More money is bet on football than any other sport, with fans wagering an estimated $100 billion on football annually, though that number includes both the NFL and college football.
The length and number of games mean more money is bet during the 17-week NFL regular season than the three weeks of NFL Playoffs action. The American Gaming Association estimates as many as 38 million adults in the US bet on NFL games throughout the season.
However, the Super Bowl remains the single biggest betting day in all of sports with an estimated $6.8 billion wagered on the Super Bowl in 2020, with better than 1-in-10 American adults, or 26 million people, betting on the game.
