FOR THE WINNER of a $1.26-billion Mega Millions jackpot ticket sold in California, the ecstasy of the big win may soon give way to the anxiety over some big choices.

鈥淭his is a life-changing moment and they don鈥檛 need to make every decision right away,鈥 said Matthew Liebman, chief executive officer and founding partner of Amplius Wealth Advisors.

Mr. Liebman鈥檚 first advice was to build strong relationships with four different advisers: a wealth adviser, a tax accountant, an estate attorney and a therapist before making any decision about payout.

Friday鈥檚 jackpot was the fifth-largest Mega Millions prize in US history and the winning ticket was sold at Sunshine Food and Gas in Cottonwood, a census designated area with a population of about 6,000 people, in Shasta County, about 150 miles (241.4 kilometers) north of Sacramento. The identity of the winner (or winners) wasn鈥檛 immediately known.

While most lottery grand prize winners typically chose the cash payout, which in this case will be about , financial planners still say there鈥檚 reason to opt for the annuity 鈥 distributed over 30 annual payments.

鈥淭he annuity typically is a bigger payout,鈥 said Anthony Love, managing director of tax and trust at Quotient Wealth Partners. If the winner is young and healthy, it鈥檚 probably a better option, he advised. Those who take the annuity can also avoid the potential pitfall of watching their earnings evaporate through bad investments or other financial decisions.

If the winner is older, the lump sum may be the better choice, Mr. Love said. 鈥淚f you accept the lump sum, you get all the money at one time, you get to invest the money however you want it to be invested, and you鈥檙e paying tax at a time where the effective tax rate is the lowest in a generation,鈥 he said.

Massive lottery prizes in the US have become increasingly common in recent years, attributed to changes in game rules and higher ticket prices. Since 2016, more than 10 jackpots have exceeded $1 billion, including three in 2024 alone.

Billionaire Mark Cuban has also had some well-considered advice for lottery winners. He the Dallas Morning News in 2016 that winners should hire a tax attorney, avoid taking the lump sum and say no to friends and relatives who ask for money. Having a lot of money won鈥檛 instantly make you a good investor, so winners should also put money in the bank and keep it safe, he said.

Mr. Liebman, of Amplius Wealth Advisors, also advised the winning ticket holder to take a deep breath.

鈥淚 say that seriously because, from what I have understood from past lottery winners, is that it can be a big strain on their mental health,鈥 he said.

The last Mega Millions jackpot win happened in September, when a ticket claimed an $810-million prize. The record-setting Mega Millions jackpot of $1.58 billion was won in Florida in August 2023. Only three larger jackpots, all from Powerball, have surpassed that amount. 鈥 Bloomberg
