In a nutshell, a sportsbook is an entity that takes bets on sporting events and pays those who correctly predict the outcome of a contest. A typical sportsbook offers a variety of different betting markets that range from traditional straight bets to more exotic proposition bets on individual player performance, specific occurrences and other statistics benchmarks. Some of these bets are closed at the beginning of an event, while others remain open and can be placed during a game (in-play).
The odds used by a sportsbook are calculated using algorithms and do not necessarily reflect real-life probability. However, they are helpful in predicting the amount of money that can be won with a $100 wager on a given team or individual. A sportsbook can also offer point spreads, which are determined by a bookmaker and help balance the action on both sides of a bet.
A sportsbook can make money by collecting a standard commission, known as the vigorish or juice, on losing bets. The rest of the funds are then distributed to those punters who won bets. A sportsbook can also earn revenue by offering futures bets on multi-stage events, such as a season or tournament.
