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 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.
