Confidence rating:

Griffin's fortune is derived from the money he's made managing Citadel Advisors, the hedge fund firm he founded in 1990. It had $30 billion in assets under management as of August 2018, according to a company spokesperson.

Griffin probably has about $8 billion in personal assets in Citadel funds. This is based on a 2018 Form ADV filing, information on his holdings from those close to the firm who asked not to be identified because the information is private.

His sole ownership of Citadel's operating business is based on the hedge fund's 2018 brochure that indicates him as the only shareholder of the company's ultimate holding entity. It's valued using the price-to-AUM multiple of three publicly traded hedge funds: Och-Ziff, Janus Henderson and Man Group. Griffin's personal assets are deducted from this calculation and a 25% discount is applied to reflect 'key-man risk,' a common deduction to investment businesses that are largely dependent on a dominant individual investor.

Griffin also owns more than $600 million in personal real estate, including in oceanfront property in Palm Beach, Florida, and condominium units in Manhattan and Chicago and an historic London mansion. They're valued at their purchase prices as detailed in Bloomberg News and The Real Deal, a real estate publication.

Griffin declined to comment on his net worth through a spokesman in December 2017.

Biography

Birthdate: 10/15/1968
Family: Divorced, No children
Education: Harvard University

Kenneth Cordele Griffin was born and raised in Florida, according to a 2011 profile of him in Chicago Magazine. He attended Harvard University where he majored in economics, graduating in 1989 after three years.

With a computer, fax machine and telephone, he began trading convertible bonds in 1987 out of his dorm room with $265,000 he raised from his mother, grandmother and two non-family investors, according to Bloomberg Markets magazine. He persuaded his dorm's janitor to let him place a satellite dish on the rooftop to get access to real-time information.

After Harvard, Griffin moved to Chicago to work for Glenwood Capital founder Frank Meyer. He opened his hedge fund -- its original name was Wellington -- with $4.6 million the next year. He changed the firm's name to Citadel, and over the next decade and a half, the company delivered an annualized return of more than 25 percent.

The billionaire personally stopped trading by 2005, telling Bloomberg Markets magazine that his staff was better at it than he was. The funds lost $9 billion in the 2008 financial crisis, a period during which he told Bloomberg News he gained 20 pounds. Citadel's funds recovered all of their losses by January 2012, according to Citadel's website.

Griffin is an active art collector, paying $60.5 million for Paul Cezanne's "Curtain, Jug and Fruit Bowl" in 1999, then a record price for an Impressionist painting. He bought Jasper Johns's "False Start" painting for $80 million in 2006 from music mogul David Geffen.

Griffin has given more than $600 million to a number of non-profit organizations including the University of Chicago, Ann & Robert Lurie Children's Hospital and the American Museum of Natural History. His $150 million donation to Harvard for student aid was the largest-ever gift to school at the time.

Griffin's marriage to Anne Dias ended in 2014. They have three children.
