The betting market for NFL games begins taking shape almost two weeks before kickoff. Each Tuesday a handful of sportsbooks release so-called “look ahead” lines, or 12-day numbers, for next week’s games. These odds are based on the opinions of some sharp bettors and are often a thousand bucks or so below the maximum that professional sharps would risk on a single game.
Sportsbooks compile their odds by balancing the stakes and liability for each outcome. They then change those odds to attract action from certain groups while discouraging others. For example, if a long-term winning player likes the Lions to cover the spread against the Bears, a sportsbook may move the line to encourage Chicago backers and discourage Detroit bettors.
A custom sportsbook can be developed to fit the specific needs of a business. It takes time to create a unique offering, but there are benefits to a customised product. The main advantage is that it will be a proprietary product and there will be no danger of a competitor copying a new feature.
