What is a surebet?

A surebet (also called an arb) is a set of wagers on every possible outcome of an event at odds that guarantee profit no matter what happens. You are not predicting the result. You are exploiting a pricing mistake across one or more bookmakers.

If the combined implied probability of all outcomes is less than 100%, a surebet exists. The gap is your margin.

Implied probability

Decimal odds convert to implied probability: 1 ÷ odds × 100. Add every outcome. Under 100% means surebet.

Implied % = (1 / decimal odds) × 100 · Surebet when sum < 100%

The screenshots show a real example: Mandurah Magic (W) vs Joondalup Wolves (W). Away at 6.50 on Nairabet is 15.4%, Home at 1.23 on BetKing is 81.3%. Combined 96.6%, so 3.43% profit. Hit Calc in the list to get the stake split on your bankroll.

Surebets vs value bets

A surebet removes outcome risk entirely if all legs land at the quoted prices. A value bet is different: you bet one side because the odds beat your estimate of true probability, but you can still lose individual bets. Value betting wins over hundreds of bets. Surebetting wins on every correctly executed arb.

You need all three legs. If Home is 2.20 on one site, Draw 3.50 on another and Away 3.80 on a third, add the three implied probabilities. Under 100% means a surebet. Sportalon's finder calculates the exact stake split for your bankroll.
