How Sportsbooks Earn Their Edge

A sportsbook is a gambling establishment that accepts wagers on different sporting events. It is a specialized service that often includes separate racebooks, casinos and live dealer betting platforms. Sportsbooks feature large menus of different sports, leagues and events as well as offer fair odds for all bet types.

It is important for punters to understand how sportsbooks earn their edge in order to make the most of their betting experience. This will help them become savvier bettors and recognize mispriced lines. In addition, understanding what products a sportsbook offers can increase profitability as well. For example, bonus bets and boosts create edges that can be exploited by savvy bettors.

Odds are a key tool for sportsbooks as they balance risk on both sides of an event. They do this by setting odds that are designed to attract a balanced amount of action on each side of an event with the goal of earning money regardless of the outcome of the wager. Occasionally, though, action will be imbalanced and the sportsbook needs to manage that risk as well. This can be done by either adjusting the odds, engaging in offsetting bets (“laying off”) or by directly limiting customers.

Sportsbooks also earn money by collecting a fee, known as vigorish, on winning bets. This is commonly a 10% commission but can be higher or lower at some books. Sportsbooks also charge an additional fee, called juice, on losing bets to cover their arithmetic liabilities. This is often the biggest source of profit for most sportsbooks, although they will also generate revenue from other sources such as rebates, props and individual player markets.
