After the Supreme Court ruled that individual states could regulate sports betting on their own, many of them jumped on the opportunity. But each state’s approach is a little different. Some have taken a cautious approach, while others have embraced it fully.

Some states have adopted a more proactive stance on regulating the industry, including requiring sportsbooks to use third-party integrity monitors to ensure that betting is fair and transparent. And some have mandated that sportsbooks report information about the results of bets on NFL games to the league, which will then identify any violations.

The NFL has a similar policy, and the league is making sure it’s catching offenders by beefing up its in-house technology, dedicating security personnel to the space and collaborating with regulators, sportsbooks and independent integrity firms. The NFL also has a system that tracks all bets placed on its events and where they’re made, giving the league a clearer picture of the betting market.

The NHL has a more relaxed position on sports betting, though some of its teams in markets with legal wagering have signed sponsorship deals with bookmakers. For example, the Vegas Golden Knights have a multi-year deal with William Hill that includes betting partnerships and access to in-game data. The NHL is smaller than the NBA and NFL, so it’s less likely to run into any issues with gambling. But the league does have a zero-tolerance policy for player and coaching staff members who place bets.
