The Super Bowl is expected to obliterate betting records

Atlantic City, N.J. — Nearly 68 million American adults - about 1 in 4 - plan to bet on this year's Super Bowl, setting a record by a wide margin, according to the gambling industry's national trade association.

Figures released Tuesday by the American Gaming Association include bets placed with legal outlets, as well as with illegal bookies and online operations in other countries.

The volume of betting participation is projected to be 35% higher than last year, when the previous record was set.
