January 19, 2021 It would seem that billionaire American businessman Dan Gilbert (pictured) has quietly exited the casino business after reportedly selling off his remaining stake in operator Jack Entertainment to members of the firm’s management team. According to a Monday report from the Cleveland Scene newspaper, Gilbert is worth an estimated $34 billion thanks to his Quicken Loans Incorporated mortgage lending business and established Detroit-headquartered Jack Entertainment in 2009 after helping to back a ballot measure that legalized casino gambling in Ohio. The operator subsequently went on to hold interests in six gambling-friendly venues including the Greektown Casino Hotel, Jack Cleveland Casino, Jack Cincinnati Casino and Jack Thistledown Racino.
