John Paulson Bio
John Alfred Paulson, born on December 14, 1955, is an American billionaire hedge fund manager and the founder of Paulson & Co., a New York–based investment management firm he established in 1994. Often described as one of the most prominent names in high finance, Paulson rose to worldwide attention in 2007 when he personally earned more than $4 billion by betting against the U.S. subprime mortgage market through credit default swaps. He continues to lead Paulson & Co. and is widely regarded as a defining figure of the modern hedge fund industry.
Beyond his role as a Wall Street investor, John Paulson has built a reputation as a major philanthropist and political donor, channeling hundreds of millions of dollars into universities, cultural institutions, and political campaigns. He earned a Bachelor of Arts in finance from New York University in 1978 and a Master of Business Administration from Harvard Business School in 1980, the academic foundation for a career that began on Park Avenue and now spans more than four decades.
Early Life and Background
John Paulson was born on December 14, 1955, in Queens, New York City, the third of four children born to Alfred G. Paulson and Jacqueline Paulson, whose maiden name was Boklan. His father, originally named Alfredo Guillermo Paulsen, was born in Ecuador to a father of half French and half Norwegian descent and an Ecuadorian mother. Orphaned at fifteen, Alfredo moved to Los Angeles at sixteen, enlisted in the U.S. Army, served and was wounded in Italy during World War II, and later changed his surname from Paulsen to Paulson.
John’s mother, Jacqueline, was the daughter of Jewish immigrants from Lithuania and Romania who had settled in New York City. She met Alfredo while both were students at the University of California, Los Angeles, and the couple later married and moved to New York. Alfredo worked at Arthur Andersen and subsequently served as chief financial officer at the public-relations firm Ruder Finn, giving the family a stable middle-class life in Queens.
As a young man, John Paulson briefly dropped out of college before realizing that a career in sales would not provide dependable income. He returned to New York University in 1976 and quickly distinguished himself in business studies. In 1978, he graduated valedictorian of his class, earning a Bachelor of Arts summa cum laude in finance from New York University’s College of Business and Public Administration.
Path to Hedge Fund Founder
After completing his MBA at Harvard Business School in 1980 on a Sidney J. Weinberg/Goldman Sachs scholarship, graduating as a George F. Baker Scholar in the top five percent of his class, John Paulson began his career at the Boston Consulting Group, where he conducted research and provided corporate advice. Eager to work in investment on Wall Street, he left to join Odyssey Partners, working alongside the influential investor Leon Levy.
Paulson later moved to Bear Stearns, where he served in the mergers and acquisitions department, before joining Gruss Partners LP as a general partner. These formative experiences at leading advisory and investing firms gave him direct exposure to mergers, acquisitions, and event-driven investment strategies that would later define his own approach. In 1994, at the age of 38, he launched Paulson & Co. with $2 million and a single employee.
John Paulson Career
Early Career (1980–1994)
John Paulson’s early professional years were spent moving through some of the most respected names in American finance. After two years at Boston Consulting Group, he joined Odyssey Partners, a firm led by Leon Levy, where he gained hands-on experience in merger arbitrage and event-driven investing. He then transitioned to Bear Stearns, contributing to the mergers and acquisitions practice, before becoming a general partner at Gruss Partners LP.
These positions allowed him to develop the disciplined approach to risk and opportunity that would later shape Paulson & Co. By the early 1990s, he had built a strong network on Wall Street and a clear sense of the strategies he wanted to pursue. In 1994, he made the decision to start his own firm, opening a small office in space rented from Bear Stearns on the 26th floor of 277 Park Avenue.
Paulson & Co. Breakthrough (1994–2006)
From its founding in 1994, Paulson & Co. focused on event-driven investing, an approach that involves taking positions in companies undergoing mergers, acquisitions, spin-offs, and proxy contests. Paulson made hundreds of such investments throughout the late 1990s and early 2000s, gradually growing the firm’s capital base. By 2003, the fund had grown to roughly $300 million in assets under management, reflecting a steady rise in reputation.
The firm relocated to 57th and Madison in 2001 as it expanded its team and operations. Paulson became known for his patience and willingness to take large, concentrated positions when his research identified a clear mismatch between price and value. This disciplined approach laid the groundwork for the trade that would later transform his career and the broader hedge fund industry.
The Subprime Trade Era (2007–Present)
In 2007, John Paulson became a global financial celebrity when he and his firm earned nearly $4 billion personally for him by shorting the U.S. subprime mortgage market. Working with Goldman Sachs, his team created the Abacus 2007-AC1 investment vehicle, and the trade has been described in the financial press as one of the most profitable in market history. By the end of 2007, Paulson had been transformed from an obscure money manager into a financial legend.
Building on that success, Paulson earned $4.9 billion in 2010, primarily by investing in the gold sector. The following year proved more difficult, as losing positions in Bank of America, Citigroup, and Sino-Forest Corporation weighed on the firm’s flagship Paulson Advantage Fund. Paulson has continued to invest heavily in gold, and in 2025 it was reported that an abandoned Idaho gold mine controlled by Paulson is being revived to generate additional returns.
Notable Events and Milestones
Beyond the 2007 subprime trade, John Paulson has been involved in several defining moments on Wall Street, including a proxy fight investment during Yahoo’s 2008 board contest with Carl Icahn. In 2008, he co-wrote a Wall Street Journal op-ed proposing an alternative to the Treasury’s plan for stabilizing the financial system, recommending that the $700 billion Troubled Asset Relief Program be used to buy senior preferred stock of troubled institutions. He also gained attention in 2010 as the host of a single-year personal profit of nearly $5 billion, primarily in gold.

He has also been recognized for the consistent growth of his firm from a two-million-dollar startup in 1994 into a major New York hedge fund.
Career Highlights
Paulson’s first major breakthrough came in 2007, when he and his firm earned nearly $4 billion personally for him by shorting subprime mortgage-backed securities, a position he built carefully over the preceding years through credit default swaps. The next standout year was 2010, when he earned $4.9 billion, largely from gold-related investments, making him one of the highest-earning hedge fund managers in history. Most recently, in 2025, Forbes estimated his net worth at $3.8 billion, reflecting the lasting impact of those landmark trades.
Other Wins and Achievements
Beyond his trading record, John Paulson has built his reputation as a generous philanthropist. In June 2015, he donated $400 million to Harvard University’s School of Engineering and Applied Sciences, the largest single gift in the university’s history, and the school was renamed the Harvard John A. Paulson School of Engineering and Applied Sciences. In October 2012, he gave $100 million to the Central Park Conservancy, the largest monetary donation ever made to New York City’s park system, and in 2022 New York University named a new Washington Square building the John A. Paulson Center after a $100 million gift from him.
