How to use this tool
- Enter the stake and odds of the bet you already placed.
- Enter the current price for the opposite outcome — another sportsbook or a prediction-market contract.
- Place the suggested hedge stake; both scenarios then return the same profit.
The formula
Hedge stake = (original stake × original decimal) ÷ hedge decimal- original stake × original decimal = your potential total return
- hedge decimal = decimal odds of the opposite side
Worked example
A $100 bet at +200 returns $300 if it wins. Hedging at −110 (1.91 decimal) needs a $157.13 hedge. Either outcome then nets $42.87.
Prediction-market hedge: futures tickets are often best hedged on Kalshi or Polymarket near settlement. Use the Probability/Prediction-Market format and enter the contract price in cents — the result is exact once converted to decimal.
