A sportsbook is a gambling establishment that accepts bets on various sporting events. Winning bets are paid out when the event ends or, if it doesn’t end, when the game has been played long enough to be considered official. Some sportsbooks also offer money back on a push against the spread.
The betting market for an NFL game begins to take shape almost two weeks before kickoff, when a few select sportsbooks release what are known as look ahead numbers. These odds are based on the opinions of a handful of sharp bettors and have a bit of arbitrage risk built in to them. For example, if a sportsbook opens the Chicago Cubs at -180, other bookmakers will be reluctant to open their own lines too far off that number for fear of losing action or for the simple fact that they won’t have any edge.
