$20 Billion To Be Bet on Super Bowl 58: 49ers vs. Chiefs

Over $20 billion is estimated to be wagered on Super Bowl LVIII: 49ers vs. Chiefs, according to a report published by the American Gaming Association (AGA).

The survey indicates about 68 million Americans are expected to wager on the big event, which is approximately a quarter of the total U.S. adult population.

There are 37 states (along with Washington, D.C. and Puerto Rico) with some form of legalized sports betting, with the vast majority permitting online sports gambling.

The AGA survey polled 2,204 Americans and the money wagered includes bets placed with a physical sportsbook, online book or with an unlicensed book. The figures also include pool or squares contests done with coworkers, friends or family.

For last year's Super Bowl between the Chiefs and Eagles, about 50.4 million bettors were estimated to have wagered in some form on the game for a total of $16 billion wagered.

This year's survey represents an increase of 35% in American adults wagering on the Super Bowl. The total money wagered has increased about 25% year-over-year.

States such as Massachusetts, Kentucky and Vermont have launched since last year's Super Bowl, with plenty of other operators making inroads in newer states such as Maryland and Ohio.

"As the Super Bowl comes to Las Vegas for the first time, this year's record interest in wagering marks a full circle moment for the U.S. gaming industry," AGA CEO Bill Miller said in a statement. "Our priority remains getting this opportunity right by providing the consumer protections only a regulated market can guarantee and investing in responsible gambling tools, safeguards and education."
