Complete Arbitrage Guide
🎯 What is Arbitrage (Surebet)?
Sports betting arbitrage (also known as Surebet) is a strategy that allows you to guarantee profit regardless of the outcome of a sports event. This happens when you find odds at different bookmakers whose sum of reciprocals is less than 1.
Arbitrage Condition: 1/Odds₁ + 1/Odds₂ + ... + 1/Oddsₙ < 1
⚙️ How Does Arbitrage Work?
Arbitrage exploits differences in odds between different bookmakers. When two or more bookmakers have very different opinions about an event, an arbitrage opportunity arises.
Identify the opportunity
Find odds at different bookmakers whose sum of reciprocals is less than 1
Calculate the distribution
Use the formula to know how much to bet on each outcome
Execute the bets
Bet the calculated amounts at each bookmaker
Guarantee the profit
Regardless of the outcome, your return will be greater than the amount invested
📐 The Arbitrage Formula
The formula to calculate arbitrage is simple and direct:
Sum of reciprocals = 1/Odds₁ + 1/Odds₂ + ... + 1/Oddsₙ
If the result is LESS than 1, you have an arbitrage opportunity. The smaller the value, the greater the guaranteed profit.
Guaranteed profit = (1 / Sum of reciprocals - 1) × 100%
📊 Detailed example:
Odds: 2.10 and 2.20
- Sum of reciprocals = 1/2.10 + 1/2.20 = 0.4762 + 0.4545 = 0.9307
- Guaranteed profit = (1 / 0.9307 - 1) × 100% = 7.44%
- With $100 staked, profit = $7.44
📊 Types of Arbitrage
Pre-Match Arbitrage
Opportunities identified before the event starts. Generally have lower ROI (1-5%) but are more stable.
Live Arbitrage
Opportunities during the event when odds fluctuate rapidly. ROI can reach 10-20% but last seconds.
Multiple Arbitrage
Involves 3 or more outcomes (e.g., soccer 1X2). Rarer, but can offer good opportunities.

💼 Practical Arbitrage Examples
Example 1: Tennis (2 outcomes)
In a tennis match between Djokovic and Alcaraz:
- Bookmaker A: Djokovic Odds = 2.10
- Bookmaker B: Alcaraz Odds = 2.20
Calculation with $100:
- Sum of reciprocals = 0.4762 + 0.4545 = 0.9307
- Bet Djokovic = $51.16
- Bet Alcaraz = $48.84
- Guaranteed return = $107.44
- Profit = $7.44 (7.44% ROI)
Example 2: Soccer (3 outcomes)
In a soccer match:
- Bookmaker A: Team A Odds = 2.50
- Bookmaker B: Draw Odds = 3.40
- Bookmaker C: Team B Odds = 3.80
Calculation with $200:
- Sum of reciprocals = 0.4000 + 0.2941 + 0.2632 = 0.9573
- Bet Team A = $83.56
- Bet Draw = $61.44
- Bet Team B = $55.00
- Guaranteed return = $208.90
- Profit = $8.90 (4.45% ROI)
Example 3: Basketball (Handicap)
In a basketball match with handicap:
- Bookmaker A: Handicap -5.5 Team A = 1.95
- Bookmaker B: Handicap +5.5 Team B = 2.05
Calculation with $100:
- Sum of reciprocals = 0.5128 + 0.4878 = 1.0006
- Not arbitrage (sum > 1)
- Guaranteed loss of 0.06%
