The record Powerball jackpot now stands at $550 million after officials say sales keep driving up the payout amount.
The jackpot was boosted to $500 million on Tuesday and raised again Wednesday morning to $550 million.
A winner taking the cash option would get $360.2 million before taxes.
The numbers are an estimate and could be increased again as the drawing nears.
Powerball officials say they now believe there is a 75 percent chance that the winning combination of numbers will be drawn Wednesday night.
