After the US Supreme Court overturned PASPA, state regulators are allowing operators to offer sports betting. While some states have banned or restricted certain types of wagers, others are embracing this new market and creating a variety of sports betting options for bettors to enjoy.

One popular option is official betting. Official betting refers to a type of wager that is graded using information provided by the sports leagues themselves. Several states have passed laws that require official data as part of sports betting, including Tennessee and Illinois.

In a move to increase the integrity of sports events, leagues have pushed for this kind of data to be used in sports betting. While the American Gaming Association supports private commercial agreements with leagues to license data, it opposes legislative mandates that force operators to use official information in their betting products.

A number of states have embraced official betting, and the industry is quickly growing. New Jersey, for example, has several sportsbooks, and there are even sportsbooks inside NFL stadiums. In the NHL, interest surges around opening day and again when the playoffs roll around.

The legality of official betting depends on whether the sportsbook is attempting to profit by selling or otherwise sharing proprietary information with another party, such as an employer or rival. If a sportsbook shares or sells information in order to make money, it may be subject to federal and state fraud and other penalties. In addition, if the sportsbook is attempting to rig a sporting event, it may be in violation of federal and state anti-corruption laws.
