They can choose to bet on a team or individual player and earn winnings based on the amount of money they bet.

How do sportsbooks set their odds?

The head oddsmaker at a sportsbook oversees the creation of the odds for each game. This person relies on a variety of sources to help them set prices, including computer algorithms, power rankings and outside consultants. The odds are displayed in various ways at a sportsbook, but the most common are American odds, which are based on a $100 bet and differ based on which side is expected to win.

Occasionally, a line will open that induces lopsided action on one side. In this case, the sportsbook may move the lines to balance the action and reduce its liability. They might also adjust the lines as more information becomes available, such as injury or lineup news.
