How it works
Find a two-way arbitrage opportunity
Enter the odds for opposite outcomes and a total bankroll. The arbitrage tool calculates the combined implied probability, tells you whether the pair clears break-even, and splits the stake so both winning outcomes return the same amount.
The tool works with prices you supply. It does not scan sportsbooks or retrieve live odds, so confirm both prices directly before placing either side.
Read the arbitrage profit estimate
When reciprocal decimal odds total less than one, the entered prices imply an arbitrage margin. The displayed profit is before account limits, transaction costs, line movement, and settlement differences. If the total is above one, the pair cannot guarantee a positive return at those prices.
Place both sides consistently
Verify the event, market period, selection, and rules on both tickets. Place sizes can be limited or prices can move after the first wager. Recalculate from accepted stakes if either book changes the amount or odds.
Frequently asked questions
Does this arbitrage betting tool scan live odds?
No. Enter the current prices you found at the sportsbooks. The page calculates the stake split and estimated result but has no live odds feed.
What makes an arbitrage profitable?
The implied probabilities of all outcomes add to less than 100%, before execution costs and settlement risk.
How should I split an arbitrage bankroll?
Allocate stakes in proportion to each outcome’s reciprocal decimal odds so the gross return is balanced.
