The increase from $654 million reflects a surge in ticket sales.
And Friday's Mega Millions wasn't a complete bust. The next Powerball drawing will be held Wednesday at 10:59 p.m. ET and tickets also must be purchased by 10:00 p.m. that day to be eligible. That distinction goes to the $1.586 Powerball jackpot in 2016 that was shared by three winners, including a Chino Hills couple.
The reason these jackpots have ballooned to such monstrous proportions is because, well, no one has won in a while.
It got that enormous because no one's won the jackpot since July 24, when a group of 11 co-workers in Santa Clara County, Calif., split a $543 million prize.
Wednesday night's Powerball drawing will be the 19th since the jackpot was last hit August 11, when a $245.6 million jackpot was won on a ticket sold in NY.
The estimated prize is just shy of the all-time game record of $656 million set in 2012.
A Super Kansas Cash ticket that matches all numbers Monday night will win a cash jackpot estimated at $3.01 million, the fifth largest jackpot for that game.
The next drawing will be October 17 with the prize of $345 million.
