The ticket had the winning numbers of 22, 10, 13, 14, 52 and Powerball number 11, said David Bishop, deputy secretary of Florida Lottery.
Saturday's jackpot was the largest in Powerball history, surpassing a $587.6 million jackpot split in November by winners in Arizona and Missouri, CNN reported Sunday.
The largest lottery jackpot in U.S. history was the March 2012 Mega Millions game worth $656 million.
Had there been no winner in Saturday's Powerball game, the jackpot would have skyrocketed to a record $925 million for Wednesday's drawing, CNN said.
The odds of winning the jackpot were 1 in 175,223,510, which is less likely to happen than hitting two consecutive holes in one.
