Official betting is a form of wagering on sporting events that takes place at legal sportsbooks. Those who place bets are paid if their selection wins. There are several different types of bets, including moneyline, point spread and parlay. Sportsbooks are licensed and regulated by the state in which they operate. Bettors must be of legal age to place bets. Bettors must also verify their identity and location before placing a bet.

NBA Commissioner Adam Silver has been an outspoken critic of the expansion of legalized sports betting, arguing that it could lead to more attempts to fix games for gambling purposes. He has also argued that it would be difficult to monitor. But the NBA has now shifted its position, joining the ranks of other leagues that have made partnerships with US sportsbooks. In 2023, it signed a deal with DraftKings and FanDuel to support responsible gambling and ensure the integrity of NBA games.

The NBA is working closely with both operators to promote responsible gambling through public education and social media messaging, as well as implementing best-in-class standards and limitations on betting-related advertising across the NBA platform and partner platforms. It has also partnered with the National Council on Problem Gambling to help educate players and fans about responsible gambling.

While the NBA has made strides in educating players and fans about responsible gambling, other professional sports leagues have taken a tougher line. The NFL, for example, has punished players who have placed bets on their own teams and games. For example, the NFL’s personal conduct policy states that anyone who bets on a game while in uniform or at team or league facilities will be subject to a minimum one-year suspension.
