Jamie Dimon

James Dimon ( DY-mən; born March 13, 1956) is an American banker and manager who has been the chief executive officer (CEO) of JPMorgan Chase since 2005 (chairman since 2006).

Dimon began his career as a management consultant at a consulting firm in Boston. After graduating from Harvard Business School in 1982, he joined American Express, working under the mentorship of Sandy Weill. In 1986, at the age of 30, Dimon was appointed chief financial officer (CFO) of Commercial Credit and later became the firm's president. He was chief operating officer (COO) of both the insurer Travelers and the brokerage firm Smith Barney from 1990 to 1998, when he became president of Citigroup. In 2000, he was appointed CEO of Bank One, overseeing its operations until merger with JPMorgan Chase in 2004. Dimon then became COO of JPMorgan Chase, assuming the role of CEO in 2005.

He was on the board of directors of the Federal Reserve Bank of New York during the late 2010s. Dimon was included in Time magazine's 2006, 2008, 2009, and 2011 lists of the world's 100 most influential people. As of December 2025, Forbes estimates his net worth at $3 billion.

Dimon was born on March 13, 1956, in New York City. He grew up in the Jackson Heights neighborhood of Queens. He is one of three sons of Theodore and Themis (née Kalos) Dimon, who were both Greek by ancestry. His paternal grandfather was a Greek immigrant who had worked as a banker in Smyrna and Athens, and later changed the family name from Papademetriou to Dimon. Dimon has an older brother, Peter, and a fraternal twin brother, Ted. Both his father and grandfather were stockbrokers at Shearson.

Dimon attended secondary school at the Browning School, a private boys' prep school on the Upper East Side of Manhattan. He then studied economics and psychology at Tufts University, graduating in 1978 with a Bachelor of Arts degree, summa cum laude. At Tufts, he wrote a paper on Shearson's mergers, which his mother sent to Sandy Weill, who then hired Dimon to work at Shearson during a summer break, doing budgets.

After working as a management consultant at the Management Analysis Center in Boston from 1978 to 1980, Dimon enrolled at Harvard Business School. He worked at Goldman Sachs during the summer between his first and second years. Dimon graduated from Harvard in 1982 with an Master of Business Administration (MBA) degree, and received Baker Scholar honors for graduating in the top 5% of his class.

After receiving his MBA, Dimon was convinced by Sandy Weill to turn down offers from Goldman Sachs, Morgan Stanley, and Lehman Brothers to join Weill as an assistant at American Express. Although Weill could not offer the same amount of money as the investment banks, Weill promised Dimon that he would have "fun." Dimon's father, Theodore, was an executive vice president at American Express.

Sandy Weill left American Express in 1985, and Dimon followed him. The two then took over Commercial Credit, a consumer finance company, from Control Data. At age 30, Dimon was appointed CFO, helping turn around the company.

In 1998, through a series of mergers and acquisitions, Dimon and Weill formed a large financial services conglomerate: Citigroup. But Dimon left Citigroup in November 1998, after Weill asked him to resign during a weekend executive retreat. Rumors at the time suggested that he and Weill had argued, in 1997, over Dimon's inaction to promote Weill's daughter, Jessica M. Bibliowicz, although that happened more than a year before Dimon's departure. At least one other account cites, as the real reason, a request by Dimon to be treated as an equal.

In March 2000, Dimon became CEO of Bank One, the United States' fifth largest bank.

When JPMorgan Chase merged with Bank One in July 2004, Dimon became president and COO of the combined company. On December 31, 2005, he was named CEO of JPMorgan Chase, and on December 31, 2006, he was named chairman and president. In March 2008, he was a Class A board member of the Federal Reserve Bank of New York. Under Dimon's leadership, with the acquisitions during his tenure, JPMorgan Chase became the leading U.S. bank in domestic assets under management, market capitalization value and publicly traded stock value. In December 2008, Dimon called the British chancellor, Alistair Darling, to say that the 50% tax on bankers' bonuses over £25,000 (levied in the aftermath of the 2008 financial crisis) was too punitive; documents released in the Epstein files in 2026 show that the then-business secretary, Peter Mandelson, suggested that Dimon "mildly threaten" Darling over the tax. In 2009, Dimon was considered one of "The TopGun CEOs" by Brendan Wood International, an advisory agency.

From 1989 to 2009, Dimon donated primarily to the Democratic Party. In May 2012, he described himself as "barely a Democrat." After Barack Obama won the 2008 presidential election, there was speculation that Dimon would become Secretary of the Treasury. Obama eventually named Timothy Geithner to the position. Following the acquisition of Washington Mutual by JPMorgan Chase, Obama commented on Dimon's handling of the real-estate crash, credit crisis and the banking collapse affecting corporations nationwide, including major financial institutions like Bank of America, Citibank and Wachovia, and said he did "a pretty good job managing an enormous portfolio."

Dimon has had close ties to some people in the Obama White House, including former Chief of Staff Rahm Emanuel. Dimon was one of three CEOs—along with Goldman Sachs Chairman Lloyd Blankfein and Citigroup CEO Vikram Pandit—said by the Associated Press to have had liberal access to former Treasury Secretary Timothy Geithner. Nonetheless, Dimon has often publicly disagreed with some of Obama's policies. During the 2016 United Kingdom European Union membership referendum, JPMorgan Chase, under Dimon's leadership donated large sums of money to the Remain campaign, and Dimon personally campaigned with Chancellor of the Exchequer George Osborne against Brexit.

In December 2016, Dimon joined a business forum assembled by then president-elect Donald Trump to provide strategic and policy advice on economic issues. The forum dissolved after Trump's comments on the alt-right political violence at the 2017 Unite the Right rally. During Trump's presidency, Dimon supported his Tax Cuts and Jobs Act of 2017, but condemned the Trump administration's immigration and trade policies. In a 2019 interview with 60 Minutes, Dimon claimed that the United States "is the most prosperous economy the world has ever seen" despite acknowledging issues such as income inequality and the China–United States trade war. Dimon also criticized the U.S. federal government response to the COVID-19 pandemic under Trump in a letter to shareholders which also criticized the state of education, health care and social safety nets in the United States.

During the 2020 Democratic Party presidential primaries, Dimon criticized the lack of a "strong centrist, pro-business, pro-free enterprise" candidate. In 2018 Dimon "thought about thinking about" starting his own presidential campaign, but decided that it would be too unpopular to succeed. During the 2020 United States presidential election, Dimon wrote a memorandum calling for candidates to respect the democratic process and a peaceful transition of power, writing "While strong opinions and tremendous passion characterized this U.S. election, it is the responsibility of each of us to respect the democratic process, and ultimately, the outcome." Dimon subsequently condemned the 2021 United States Capitol attack. In 2021, Trump complained that Dimon was "not a patriot" because of his company's business in China.

In May–June 2023, Dimon was encouraged by American billionaire and hedge fund manager Bill Ackman to run in the 2024 United States presidential election, after the former expressed his interest in pursuing a public office sometime in the future. Dimon clarified that he has no plans to run for office at this time, and that he is happy with his current leading position in JPMorgan Chase, where he expects to stay for three and a half more years. However, in June 2025 Dimon said his retirement is still "several years away" and that he may stick around longer.

In 1983, Dimon married Judith Kent, whom he met at Harvard Business School. They have three daughters: Julia, Laura, and Kara Leigh. Julia and Kara attended Duke University; Laura is a Barnard College graduate, a freelance journalist, formerly at the New York Daily News, and currently a producer for ABC News.

Dimon was diagnosed with throat cancer in 2014. He received eight weeks of radiation and chemotherapy ending in September 2014. In March 2020, at the age of 63, Dimon underwent emergency heart surgery to repair an acute aortic dissection. According to JP Morgan, Dimon recovered well from surgery, with Gordon Smith and Daniel Pinto running the bank until his return. In April 2020, Dimon returned to work in a remote capacity due to the COVID-19 pandemic.
