As of 2015, Super Bowl betting in the United States is only legal in Nevada. Though some states, such as New Jersey, have attempted to legalize and regulate sports betting, the major professional and collegiate sporting organizations have consistently opposed this practice.
In the United States, the majority of legal Super Bowl betting occurs in Las Vegas, where its popularity has been rising. Nevada gamblers won a combined $19,673,960 from wagers on the 2014 Super Bowl, a 21 percent increase over the prior year. Overall, bettors in Nevada legally wagered $119,400,882.
Despite legal restrictions, sports betting has risen in popularity outside of Nevada as well. The American Gaming Association estimated that $3.8 billion was illegally wagered on the 2015 Super Bowl.
