Asher said on a conference call after the court decision that moving bettors to the legal marketplace could be a difficult feat. He said illegal bookmakers have "structural advantages," and that's not only limited to the lack of league integrity fees.
Those books do not pay taxes and they don't have to deal with the compliance issues that regulated books will have. Asher said that states with high tax rates, such as Pennsylvania will find it difficult to compete with the underground market. Pennsylvania is a high tax state for existing gambling operations, and it's expected to treat sportsbooks similarly.
States are hoping to generate a new significant source of revenue from gambling businesses.
"Illegal bookies in Philadelphia and Pittsburgh could hypothetically give bettors a 25 percent rebate on losses and still be better off than the legal bookmakers," Asher said during the conference call with select media members, including CNBC, on Monday. "It's not as if the bookies are out today shopping for new careers."
Geoff Freeman, CEO of the American Gaming Association, is confident that the illegal market will be put out of business but says that it's going to take a partnership from the leagues. He said states structuring their legislation don't "need to reinvent the wheel."
"We have a functioning market and I hope [the states] look at what we have in Nevada," Freeman said on a conference call with the media Monday.
Currently, there is no integrity fee or tax written into any legislation anywhere in the U.S.
"No integrity tax currently in any of these states," Asher said. "[There's] never been an integrity tax in Nevada, no requirement to use league source data. That doesn't exist in Nevada."
Asher added that the integrity fee is not something William Hill believes is warranted.
"There is plenty of money to be made by the professional sports leagues without an integrity tax," Asher said. "They are going to be big winners throughout this for sure."
