NEW BERLIN, Wis. (AP) — A single ticket that matched all six Powerball numbers to win the estimated $768.4 million jackpot — the third-largest jackpot in U.S. lottery history — was sold in a Milwaukee suburb, Wisconsin Lottery officials said early Thursday.

The ticket, worth a cash option of $477 million, was sold in New Berlin, a city of about 40,000 people roughly 14 miles southwest of Milwaukee.

Lottery officials scheduled a news conference for Thursday morning, but said the winner or winners have yet to come forward. The retailer that sold the ticket wasn’t immediately identified but will receive a $100,000 payout for selling the winning ticket for Wednesday night’s drawing.

Under Wisconsin law, the winner or winners can’t remain anonymous and have 180 days to claim the prize, otherwise the ticket is worthless.

The win comes almost exactly two years after Wisconsin hit its last Powerball jackpot, when a Milwaukee resident won $156.2 million on March 22, 2017.

The winning numbers are 16, 20, 37, 44 and 62. The Powerball number is 12. Powerball lists the odds for winning the grand prize as 1 in 292,201,338.00.

The latest jackpot 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.

“It’s going to be a very green spring for our first Powerball jackpot winner of 2019,” David Barden, Powerball Product Group chairman and New Mexico Lottery CEO, said in a statement. “A jackpot of this size can make many dreams come true – not just for the winner, but for all Lottery beneficiaries and the lucky state of Wisconsin.”

Although the prize grew steadily since the previous jackpot winner on Dec. 26, the odds of matching the five white balls and single Powerball remained a dismal 1 in 292.2 million.

The $768.4 million estimated figure refers to the annuity option, paid over 29 years. Nearly all grand prize winners opt for the cash prize, which for Wednesday’s drawing would be an estimated $477 million. Both prize options are before taxes.

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 Arizona, two in California, Indiana, Missouri, New Jersey and New York. 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.

Powerball is played in 44 states, plus Washington, D.C., the U.S Virgin Islands and Puerto Rico.
