Arbitrage Finder
Pair odds across different books on opposite sides of a two-way market. When the two prices imply a combined probability under 100%, the calculator splits your stake so both outcomes return the same amount. Everything below is arithmetic on the two prices you type in — it assumes both bets are actually accepted, in full, at exactly those prices.

Combined implied probability: 96.52% — under 100% means the two prices cross.
The figures above are the arithmetic of the two prices you entered. They hold only if both bets are accepted in full at exactly those prices. Prices move, books limit or refuse stakes, and bets get voided — so a pair that crosses on screen is not a completed position, and this calculator is not a projection of any outcome.
