Official betting is a wager placed on a game that is officially sanctioned by the governing body. These bets are set by the sportsbook and include over/under totals, props, and money lines. These bets are available on a variety of games, including American football, basketball, baseball and hockey. The odds for these bets will shift during the course of a game, and the final result may not match the opening line. These bets are also subject to the same rules as traditional wagers, such as requiring extra innings to count toward the total score.
The NFL has signed three sportsbooks as official betting partners, which gives them access to official league data and the ability to promote their relationship with the NFL. MLB has also signed a deal with FanDuel, which will give the US gambling firm co-exclusive rights to online and in-person betting.
Players are not allowed to place bets on NFL games while at team or league facilities. This is because of the prohibition against gambling spelled out in the CBA between the league and its players. However, players are permitted to bet on non-NFL events and can use their own personal funds for these bets.
Legal sports betting is available in 20 states. California had two major propositions on the November ballot that would have made it legal to place wagers in person and online, but both were heavily voted down. The state has since moved to legalize sports betting, with the first sites launching in 2022. The rollout has been slow, as the Gaming Commission had to hire staff, draft regulations, take public input and formally vote on them all.
