What Is Expected Value (EV) in Sports Betting?

Expected Value (EV) is a key concept in smart sports betting. It helps you measure how profitable a bet is in the long run by comparing the odds with the actual probability of winning. In short: EV tells you whether a bet has a positive or negative edge.

If a bet has positive expected value (+EV), it means you’re getting good odds compared to the true chance of winning — a bet worth making. If it’s negative (-EV), the odds are stacked against you, and the bet will likely lose money over time.

Professional and sharp bettors rely on EV calculations to make mathematically sound decisions instead of betting on gut feeling or hype.
