The term official betting refers to wagers that utilize data provided by a sports league. A number of states that have legalized sports betting require the use of official data for Tier 1 bets. Others have opted to let sportsbooks grade Tier 2 bets on their own. The American Gaming Association supports private commercial agreements for official betting data and opposes legislative mandates.

All in-uniform personnel at NHL games – players, coaches, team and league employees – are prohibited from placing bets on hockey. The NHL’s collective bargaining agreement stipulates that gambling on any NHL game is illegal, and this rule is posted in every dressing room. The NHL also conducts an annual screening of its employees to determine whether anyone has criminal charges or convictions involving gambling or sports wagering.

Those who violate the NHL’s rules on gambling face discipline. For example, a player who places a bet while at a team or league facility can be suspended for up to one year. In addition, a player who bets against his or her own team can be penalized with a six-game suspension.

The NBA has a similar policy, with all in-uniform personnel banned from sports betting. However, players and personnel can place bets on non-NBA events. This includes Super Bowl squares, NCAA tournament brackets and fantasy sports. The league collaborates with regulators, sportsbooks and independent integrity monitors to enforce its policies, and it conducts in-house investigations of any suspected violations.
