The Powerball drawing on Saturday night was worth $590 million, and the lottery confirms there was one winner, with the ticket sold at a Zephyrhills, Florida Publix Supermarket.
The winning numbers are 10, 13, 14, 22, 52 with a Powerball number of 11.
It's the biggest jackpot ever for Powerball, the second largest lottery prize, after last year's MegaMillions super prize.
If you win, and elect to take the prize as cash, you'd get $376.9 million.
One reason the prize is so big, California has joined in the Powerball Lottery, bringing thousands more ticket sales.
Tickets are on sale until 9pm Saturday night.
