Formula
Arbitrage Check: Sum of (1 / Odds) for all outcomes < 1
Arbitrage Percentage = (1 - Sum of Inverses) × 100%
Individual Stake = Total Stake × (1 / Odds_i) / Sum of Inverses
Guaranteed Profit = Total Stake × Arbitrage Percentage / (1 - Arbitrage Percentage)
Frequently Asked Questions
What exactly is arbitrage betting?
Arbitrage betting, often termed surebetting, consists of staking every possible outcome of an event across separate bookmakers so that a profit is locked in no matter which result occurs. The method draws its value from the discrepancies in pricing that arise between competing bookmakers.
How are arbitrage opportunities identified?
Set the odds offered by several bookmakers for the same event side by side. When the combined total of the inverse odds (1/odds) across all outcomes comes to less than 1, an arbitrage opportunity is present.
Is arbitrage betting permitted by law?
In the majority of jurisdictions arbitrage betting is entirely lawful. That said, bookmakers frequently restrict or shut the accounts of bettors they suspect of arbitrage, since the practice capitalises on the weaknesses in their pricing.
What sort of profit margin is normal for arbitrage?
The bulk of arbitrage opportunities deliver margins in the region of 1-5%. Wider margins do occur but are uncommon, surfacing most often just after odds are first published or when the lines are on the move.
