Iowa Lottery officials say the ticket was sold at a Hy-Vee on Edgewood Road in Cedar Rapids. The person or people holding the ticket have yet to step forward to claim the prize from Wednesday's drawing.
The ticket matched the numbers of 7, 10, 14, 33 and 57, plus the Powerball number of 18.
Iowa Lottery Chief Executive Officer Terry Rich says lottery officials encourage jackpot winners to consult financial or legal advisers before claiming such a big prize.
If the ticket holder chooses to take a lump sum payout, the total is $160.3 million before taxes. After taxes, a little more than $112 million.
