Just one more $75 million jump is needed - the same boost the jackpot has now seen since no one won Wednesday's $250 million prize.
Two days ago.
Powerball has now gone up $125 million in a single week.
Apparently, raising the price to $2 a ticket on Jan. 15 hasn't hurt the dollar haul.
The $325 million jackpot, payable in 30 yearly payments, is the ninth biggest for any U.S. lottery.
The record for any U.S. annuity jackpot was $390 million, set in March 2007 by Mega Millions. A Cape May County, N.J., couple and a Georgia trucker split the cash: $233.1 million.
Only one drawing ever paid more cash: Mega Millions paid out $240 million (less taxes) to two winners, in Idaho and Washington State, who hit on Jan. 4, 2011. That drawing had the second biggest annuity ever, $380 million.
Powerball's biggest annuity ever, $365 million, won in February 2006 by food-plant workers in Nebraska, set the all-time record for a win by a single ticket.
But the cash the winners collected - $177 million - is no longer Powerball's high mark.
Forty-one states, including Pennsylvania, New Jersey and Delaware, offer both Powerball and Mega Millions.
