Comment ça marche
An arbitrage (surebet) exists when the best odds on every outcome, taken from different bookmakers, make the inverse odds add up to less than 1. Backing every outcome in the right proportions then returns more than you staked whatever happens.
Enter the best decimal odds you found for each outcome and your total stake. The tool shows whether there is a surebet, how much to stake on each outcome, the equal payout and the locked-in profit.
Questions fréquentes
How do I know if odds form an arbitrage?
Add 1 / odds for every outcome. If the total is below 1 there is a surebet. Odds of 2.10 on both sides give 0.476 + 0.476 = 0.952, a profit of about 5%.
How should the stake be split?
Proportionally to the inverse odds, so every outcome pays the same amount. The calculator does this for you.
Are surebets risk free in practice?
Not always. Odds move, bets can be limited or voided, and different rules (such as dead heat or overtime) can break the hedge. Check the rules of each bookmaker.
