Did you end up with a losing Mega Millions ticket on Friday? If so, take heart: Nobody else won the jackpot either. That means the top prize has now risen to an estimated $1.6 billion.

That’s the largest lottery prize ever, surpassing the $1.59 billion Powerball jackpot drawn in 2016. The previous record for a Mega Millions jackpot was $656 million in 2012. The money was divided evenly by winners in Illinois, Kansas and Maryland.

“We’re somewhat in uncharted territory here,” Gordon Medenica, the lead director of the lottery consortium known as the Mega Millions Group, said on Saturday.

The next Mega Millions drawing will be on Tuesday. The jackpot could rise even more by then, depending on how many tickets sell over the next few days, Mr. Medenica said.
