What is 7-Way Arbitrage?
7-Way Arbitrage is an advanced betting strategy where a bettor places wagers on all seven possible outcomes in a market, ensuring a guaranteed profit no matter which result occurs. This type of arbitrage is typically found in specialized sports betting markets with multiple outcomes, such as exact scores or niche events where several results are possible.
How Does 7-Way Arbitrage Work?
The principle behind 7-Way Arbitrage is the same as other arbitrage strategies:
(1 / Odds 1) + (1 / Odds 2) + (1 / Odds 3) + (1 / Odds 4) + (1 / Odds 5) + (1 / Odds 6) + (1 / Odds 7) < 1
If the sum of the inverse of all odds is less than 1, an arbitrage opportunity exists. This allows you to place bets on all seven possible outcomes and guarantee a profit.
Example Calculation
Imagine a match with seven possible outcomes. The odds for each outcome are:
- Outcome 1 → 4.50
- Outcome 2 → 5.00
- Outcome 3 → 5.50
- Outcome 4 → 6.00
- Outcome 5 → 6.50
- Outcome 6 → 7.00
- Outcome 7 → 7.50
Step 1: Check for Arbitrage
(1 / 4.50) + (1 / 5.00) + (1 / 5.50) + (1 / 6.00) + (1 / 6.50) + (1 / 7.00) + (1 / 7.50) = 0.986 → Arbitrage exists.
Step 2: Calculate Stakes (for a $100 total bet)
- Outcome 1: $22.22
- Outcome 2: $20.00
- Outcome 3: $18.18
- Outcome 4: $16.67
- Outcome 5: $15.38
- Outcome 6: $14.29
- Outcome 7: $13.33
Step 3: Calculate Profit
- Any outcome will result in a return of about $102-$103, ensuring a $2-$3 profit.
