"March Madness" may still be a couple of months away, but you should probably start studying up on your NCAA basketball now because a perfect bracket could win you $1 billion.

According to Bleacher Report, Warren Buffett's company, Berkshire Hathaway, is going to join forces with Cleveland Cavs owner, and Quicken Loans founder, Dan Gilbert to give away $1 billion, if someone fills out their "March Madness" bracket absolutely perfectly.

What are the chances of actually filling out a perfect bracket?

1 in 9.2 quintillion. That's EIGHTEEN zeroes, in case you're curious.

Oh, and not only that, but the top twenty brackets will win $100,000 to use towards the purchase, refinance, or remodel of a home.

So, my advice to you: Start watching college basketball non-stop. Learn everything you can about every team you can. Remember last year? Florida Gulf Coast going on a crazy run to break everyone's bracket? Well, if you want to win $1 billion, you have to predict that...along with EVERY OTHER GAME IN THE TOURNAMENT.

The contest will begin March 3rd and is only open to U.S. citizens over the age of 21.
