Betting at odds that are higher than the true probability of the outcome — finding bets where the bookmaker has underestimated the chances of an event.
A value bet exists when the probability of an outcome is higher than the bookmaker's implied probability. If you believe a team has a 55% chance of winning and the bookmaker prices them at 2.10 (implying 47.6%), there is a positive expected value edge on the bet.
Value betting is not about picking winners — it is about finding bets where the price is wrong. Over a large sample, betting consistently at positive expected value generates profit regardless of short-term results.
The process: build your own probability estimate using form, xG, head-to-head records, and context → convert the bookmaker odds to implied probability → compare. If your estimate exceeds the bookmaker's implied probability, there is potential value.
Sharp bookmakers (like Pinnacle) price markets very efficiently with small margins. Their odds are widely used as a reference. If a soft bookmaker prices a team significantly higher than Pinnacle's price, the soft book is potentially offering value.
Implied Probability
The probability of an outcome embedded in bookmaker odds — calculated by dividing 1 by the decimal odds.
Expected Value (EV)
The average outcome of a bet over a large number of repetitions — positive EV means the bet profits long-term; negative EV means it loses.
Kelly Criterion
A mathematical formula that calculates the optimal fraction of your bankroll to stake on a bet, maximising long-term growth given your estimated edge.
CLV (Closing Line Value)
The difference between the odds you backed and the odds at match kick-off — the best long-term predictor of whether your betting strategy has a genuine edge.
Overround (Vig / Juice)
The bookmaker's built-in profit margin — the amount by which the implied probabilities of all outcomes in a market sum to more than 100%.
