The start of the pro and college football seasons led the volume of sports betting in New Jersey to nearly double in September from its level a month earlier.
Figures released Friday by the state Division of Gaming Enforcement show nearly $184 million was bet on sports in New Jersey last month, up from nearly $96 million in August.
Since it began in mid-June, sports betting has attracted over $336 million in bets in the state. The industry in New Jersey has been keeping just under 8 percent of the amount bet as earnings after winning bets are paid out.
New Jersey won a U.S. Supreme Court decision in May that cleared the way for all 50 states to offer sports betting should they choose.
