The Powerball lottery jackpot — the biggest of the year — is swelling after nobody won in Monday night's drawing. The jackpot is now $643 million, with the next drawing set for Wednesday night. Although no one took home the full prize, two Powerball players won $1 million each, according to Powerball.

The Powerball winning numbers are in for the Monday, Aug. 18 drawing with a jackpot that increases to $605 million ($273.4 million cash value). The largest winning Powerball jackpot ticket sold in Michigan was worth $842.

No one hit the jackpot in the Monday, Aug. 18 drawing, so the grand prize will increase to an estimated $643 million.
