Two winners will share America's biggest Powerball jackpot ever - 587.5 million US dollars (£366.4 million).
It is the second-largest top prize in US lottery history but mystery still surrounds the identity of the winners waking up to new lives as multimillionaires.
The numbers drawn are: 5, 16, 22, 23, 29. The Powerball is 6.
It was not clear whether the winning tickets belonged to individuals or groups.
Arizona lottery officials said they had no information on that state's winner or winners but would announce where it was sold during a news conference later in the day.
Lottery officials in Missouri were not immediately available for comment.
