If won, the colossal amount would rank as the second biggest US lottery jackpot win in history, with the record currently standing at a whopping $1.6 billion.
In fact, with an average winning jackpot prize of $423 million, the Powerball is the world's richest lottery. By comparison, the average jackpot win for the Canada Lotto Max, UK Lotto and South African Powerball draws are $40.9 million, $16.6 million and $1.1 million respectively. 
And, to help players win the big prize, the boffins at Jackpot.com have crunched the numbers to find the world's luckiest lottery numbers. The numbers most frequently drawn are 16, 22, 28, 37, 6 and 3, which might give players inspiration when making their selection.
The last Powerball jackpot win was back in June, where one lucky person claimed a $448 million prize after 19 rollovers. The win before that took just two rollovers before the main prize was claimed, which suggests that a win is well overdue this week.
Pablo Grunbaum, COO of Jackpot.com commented, "The Powerball is known for its huge jackpot amounts and the continued rollovers in recent weeks means the current prize is an astonishing $700 million.
"This amount is considerably higher than the average jackpot prize for other lottos, so there is a real opportunity for people to try a new lottery and see if they can win big. We have 18 of the world's biggest lotteries available to play and with a mega jackpot like this, it might be time to look internationally."
