What is Positive EV (+EV)?
A bet where the expected value is greater than zero — mathematically profitable over a large sample.
Definition
Positive expected value (+EV) is the north star of professional sports betting. A bet is +EV when the bookmaker's offered odds imply a probability lower than the true probability of the outcome. The formula: EV = (true probability × net win) − (1 − true probability) × stake. Over a large sample of +EV bets, profit is statistically inevitable — the same principle that makes casinos profitable in reverse. The challenge is accurately estimating true probability, which is why +EV bettors rely on sharp bookmaker closing lines, statistical models and EV scanner tools like OddsJam and RebelBetting.
Example
Pinnacle no-vig fair price on France ML: 2.10. FanDuel offers 2.30 on same market. EV per $100 = (100 × 1.30 × 1/2.10) − 100 = +$9.5. This is +EV.
