The major North American sports leagues have all partnered with gambling companies to promote their betting products. These partnerships allow sportsbooks to use official league data in their betting markets and for teams and players to appear in promotional advertisements. NHL superstar Connor McDavid recently appeared in an advertisement for BetGM alongside hockey legend Wayne Gretzky.

The odds on a market change in real time, reflecting the amount of money being placed on each outcome. The more money is placed on an outcome, the lower its odds will be. This is a basic principle of the gambling industry and it can be used to maximise profits on certain types of bets. The most common type of bet is called a totalizators and it’s a form of flexible-rate bet.

Unless otherwise stated, bets on ice hockey games will include overtime and shootouts in all markets. Similarly, if a game is abandoned before 90 minutes are played, all bets will stand. Postponed matches that are rescheduled for within 24 hours will see all bets stand, including those on first goalscorer markets.

NFL players and staff are not permitted to engage in any gambling activity in their own facilities or disclose any nonpublic NFL information while on company business, but they may place non-sports wagers at legally operated casinos and horse/dog racing tracks on their personal time. The NBA constitution doesn’t explicitly forbid its members from betting on sports, but it does say that they can’t place wagers at gambling establishments during the season if their team is involved in a game.
