Template:Infobox person

John Alfred Paulson (born December 14, 1955) is an American billionaire hedge fund manager, investor, and philanthropist who is best known for what has been called "the greatest trade ever"—his massively profitable bet against the U.S. subprime mortgage market during the 2007–2008 financial crisis. By shorting mortgage-backed securities through credit default swaps, Paulson personally earned approximately $4 billion in 2007 alone, while his firm Paulson & Co. generated profits exceeding $15 billion for its investors.

Paulson founded Paulson & Co. in 1994 with just $2 million in capital and one employee. At its peak in 2011, the firm managed approximately $38 billion in assets, making it one of the largest hedge funds in the world. However, after years of losses following his historic 2007-2008 success, Paulson converted the firm into a family office in 2020 to manage primarily his own wealth.

Beyond his investment career, Paulson has emerged as one of America's most significant philanthropists, donating $400 million to Harvard University—the largest gift in the university's history—and $100 million to the Central Park Conservancy. He has also been a major political donor, raising over $50 million for Donald Trump's 2024 presidential campaign and was briefly considered for the position of United States Secretary of the Treasury.

Early life and background

Family origins

John Alfred Paulson was born on December 14, 1955, in Queens, New York City, the third of four children born to Alfred G. Paulson (1924–2002) and Jacqueline Boklan Paulson (1926–2018).

His father, Alfred Guillermo Paulson, was born in Ecuador to a father of mixed French and Norwegian descent and an Ecuadorian mother. Alfred Paulson immigrated to the United States and built a career in business, eventually establishing himself in New York's middle class.

His mother, Jacqueline Boklan, was the daughter of Jewish immigrants from Lithuania and Romania who had settled in New York City. This diverse heritage—part Latino, part European, part Jewish—gave Paulson a multicultural background unusual for his generation.

Childhood in Queens

Young John grew up in Le Havre, a substantial apartment complex in Queens comprising thirty-two buildings, 1,021 apartments, and twenty-seven acres of land. The development featured amenities including two swimming pools, a clubhouse, a gym, and three tennis courts—facilities that suggested a comfortable, if not wealthy, middle-class existence.

The Paulson family later moved to a modest home in Beechhurst, Queens, where John continued his education in local public schools. He was identified early as academically gifted and placed in programs for advanced students. By eighth grade, Paulson was already studying calculus, Shakespeare, and other high school–level subjects—a precocious start that foreshadowed his later academic achievements.

Early entrepreneurial instincts

Paulson's business instincts emerged remarkably early. At just six years old, he started his first entrepreneurial venture, selling Charms candies on the playground in his Queens neighborhood. He purchased the candies in bulk, sold each piece at a profit, and carefully saved his earnings in a treasure chest.

This childhood enterprise contained the seeds of his later success: identifying opportunities, understanding margins, and maintaining the discipline to accumulate capital rather than spend it immediately. These lessons, learned on a Queens playground, would eventually be applied to trades measured in billions of dollars.

Education

New York University

In 1973, Paulson enrolled at New York University, initially pursuing a degree in philosophy. The choice reflected intellectual curiosity rather than career calculation—philosophy seemed far removed from the world of high finance that would later define his life.

After his first year of college, Paulson took an unconventional detour. He traveled to Ecuador, his father's birthplace, and attempted to establish several businesses there. His most notable venture involved exporting children's clothing to department stores back in New York. However, the business proved insufficiently profitable, and Paulson returned to NYU to complete his studies—now with a more practical focus.

Switching his major to finance, Paulson excelled academically. In 1978, he graduated as valedictorian of his class from NYU's College of Business and Public Administration (now the Stern School of Business), earning his degree summa cum laude. This academic achievement marked him as exceptional even among a competitive cohort.

Harvard Business School

Following his triumph at NYU, Paulson was accepted to Harvard Business School, where he attended on a prestigious Sidney J. Weinberg/Goldman Sachs scholarship. The scholarship was named for Goldman's legendary leader and signaled that Paulson was seen as one of the most promising young business talents in the country.

At Harvard, Paulson continued to excel. He earned his MBA in 1980 as a George F. Baker Scholar, a distinction reserved for the top five percent of each class. The Baker Scholar designation is Harvard Business School's highest academic honor, and recipients are virtually guaranteed successful careers in business and finance.

These credentials—valedictorian at NYU, Baker Scholar at Harvard—established Paulson's intellectual bona fides in an industry that would later question whether his success was luck or skill.

Early career

Boston Consulting Group (1980)

Paulson began his professional career in 1980 at the Boston Consulting Group, the elite management consulting firm. At BCG, he conducted research and provided strategic advice to corporate clients, gaining exposure to how businesses operated across various industries.

However, Paulson quickly realized that consulting was not his calling. He was ambitious to work directly in investment on Wall Street, where he could apply his analytical skills to making money rather than advising others on how to do so.

Odyssey Partners

Leaving BCG, Paulson joined Odyssey Partners, a New York investment firm where he worked under the tutelage of Leon Levy, one of the pioneers of the hedge fund industry. Levy, who had co-founded the Oppenheimer Funds and later created Odyssey, was known for his sophisticated investment strategies and rigorous analytical approach.

Working with Levy gave Paulson his first real exposure to professional money management. He learned how institutional investors think about risk, return, and the construction of investment portfolios.

Bear Stearns

Paulson next moved to Bear Stearns, where he joined the mergers and acquisitions department. M&A work in the 1980s was an intensely competitive field, dominated by the dealmaking culture that characterized the era's leveraged buyout boom.

At Bear Stearns, Paulson developed expertise in analyzing corporate transactions, valuing businesses, and understanding the financial structures that made deals work. This knowledge would prove valuable later when he began analyzing complex structured finance products like the mortgage-backed securities he would eventually short.

Gruss Partners

From Bear Stearns, Paulson moved to Gruss Partners LP, a merger arbitrage–focused hedge fund, where he became a general partner. Merger arbitrage involves investing in companies that are targets of announced acquisitions, profiting from the spread between the current stock price and the acquisition price.

This strategy requires deep analytical skills, patience, and the ability to assess risk accurately—qualities that Paulson would later apply to his subprime mortgage trades. At Gruss, he honed his understanding of how to construct positions that could profit from specific events while managing downside risk.

Paulson & Co.

Founding (1994)

In 1994, Paulson took the leap that would define his career: he founded Paulson & Co., his own hedge fund, with just $2 million in capital and a single employee. The firm was headquartered in New York City and initially focused on merger arbitrage, the strategy Paulson had mastered at Gruss Partners.

The early years were challenging. Running a small hedge fund with limited capital required Paulson to generate consistent returns to attract new investors. He built his reputation slowly, delivering steady if unspectacular performance through the late 1990s and early 2000s.

Growth and strategy evolution

Through disciplined execution and careful risk management, Paulson & Co. grew steadily. The firm expanded beyond pure merger arbitrage into other event-driven strategies, looking for opportunities created by corporate actions, regulatory changes, or market dislocations.

By the mid-2000s, Paulson & Co. had accumulated several billion dollars in assets under management—a respectable sum, but still far from the industry's giants. Paulson himself was successful but hardly a household name in finance. That was about to change dramatically.

The greatest trade ever (2007-2008)

Identifying the housing bubble

In 2005 and 2006, Paulson and his team began to scrutinize the U.S. housing market with increasing concern. What they found alarmed them: home prices had risen to unprecedented levels relative to incomes and rents, mortgage lending standards had collapsed, and an enormous quantity of subprime mortgages had been originated to borrowers who were unlikely to repay them.

The subprime mortgage crisis that would eventually devastate the global economy was, in Paulson's analysis, not merely possible but inevitable. The only question was timing.

What made Paulson's insight valuable was not that he predicted housing prices would fall—many observers shared this concern—but that he identified a mechanism to profit massively from this prediction with limited downside risk.

The credit default swap strategy

Paulson's genius lay in his use of credit default swaps (CDS) to bet against mortgage-backed securities. A credit default swap is essentially insurance against a bond default. The buyer of a CDS pays a small premium periodically; in return, if the underlying bond defaults, the seller must pay the buyer the full face value.

By purchasing credit default swaps on mortgage-backed securities stuffed with subprime loans, Paulson created a trade with an asymmetric payoff: if housing prices continued rising or stayed flat, he would lose only the premiums paid for the CDS. But if the mortgages began defaulting, his CDS positions would pay off spectacularly.

This was not gambling—it was a calculated bet based on rigorous analysis. Paulson and his team had studied the underlying mortgage pools in detail, identifying the securities most likely to fail.

The trade unfolds

In 2007, the housing market began to crack. Subprime mortgage defaults spiked, mortgage-backed securities plummeted in value, and Paulson's credit default swaps soared. The 2007–2008 financial crisis was underway, and Paulson & Co. was positioned perfectly.

The scale of the profits was staggering. In 2007 alone, Paulson & Co. earned approximately $15 billion for its investors. Paulson personally earned nearly $4 billion—at the time, the largest single-year payout in Wall Street history.

The trade continued to generate profits into 2008 as the crisis deepened. By the time the dust settled, Paulson had transformed "from an obscure money manager into a financial legend," as one account put it. His bet against subprime mortgages is frequently described as "the greatest trade ever."

Recognition and fame

The subprime short brought Paulson instant fame. He was profiled extensively in the financial press and became the subject of The Greatest Trade Ever, a 2009 book by journalist Gregory Zuckerman that detailed how Paulson identified and executed the trade.

His success also featured prominently in The Big Short, Michael Lewis's bestselling account of the financial crisis, and the subsequent film adaptation. While Paulson was not the main character in Lewis's narrative (which focused on other investors like Michael Burry), his trade was acknowledged as among the most successful.

ABACUS and Goldman Sachs controversy

Paulson's role in the financial crisis was not without controversy. In April 2010, the SEC filed a civil lawsuit against Goldman Sachs over Abacus 2007-AC1, a synthetic CDO that Goldman had created with Paulson's involvement.

The SEC alleged that Goldman had misrepresented who assembled the mortgage package underlying the CDO. Specifically, Goldman allegedly failed to disclose that Paulson—who planned to bet against the CDO—had helped select the mortgages that went into it. Investors who bought the CDO, not knowing Paulson's role, lost approximately $1 billion.

Paulson & Co. was not named as a defendant and maintained it had made no misrepresentations. In a statement, the firm noted it "was not the subject of this complaint, made no misrepresentations and is not the subject of any charges." Goldman Sachs ultimately paid $550 million to settle the charges—at the time, the largest settlement in SEC history.

In 2011, ACA Financial Guaranty filed a separate lawsuit against Paulson, claiming that Goldman Sachs and Paulson had "deceived ACA into believing Paulson" was aligned with their interests, when in fact he was betting against the securities. This case contributed to ongoing debate about the ethics of Paulson's trades.

Post-crisis performance

2010: Another banner year

Following his triumph, Paulson continued to generate strong returns. In 2010, he personally earned $4.9 billion, cementing his status as one of the most successful hedge fund managers in history. His firm's assets under management swelled as investors rushed to participate in his subsequent trades.

Gold bet and 2011 losses

In November 2009, Paulson announced a new gold fund focused on gold mining stocks and gold-related investments. His thesis was that massive monetary expansion by central banks in response to the financial crisis would eventually produce inflation, making gold an attractive hedge.

"We view gold as a currency, not a commodity," Paulson explained. "Its importance as a currency will continue to increase as the major central banks around the world continue to print money."

The gold bet initially worked well—Paulson reportedly earned approximately $5 billion on gold positions in 2010. However, 2011 proved disastrous.

In 2011, Paulson & Co. was ranked as the world's fourth-largest hedge fund with $36 billion in assets under management. But during that year, his flagship Advantage fund lost 36% and Advantage Plus lost a staggering 52%.

The losses came from multiple directions. Paulson had made substantial investments in Bank of America and Citigroup, expecting financial stocks to recover. Both declined sharply. More embarrassingly, he had invested heavily in Sino-Forest Corporation, a China-based, Canadian-listed company that was later revealed to be a fraud. When Sino-Forest's stock collapsed amid fraud allegations, Paulson's funds suffered significant losses.

Even his gold hedge failed to protect him: gold prices fell 11% in September 2011 alone.

Persistent underperformance

The 2011 debacle was not an aberration but the beginning of a prolonged period of underperformance. Investors who had flooded into Paulson & Co. after the subprime triumph began redeeming their capital.

Assets under management declined from a peak of approximately $38 billion in 2011 to about $9 billion by 2019. The firm that had produced one of history's greatest trades struggled to generate consistent returns.

Some observers suggested that Paulson's subprime success may have been a one-time feat that could not be repeated. Others noted that his concentrated, high-conviction approach—which produced outsized gains when he was right—generated outsized losses when he was wrong.

Conversion to family office (2020)

In 2020, Paulson announced that Paulson & Co. would convert from a hedge fund to a family office, returning outside capital and managing primarily his own money. The decision reflected the reality that after years of losses, he was already managing mostly his own capital.

"Paulson turned his hedge fund firm into a family office in 2020 after assets dropped to about $9 billion the previous year from a peak of $38 billion in 2011 and he found himself managing mostly his own money," one account noted.

The conversion allowed Paulson to invest without the pressure of quarterly performance reporting to outside investors. It also reduced regulatory requirements and administrative burdens.

Recent investments

Gold mining and Perpetua Resources

Despite his mixed track record with gold after 2011, Paulson has remained committed to precious metals investments. As of 2024, he owns approximately 40% of Perpetua Resources Corp., a gold mining company whose shares jumped 104% in 2024 as gold prices rallied to record highs.

Perpetua Resources represents one of several large positions that recorded double-digit gains in 2024, contributing to a partial recovery in Paulson's wealth.

Trump administration windfall

Paulson's investment in Perpetua Resources received a significant boost from the Trump administration. In 2025, Trump approved a mining road that delivered an estimated $70 million windfall to the company, benefiting Paulson as its largest shareholder.

This decision attracted criticism from those who noted Paulson's role as a major Trump donor, raising questions about potential conflicts of interest.

Personal life

Marriage to Jenny Zaharia

In 2000, Paulson married Jenny (Jenica) Zaharia in an Episcopalian ceremony in Southampton, New York. Jenny was a Romanian immigrant who had come to the United States after her brother George, a track star in Romania, defected and moved to Queens.

Before their marriage, Jenny had worked for Paulson as his assistant. The couple's relationship reportedly developed from their professional association.

Children and family residences

John and Jenny Paulson have two daughters: Giselle and Danielle, born in the 2000s. The family lived primarily in a 28,500-square-foot townhouse on the Upper East Side of Manhattan, on East 86th Street, which Paulson purchased in 2004 for $14.7 million.

The family also maintained homes in Aspen, Colorado, purchased for $24.5 million in 2010, and an estate in Southampton, New York, acquired for $41 million in 2008. These properties reflected the lifestyle afforded by Paulson's billions.

Puerto Rico interests

Beginning around 2014, Paulson developed significant interests in Puerto Rico. At the 2014 Puerto Rico Investment Summit, he declared: "Puerto Rico will become the Singapore of the Caribbean."

Paulson invested in the territory's municipal debt and real estate developments, and began building a home at a resort. He also reportedly led efforts to convince other wealthy Americans to relocate to Puerto Rico to take advantage of favorable tax treatment.

These activities later became controversial in his divorce proceedings, with allegations that Paulson had used Puerto Rico structures to hide assets.

In September 2021, Paulson filed for divorce from Jenny after more than 20 years of marriage. The couple did not have a prenuptial agreement, potentially exposing Paulson's fortune to substantial division.

The divorce quickly became contentious. In 2022, Jenny sued Paulson for $1 billion in damages, alleging that he had hidden billions of dollars in secret trusts created for her, their daughters, and other family members without her knowledge.

Particularly controversial was an allegation involving a luxury penthouse apartment at the St. Regis Bahia Beach Resort in Puerto Rico. Jenny claimed that Paulson had agreed in 2020 to buy the apartment from a 2009 family trust for an artificially low price of $5.6 million, when the property was actually worth approximately $15 million.

As of 2024, Paulson was reportedly engaged to Alina de Almeida, a 35-year-old clinical dietitian.

Political activities

Trump fundraising

Paulson has been a major political donor, particularly to Republican candidates and causes. He has been a supporter of Donald Trump since Trump's first presidential campaign in 2016, serving as one of Trump's economic advisors during that race.

His support intensified during the 2024 presidential campaign. On April 6, 2024, Paulson hosted a fundraiser for Trump at his Palm Beach home that raised $50.5 million—reportedly the largest single political fundraiser in American history. Individual tickets for the event ranged from $250,000 to $814,600.

Over the course of Trump's campaigns, Paulson has raised more than $40 million for the former president.

Treasury Secretary consideration

Following Trump's victory in the 2024 presidential election, Paulson was reportedly considered for the position of United States Secretary of the Treasury. Trump had publicly called Paulson a "money machine," and the appointment would have placed one of Wall Street's most famous investors in charge of the nation's finances.

However, in November 2024, Paulson removed himself from consideration. "My complex financial obligations would prevent me from holding an official position in President Trump's administration at this time," he stated. Becoming Treasury Secretary would have required divesting numerous holdings, including his substantial stake in mining companies.

Scott Bessent was ultimately nominated for the position instead.

Criticism of Democratic policies

During the 2024 campaign, Paulson was publicly critical of Kamala Harris's economic proposals, particularly a proposed 25% tax on unrealized capital gains.

"If they do implement a 25% tax on unrealized gains, that would cause mass selling of almost everything—stocks, bonds, homes, art," Paulson told Fox News. He reportedly threatened to pull his money from the market if Harris won the election.

Continued political involvement

After Trump took office, Paulson continued supporting Trump's political priorities. In June 2025, for example, he donated $250,000 to MAGA KY, a super PAC targeting Congressman Thomas Massie (R-KY).

Philanthropy

Harvard University: Largest gift in history

In June 2015, Paulson made the largest gift in Harvard University's nearly 400-year history: a $400 million endowment to support the School of Engineering and Applied Sciences.

To honor his generosity, the school was renamed the Harvard John A. Paulson School of Engineering and Applied Sciences. The gift provides permanent funding for faculty development, research, scholarships, and financial aid.

"There is nothing more important to improve humanity than education," Paulson stated in announcing the gift. He emphasized his belief that engineering and applied sciences would be critical to solving the world's most pressing challenges.

The donation reflected Paulson's connection to Harvard, where he had earned his MBA as a Baker Scholar, and his belief in the power of elite education to drive innovation.

Central Park Conservancy

In October 2012, Paulson donated $100 million to the Central Park Conservancy, the nonprofit organization that maintains Central Park. At the time, this represented the largest monetary donation in the history of New York City's park system.

"The park where he bikes and jogs almost every day is fundamental to the economic and cultural health of New York City," Paulson said in announcing the gift. The donation supported maintenance, restoration, and programming in the iconic urban green space.

New York University

Paulson has maintained strong ties to his undergraduate alma mater. In 2022, he donated $100 million to New York University, further cementing his status as one of the university's most generous alumni.

Other philanthropic activities

Beyond his landmark gifts, Paulson has supported numerous other causes:

Board memberships

Paulson serves on numerous nonprofit boards, including:

  • Harvard Business School Board of Dean's Advisors
  • New York University Board of Trustees
  • Central Park Conservancy
  • Metropolitan Museum of Art
  • Council on Foreign Relations
  • 92nd Street Y

Net worth

Paulson's net worth has fluctuated substantially over his career, reaching as high as $13.8 billion in 2014 before declining significantly.

As of 2025, estimates vary:

  • Forbes estimated his net worth at $3.8 billion as of August 2025
  • The Bloomberg Billionaires Index reported $5.8 billion
  • Some sources estimate approximately $6 billion when adjusted for various factors

The decline from his peak reflects both investment losses following his 2007-2008 triumph and the extended divorce proceedings with Jenny Paulson, which may result in significant asset division.

Despite the reduction from his peak wealth, Paulson remains among the wealthiest hedge fund managers in history and one of America's billionaires.

Legacy and assessment

The greatest trade

Paulson's place in financial history is secured by his 2007-2008 subprime short. The trade demonstrated that rigorous analysis combined with the right financial instruments could generate enormous profits from identifying and betting against market bubbles.

Whether the trade represented skill or luck—or some combination—remains debated. Supporters point to the depth of Paulson's analysis and the precision of his positioning. Critics note that many aspects of the trade required fortuitous timing and that Paulson has been unable to repeat the success.

Subsequent performance

The years following Paulson's greatest triumph have been challenging. His funds suffered substantial losses in 2011 and subsequent years, and the conversion to a family office in 2020 effectively acknowledged that outside investors had lost confidence.

This pattern—spectacular success followed by persistent underperformance—has led some to question whether Paulson's subprime bet was a one-time achievement rather than evidence of repeatable investment skill.

Philanthropy and public life

Beyond investing, Paulson has established a significant philanthropic legacy. His $400 million gift to Harvard is among the largest educational donations in American history, while his Central Park gift helped secure the future of New York's most famous public space.

His political activities have been more controversial, with critics questioning the relationship between his campaign donations and subsequent policy decisions that benefited his investments.

Influence on the industry

Paulson's subprime trade influenced how hedge funds and other institutional investors approach potential market dislocations. The success demonstrated that patient, conviction-based investing could generate outsized returns—but also highlighted the difficulty of consistently identifying such opportunities.

Investment philosophy

Concentrated, high-conviction approach

Paulson has historically employed a concentrated investment approach, taking large positions in a relatively small number of ideas. This strategy amplifies returns when correct but also magnifies losses when wrong—as demonstrated by both his subprime triumph and subsequent gold and banking losses.

Focus on asymmetric payoffs

The subprime trade exemplified Paulson's preference for positions with asymmetric risk-reward profiles. By using credit default swaps, he limited potential losses to the premiums paid while retaining unlimited upside if his thesis proved correct.

Event-driven and catalyst-focused

Throughout his career, Paulson has favored event-driven strategies that identify specific catalysts likely to move prices. Whether in merger arbitrage, the housing market, or gold, he has sought situations where particular events would cause assets to be repriced.
