Hang onto those stocking-stuffer lottery tickets. The Mega Millions jackpot has surpassed $1 billion after no ticket matched all six numbers drawn on Christmas Eve.

“We know that many people will likely receive tickets to Friday’s drawing as holiday gifts, and what a gift that would turn out to be if you ended up with a ticket worth a $1.15 billion jackpot,” Lead director for the Mega Millions Consortium Joshua Johnston said.

The Mega Millions jackpot is estimated to hit $1 billion on Christmas Eve after there was no winner declared last week. The estimated cash prize is now $448.8 million, according to the Mega Millions lottery. Another drawing will happen at 11 p.m. on Tuesday. All drawings are finalized at 10:45 p.m.
