What is value betting and why it matters more than winners

A winning bet is not necessarily a good bet, and a losing bet is not necessarily a bad one. What matters over time is whether you consistently take prices that are bigger than they should be. That is value.

A simple example

Imagine a coin that lands heads exactly half the time. Fair odds would be 2.00. If someone offers you 2.20 on heads, you have value: you will lose some flips, but over hundreds of them you come out ahead. If they offer 1.80, you will lose in the long run even though you still win half the time.

Applying it to sport

Sport is messier than a coin, but the logic is the same. Estimate the true probability of an outcome, convert the odds to an implied probability, and compare. If you think a team wins 55% of the time and the odds of 2.10 imply about 48%, that is value. If the odds are 1.70, implying 59%, it is not, however confident you feel.

Why favourites are often poor value

Popular teams attract a lot of money from casual bettors, and bookmakers shade their prices accordingly. Backing big clubs at short odds can produce plenty of winners and still lose money. Sometimes the value is in the underdog, the draw or a related market such as totals.

How we use this

Every preview on this site shows our probabilities next to the price we are recommending. The bet calculator on each match page also shows the implied probability of the odds. When our number is clearly above the market’s, that is when we are most confident in a pick.

Patience is part of it

Value betting only works over a large number of bets. Short-term results are noisy, so judge any approach, including ours, over hundreds of picks rather than a single weekend.
