Value Betting Sports
Value betting is an essential skill for bettors. What is a value bet? How can a bettor find value? Read on to find out.
The easiest way to make money on sports. With value betting, you place bets that have a larger chance of winning than implied by the odds, giving you the edge over the bookmakers. Expected Value (EV) is the most simple of all betting equations: Expected Value is the predicted value of a variable, calculated as the sum of all possible values each multiplied by the probability of its.
One of the most interesting things about betting is that nobody knows the true probability of the outcome of an event (other than a coin toss). Bookmakers set odds based on their assumptions and the state of the market. A value bettor will attempt to capitalise on the probabilities implied by odds they believe to be incorrect.
What is a value bet?
In order to find value a bettor needs to determine their own probability of an event occurring. In simple terms, if a bettor is able to correctly identify events where the probability of the event occurring is higher than that implied by the bookmaker’s odds then they will win in the long run.
Bet offers value when:
probability of outcome > probability implied by odds
Example of a value bet
Let’s use the example of a fair coin toss. Ignoring the chance the coin lands on its side we know that the chance of a head is 50%. This implies fair odds of 2.00. Once the bookmaker adds their margin the odds could be (depending upon the bookmaker) around 1.91 implying a 52.4% chance of the toss resulting in heads.
We know that this bet offers poor value since we are receiving odds on a 50% likelihood as if there was a 52.4% chance of heads.
Now imagine there is some uncertainty as to the percentage chance of heads. We have calculated that the chance of heads is 50% but the market is uncertain. The bookmaker is now offering odds of 2.2 on heads.
This now offers the opportunity to take a bet with 50% odds as if the event had only a 45.5% chance of occurring. This is a value bet.
We can determine the profitability of a bet by using the expected value formula:
So with our coin toss example the expected value calculation from a €10 stake is:
For each €10 bet the expected return is €11 (a profit of €1).
For each coin flip we can expect to win €11 for every €10 staked. This would become very lucrative in the long run.
How to find value bets
A good way to find value bets is to look at differences in bookmaker odds. Where bookmakers disagree about the chance of an event occurring may be where value is present.
Building a superior model or taking advantage of information asymmetry can also be a good way to find value. If a model or inside information gives the bettor a clearer grasp of true probability than the bookmaker then profits are available.
The importance of the long run
When value betting it is important to bet for the long-term. Even with the clear edge on the coin toss at 2.2 odds there is still a 50% chance that the bettor loses. This is when a staking strategy becomes important as bankrolls can be decimated by over staking, even on bets that offer value.
In the long run this strategy pays off. After 100 coin flips staking €10 the bettor would expect to have €1100 from the €1000 wagered.
In a similar way, if a sports bettor can find enough value bets they will win in the long run.

The importance of odds
Value is all about finding the best odds and no bookmaker offers better value than Pinnacle. If bettors take lower odds from elsewhere then a value betting strategy becomes less profitable or even loss-making.

Some bookmakers ban winners, making a long-term value betting strategy impossible. Pinnacle operate a winners welcome policy so value bettors can make the most from their edge.
