoning of large areas of the city, which facilitated widespread new commercial and residential construction after the September 11 attacks. Bloomberg is considered to have had far-reaching influence on the politics, 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.

Bloomberg was born on February 14, 1942, at St. Elizabeth's Hospital, in the Brighton neighborhood of Boston, to William Henry Bloomberg, a bookkeeper for a dairy company, and Charlotte (née Rubens) Bloomberg. His father never earned more than $6,000 (equivalent to $110,000 in 2026 dollars) a year. William Henry Bloomberg died suddenly when his son was in college. The Bloomberg Center at the Harvard Business School was named in William Henry's honor. Bloomberg's family is Jewish, and he is a member of the Temple Emanu-El in Manhattan. Bloomberg's paternal grandfather, Rabbi Alexander "Elick" Bloomberg, was a Polish Jew. Bloomberg's maternal grandfather, Max Rubens, was a Lithuanian Jewish immigrant from present-day Belarus, and his maternal grandmother was born in New York to Lithuanian Jewish parents.
The family lived in Allston until Bloomberg was two years old, followed by Brookline, Massachusetts, for two years, finally settling in the Boston suburb of Medford, Massachusetts, where he lived until after he graduated from college.
Bloomberg became an Eagle Scout when he was twelve years old. He graduated from Medford High School in 1960. He went on to attend Johns Hopkins University, where he joined the fraternity Phi Kappa Psi. While there, he constructed the blue jay costume for the university's mascot. He graduated in 1964 with a Bachelor of Science in Engineering degree in electrical engineering. In 1966, he graduated from Harvard Business School with a Master of Business Administration (MBA) degree.
Bloomberg is a member of Kappa Beta Phi and Tau Beta Pi. He wrote an autobiography, Bloomberg by Bloomberg, with help from Bloomberg News editor-in-chief Matthew Winkler.

Johns Hopkins University philanthropy
As of 2024, Bloomberg has given more than $4.55 billion to Johns Hopkins University, his alma mater, making him "the most generous living donor to any education institution in the United States." His first contribution, in 1965, had been $5. He made his first $1 million commitment to JHU in 1984, and subsequently became the first individual to exceed $1 billion in lifetime donations to a single U.S. institution of higher education.
Bloomberg's contributions to Johns Hopkins "fueled major improvements in the university's reputation and rankings, its competitiveness for faculty and students, and the appearance of its campus," and included construction of a children's hospital (the Charlotte R. Bloomberg Children's Center Building, named after Bloomberg's mother); a physics building, a school of public health (the Johns Hopkins Bloomberg School of Public Health), libraries, and biomedical research facilities, including the Institute for Cell Engineering, a stem-cell research institute within the School of Medicine, and the Malaria Research Institute within the School of Public Health. In 2013, Bloomberg committed $350 million to Johns Hopkins, five-sevenths of which were allocated to the Bloomberg Distinguished Professorships. In 2016, Bloomberg Philanthropies contributed $300 million to establish the Bloomberg American Health Initiative. Bloomberg also funded the launch of the Bloomberg–Kimmel Institute for Cancer Immunotherapy within the Johns Hopkins School of Medicine in East Baltimore, with a $50 million gift; an additional $50 million was given by philanthropist Sidney Kimmel, and $25 million by other donors. It will support cancer therapy research, technology and infrastructure development, and private sector partnerships. In 2016, Bloomberg joined Vice President Joe Biden for the institute's formal launch, embracing Biden's "Cancer Moonshot" initiative, which seeks to find a cure for cancer through national coordination of government and private sector resources. In 2018, Bloomberg contributed a further gift of $1.8 billion to Johns Hopkins, allowing the university to practice need-blind admission and meet the full financial need of admitted students.
In 2024, Bloomberg announced a $1 billion gift to Johns Hopkins University to make tuition free for all medical school students whose families make under $300,000 a year, beginning in the fall of 2024. The donation also increased financial aid for students enrolled in nursing, public health and other graduate programs.
Other educational and research philanthropy
In 1996, Bloomberg endowed the William Henry Bloomberg Professorship at Harvard University with a $3 million gift in honor of his father, who died in 1963, saying: "Throughout his life, he recognized the importance of reaching out to the non-profit sector to help better the welfare of the entire community."
In 2015, Bloomberg donated $100 million to Cornell Tech, the applied sciences graduate school of Cornell University on the school's Roosevelt Island campus. Through Bloomberg Philanthropies, Bloomberg established the American Talent Initiative in 2016 which is committed to increasing the number of lower-income high-achieving students attending elite colleges. Bloomberg Philanthropies also supports CollegePoint which has provided advising to lower- and moderate-income high school students since 2014. In 2016, the Museum of Science, Boston, announced a $50 million gift from Bloomberg. Bloomberg credited the museum with sparking his intellectual curiosity as a patron and student during his youth in Medford, Massachusetts. It is the largest donation in the museum's 186-year history.
Bloomberg donated $100 million to America's four Historically Black Medical Schools in 2020 as part of Bloomberg Philanthropies' Greenwood Initiative, which tackles the racial wealth gap and addresses decades of under-investment in Black communities. The gift to Meharry Medical College, Howard University College of Medicine, Morehouse School of Medicine and Charles R. Drew University of Medicine and Science provided grants to reduce debt for students, meaning many medical students enrolled at the time and for the four years to follow would graduate free of debt.
In April 2022, Bloomberg announced two separate $100 million donations, one to Harlem Children's Zone's Promise Academy and another to Success Academy Charter Schools.
In 2024, Bloomberg again made a donation to the nation's Historically Black Medical Schools — this time gifting $600 million to the four schools to support their endowments. The New York Times reported the endowments were "significantly underfunded" due to entrenched discrimination, but Bloomberg's gift was expected to increase three of the schools' endowment sizes by more than 100%. The donation also included $5 million to help Xavier University to establish a new medical school.
In 2025, Bloomberg expanded his support of HBCU education by funding a $20 million initiative to develop K-12 charter schools on HBCU campuses and establish a direct pipeline of quality educational opportunities.

In 1966, Bloomberg was hired for a job earning $9,000 per year at Salomon Brothers, a large Wall Street investment bank. Salomon Brothers later promoted him to the equities desk. Bloomberg became a general partner at Salomon Brothers in 1972; he headed equity trading and, later, systems development. Phibro Corporation bought Salomon Brothers in 1981, and the new management fired Bloomberg, paying him $10 million for his equity in the firm.
Using the money he received from Phibro, Bloomberg—having designed in-house computerized financial systems for Salomon—set up a data services company named Innovative Market Systems (IMS) based on his belief that Wall Street would pay a premium for high-quality business information, delivered instantaneously on computer terminals in a variety of usable formats. The company sold customized computer terminals that delivered real-time market data, financial calculations and other analytics to Wall Street firms. The terminal, first called the Market Master terminal, was released to market in December 1982.
In 1986, IMS renamed itself Bloomberg L.P. Over the years, ancillary products including Bloomberg News, Bloomberg Radio, Bloomberg Message, and Bloomberg Tradebook were launched. Bloomberg, L.P. had revenues of approximately $10 billion in 2018. As of 2019, the company has more than 325,000 terminal subscribers worldwide and employs 20,000 people in dozens of locations.
In the 1980s and 1990s, Bloomberg L.P. was compared to a fraternity, with employees bragging in the company's office about their sexual exploits. The company was sued four times by female employees for sexual harassment, including one incident in which a victim claimed to have been raped. To celebrate Bloomberg's 48th birthday, colleagues published a pamphlet entitled The Portable Bloomberg: The Wit and Wisdom of Michael Bloomberg. Among various sayings that were attributed to him, several have subsequently been criticized as sexist or misogynistic. Among the contents of the 1990 publication are a suggestion that if women wanted to be known for their intelligence, they would spend less time at Bloomingdale's and more at the library; as well as a joke that if Bloomberg terminals could provide oral sex, it would put female employees out of work. Bloomberg's staff told the New York Times that he now regrets having made such "disrespectful" remarks.
When he left the position of CEO to pursue a political career as the mayor of New York City, Bloomberg was replaced by Lex Fenwick and later by Daniel L. Doctoroff, after his initial service as deputy mayor under Bloomberg. After completing his final term as the mayor of New York City, Bloomberg spent his first eight months out of office as a full-time philanthropist. In fall 2014, he announced that he would return to Bloomberg L.P. as CEO at the end of 2014, succeeding Doctoroff, who had led the company since February 2008. Bloomberg resigned as CEO of Bloomberg L.P. to run for president in 2019.
In January 2024, John P. Angelos reached a $1.725 billion deal to sell the Baltimore Orioles to a group led by David Rubenstein. The group included Bloomberg, former Baltimore Mayor Kurt Schmoke, Cal Ripken, New York investment manager Michael Arougheti and NBA legend Grant Hill.

Wealth
In March 2009, Forbes reported Bloomberg's wealth at $16 billion, a gain of $4.5 billion over the previous year, the world's biggest increase in wealth from 2008 to 2009. Bloomberg moved from 142nd to 17th in the Forbes list of the world's billionaires in only two years. In the 2019 Forbes list of the world's billionaires, he was the ninth-richest person; his net worth was estimated at $55.5 billion. In 2021, Bloomberg's net worth was estimated at $106 billion, ranking him 12th on Forbes' list of billionaires.
Tobacco, gun control, and public health
Bloomberg has been a long-time donor to global tobacco control efforts. Bloomberg has donated close to $1 billion to the World Health Organization (WHO) to promote anti-smoking efforts, including $125 million in 2006, $250 million in 2008, and $360 million, making Bloomberg Philanthropies the developing world's biggest funder of tobacco-control initiatives. In 2013, it was reported that Bloomberg had donated $109.24 million in 556 grants and 61 countries to campaigns against tobacco. Bloomberg's contributions are aimed at "getting countries to monitor tobacco use, introduce strong tobacco-control laws, and create mass media campaigns to educate the public about the dangers of tobacco use". Bloomberg Philanthropies and the Campaign for Tobacco-Free Kids jointly launched a $160 million, three-year campaign against youth use of electronic cigarettes (vaping).
Bloomberg is the co-founder of Everytown for Gun Safety (formerly Mayors Against Illegal Guns), a gun control advocacy group.
In 2016, the World Health Organization appointed Bloomberg as its Global Ambassador for Noncommunicable Diseases.

Family and relationships
In 1975, Bloomberg married Susan Elizabeth Barbara Brown, a British national from Yorkshire, United Kingdom. They have two daughters: Emma Beth (born c. 1979), and Georgina Leigh (born 1983), who were featured on Born Rich, a 2003 documentary film about the children of the extremely wealthy. Bloomberg divorced Brown in 1993, but he has said she remains his "best friend". Since 2000, Bloomberg has lived with former New York state banking superintendent Diana Taylor. Emma Bloomberg was married to Chris Frissora, son of Mark Frissora, and they had a daughter with a hybrid surname, Frissberg.
Bloomberg's younger sister, Marjorie Tiven, has been commissioner of the New York City Commission for the United Nations, Consular Corps, and Protocol, since February 2002.
Relations with the Sackler family
During the opioid epidemic in the United States, Mortimer Sackler — son of a co-founder of the company, Purdue Pharma, and a member of its board, met with Bloomberg to "seek his help and guidance on the current issues we are facing". Purdue's head of communications, Josephine Martin, added "Any positive news or ability to get our side out is through Bloomberg. We have given them exclusives and they have treated us very well." Bloomberg also advised Mortimer Sackler to consult Stu Loeser to help manage communications.
Religion
Although he attended Hebrew school, had a bar mitzvah, and his family kept a kosher kitchen, Bloomberg today lives a mostly secular religious life, attending synagogue mainly during the High Holidays and a Passover Seder with his sister, Marjorie Tiven. Neither of his daughters had bat mitzvahs, nor does either daughter follow a religiously Jewish lifestyle, such as abiding kosher dietary restrictions or keeping the Jewish sabbath.
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". On various occasions, Bloomberg allegedly commented, "I'd do her", regarding certain women, some of whom were co-workers or employees. Bloomberg later said that by "do", he meant that he would have a personal relationship with the woman.
During his term as mayor, he lived at his own home on the Upper East Side of Manhattan, instead of Gracie Mansion, the official mayoral residence. In 2013, he owned 13 properties in various countries around the world, including a $20 million Georgian mansion in Southampton, New York. In 2015, he acquired 4 Cheyne Walk, a historical property in Cheyne Walk, Chelsea, London, which once belonged to writer George Eliot. Bloomberg and his daughters own houses in Bermuda, and stay there frequently.
Bloomberg stated that during his mayoralty, he rode the New York City Subway on a daily basis, particularly in the commute from his 79th Street home to his office at City Hall. An August 2007 story in The New York Times stated that he was often seen chauffeured by two New York Police Department-owned SUVs to an express train station to avoid having to change from the local to the express trains on the IRT Lexington Avenue Line. He supported the construction of the 7 Subway Extension and the Second Avenue Subway; in December 2013, Bloomberg took a ceremonial ride on a train to the new 34th Street station to celebrate a part of his legacy as mayor.
During his tenure as mayor, Bloomberg made cameos, playing himself in the films The Adjustment Bureau and New Year's Eve, as well as in episodes of 30 Rock, Curb Your Enthusiasm, The Good Wife, and two episodes of Law & Order.
Bloomberg is a private pilot. He owns six airplanes: three Dassault Falcon 900s, a Beechcraft B300, a Pilatus PC-24, and a Cessna 182 Skylane. Bloomberg also owns two helicopters: an AW109, and an Airbus helicopter; and, as of 2012, was near the top of the waiting list for an AW609 tiltrotor aircraft. In his youth, he was a licensed amateur radio operator, was proficient in Morse code, and built ham radios.
Bloomberg's fortune is managed by Willett Advisors, an investment firm that serves as his family office.

Philanthropy
In August 2010, Bloomberg signed The Giving Pledge, whereby the wealthy pledge to give away at least half of their wealth. In his lifetime, he has given away $24.5 billion overall, including $4.3 billion in 2025. He was listed as America's highest giving philanthropist, according to Chronicle of Philanthropy, for three consecutive years 2023–2025. He has been in the top ten on the publication's list of America's biggest donors since 2004.
His Bloomberg Philanthropies foundation focuses on public health, the arts, government innovation, the environment, and education. Through the foundation, he donated or pledged $767 million in 2018, and more than $1 billion in 2019.
In 2011, recipients included the Campaign for Tobacco-Free Kids; Centers for Disease Control and Prevention; Johns Hopkins Bloomberg School of Public Health; World Lung Foundation and the World Health Organization. According to The New York Times, Bloomberg was an "anonymous donor" to the Carnegie Corporation from 2001 to 2010, with gifts ranging from $5 million to $20 million each year. The Carnegie Corporation distributed these contributions to hundreds of New York City organizations ranging from the Dance Theatre of Harlem to Gilda's Club, a non-profit organization that provides support to people and families living with cancer. He continues to support the arts through his foundation.
Bloomberg gave $254 million in 2009 to almost 1,400 nonprofit organizations, saying, "I am a big believer in giving it all away and have always said that the best financial planning ends with bouncing the check to the undertaker."

COVID-19 response
During the 2020 COVID-19 pandemic and its aftermath, Bloomberg through his foundation committed to a wide range of urgent causes including researching treatments and vaccines, leading contact tracing to root out the virus, supporting the World Health Organization, and funding global efforts to fight the spread of the disease and protect vulnerable populations. Action included:
Cofounding a $75 million fund for nonprofits impacted by COVID-19 in New York City
Donating $6 million to World Central Kitchen to serve meals to health care workers in New York City
Partnering with Johns Hopkins University to train COVID-19 contact tracers through its school of public health and search for a treatment of the virus.
Convening mayors through a partnership with Harvard College to learn and discuss their pandemic response, featuring a bipartisan roster of speakers and attendees.
Leading New York's contact tracing effort
Launching an information and action sharing network for cities through the National League of Cities
Supporting international efforts to combat the spread of COVID-19 and prepare regional leaders through the International Rescue Committee, the World Health Organization, Vital Strategies and other partners
Environmental advocacy
Bloomberg is an environmentalist and has advocated policy to fight climate change at least since he became the mayor of New York City. Between 2015 and 2025, Bloomberg pledged over $3 billion to environmental efforts and policies. In September 2023, the New York Times called Bloomberg "perhaps the world's single largest funder of climate activism." At the national level, Bloomberg has consistently pushed for transitioning the United States' energy mix from fossil fuels to clean energy. In July 2011, Bloomberg Philanthropies donated $50 million to Sierra Club's Beyond Coal campaign, allowing the campaign to expand its efforts to shut down coal-fired power plants from 15 states to 45 states. In 2015, Bloomberg announced an additional $30 million contribution to the Beyond Coal initiative, matched with another $30 million by other donors, to help secure the retirement of half of America's fleet of coal plants by 2017. In July 2017, Europe Beyond Coal was established to phase out use of coal on the continent by 2030. Austria closed its final coal-fired plant in April 2020. In early June 2019, Bloomberg pledged $500 million to reduce climate impacts and shut remaining coal-fired power plants by 2030 via the new Beyond Carbon initiative. In September 2023, Bloomberg committed another $500 million to Beyond Carbon to "finish the job on coal."
Bloomberg Philanthropies awarded a $6 million grant to the Environmental Defense Fund in support of strict regulations on fracking in the 14 states with the heaviest natural gas production.
In 2013, Bloomberg and Bloomberg Philanthropies launched the Risky Business initiative with former Treasury Secretary Hank Paulson and hedge-fund billionaire Tom Steyer. The joint effort worked to convince the business community of the need for more sustainable energy and development policies, by quantifying and publicizing the economic risks the United States faces from the impact of climate change. In January 2015, Bloomberg led Bloomberg Philanthropies in a $48-million partnership with the Heising-Simons family to launch the Clean Energy Initiative. The initiative supports state-based solutions aimed at ensuring America has a clean, reliable, and affordable energy system.
Since 2010, Bloomberg has taken an increasingly global role on environmental issues. From 2010 to 2013, he served as the chairman of the C40 Cities Climate Leadership Group, a network of the world's biggest cities working together to reduce carbon emissions. During his tenure, Bloomberg worked with President Bill Clinton to merge C40 with the Clinton Climate Initiative, with the goal of amplifying their efforts in the global fight against climate change worldwide. He serves as the president of the board of C40 Cities. In January 2014, Bloomberg began a five-year commitment totaling $53 million through Bloomberg Philanthropies to the Vibrant Oceans Initiative. The initiative partners Bloomberg Philanthropies with Oceana, Rare, and Encourage Capital to help reform fisheries and increase sustainable populations worldwide. In 2018, Bloomberg joined Ray Dalio in announcing a commitment of $185 million towards protecting the oceans.
In 2014, United Nations Secretary General Ban Ki-moon appointed Bloomberg as his first Special Envoy for Cities and Climate Change to help the United Nations work with cities to prevent climate change. In September 2014, Bloomberg convened with Ban and global leaders at the UN Climate Summit to announce definite action to fight climate change in 2015. In 2018, Ban's successor António Guterres appointed Bloomberg as UN envoy for climate action. He resigned in November 2019, in the run-up to his presidential campaign. On 5 February 2021, however, he was re-appointed by Guterres as his Special Envoy on Climate Ambition and Solutions in the lead-up to the climate conference in Scotland scheduled for November 2021.
In late 2014, Bloomberg, Ban Ki-moon, and global city networks ICLEI-Local Governments for Sustainability (ICLEI), C40 Cities Climate Leadership Group (C40) and United Cities and Local Governments (UCLG), with support from UN-Habitat, launched the Compact of Mayors, a global coalition of mayors and city officials pledging to reduce local greenhouse gas emissions, enhance climate resilience, and track their progress transparently. To date, over 250 cities representing more than 300 million people worldwide and 4.1 percent of the total global population, have committed to the Compact of Mayors, which was merged with the Covenant of Mayors in June 2016.
In 2015, Bloomberg and Paris mayor Anne Hidalgo created the Climate Summit for Local Leaders. which convened assembled hundreds of city leaders from around the world at Paris City Hall to discuss fighting climate change. The Summit concluded with the presentation of the Paris Declaration, a pledge by leaders from assembled global cities to cut carbon emissions by 3.7 gigatons annually by 2030.
During the 2015 UN Climate Change Conference in Paris, Mark Carney, Governor of the Bank of England and chair of the Financial Stability Board, announced that Bloomberg would lead a new global task force designed to help industry and financial markets understand the growing risks of climate change.
Following President Donald Trump's announcement that the U.S. government would withdraw from the Paris climate accord, Bloomberg outlined a coalition of cities, states, universities and businesses that had come together to honor America's commitment under the agreement through 'America's Pledge'. Bloomberg offered up to $15 million to the UNFCCC, the UN body that assists countries with climate change efforts. About a month later, Bloomberg and California Governor Jerry Brown announced that the America's Pledge coalition would work to "quantify the actions taken by U.S. states, cities and business to drive down greenhouse gas emissions consistent with the goals of the Paris Agreement." In announcing the initiative, Bloomberg said "the American government may have pulled out of the Paris agreement, but American society remains committed to it." Two think tanks, World Resource Institute and the Rocky Mountain Institute, will work with America's Pledge to analyze the work cities, states and businesses do to meet the U.S. commitment to the Paris agreement.
In May 2019, Bloomberg announced a 2020 Midwestern Collegiate Climate Summit in Washington University in St. Louis with the aim to bring together leaders from Midwestern universities, local government and the private sector to reduce climate impacts in the region.
Expanding on the work of Beyond Coal and Beyond Carbon, Bloomberg launched Beyond Petrochemicals in September 2022. The campaign takes aim at the rapid expansion of U.S. petrochemicals and plastic pollution. The $85 million campaign aims to block the construction of 120 proposed petrochemical projects in Louisiana, Texas and the Ohio River Valley.
Bloomberg serves as global adviser to the winners of the Earthshot Prize. His foundation Bloomberg Philanthropies is a founding partner of the Prize which awards £1,000,000 to each of five winners each year whose work will achieve ambitious climate and sustainability goals by 2030. The 2023 finalists were announced at the Earthshot Prize Innovation Summit in September 2023 in New York, and the five winners were announced in November 2023 in Singapore.
Urban innovation philanthropy
In July 2011, Bloomberg launched a $24 million initiative to fund "Innovation Delivery Teams" in five cities. The teams are one of Bloomberg Philanthropies' key goals: advancing government innovation. In December 2011, Bloomberg Philanthropies launched a partnership with online ticket search engine SeatGeek to connect artists with new audiences. Called the Discover New York Arts Project, the project includes organizations HERE, New York Theatre Workshop, and the Kaufman Center.
In 2013, Bloomberg announced the Mayors Challenge competition to drive innovation in American cities. The program was later expanded to competitions in Latin America and Europe.
In 2016, Bloomberg gave Harvard $32 million to create the Bloomberg Harvard City Leadership Initiative within Harvard Kennedy School's Ash Center for Democratic Governance and Innovation; the initiative provides training to mayors and their aides on innovative municipal leadership and challenges facing cities. Since its founding, 275 mayors and more than 400 top city aides have gone through the program, prompting Time Magazine to call Bloomberg "the nation's mayoral tutor".
In March 2021, Bloomberg gave Harvard $150 million to create the Bloomberg Center for Cities to support mayors.
National September 11 Memorial and Museum
In October 2006, Bloomberg became chairman of the board and chief fundraiser of the National September 11 Memorial & Museum; CBS News and Politico credited him with having resolved financial and design obstacles that delayed its completion. He was mayor during the initial planning stages of the memorial & museum. Once he assumed the Chairmanship, he sought to reduce cost increases, finalize fundraising efforts, and resume the mapping and design processes. Bloomberg has raised $450 million for the National September 11 Memorial & Museum, including a $50 million personal contribution, making him its largest single donor. Bloomberg secured donations from major corporations by saying they held some responsibility as members of the global community. One of his first acts as chairman was securing a $10 million donation from American Express. Bloomberg recruited members to the board and donations across the political spectrum, including David Koch and Jon Stewart. Bloomberg is also chairman of the Perelman Performing Arts Center in the World Trade Center complex, to which he has donated $130 million.
At the ceremony opening for the National September 11 Memorial Museum, Bloomberg said the museum was "a reminder to us and all future generations that freedom carries heavy responsibilities". He continued to lead the annual 9/11 ceremony after leaving office. In 2010 he replanted the Callery Pear tree that had been originally planted in the World Trade Center complex and was discovered in the rubble and saved after the attacks. In September 2021, marking the 20th anniversary of the attacks, Bloomberg and the museum launched The Never Forget Fund, focused on educational programming about 9/11.
Other philanthropy
Through Bloomberg Philanthropies, Bloomberg supported the Fresh Air Fund's creation of 'Open Spaces in the City' in summer 2020 to provide socially-distant areas for kids to play during the COVID-19 pandemic, as well as jobs for local teens. He donated $3 million to the construction of a new public library in his hometown of Medford and $75 million for The Shed, a new arts and cultural center in Hudson Yards, Manhattan.
In September 2023, the Perelman Performing Arts Center opened with $130 million of support from Bloomberg, who serves as its chair. The $500 million art center is the final major piece of the redevelopment of the site where the World Trade Center once stood.
Following the Hamas attack on Israel in October 2023, Bloomberg committed to matching donations to the Israeli Red Cross, known as Magen David Adom. By October 19, 2023, Bloomberg had matched $25 million in donations to the ambulance and Medivac services.
Bloomberg also endowed his hometown synagogue, Temple Shalom, which was renamed for his parents as the William and Charlotte Bloomberg Jewish Community Center of Medford.
Bloomberg hosted the Global Business Forum in 2017, during the annual meeting of the United Nations General Assembly; the gathering featured international CEOs, heads of state, and other prominent speakers.
In 2009, Bloomberg met with fellow billionaires, including Warren Buffett, Bill Gates, Ted Turner and Oprah Winfrey, to address issues ranging from the environment, health care and concerns over population growth. Although no formal organization was established, the effort was understood to be designed to help bring various philanthropic projects of the mega-donors into a more unified effort.

Bloomberg was frequently mentioned as a possible centrist candidate for the presidential elections in 2008 and 2012, as well as for governor of New York in 2010 or vice-president in 2008.
In the immediate aftermath of Hurricane Sandy in November 2012, Bloomberg penned an op-ed officially endorsing Barack Obama for president, citing Obama's policies on climate change.
2016 elections
On January 23, 2016, it was reported that Bloomberg was again considering a presidential run, as an independent candidate in the 2016 election, if Bernie Sanders got the Democratic party nomination. This was the first time he had officially confirmed he was considering a run. Bloomberg supporters believed that Bloomberg could run as a centrist and capture many voters who were dissatisfied with the likely Democratic and Republican nominees. However, on March 7, Bloomberg announced he would not be running for president.
In July 2016, Bloomberg delivered a speech at the 2016 Democratic National Convention in which he called Hillary Clinton "the right choice". Bloomberg warned of the dangers a Donald Trump presidency would pose. He said Trump "wants you to believe that we can solve our biggest problems by deporting Mexicans and shutting out Muslims. He wants you to believe that erecting trade barriers will bring back good jobs. He's wrong on both counts." Bloomberg also said Trump's economic plans "would make it harder for small businesses to compete", and would "erode our influence in the world". Trump responded to the speech by condemning Bloomberg in a series of tweets.

2018 elections
In June 2018, Bloomberg pledged $80 million to support Democratic congressional candidates in the 2018 election, with the goal of flipping control of the Republican-controlled House to Democrats. In a statement, Bloomberg said that Republican House leadership were "absolutely feckless" and had failed to govern responsibly. Bloomberg advisor Howard Wolfson was chosen to lead the effort, which was to target mainly suburban districts. By early October, Bloomberg had committed more than $100 million to returning the House and Senate to Democratic power, fueling speculation about a presidential run in 2020. On October 10, 2018, Bloomberg announced that he had returned to the Democratic Party.
2020 presidential campaign
On March 5, 2019, Bloomberg announced that he would not run for president in 2020. Instead, he encouraged the Democratic Party to "nominate a Democrat who will be in the strongest position to defeat Donald Trump." However, due to his dissatisfaction with the Democratic field, Bloomberg reconsidered. He officially launched his campaign for the 2020 Democratic nomination on November 24, 2019.
Bloomberg self-funded his campaign from his personal fortune and did not accept campaign contributions.
Bloomberg's campaign suffered from his lackluster performance in two televised debates. When Bloomberg participated in his first presidential debate, Senator Elizabeth Warren challenged him to release women from non-disclosure agreements relating to their allegations of sexual harassment at Bloomberg L.P. Two days later, Bloomberg announced that there were three women who had made complaints concerning him, and added that he would release any of the three if they requested. Warren continued her attack in the second debate the next week. Others criticized Bloomberg for his wealth and campaign spending, as well as his former affiliation with the Republican Party.
As a late entrant to the race, Bloomberg skipped the first four state primaries and caucuses. He spent over $1 billion of his personal fortune on the primary campaign, more than all other Democratic candidates combined at that stage. Bloomberg said he wanted to spent so much money as an "investment" into removing or at least trying to unseat President Trump from the White House. His campaign blanketed the country with campaign advertisements on broadcast and cable television, the Internet, and radio, as well as direct mail. Bloomberg also spent heavily on campaign operations that grew to 200 field offices and more than 2,400 paid campaign staffers. His support in nationwide opinion polls never exceeded 15 percent, but stagnated or dropped before Super Tuesday, while former vice president Joe Biden became the frontrunner after receiving the support of major candidates Pete Buttigieg and Amy Klobuchar. Bloomberg suspended his campaign on March 4, 2020, after a disappointing Super Tuesday in which he won only American Samoa. Multiple former campaign staffers sued Bloomberg alleging that he promised his employees to be paid through the election but they were fired instead after the candidate dropped out. Five years later, a Massachusetts man working for his campaign won $90,000 in back pay plus interest.
After dropping out from the presidential race, Bloomberg endorsed Biden. Bloomberg donated $18 million to the Democratic National Committee and publicly planned a "massive spending blitz" to support Biden's campaign. Speaking on the final night of the 2020 Democratic National Convention, Bloomberg took aim at Trump's handling of the COVID-19 pandemic and the American economy: "Would you rehire or work for someone who ran your business into the ground? Who always does what's best for him or her, even when it hurts the company, and whose reckless decisions put you in danger, and who spends more time tweeting than working? If the answer is no, why the hell would we ever rehire Donald Trump for another four years?"
Defense Innovation Board
In February 2022, Bloomberg was nominated to chair the Defense Innovation Board, being sworn in on June 22, 2022.
Political contributions
As of August 2026, Bloomberg spent $19.8 million in support of Democratic candidates in the 2026 United States elections.
Political positions
Bloomberg was a Democrat until 2001, when he switched to the Republican Party to run for mayor. He switched to an independent in 2007, and registered again as a Democrat in October 2018. In 2004, he endorsed the re-election of George W. Bush, and spoke at the 2004 Republican National Convention. He endorsed Barack Obama's re-election in 2012, endorsed Hillary Clinton in the 2016 election, and spoke at the 2016 Democratic National Convention. In 2008, he did not make a presidential election endorsement, but he voted for Obama, according to a 2020 statement by "Stu Loeser, a Bloomberg [2020] campaign spokesman".
As Mayor of New York, Bloomberg supported government initiatives in public health and welfare. This included tobacco control efforts (including an increase in the legal age to purchase tobacco products, a ban on smoking in indoor workplaces, and an increase in the cigarette tax); the elimination of the use of artificial trans fats in restaurants; and bans on all flavored tobacco and e-cigarette products including menthol flavors. Bloomberg also launched an unsuccessful effort to ban on certain large (more than 16 fluid ounce) sugary sodas at restaurants and food service establishments in the city. These initiatives were supported by public health advocates, but were criticized by some as "nanny state" policies.
Over his career, Bloomberg has "mingled support for progressive causes with more conservative positions on law enforcement, business regulation, and school choice". Bloomberg supports gun-control measures, abortion rights, same-sex marriage, and a pathway to citizenship for illegal immigrants. He advocates for a public health insurance option that he has called "Medicare for all for people that are uncovered", rather than a universal single-payer healthcare system. He is concerned about climate change, and has touted his mayoral efforts to reduce greenhouse gases. Bloomberg supported the Iraq War, and opposed creating a timeline for withdrawing troops. Bloomberg has sometimes embraced the use of surveillance in efforts to deter crime and protect the public against terrorism.
During, and after, his tenure, he was a staunch supporter of stop-and-frisk. In November 2019, Bloomberg apologized for supporting it. He advocates reversing many of the Trump tax cuts. His own tax plan includes implementing a 5 percent surtax on incomes above $5 million a year, and would raise federal revenue by $5 trillion over a decade. He opposes a wealth tax, saying that it would likely be found unconstitutional. He has also proposed more stringent financial regulations that include tougher oversight for big banks, a financial transactions tax, and stronger consumer protections. He supported decreasing estate-tax threshold to collect more estate taxes and close tax avoidance schemes. According to ProPublica investigation, he set up multiple GRATs, thus shielding parts of his fortune for his heirs.
Bloomberg stated that running as a Democrat – not an independent – was the only path he saw to defeating Donald Trump, saying: "In 2020, the great likelihood is that an independent would just split the anti-Trump vote and end up re-electing the President. That's a risk I refused to run in 2016, and we can't afford to run it now."
In the 2020 general election, Bloomberg invested $115 million in Joe Biden's campaign in key states like Florida, Ohio, and Texas, contributed millions to various Democrats in local races, and raised over $16 million to clear court fines for nearly 32,000 Black and Hispanic Florida voters with felony convictions. Bloomberg contributed $19 million to a pro-Biden super PAC in support of Biden's reelection in 2024. In October 2024, Bloomberg contributed $50 million to support Kamala Harris's 2024 election campaign.
