Those who place wagers on a sports event using official data supplied by the league are said to be engaging in official betting. This data is often based on the official statistical projections of a game, but can also come from independent research and analysis. The use of official betting information allows sportsbooks to accurately grade bets and avoid potential integrity violations.
The NBA’s official policy on gambling says that players, coaches, trainers and other team staff members cannot bet on NBA games. It also states that any player who bets on a game in which they have an active playing obligation will be declared permanently ineligible for the league. In addition, the NHL’s collective bargaining agreement and constitution prohibit gambling on all NHL games.
Gambling on pro and college sports events is not permitted under NCAA rules, although there are exceptions for certain types of betting like horse racing, MMA and cricket. The NCAA’s prohibition on gambling applies to all student-athletes, coaches and team staff.
Aside from the obvious betting prohibition, student-athletes are prohibited from accepting tips that they know or should have known will be used to bet on a WBSC competition.
Over/Under bets offer odds on the total number of points, goals or runs scored in a game. The Over/Under line is adjusted in real time depending on the share of exchange each outcome has received and takes into account the bookmaker’s return rate. The higher the turnover, the lower the odds and vice versa.
