With sports betting becoming more widespread in the United States, it’s a safe bet that more professional leagues will find ways to partner with and make money from regulated operators. The NBA, for instance, works with regulators and integrity firms to monitor betting patterns and conduct in-house investigations on potential rule violations.

Aside from the aforementioned policies, the NBA also prohibits anyone playing or working for a team from gambling on its events. This includes the NBA itself, its summer leagues and WNBA and G-League. However, players and those working for teams can bet on non-NBA games if they wish to.

The NHL also has a rule against gambling, posted in every dressing room and in the league constitution, that applies to all players and employees of the league. It prohibits them from placing wagers on any NHL game, though it’s not clear what the penalty would be if someone were to violate this policy.

While New Jersey, the first state to legalize betting, continues to set records thanks to a competitive and operator-friendly system, other states are still catching up. Massachusetts passed a law in 2022 and will launch its sportsbooks on March 10, just ahead of the NCAA Tournament.

New Mexico also didn’t pass a law, but Native American tribes in the state have been running sportsbooks since October 2018. They’re doing so under a waiver of the federal ban on class III gaming. This makes the state a “grey area” where lawmakers haven’t passed a bill but the Department of Interior, which oversees tribal gaming compacts with states, hasn’t intervened.
