Here's what financial advisors suggest players do if they hit the $748 million jackpot. A Powerball jackpot of $748 million is up for grabs ahead of tonight's drawing. It has a cash value of $325.1 million and is the largest Powerball jackpot since a $1.817 billion prize was won in Arkansas on Christmas Eve. The jackpot was last won in May by two players, one in Florida and one in Texas, who split the $20 million prize, according to Powerball. Steve Azoury, owner of Azoury Financial in Troy, Michigan, advised winning players to hire a tax attorney, a tax accountant and a financial advisor.
