Kenneth Cordele Griffin is the founder and CEO of Citadel LLC, one of the world's most successful multi-strategy hedge funds, and Citadel Securities, one of the largest market makers globally. Founded in 1990 from his Harvard dorm room, Citadel has grown to manage approximately $65 billion in assets.
Griffin began trading convertible bonds from his dormitory at Harvard University, reportedly installing a satellite dish on the roof to get real-time market data. After graduating in 1989, he launched what would become Citadel with $4.6 million from investors. The firm survived the 2008 financial crisis — when it lost 55% — and rebuilt to become arguably the most dominant multi-strategy platform in the industry.
Under Griffin's leadership, Citadel has generated over $74 billion in net gains for investors since inception, making it one of the most profitable hedge funds in history. Griffin is also known for his record-breaking real estate purchases, including a $238 million New York penthouse, and his extensive art collection. Forbes estimates his net worth at approximately $43 billion, making him the wealthiest hedge fund manager in the world.
