The Different Business Models of a Sportsbook

A sportsbook is an establishment that accepts bets on a variety of sporting events. It charges a commission, known as the vig or juice, on losing bets. It uses the remaining money to pay winners. The vig is what guarantees sportsbooks a profit over the long term. Sportsbooks also set odds that differ from the true probability of an event. These odds, combined with vig and other fees, create a financial edge for the bookmaker over the gamblers that place bets with them.

Retail sportsbooks must balance two competing concerns: they want to drive as much volume as possible (especially on the most reliable customers who can be counted on to click in bets without question), and they are perpetually afraid that some of their customers will know more about their markets than them. To combat these problems, retail sportsbooks typically take protective measures: They have relatively low betting limits (especially for bets placed on their apps or websites instead of over the counter), they advertise on TV, offer loss rebates, promote odds boosted markets and do everything they can to curtail arbitrage.

It’s important to understand the different business models of a sportsbook in order to bet intelligently and responsibly. No single operator will operate at either extreme described here, and subsets of sportsbooks may even use different models within their own lines. Regardless, it’s important to be aware of these concepts so that you can compare prices and features between different sportsbooks.
