Sports betting is the activity of predicting sports results and placing a wager on the outcome. The frequency of sports bet upon varies by culture, with the vast majority of bets being placed on association football , American football , basketball , baseball , hockey , track cycling , auto racing , mixed martial arts and boxing at both the amateur and professional levels.
Sports betting can also extend to non-athletic events, such as reality show contests and political elections, and non-human contests such as horse racing , greyhound racing and illegal, underground dog fighting. The term "book" is a reference to the books used by wagebrokers to track wagers, payouts, and debts.
The majority of legal sportsbooks are found online, operated over the internet from jurisdictions separate from the clients they serve, usually to get around various gambling laws such as the Unlawful Internet Gambling Enforcement Act of in the United States in select markets, such as Las Vegas , Nevada , or on gambling cruises through self-serve kiosks. They take bets "up-front", meaning the bettor must pay the sportsbook before placing the bet.
Illegal bookies, due to the nature of their business, can operate literally anywhere but only require money from losing bettors and don't require the wagered money up front, creating the possibility of debt to the bookie from the bettor. This creates a number of other criminal elements, thus furthering their illegality.
Sportsbetting has resulted in a number of scandals in sport, affecting the integrity of sports events through various acts including point shaving players affecting the score by missing shots , spot-fixing a player action is fixed , bad calls from officials at key moments, and overall match fixing the overall result of the event is fixed. To determine who wins against the spread, the line is either added or subtracted from a team's final score. In the above example, if the bettor chose Miami, he would subtract 3 points from Miami's final score and compare that to Oklahoma City's final score.
If taking Oklahoma City, he will add 3 points to Oklahoma City's final score. And if a bettor took Oklahoma City, they would have to win outright or lose by less than 3 points.
If the final adjusted score is a tie, the bet is considered a push. This is the most common type of bet in American sports betting. The possible payout of the parlay is determined by the combined likelihood of all bets placed. A parlay of riskier bets more underdogs will pay greater than a parlay of more likely bets more favorites. Although the rules to win his bet are the same as a parlay, he is paid less than a regular parlay due to the increased odds of winning. A sports book may choose to buy in-play futures wagers at a price below the actual payout before a championship is decided if the potential payout is very high and thus, damaging to the sports book due to the money that may be lost.
The bookmaker functions as a market maker for sports wagers, most of which have a binary outcome: The bookmaker accepts both wagers, and maintains a spread the vigorish which will ensure a profit regardless of the outcome of the wager. Bookmakers usually hold an advantage over their customers—for small wagers it is closer to a advantage—so the bookmaker will most likely survive over the long term. Successful bookmakers must be able to withstand a large short term loss.
Many of the leading gambling bookmakers from the s to the s got their start during the prohibition era of the s. They were often descendants of the influx of immigrants coming into the USA at this time. Although the common stereotype is that these bookies were of Italian descent, many leading bookies were of eastern European ancestry. Odds for different outcomes in single bet are presented either in European format decimal odds , UK format fractional odds , or American format moneyline odds.
European format decimal odds are used in continental Europe, Canada, and Australia. They are the ratio of the full payout to the stake, in a decimal format. Decimal odds of 2. UK format fractional odds are used by British bookmakers. US format odds are the amount won on a stake when positive and the stake needed to win when negative. US odds of are an even bet. In Asian betting markets, other frequently used formats for expressing odds include Hong Kong, Malaysian, and Indonesian-style odds formats.
Odds are also quite often expressed in terms of implied probability , which corresponds to the probability with which the event in question would need to occur for the bet to be a break-even proposition on the average. In setting odds , the bookmaker is subject to a number of limitations: In many countries, bookmaking the profession of accepting sports wagers is regulated but not criminalized. In areas where sports betting is illegal, bettors usually make their sports wagers with illicit bookmakers known colloquially as "bookies" and on the Internet , where thousands of online bookmakers accept wagers on sporting events around the world.
The National Football League is fully against any sort of legalization of sports betting, strongly protesting it as to not bring corruption into the game.

The positions of the four major American sports leagues representing American football , baseball , basketball and ice hockey have become more complex since their decision to embrace daily fantasy sports DFS in , which are described by those within the industry as "almost identical to a casino" in nature.
With the contention by critics that such activities blur the lines between gambling and fantasy sports, the endorsement of all four major sports leagues and many individual franchises provided a marked contrast to their positions on betting. While the National Basketball Association NBA was once active in preventing sports betting law relaxation, current NBA Commissioner Adam Silver became the first major sports leader to break from previous administrative opposition to gambling.
In he stated in a New York Times op-ed, "I believe that sports betting should be brought out of the underground and into the sunlight where it can be appropriately monitored and regulated. Major League Baseball MLB Commissioner Rob Manfred has also advocated the league changing its stance on sports betting, with both Manfred and Silver noting that the scale of illegal sports betting makes opposition to betting meaningless.
He also stated a willingness to "try to shape" any future legislation at federal level. This was noted as a marked contrast to former Commissioner of the MLB Bud Selig , with Manfred going beyond tacit approval and stating, "There is this buzz out there in terms of people feeling that there may be an opportunity here for additional legalized sports betting.
