Stephanie McFarland, a spokeswoman for the Indiana Lottery, said the 180-day window has passed for whoever purchased the winning ticket at the Circle K store in Jeffersonville April 10 and the ticket is now worthless, CNN reported Wednesday.
"It is rare, but not unheard of, that a prize of such magnitude goes unclaimed," McFarland said.
McFarland said the largest unclaimed prize in the state was a $50 million Powerball jackpot that expired in 2002.
The unclaimed prize money is retained by the state.
