Sure bets

A sure bet (arbitrage) is a market where the best price for every outcome, taken at different bookmakers, adds up to less than 100%. On paper, staking in the right proportions returns the same amount whatever the result. In practice it is not risk-free, because prices move and bets can be voided or limited.

How to read this page
How we find them
We take the best sportsbook price for every outcome of a market and add up the implied chances. Below 100%, the prices cover every result for less than they pay out.
Stake split
Stakes are proportional to each outcome's implied chance, so every leg returns the same amount. Exchanges are left out because of commission.
Why it can go wrong
One leg's price may have moved or may not accept your full stake. If only some legs are placed, you hold an ordinary bet that can lose.
Other risks
Bookmakers can void obvious price errors, settle a market differently from each other, and restrict accounts. Their terms apply to every bet.
