Value betting

The core idea

A value bet is one where your estimate of the true probability of an outcome exceeds the implied probability in the offered odds by enough to overcome the bookmaker's margin. Over many bets, value betting produces positive expected value.

How to find value

1. Shop odds across multiple bookmakers. The operator with the highest odds on a given outcome has the lowest implied probability. Often this is your simplest source of value.
2. Bet against public bias. Popular teams, star players, and heavily-hyped games carry shaded odds because books balance action rather than set perfect prices.
3. Use statistical models. For football, xG-based models, ELO ratings, and league-adjusted projections beat pure intuition.
4. Act fast on news. Injury and lineup news moves odds. The first 10 minutes after a news break often offer mispriced markets.

Real example

Say you estimate Team A's true win probability at 55%. Operator X offers decimal 2.00 (implied 50%), Operator Y offers 1.91 (implied 52.3%). Your estimate (55%) exceeds both implieds. Expected value calculation:

• At odds 2.00: EV per €100 staked = 0.55 × 100 − 0.45 × 100 = +€10 (10% edge)
• At odds 1.91: EV per €100 staked = 0.55 × 91 − 0.45 × 100 = +€5.05 (5% edge)

Both are value bets. Operator X is the better price.

The hard part

Estimating true probability accurately. Most bettors think they can, but consistent 5%+ edges are rare and require domain expertise or models. If you don't have either, odds-shopping (item #1 above) is the most realistic source of small but real edge.
