Whether you win the whole jackpot or even some amount from Wednesday night's drawing, before turning in your ticket, you will need to protect yourself, your family and your money.
Wednesday's Powerball numbers were 8, 27, 34, 4, 19 and the Powerball is 10.
Many in Texoma were dreaming big. One and a half billion big bucks, and most have an idea what they would do if they win Wednesday's Powerball.
"Reason I'm up here right now is to buy a Powerball ticket. I figure my money is as good as anybody else's, and that way I can call my boss in the morning and tell him I'm retired."
"Pay off my family's bills and build a great big old arena."
But winning such a large amount of money can have a downside.
"This is the largest Powerball in history. Somebody is going to win a lot of money, maybe multiple winners," said John Mabary, an Edward Jones financial advisor in Sherman. "But those people are going to be hit up for money that they haven't had in the past, and it's going to be kind of easy to blow this if you're not careful."
Financial advisors and insurance agents say the first thing to do is secure your ticket.
"The first thing I would do is take copies of both sides of the the ticket, and I'd put that ticket in the safe deposit box or a personal secure locker," said Sandra Phillips, a State Farm agent in Denison.
And protect your privacy by not announcing your big win or make rash decisions.
"One thing I would tell people not to do is make rash decisions like quitting your job, going and buying a new house or a bunch of debt obligations," Mabary said. "There's going to be plenty of time for that and think through what you want to spend money on."
Mabary and Phillips advise you to assemble a team with an accountant, an attorney and financial advisor to help you manage the money.
"You can actually do better by taking the lump sum if you invest," Mabary said. "Now if you go and blow the lump sum, you should have taken the annuity payout.
But if no one wins Wednesday's Powerball and the pot grows, Mabary warns of buying more tickets.
"People are taking more money than they can afford to do with the hopes that they hit it rich and that's really a bad idea," he said. "Don't wipe out your savings just to go buy a lottery ticket."
Advisors and agents say if you won, you should also designate heirs if you choose, create a plan where money will go when you die and invest or place some amount of money in a banking account. But remember, the government only insures individual bank accounts up to $250,000.
