Positive EV (Estimated Value)

Overview

Positive EV is short for positive expected value. This term applies to bets that have a greater probability than what is implied by the sportsbook’s odds. Positive EV betting is the most consistent way to make long-term profit. Essentially, the better assumes the margin regularly imposed by the sportsbooks.Sportsbooks try to limit all opportunities for EV sports betting, meaning the bettor must be selective with their bets.

Positive EV at Monster.Bet

At Monster.Bet, our picks incorporate positive EV to help identify our best bets. Here’s an example of positive EV betting in action. Pretend that the New York Yankees and the Baltimore Orioles are both -110 on the moneyline against one another. -110 odds imply a 52.4 percent chance, meaning that both teams are projected to win 52.4 percent of the time.

If a bettor decides (usually through modeling) that the Orioles actually have a 55 percent chance to win, then they have identified a positive EV bet. From there, they’ll want to line shop to find the best odds for the bet and then place their wager.
