Mega Millions jackpot could top $2B if there's no winner

The largest jackpot in U.S. lottery history could be decided Tuesday night.

Up for grabs is $1.6 billion in the Mega Millions lotto. The cash payout? $913.7 million.

That jackpot could soar to $2 billion if there’s no winner, according to the Maryland and Texas Lotteries.

That means the lump sum payout would rise to $1.142 billion.

The odds of winning the $1.6 billion jackpot are currently 1 in 302,575,350, but that hasn’t stopped thousands of people from playing across the country.
