Surebet: Risk-Free Strategy or Scam?
What is a surebet?
A surebet (or arbitrage betting) is a sports betting technique that guarantees a mathematical profit, regardless of the match outcome. This strategy exploits the differences in odds between multiple bookmakers to create a situation where all possible outcomes generate a profit.
But does this promise of risk-free gains hide pitfalls? Let’s analyze this controversial strategy in detail.
How does a surebet work?
<img src=”exemple-calcul-surebet-tennis.jpg” alt=”Example of surebet calculation on a tennis match” title=”How a surebet works between two bookmakers” width=”800″ height=”450″ />
The mathematical principle
A surebet exists when the sum of inverse probabilities is less than 100%:
Formula: 1/Odds1 + 1/Odds2 + 1/Odds3 < 1
Concrete example
Tennis match Nadal vs Djokovic:
- Bookmaker A: Nadal 2.20 / Djokovic 1.80
- Bookmaker B: Nadal 1.90 / Djokovic 2.10
- Best odds for Nadal: 2.20 (Bookmaker A)
- Best odds for Djokovic: 2.10 (Bookmaker B)
- Verification: 1/2.20 + 1/2.10 = 0.454 + 0.476 = 0.93
0.93 < 1 = Surebet detected!
Calculating optimal stakes
For a capital of €1000:
- Stake on Nadal: €1000 × 0.476 = €476 at Bookmaker A
- Stake on Djokovic: €1000 × 0.454 = €454 at Bookmaker B
Guaranteed profits:
- If Nadal wins: €476 × 2.20 = €1047
- If Djokovic wins: €454 × 2.10 = €953
Total stake: €930 Guaranteed profit: €23 to €117 depending on the result

1. Pre-match surebet
The most common, based on odds before the match starts:
- Lifespan: Usually 5-30 minutes
- Average profit: 1-3%
- Difficulty: Medium
2. Live surebet
Exploiting delays during the match:
- Lifespan: A few seconds
- Average profit: 3-8%
- Difficulty: Very high
3. Surebet middles
Betting on a “window” of results:
- Example: Over 2.5 goals + Under 3.5 goals
- Profit if: Exactly 3 goals
- Risk: Partial loss possible
Why do surebets exist?
1. Time delays
Bookmakers don’t adjust their odds simultaneously, creating opportunity windows for surebets.
2. Different opinions
Each bookmaker has its own analysts and models, generating different evaluations.
3. Commercial strategies
Some bookmakers deliberately offer attractive odds to attract new customers.
4. Human errors
Sometimes, a trader makes a mistake in their odds, creating a temporary surebet.
