The bookies are saying it might be one of the closest Superbowl games in history today when the Pittsburgh Steelers meet the Green Bay Packers.
You can bet on the winner, the over/under, the first field goal, first return, even on the coin flip.
But economists are looking at the outcome of the game and betting on the stockmarket to do well afterwards.
Brock University Economics Professor Ernest Bikrimifov says that the "superbowl predictor" has been known for market decays.
He says that if a team from the original NFL wins the superbowl, the stock market will go up, while if a team from the original AFL wins, the market will go down.
Bikrimifov tells us the predictor is about 77 percent accurate.
And he says that because both teams in the superbowl this year are from the original NFL, markets will go up regardless of who wins.
Bikrimifov also says there is another study that found that companies that are based in the city of the superbowl winner do better on the markets.
