A single ticket sold in Michigan matched all five numbers and the red "Powerball" to win the $US320 million ($NZ397 million) Powerball lottery jackpot, the 10th largest prize in U.S. history.
The winning numbers drawn this week were 6, 27, 46, 51, 56 and the red Powerball, 21. The odds of having a winning ticket were one in 175 million, according to the lottery.
The largest U.S. jackpot was a $US656 million prize claimed in March by the owners of three winning tickets in the MegaMillions multi-state game.
The $US320 million Powerball prize was the fourth-largest in the history of the game, which is played in 42 states plus the District of Columbia and the Virgin Islands.
