A Powerball jackpot is expected to be at least $1.7 billion for a Christmas Eve drawing, which would make it one of the largest in US lottery history. It is unclear if someone has already won the jackpot, as some outlets suggest a winner, while others indicate the drawing has not yet occurred. The jackpot has been growing, with some notable wins reported, including a $1 million ticket sold in Ohio and two winning tickets sold in New York.
