Jamie Dimon, CEO of JPMorgan Chase & Co.© Win McNamee/Getty ImagesJames “Jamie” Dimon (born March 13, 1956, New York City, U.S.) is a billionaire businessman and the chair and chief executive officer of JPMorgan Chase & Co. (JPM). He has been called one of the most powerful leaders in corporate America.

　　Early life and educationOne of three children to parents Theodore and Themis Dimon, James—called Jamie—was raised in an environment of financial savvy. His father was a stockbroker and vice president at American Express Co. (AXP), and growing up Dimon learned about the industry “across the kitchen table.” Following his father into the financial world, Dimon received a bachelor’s degree from Tufts University and an MBA from Harvard Business School. There he met Wellesley College alum Judith Kent, whom he married in 1983. The couple has three daughters.

　　“I’ve always said family first, country second, JPMorgan literally last.”

　　Career beginnings with Sandy WeillDimon spent more than a decade of his early career working alongside mentor financier Sanford Weill, who convinced Dimon to reject offers from Goldman Sachs (GS) and Morgan Stanley (MS) to work with him at American Express. In 1985 both Dimon and Weill left American Express to co-lead Travelers Group (then known as Commercial Credit), a financial services conglomerate that merged with Citigroup (C) in 1998. Dimon held several positions at the company, including chief financial officer and president, before Weill ousted him in 1998. “He wanted to be CEO,” Weill later told The New York Times, “and I didn’t want to leave.”

　　The exit from Travelers Group would become a boon for Dimon. In 2000, he accepted the position of CEO at Bank One, which merged with JPMorgan Chase & Co. four years later. Dimon worked as president and chief operating officer before ascending to CEO of Chase in 2006. His strategy was to cut as many costs as possible, ranging from eliminating corporate perks such as tickets to the U.S. Open tennis tournament to slashing regional managers’ salaries. His initiatives were unpopular—an insider told Bloomberg that Dimon was “going down like cod-liver oil”—but successful. Chase weathered the financial market crash of 2008 and by 2011 was the largest bank by assets in the United States. Chase also made Dimon a billionaire. As of January 2025, his net worth was $2.8 billion.

He donated substantially to members of the Democratic Party early in his career, giving more than $500,000 to Democratic candidates from 1989 to 2009, and was allied with the administration of President Barack Obama. Dimon later distanced himself from a strict partisan affiliation. “My heart is Democratic,” he told CNBC in 2019, “but my brain is kind of Republican.” A proponent of free market capitalism, Dimon primarily identifies as a “capitalist” and a “patriot.” This split from party lines solidified when Dimon served on President Donald Trump’s short-lived business advisory council, which Trump disbanded in 2017.

　　Long rumored to have presidential aspirations, Dimon confirmed the speculation in 2016 when he told CNN he would “love to be president” but that a campaign would be “too hard and too late.” Still, Dimon reportedly entertained the idea of a serious presidential run in 2020 as a candidate for either party before ultimately deciding against it. In 2024, Dimon endorsed Nikki Haley in the Republican primary. After Haley lost the nomination to Trump, Dimon began to speak positively about Trump after years of criticism (including once claiming he “could beat” Trump in an election).

　　Rumored cabinet role under TrumpIn July 2024, Trump told Bloomberg Businessweek that, if elected president again later that year, he would consider Dimon for the role of secretary for the U.S. Department of the Treasury. Trump said he had “a lot of respect for Dimon” and Dimon was “someone [Trump] would consider” for the position. But shortly after the interview was published, Trump contested the quote, posting on Truth Social that he had “never discussed, or thought of, Jamie Dimon … for Secretary of the Treasury.” Despite rumors in the financial world that Dimon wanted the job, he didn’t comment on Trump’s statements.
