27. Illinois : Ken Griffin
Ken Griffin’s hedge fund firm, Citadel LLC, continues to perform very well. The firm’s main hedge funds returned nearly 18% net of fees in 2014. Griffin, who began trading in the 1980s in his Harvard dorm room, founded Citadel in 1990 with approximately $4 million. The firm now manages some $24 billion in assets.
Griffin filed for divorce in 2014 from his wife of 11 years, Anne Dias Griffin, a Goldman Sachs alum who is also a money manager. The divorce proceedings in Illinois state court have been contentious, with Dias Griffin complaining in a court filing that her estranged husband is being stingy with child care payments while cutting off her free reign of their Chicago high rise apartment. Griffin sees things differently and has said he is fully supporting his young children and has balked only at what he deems to be excessive monetary requests from Dias Griffin.
