Arbitrage with 2 Bookmakers
🎾 What is Arbitrage with 2 Bookmakers?
Arbitrage with 2 Bookmakers is a strategy applied to sports events that have only 2 possible outcomes, such as tennis matches, basketball games, handball, or soccer matches with draw excluded (e.g., "Moneyline" in American bookmakers).
Arbitrage Condition: 1/Odds_BookmakerA + 1/Odds_BookmakerB < 1
⚙️ How Does the Calculation Work?
The formula to calculate the ideal distribution is simple:
Bet Bookmaker A = (Total Stake / Sum of Reciprocals) × (1 / Odds Bookmaker A)
Bet Bookmaker B = (Total Stake / Sum of Reciprocals) × (1 / Odds Bookmaker B)
Where Sum of Reciprocals = 1/Odds_BookmakerA + 1/Odds_BookmakerB. If the result is less than 1, you have guaranteed profit.

💼 Practical Examples
Example 1: Tennis - Grand Slam Final
Wimbledon final between Djokovic and Alcaraz:
- Bookmaker A (Bet365): Djokovic Odds = 2.10
- Bookmaker B (Betfair): Alcaraz Odds = 2.20
Calculation with $100:
- Sum of reciprocals = 1/2.10 + 1/2.20 = 0.4762 + 0.4545 = 0.9307
- Bet Djokovic = (100 / 0.9307) × 0.4762 = $51.16
- Bet Alcaraz = (100 / 0.9307) × 0.4545 = $48.84
- Guaranteed return = $107.44
- Profit = $7.44 (7.44% ROI)
Example 2: NBA Basketball
Game between Lakers and Warriors:
- Bookmaker A (Pinnacle): Lakers Odds = 1.95
- Bookmaker B (Bet365): Warriors Odds = 2.10
Calculation with $200:
- Sum of reciprocals = 1/1.95 + 1/2.10 = 0.5128 + 0.4762 = 0.9890
- Bet Lakers = (200 / 0.9890) × 0.5128 = $103.70
- Bet Warriors = (200 / 0.9890) × 0.4762 = $96.30
- Guaranteed return = $202.22
- Profit = $2.22 (1.11% ROI)
