How It Works

🎯 What is a Surebet?

A surebet (or arbitrage bet) is a betting strategy that guarantees profit by exploiting differences in odds across multiple bookmakers. By betting on all possible outcomes, you ensure a profit regardless of the result.

Example: Bookmaker A offers 2.10 for Team X to win, while Bookmaker B offers 2.10 for Team Y to win. By betting on both, you guarantee profit.

📊 How to Identify Surebets

A surebet exists when the sum of the inverse odds is less than 1:

(1 / Odds1) + (1 / Odds2) < 1.00

Example: Odds of 2.15 and 2.15 → (1/2.15) + (1/2.15) = 0.93 → Surebet! ✅

💰 Stake Calculation

The calculator distributes your total stake proportionally to guarantee equal profit on all outcomes:

Stake = (Total Stake / Sum of Inverse Odds) × (1 / Individual Odds)

⚠️ Important Considerations

  • Quick execution: Odds can change rapidly. Place all bets as quickly as possible.
  • Account limits: Bookmakers may limit your account if they detect arbitrage betting.
  • Rounding: Round your stakes appropriately. The calculator shows 2 decimal places.
  • Commissions: Factor in any exchange commissions or fees when calculating.
