The amount of money bet on the Super Bowl varies from year to year and is difficult to quantify precisely due to the presence of both legal and illegal betting markets. However, as of my last update, it is estimated that Americans bet tens of billions of dollars on the Super Bowl each year.
In the legal sports betting market alone, which has been rapidly expanding in the United States since the Supreme Court struck down the Professional and Amateur Sports Protection Act (PASPA) in 2018, the numbers are substantial. For example, in 2021, legal sportsbooks in the US reported about $1.3 billion in wagers placed on the Super Bowl, according to the American Gaming Association (AGA).
It’s important to note that this figure does not include illegal betting, which is estimated to be much larger. Some reports suggest that the illegal betting market for the Super Bowl could be several times larger than the legal market.
Please keep in mind that these figures are subject to change, and for the most current data, you would need to refer to the latest reports from the AGA or other authoritative sources in the gaming industry.
