Winners are given the choice of receiving the prize in installments or a cash option expected to be around $548 million for Mega Millions and $248 million for Powerball.
Winners are expected to pay a tax rate of 24 percent on the prize upfront, with additional state and local taxes.
The odds of winning the Mega Millions lottery is 1 in 302,575,350, while the odds for the Powerball are 292,201,338.
For both games, winners can take three months to one year to claim the prizes, depending on the state where the ticket was purchased.
