No one matched all six numbers and won the estimated $825 million grand prize in last night’s Powerball drawing. That means the next drawing Monday night will be for a massive $1 billion, according to a statement by Powerball.

The winning numbers Saturday night were: white balls 19, 31, 40, 46, 57, and the red power ball 23.

The increased jackpot will be the second-largest in U.S. history. The biggest prize was a $1.586 billion Powerball jackpot won by three ticket holders in 2016.

Although the advertised top prize will be an estimated $1 billion, that is for winners who receive their winnings through an annuity paid over 29 years. Winners almost always opt for cash, which for Monday’s drawing will be an estimated $497.3 million.

The $825 million jackpot for Saturday’s draw increased from $800 million on Friday as a result of strong ticket sales.
