What Is a Sportsbook?

A sportsbook is a place where gamblers can place bets on different sporting events. They offer odds on a variety of different wagers and pay out winnings to punters who win their bets.


Several US states have legalized sports betting since the 2018 Supreme Court ruling, and many are now expanding their markets with new sportsbooks. However, you should do your research to find a sportsbook that is legitimate in your state and has a valid license.


A sportsbook makes money by charging a commission, known as the vigorish, on winning bets and using the remaining amount to pay out winnings. The vigorish is usually around 10%, although it can vary from one book to the next.

Marketing and advertising

As sports betting expands, so does the amount of money that sportsbooks can collect from promotional offers. The value of such deals has become a significant part of their inflows, especially in statewide markets like Nevada and Colorado.

Over/under bets

Over/under bets are a popular type of bet on football games, as well as other sports. They are based on the total number of points scored by both teams combined. The team that scores the most points will win, and if the number is over the line set by the sportsbook, you’ll win your bet.

Point spreads

The public tends to wager heavily on favored teams, so sportsbooks move the lines and odds in their favor to make them more appealing. They’ll also offer more favorable lines if the majority of public action is on the underdog. This gives you an opportunity to fade the public, if you think they’re wrong on their pick and that the team will actually lose by less than the public expects.
