The winning ticket for the $425 million Powerball jackpot was sold at a California gas station, but there was no immediate word on who may have won one of the largest lottery jackpots in U.S. history.
Wednesday night's winning numbers were: 1, 17, 35, 49, 54 and a Powerball of 34.
California lottery officials said the ticket was sold at Dixon Landing Chevron in Milpitas, about 10 miles north of San Jose. The business will receive $1 million for selling the winning ticket.
Chevron employee Rajwinder Singh said he probably sold the winning ticket.
"I've been here working from 8 a.m. to 8 p.m.," he said. "I hope I'll find out soon."
The store was a buzzing with activity since word began to spread.
"We're getting telephone calls," said employee Bipin Sangh at the 24-hour station.
The prize has been growing bigger and bigger since December.
The jackpot jumped to $400 million over the weekend after there were no winning tickets sold in Saturday's drawing for $330 million.
The biggest ever Powerball prize was $590 million before taxes, won by a woman in Florida in May 2013. The highest lottery jackpot ever was shared by three tickets in Kansas, Illinois and Maryland in March 2012 for a Mega Millions jackpot totaling $656 million.
Powerball is played in 43 states, Washington, D.C., and the U.S. Virgin Islands. The odds of winning are one in 175 million, according to the association.
The Multi-State Lottery Association is a non-profit based in Urbandale, Iowa, owned and operated by member lotteries.
