Illegal wagers: $6-$10 billion
Of the total wagered illegally on football each year, roughly 10 percent is spent on the Super Bowl.
"The Super Bowl has become an American national holiday — a betting holiday," Root says. "That is why it is the most-watched television event of each year. Take away the money, and it's just another sporting event. But with $6 to $10 billion changing hands, it's a life-changing event. The NFL is definitely the king of gambling and the Super Bowl is the crowning event of the football season."
