The Mega Millions jackpot has soared to an estimated $944 million for a drawing on Christmas Eve, marking the seventh-largest prize in the lottery’s history, though a lucky winner—facing one-in-302-million odds—would take home less than one-third of that amount after paying required taxes.

A Mega Millions player may win a big jackpot on Christmas Eve. The lottery prize for the December drawing is now at $1 billion.

The Mega Millions jackpot is expected 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.
