Kenneth Cordele Griffin is an American hedge fund manager. He is the founder and CEO of Citadel LLC, a Chicago-based investment firm. Citadel's group of hedge funds rank amongst the largest and most successful hedge funds in the world, and Griffin has earned several billion dollars during his tenure at the company. As of 2012, he has an estimated net worth of $3 billion. For several years, Griffin avoided extensive press coverage in a manner similar to other hedge fund managers such as billionaire Steven A. Cohen. As Citadel grew, he agreed that the firm would benefit from broader exposure and started opening up in 2001. More recently, Griffin has adopted a significantly more prominent media profile. He has appeared as the subject of a Bloomberg magazine cover story. He gave an interview to the New York Times in February 2014, publicizing a $150 million donation to his alma mater. In 2012 he opened up about his political views in an interview with the Chicago Tribune. With an estimated $14 billion in assets under management, Citadel remains one of the world's largest hedge funds.
