The $768.4 million is the third-largest behind the world record $1.586 billion Powerball jackpot shared by winners in California, Florida and Tennessee in January 2016, and the $1.537 billion Mega Millions jackpot won in South Carolina last October.
Seven tickets matched all five white balls, but missed matching the red Powerball in Wednesday's drawing to win a $1 million prize. Those tickets were sold in New York, New Jersey, Arizona, Indiana, Missouri and two in California.
Two other tickets, sold in Kansas and Minnesota, matched all five white balls and doubled the prize to $2 million, because the tickets included the Power Play option for an additional $1.
The last big Powerball win was back on December 26, 2018, when a truck driver from Brooklyn took home the $298.3 million prize.
His win marked the second consecutive Powerball jackpot win by a New Yorker, and third of the last four.
