A single ticket holder in South Carolina will claim that bounty, Mega Millions said on its website.
The six winning numbers drawn on Tuesday night were 5, 28, 62, 65, 70 and 5 again as the special Mega Ball.
The record jackpot had set off a lottery frenzy across America, with people lining up at convenience stores, supermarkets and liquor stores to buy a two dollar ticket that gave them a roughly one in 300 million chance of winning.
The winner can take $913m in a lump sum cash payment or the whole pile in annuities over 29 years.
The jackpot got so big because no one had won since July, when a group of office workers in California shared $543m.
Until now the US record jackpot was $1.586bn for a different lottery, called Powerball, in 2016.
It was split three ways by ticket holders in California, Florida and Tennessee. Each took home $528.8m.
