Sports Betting

Betting on sporting events is a common form of gambling around the world, involving billions of dollars annually. Large events such as the Super Bowl or the World Series alone can generate wagers totaling billions of dollars. In addition to legal sports betting, such as wagers made in casinos, illegal sports gambling flourishes globally. Rigid enforcement of sports gambling laws remains difficult because much of the betting is placed with private individuals or with companies located in countries where such wagering is legal. Internet gambling sites, which can be based anywhere in the world, are a growing source of sports gambling.Legal in many other parts of the world, betting on individual sporting events in the United States is allowed only in Nevada. In part this is because of the potential for events to be fixed, or illegally influenced.There have been a number of high-profile sports gambling scandals in history, including the fixing of the 1919 World Series by Chicago White Sox players, who were paid by gamblers to lose the series. Another scandal involved professional baseball player and manager Pete Rose, who was banned from the sport and barred from entering the Baseball Hall of Fame because of his gambling. Most sports leagues and associations have strict rules against players betting on sports or associating with gamblers. Sports betting typically involves odds or point spreads that affect the bet or the payout. A bet with odds of five-to-one means that a winning bettor will collect five dollars for every dollar bet. With a point spread, one team is favored by a certain amount of points. For example, if a bettor decides to wager on a team favored by 12 points, then he or she wins only if that team wins the game by more than 12 points. If there are no odds or point spread given, then the wager is known as an even-money bet. There are many other types of sports wagers, including combination bets, depending on the sport and the specific regulations that apply to it.Horse racing has long been one of the most common types of legal sports gambling. Many large cities have tracks dedicated to horse racing. More than 150 racetracks were operating in the early 2000s in the United States. Gambling at these tracks is governed by the pari-mutuel betting system.Under this system all money bet on a race is placed in a pool and split between winning bettors, minus a percentage that goes to the track. The odds are determined by how much money is bet on each horse, with the more money bet, the lower the odds. By the beginning of the 21st century pari-mutuel betting on horse racing in the United States-including wagers allowed away from the track, know as off-track betting-totaled more than $16 billion annually. See also Harness Racing.Dog racing, which also uses the pari-mutuel system, is legal in some states but is not as widespread as horse racing. Betting on animal fights, such as cockfighting or bullfighting, has become even more limited because of animal cruelty laws that outlaw these sports. Animal fighting is an example of a type of gambling that has been banned in the United States but is still legal in some other countries, which have different cultural traditions and often less stringent gambling laws. It is also operated illegally in many places.
