Some markets, like future bets, may display only + odds. The odds mean that you have to bet $115 on the Chiefs to win $100, while a $100 stake on the Colts will earn $165 in profits. So the sign attached to the odds reveals the team's strength and which one has a higher chance of winning.įrom the above, the Chiefs are the favorite, and Colts are the underdogs. On the other hand, a team with the '+' is the underdog. A team with the '-' sign means they are the favorite to win the event. To simplify, it's necessary first to understand the meaning of the plus (+) and minus (-) symbols besides the odds. Basically, American odds are based on $100, so the lines available on any market tell you how much you need to spend to win $100 or how much you win from spending $100.
