Early Life
David Einhorn was born on November 20, 1968, in New Jersey and raised in Wisconsin after his family relocated in the mid-1970s. He attended Nicolet High School in Glendale, graduating in 1987.
He later attended Cornell University, where he earned a bachelor’s degree in government, graduating summa cum laude in 1991.
Early Career on Wall Street
After college, Einhorn began his career in investment banking, working at Donaldson, Lufkin & Jenrette before moving into hedge fund management at Siegler, Collery & Co.
These early roles helped him build a foundation in equity analysis and distressed investing, skills that would later define his approach at Greenlight Capital.
Founding Greenlight Capital
In 1996, Einhorn founded Greenlight Capital. The fund initially gained attention for its aggressive short-selling strategy, targeting companies that Einhorn believed were overvalued or fundamentally weak.
Greenlight’s reputation grew after several successful short positions, including bets against firms such as Conseco and Sirrom Capital. However, the fund also experienced volatility, including losses during the dot-com era.
Lehman Brothers
One of Einhorn’s most notable calls came in the lead-up to the 2008 financial crisis, when Greenlight Capital shorted shares of Lehman Brothers.
Einhorn publicly questioned Lehman’s accounting practices and exposure to risky real estate assets. Lehman ultimately collapsed in 2008, making the trade one of the most famous hedge fund calls of the era and cementing Einhorn’s reputation as a leading value investor.
Regulatory Scrutiny
In 2012, Einhorn and Greenlight Capital were fined by the UK Financial Services Authority over insider trading-related allegations, marking one of the most high-profile regulatory actions against the fund.
In the years that followed, Greenlight Capital faced performance challenges, with assets under management declining from roughly $12 billion in the mid-2010s to significantly lower levels later in the decade. Like many value-focused hedge funds, it struggled during prolonged periods of growth-stock dominance in global markets.
Apple Activism
Einhorn also became widely known for his activism in major corporations. In 2013, he filed a lawsuit against Apple Inc., pushing the company to distribute more of its large cash reserves to shareholders through preferred stock dividends.
The court ultimately ruled in his favor, and the case reinforced Einhorn’s reputation as a shareholder activist willing to challenge some of the world’s largest corporations.
Poker
Outside finance, Einhorn is also known for his success in professional poker tournaments. He competed in the World Series of Poker, finishing 18th in the 2006 Main Event, earning over $650,000.
In 2012, he achieved an even stronger result in the “Big One for One Drop” tournament, finishing third and winning more than $4.3 million, one of the largest poker payouts in history.
Philanthropy
Einhorn is actively involved in philanthropy, supporting several major charitable organizations. He has been a significant donor to the Michael J. Fox Foundation and serves on its board.
He is also involved with the Robin Hood Foundation, alongside other charitable contributions to education, healthcare, and public policy organizations.
Personal Life
David Einhorn was previously married to financial journalist Cheryl Strauss, with whom he has three children. The couple divorced in 2017.
He currently resides in Westchester County, New York, where he continues to manage investments and participate in public market commentary.
