Official betting is wagering on a game based on data and results that are sourced from the governing body of the sport in question. These bets typically have lower odds than a normal wager and are accepted by many different sportsbooks and betting apps. In recent years, there has been a fierce battle between the US gambling industry and the leagues over how this information is used.

The NFL and NBA are the two major sports that have officially partnered with betting operators, making it legal for players and team staff to place bets online. The NBA has also teamed up with FanDuel to offer an official baseball betting partnership.

While betting on professional sporting events is legal in most states, it’s important to know the rules before placing your bet. If you’re unsure of what the rules are, it’s a good idea to contact the state’s regulatory agency for more information.

If a game is abandoned, all bets will be void unless the market was already settled prior to abandonment. In markets that include multiple teams, all players must start for bets to stand – this includes substitutes. For top goalscorer markets, only goals scored during regular time or extra time via penalty will count. Dead heat rules apply for match result markets that end in a tie.

Players and league employees are barred from placing bets on any NBA-related markets. However, if sports betting is legal where they’re located and they don’t bet on the NBA, the G-League or Basketball Africa League, they’re allowed to make other wagers. In addition, anyone who bets on their own team or league will be suspended for at least one season.
