No one matched all six numbers in Tuesday night's Mega Millions drawing, raising the jackpot to a record $476 million.
Julie Baldridge, a spokesman for the Arkansas Scholarship Lottery, said the figure represents the highest jackpot ever in any lottery.
Mega Millions jackpots start at $12 million and grow when no one matches all six numbers. The current jackpot started with a draw on Jan. 25 and had swelled to $376 million in Tuesday's drawing.
The next drawing will occur at 10 p.m. Friday.
