One lucky ticketholder in the US state of Illinois has won the $1.28bn Mega Millions jackpot.
The jackpot has been growing since 15 April when the last jackpot of $20m was won.
Yesterday's winning numbers were 67, 45, 57, 36, 13 and 14.
The winner will be paid the money over 30 years or they will receive $602.5m if they decide to take the cash now, with about a third going in tax.
In the history of the Mega Millions, two jackpots totalling over $1 billion have been won, with the last one in January 2021.
The lottery is played in 45 US states, the District of Columbia and the US Virgin Islands, with draws on Tuesday and Friday.
Punters had been queuing up across America to buy tickets as lottery madness gripped the country.
Among them was Todd Graves, the founder of fast-food chicken chain Raising Cane's.
He said he bought 50,000 tickets for Tuesday's draw and shelled out another $100,000 for last night, promising to share his winnings with his workers.
A Mega Millions spokesperson said: "We are thrilled to have witnessed one of the biggest jackpot wins in Mega Millions history.
"We’re eager to find out who won and look forward to congratulating the winner soon.
"Better still, this exciting jackpot run has had a significant positive impact on the revenues for good causes raised by our member lotteries."
Winners are generally advised to immediately seek assistance from financial advisors, even before claiming the prize money.
Financial planner Robert Pagliarini also recommends that big winners "step outside the craziness of the situation for a moment," and think hard about what parts of their life they "don't want to change".
