How is a lottery jackpot split between winners?
Powerball and Mega Millions jackpots are pari-mutuel, meaning the jackpot is one pool shared by however many tickets win it. Powerball's FAQ says that with several jackpot-winning tickets in one drawing, the jackpot "is split among all winning tickets." The Mega Millions rules say the same in fewer words: "the jackpot prize will be shared." Two winning tickets get half each, three get a third each, and so on.
The split is by ticket, not by person. If ten coworkers share one winning ticket and a stranger holds the other, the coworkers split one half among themselves and the stranger keeps the other half.
Each ticket's share is handled separately. One winner can take the annuity while the other takes the lump sum, and each claims in the state that sold their ticket. Winners usually learn about each other the same way everyone else does, when the lotteries announce where the winning tickets were sold.
What was the biggest split lottery jackpot?
The best-known split is the $1.586 billion Powerball jackpot drawn on January 13, 2016, then the largest in history. Three tickets won it, sold in California, Florida and Tennessee. Each share was worth $528.8 million as an annuity or about $327.8 million in cash, before taxes.
The largest jackpot ever shared came later. On September 6, 2025, two tickets split a $1.787 billion Powerball jackpot, one sold in Missouri and one in Texas. Each winner could take an $893.5 million annuity or a $410.3 million lump sum. The overall record, $2.04 billion in November 2022, went to a single ticket in California. Other multi-winner draws are listed in the biggest jackpots ever won, and our Powerball jackpot history chart shows every reset.
Are smaller lottery prizes split between winners?
Not outside California. The lower Powerball and Mega Millions prizes are fixed amounts, paid in full to every winning ticket. Matching five white balls on Powerball pays $1 million to each ticket that does it, whether there's one such ticket or forty. On Mega Millions the same match pays $2 million to $10 million per ticket, depending on the multiplier printed on the ticket.
California is the exception. It pays every Powerball and Mega Millions prize tier pari-mutuel. Powerball's prize chart notes that in California "prize payout amounts are pari-mutuel and determined by sales and the number of winners." A night with many Match 5 winners in California means each gets less than $1 million, and a night with few can mean more. The reasons are covered in why California lottery prizes are pari-mutuel, and the full prize ladder is in how many numbers you need to win.
Is a split more likely when the jackpot is big?
Yes. Your own odds don't change, but the chance that someone else also holds the winning combination grows with every ticket sold, and record jackpots sell far more tickets. Avoiding popular choices helps a little here. Many players use birthdays, which bunches their numbers at 31 and below, so a ticket built from dates is more likely to be duplicated. Picking differently can't improve your chance of winning, but it can lower your chance of sharing. How to pick lottery numbers goes through what does and doesn't matter.
What if the two winners are on the same ticket?
Then the lottery doesn't split anything. It pays the ticket, and how the money is divided among the people behind it is a private matter, settled by whatever agreement they can prove. This is where real disputes happen. If you play with family, friends or coworkers, write down who's in and how a prize would be shared before the drawing. Our office lottery pool guide covers how to set that up.
Rules for group claims vary by state. In California, for example, group winners of a jackpot all have to choose the same payment option, or the prize is paid as an annuity. Sharing winnings after the fact can also have gift-tax consequences, covered in giving lottery winnings to family.
