Enter the best odds for each outcome from different books.
Arbitrage betting exploits price differences between sportsbooks to guarantee a profit regardless of the outcome. It works because different books sometimes price the same event differently — one might have Team A at +140 while another has Team B at -120, creating a combined implied probability below 100%.
If the sum of implied probabilities for all outcomes is below 100%, an arb exists. The profit percentage = (1 − sum of implied probabilities) × 100. For example, if outcome A is available at +145 (implied 40.8%) and outcome B at -125 (implied 55.6%), total implied is 96.4%, meaning a 3.6% guaranteed profit on any stake.
Soccer markets have three outcomes: Home, Draw, Away. This creates more arb opportunities because three books can each be the best price on a different outcome. Our calculator handles 3-way markets natively — just select "3-way" and enter odds for all three outcomes. This is essential for EPL, La Liga, Champions League, and Serie A betting.
Arb opportunities are real but come with practical challenges: they disappear fast (often within minutes), require accounts at multiple books, and books may limit or close accounts that consistently arb. Execute immediately once you identify an arb, and always verify odds are still live before placing the second leg. Use the hedge calculator if one leg moves before you can place the other.
