How it works

The implied probability is the conversion of odds into a percentage chance of an event happening, as assessed by the bookmaker.

For example, decimal odds of 2.00 imply a 50% chance of success.

If you believe the real-world probability is higher than the implied probability, the bet has positive Expected Value (+EV).
