In sports betting, the plus (+) and minus (-) signs are crucial indicators of potential payouts and the perceived likelihood of an outcome. They primarily relate to moneyline odds, point spreads, and other types of wagers.

Moneyline Odds
On the moneyline, the minus sign (-) identifies the favorite. The number next to it indicates how much you need to bet to win $100. For example, -150 means you must wager $150 to win $100 plus your original stake back.
The plus sign (+) indicates the underdog. The number shows how much you win for every $100 wagered. For instance, +200 means a $100 bet wins $200 in addition to your initial $100.
Point Spreads
The + and ⏤ are also used with point spreads. Here, they indicate which team is favored to win (minus) and which is the underdog (plus), along with the point differential.
Essentially, the + signifies a potentially higher payout for a riskier bet, while the ⎻ indicates a lower payout for a more probable outcome.
Understanding the Implications
The presence of a plus or minus sign heavily influences betting strategy. When betting on a favorite (indicated by the -), you’re essentially paying a premium for a higher probability of winning. While the potential profit is smaller, the risk is theoretically lower.
Conversely, betting on an underdog (indicated by the +) offers a larger potential payout but comes with a greater risk of losing. This strategy is often favored by bettors who believe the underdog has a higher chance of winning than the odds suggest, or those looking for a higher reward.
Beyond Moneyline and Point Spreads
While primarily used in moneyline and point spread betting, the + and ⏤ signs can also appear in prop bets and futures. In these contexts, they still represent the potential payout based on a $100 wager. For example, a player to score the first touchdown might have odds of +500, meaning a $100 bet wins $500 if that player scores first.
Implied Probability
The odds, indicated by the + and ⎻ signs, can be converted into implied probabilities. This helps bettors understand the likelihood of an outcome according to the sportsbook. The formula for calculating implied probability differs slightly depending on whether the odds are positive or negative:
- Positive Odds: Implied Probability = 100 / (Odds + 100)
- Negative Odds: Implied Probability = Odds / (Odds + 100) (ignoring the negative sign)
For example, odds of +200 imply a probability of 33.33%, while odds of -150 imply a probability of 60%.
Mastering the meaning of the + and ⎻ signs in sports betting odds is fundamental to making informed decisions and managing risk effectively. Understanding these symbols allows bettors to assess potential payouts, implied probabilities, and the relative likelihood of different outcomes, ultimately enhancing their overall betting experience.
