What is value betting?

Most bettors pick who they think will win. Value bettors do something different: they ask whether the odds are bigger than they should be. That gap between the true chance of an outcome and the price the bookmaker offers is where profit lives.

Every set of odds contains an implied probability. Decimal odds of 2.00 imply a 50% chance. If you believe the real chance is higher than 50%, the bet has value, regardless of whether it wins this time. Over hundreds of bets, backing value is what turns betting from luck into an edge.

Odds and implied probability

To find value, first convert odds into a probability. The formula is simple:

Once you can read the probability behind any price, you can compare it against your own estimate of how likely the outcome really is.

A worked example

Say a bookmaker prices a team to win at 2.50. That implies a 40% chance (1 ÷ 2.50). After your own analysis of form, xG and team news, you believe the team actually has a 50% chance of winning.

Your estimate (50%) is higher than the implied probability (40%), so the odds are bigger than they should be. That is a value bet, even though the team is far from certain to win.

How to find value bets

Value betting dos and don’ts

Do

• Judge every bet on price, not just on who you think will win
• Keep records so you can see whether your estimates beat the market
• Stake consistently and think in terms of hundreds of bets, not one

Don’t

• Back short-priced favourites just because they will “probably win”
• Chase losses by increasing stakes after a losing run
• Confuse a winning bet with a good bet, or a losing bet with a bad one
