Harrah's Entertainment shareholders approved a 17.1 billion dollar buyout by two private equity groups.
Company officials say the deal approved this afternoon is the largest ever to take a publicly held casino company private.
Shareholders controlling 66 percent of outstanding stock approved selling the world's largest casino company to Apollo Management Group and Texas Pacific Group.
Harrah's Las Vegas-based board had unanimously backed the deal.
It still requires approval from gambling regulators in more than a dozen states and several tribal nations where Harrah's operates.
Harrah's operates 39 casinos, including Caesars and Harrah's in Atlantic City.
