⚽ Football Odds

Arbitrage betting (also called "sure betting") is a strategy where you bet on all possible outcomes of a sporting event across different bookmakers to guarantee a profit regardless of the result.

ROI is calculated using the formula: (1 − (1/O₁ + 1/O₂ + 1/O₃)) × 100. It represents your fixed return for every $100 total wagered across the three outcomes.

The mathematical opportunity is real, but speed is key. Odds change constantly. Treat these as indicative and always verify the odds on the bookmaker's site before placing bets.

1. Find a match with an "Arb Found" indicator.
2. Note the three outcomes and their best available odds.
3. Use the calculator: enter your total investment to get the exact stake for each bookie.
4. Place all bets simultaneously to lock in your profit.

• Stale odds: Odds may change while you are placing the different legs of the bet.
• Account limits: Bookmakers may detect and limit "sharp" bettors.
• Human error: Placing the wrong stake or outcome creates a potential loss.

ROIs above 5% are often caused by data artifacts—errors in a bookie's feed. Legitimate arbs in EU markets usually range from 0.5% to 3%.
