A single winning ticket for a Mega Millions lottery jackpot of $1.337 billion, the second-largest in US history, was sold in Illinois, lottery organizers said on Saturday.
"Congratulations to the Illinois Lottery for selling the winning ticket for the $1.28 billion Mega Millions jackpot," Ohio Lottery Director Pat McDonald said in a statement.
"We're eager to find out who won and look forward to congratulating the winner soon!"
The ticket was sold at the Speedway fuel and convenience store on East Touhy Avenue in Des Plaines, Illinois, a Chicago suburb. Going into the draw on Friday night, the jackpot was estimated at $1.28 billion, but swelled as people piled in to try their luck.
The still-to-be-identified holder of the winning ticket, which would have cost $2 to buy, matched all six numbers. They have the choice of a lump-sum payment of $780.5 million or an annual payout over 30 years.
Most winners go for the lump sum, which comes with a hefty tax bill, according to the Mega Millions website.
The winning numbers for the jackpot, which had been rolling since it was last won at $20 million in Tennessee on 15 April, were 13, 36, 45, 57 and 67, plus the mega ball 14.
It is the second largest jackpot in the 20-year history of the game, topped only by the $1.537 billion won in South Carolina in October 2018.
The latest Mega Millions lottery was held in 45 states, Washington, DC, and the US Virgin Islands.
Half of the proceeds from the sale of each Mega Millions ticket remains in the state where the ticket was sold; the money supports lottery beneficiaries, such as education or public employee pensions, and retailer commissions.
"This exciting jackpot run has had a significant positive impact on the revenues for good causes raised by our member lotteries," said Ohio lottery chief McDonald, who is the lead director for the Mega Millions Consortium.
Retailers get a 1.0% selling bonus for the winning ticket, capped at $500,000, according to Harold Mays, director of the Illinois Department of the Lottery.
