The OddsFantasy positive EV bet finder lists bets whose odds are higher than the fair odds of sharp bookmakers such as Pinnacle, once their margin is removed. Each row shows the EV %, the event, the market, the bet, the odds and the sportsbook, for pre-match and live markets. On Polymarket, qualifying value bets can also be placed for you automatically, with your own filters and stake. Positive EV bets are what many bettors call value bets, so this is a value bet finder too.
A bet has positive expected value (+EV) when its odds pay more than the outcome's true chance justifies. If an outcome has a 50% fair probability, its fair odds are 2.00, so any price above 2.00 is +EV. Over many bets, +EV bets are expected to return more than you stake, even though any single bet can still lose.
EV % = (offered odds ÷ fair odds − 1) × 100
Fair odds 2.00, offered odds 2.10:
EV % = (2.10 ÷ 2.00 − 1) × 100 = +5%Fair odds are an estimate, not a guarantee. Prices move, and EV is an average over many bets, so size each stake with a plan such as fractional Kelly.
Placing value bets by hand is slow: prices move within minutes and an edge can disappear before you act. OddsFantasy's positive EV automation can place qualifying value bets on Polymarket for you, using your minimum and maximum EV, odds range, sports, maximum spread, minimum volume and stake per market.
By default it enters with a resting limit order. With market entry switched on it fills immediately, and it skips the bet if the price has moved beyond your slippage limit. When a value bet disappears from the feed, the automation cancels its unfilled order. Automation needs an automation key saved in your trading wallet.
Yes. A value bet is a bet whose odds are higher than its true chance of winning justifies, which is exactly a positive expected value (+EV) bet. The finder measures that true chance from sharp bookmakers' no-vig odds and shows the edge as EV %.
Positive EV betting is expected to be profitable over a large number of bets, because each bet pays more than its estimated fair value. Individual bets still lose often, results swing widely over short periods, and the edge is only as good as the fair odds it is measured against.
From sharp bookmakers such as Pinnacle, whose prices are widely used as an estimate of true probability. The finder removes their margin to get no-vig fair odds before it compares prices. You can do the same calculation by hand with the vig calculator.
Enter the offered odds, the fair odds and your stake in the EV calculator. It returns the expected value in money and as a percentage of the stake.
No. You set your filters and stake in the positive EV tool and switch on automation, and OddsFantasy places qualifying value bets on Polymarket for you.
