Early Life and Education

Ken Griffin was born in Daytona Beach, Florida, and raised in Boca Raton. He showed an early aptitude for math and business, running a discount mail-order education software firm called EDCOM from his bedroom while in high school.

He attended Harvard University, where he launched his first hedge fund from his dorm room at Cabot House in 1987 at age 19. With $265,000 in capital raised from his grandmother, dentist, and others, he capitalized on the 1987 stock market crash. He graduated in 1989 with a degree in economics and immediately moved to Chicago to work with investor Frank Meyer, who provided the seed capital for Citadel.

Career

Griffin founded Citadel in 1990. The firm quickly became known for his intense culture and exceptional returns. In 2002, he established Citadel Securities, a market maker that uses computer algorithms to provide liquidity.

While Citadel suffered heavy losses during the 2008 financial crisis (losing 55%), Griffin successfully steered the firm back to profitability, preventing its collapse. In 2022, Citadel posted a record-breaking $16 billion in profit, the largest annual gain for a hedge fund in history, solidifying Griffin’s status as a Wall Street legend. He is a fierce advocate for free markets and has testified before Congress on market structure issues, including the GameStop trading frenzy in 2021.
