How Arbitrage Works

Sports betting arbitrage exploits differences in bookmakers' odds. When the combined implied probability of all outcomes is less than 100%, a potential profit is possible. If the sum of implied probabilities < 1, an arbitrage opportunity exists.

The larger the difference between the sum of implied probabilities and 1, the greater your potential profit margin on the arbitrage opportunity.

In English: If two bookmakers have significantly different odds for the same event, you can strategically bet on both sides and aim for a profit — no matter the outcome.

Odds & Allocation

Positive Odds (+110):

Prob = 100 / (odds + 100)

Negative Odds (−110):

Prob = |odds| / (|odds| + 100)

Stake A:

Stake A = Total × (Prob A / Total Prob)

Stake B:

Stake B = Total × (Prob B / Total Prob)
