What is the Arbitrage Calculator?
When two books disagree enough that the implied probabilities of the two sides sum to under 100%, betting both sides guarantees a profit no matter the outcome. This calculator sizes the second bet so you win the same amount either way.
How to use it
1.Enter the odds on each side (from the two different books).
2.Enter either bet size — the calculator solves the other side.
3.The profit shown is locked in whichever side wins.
Example
+120 at one book and -110 at another: bet $100 on the +120 side and $115 on the -110 side, and you profit about $5 no matter what happens. Our Arbitrage tool finds these opportunities live.
