A gambling sportsbook accepts bets on a variety of sports. Since the Professional and Amateur Sport Protection Act of 1992, sportsbooks have been legal in all 50 states. In addition to sports like basketball and football, sports such as greyhound racing and horse racing are also legal. The Professional and Amateur Sport Protection Act of 1992 limits the number of sports you can wager on, but most states allow sports betting on horse races, baseball, hockey, and greyhound racing. In addition, in some states, such as Montana, you can bet on horse and greyhound races, and even a game of jai alai.

As for the legality of online sports betting, a recent Supreme Court ruling in Tennessee has approved online/mobile sports betting with no retail component. However, these new companies must keep a minimum of 10% of their wagers. In contrast, most other jurisdictions allow a maximum hold of 7 percent or less. In addition, the Virginia Lottery is shaping the market for online sports betting, so it is critical to know what to expect.

Though gambling sportsbooks aren’t legal in every state, they are in a growing number of US states. In addition to New Jersey, Delaware, and South Dakota, several states have passed legislation allowing for the creation of online sportsbooks. Among these states is Kansas, which has recently passed a gambling sportsbook bill. This legislation has been stalled for a while, as conservative groups oppose any form of gambling. Other states such as Massachusetts and Maine have also passed a sports betting bill, but the override failed and the state is yet to pass a law allowing sportsbooks to operate.
