The latest estimate, announced around midday Wednesday, is even larger than lottery officials had announced just hours earlier. The initial estimate for Friday's drawing was $476 million, which also would have been a Mega Millions record.
Tuesday's numbers were 9, 19, 34, 44 and 51, with a Mega Ball of 24. That drawing was for an estimated $363 million jackpot, which would have been the game's third-largest.
Forty-seven tickets earned a pre-tax prize of at least $250,000 each by matching five numbers without matching the Mega Ball. Nine California winners will get $308,573 each because of parimutuel rules in that state.
The game's previous biggest jackpot was $390 million in a March 6, 2007, drawing. That jackpot was split by winners in Georgia and New Jersey.
The growing jackpot has drawn plenty of interest from would-be millionaires. On Monday, lottery officials announced that "stronger than expected sales" prompted them to push up Tuesday's jackpot up from an initial estimate of $356 million to $363 million.
"I see so many different faces every day, and it's not just Tuesday and Friday that they come in. It's every day of the week," Latasha Allen, a manager at a Columbus, Georgia, convenience store, told CNN affiliate WTVM-TV this week about the growing number of lottery players in recent days.
Friday's $500 million prize is payable as an annuity over 26 years. If a winner prefers, he or she could choose a one-time, lump-sum payment, which in this case would be $359 million. Both figures are before taxes.
This prize has been building since January 24 when a Georgia woman won a $72 million Mega Millions prize. She chose a $52 million lump-sum cash option.
Last year, the game stopped just short of breaking its record. A $380 million jackpot was split by two winners, one in Idaho and another in Washington, on January 4, 2011.
The biggest single-ticket win in the other nationwide lottery, the Powerball, was in February 2006 when a ticket held by eight workers at a Nebraska food plant paid a $365 million jackpot.
Mega Millions is played in 42 states plus the District of Columbia and the U.S. Virgin Islands.
A jackpot-winning ticket must match all five numbers drawn from a pot containing 56 balls and then match the Mega Ball, which is drawn from a pot containing 46 numbers. Odds of winning are almost 176 million to 1. Each ticket costs $1.
Jackpots start at $12 million and rise for subsequent drawings when jackpot-winning tickets aren't sold.
