Sportsbooks are online or brick-and-mortar establishments where people place wagers on a variety of sports events. They offer a wide range of betting options and typically feature competitive odds. The popularity of sportsbooks has grown significantly in recent years, as more and more states legalize sports gambling. It’s estimated that the industry will generate billions of dollars in revenue for states that allow it.

The way sportsbooks make money is simple: for every bet placed, they set a number of odds that reflects the probability of the event occurring. These odds are then used to determine the amount of winnings for each bet. Most of the top U.S. sportsbooks use American odds, which show how much you would win for a $100 bet. They use positive (+) odds to indicate a favorite and negative (-) odds to reflect an underdog.

Another way that sportsbooks make money is through their vig, which is a fee they charge for each bet placed. This fee is often between 100% and 110% of the total amount wagered. The higher the vig, the faster the sportsbook will turn a profit.
