What is a value bet?
A value bet is a bet where the true probability of an event is higher than the implied probability of the odds offered by the bookmaker. In other words, the bookmaker underestimates the chances of the event.
The formula
EV = (Probability × Odds) - 1
- If EV > 0: the bet has positive value (EV+) — long-term, you make money
- If EV < 0: the bet has negative value (EV-) — long-term, you lose money
