Christmas could be very merry for someone after the next Mega Millions drawing. The jackpot is now over $320 million for the Christmas night drawing. The next drawing is Dec. 25 at 11 p.m. ET. There have been five jackpot wins so far in 2018. A single ticket was sold in South Carolina in October for the largest Mega Millions jackpot ever, $1.5 billion. But the winner of that prize has not yet claimed it. Mega Millions jackpots start out at $40 million and roll over if there is no jackpot winner. Tickets are sold in 44 states plus the District of Columbia and the U.S. Virgin Islands.
