The biggest Powerball jackpot in U.S. history is $1.6 billion.
On January 13, 2016, the record-shattering jackpot was split three ways. Two of the winning ticket holders came forward soon after the drawing. But, it took six months for the final winners to come foreward -- a couple in Chino Hills, California, who claimed their prize on July 19.
One winning ticket was sold to John and Lisa Robinson of Munford, Tennessee -- who appeared on NBC's "Today" show before ever cashing their ticket in. They opted to take their $528.8 million share of the prize in one lump-sum payment of $327.8 million.
Maureen Smith, a 70-year-old from Melbourne Beach, Florida, also claimed a third of the winnings. She told the Florida Lottery that she had played the lottery -- and bought tickets with the same six numbers -- for years before winning the jackpot.
Mae and Marvin Acosta claimed the prize, but refused to speak to the media. Not much is known about the winners aside from the fact that they waited more than six months to come forward. The Acostas released a statement explaining the delay and saying they had been assembling a team of advisers.
Just In! The second biggest Powerball drawing in U.S. history has now reached $700 million, and that number could rise as more people buy tickets.
The winning numbers will be chosen tonight in Tallahassee, Florida. Some experts from Powerball gave "GMA" a little insight on the overall odds of taking home the grand prize.
If there are no winners tonight, the jackpot will jump to $1 billion, according to an official with DC Lottery. Read more of the news at ABC News.
