Calculate guaranteed profit from arbitrage opportunities across bookmakers.
If (1/odds₁) + (1/odds₂) < 1, an arbitrage opportunity exists. The difference from 1 is your profit margin.
Odds of 2.15 and 1.58: (1/2.15) + (1/1.58) = 0.465 + 0.633 = 1.098. Since > 1, no arb. Try 2.15 and 2.10 instead.
Divide your total stake proportionally: Stake₁ = Total × (1/odds₁) ÷ sum. This ensures equal returns regardless of outcome.
Bookmakers actively monitor for arbitrage betting and may limit or close accounts of suspected arbers.
Arbitrage windows are often very short. Odds can change between placing your first and second bet.
Maximum bet amounts vary by bookmaker and market. High stakes on obscure markets can trigger reviews.
