Despite efforts to make states pony up “integrity fees,” a new study by the Nielson Group revealed that a fully mature sports betting industry in the U.S. would contribute as much as $2.3 billion just to the National Football League, which launched its 2018-19 season last month. Commissioned by the American Gaming Association, the study estimated that media rights payments would soar by 18 percent, sponsorship fees would be up 7 percent and ticket sales would increase by 6 percent. All these increases would be due to increased fan interest, which would spur these higher payments. Sara Slane, the senior vice president of public affairs for the AGA, said it puts to rest any complaint that the leagues need “integrity fees” to benefit from legal sports betting. “We think these numbers are conservative and show that the league is frankly tripping over dollars to pick up pennies,” said Slane.
