How to Find Value in World Cup Odds: A UK Bettor's Guide

How to Convert World Cup Odds Into Probability

Before you start World Cup betting with value odds at UK bookmakers, the first step you need to take is to learn how to convert World Cup decimal odds into implied probability — if you have not yet chosen a bookmaker, our guide to the best World Cup betting sites covers the top UK options. This simply means converting decimal odds into percentages that show the chances of an outcome.

The simple formula you can use to calculate implied probability of World Cup odds is;

1 ÷ Decimal Odds × 100 = Implied Probability Percentage

Let's look at a few examples of how you can use the formula.

Example 1:

If Team A, let’s say, England, has 2.50 odds of winning a World Cup match against Team B (France), its implied probability is;

1 ÷ 2.50 × 100 = 40. That means England has a 40 chance of winning the match.

Example 2:

On the other hand, if France has 5.00 odds of winning the same World Cup match, it means that the team has a 20 (1 ÷ 5.00 × 100 = 20) chance of beating England.

For UK bettors who prefer betting on the World Cup using fractional odds, here is the formula you can use to calculate implied probability. Remember, you can switch odds format at any time on the bookmaker’s ‘Settings’ or on your profile.

Implied Probability = denominator ÷ (denominator + numerator) x 100

Let’s look at an example;

If a team has odds of 3/1 to win a major World Cup match, its implied probability is 1 ÷ (1+3) × 100, which is 25%.

Once you’ve calculated the implied probability, you should then assess the true probability of an outcome using your own view and opinions. Your assessment should be based on your research on factors such as the team’s recent form, head-to-head records, recent stats, squad depth, and technical analysis.

With both probabilities of an outcome, you can then compare your assessment with the bookmakers' implied probability on an outcome to determine whether there’s any value. But before making your final decision, you should check the bookmaker’s margin (also known as the overround or vig) to make sure your value edge exceeds the margin. Typically, bookies’ built-in margin ensures that the implied probability for all outcomes add up to more than 100, with anything above 100 being profits.

The Bookmaker's Edge and Why It Matters

While finding value in World Cup odds can lead to profitable World Cup betting, keep in mind that it’s very difficult, but not impossible, to find odds with real value. This is because bookmakers have a higher advantage over you since they use professional analysts, data scientists, trading teams, and advanced betting algorithms to come up with odds for each market. This gives them higher efficacy and accuracy when it comes to determining the chance of an outcome. So, trying to find instances where the bookmaker has assigned wrong or inaccurate odds can be time-consuming and difficult.

What’s more, World Cup matches have some of the most efficiently and accurately priced markets in UK football betting. This is because the tournament attracts a huge number of professional betting analysts that makes sure World Cup odds reflect the most accurate probability for outcomes. There’s also extensive media coverage and global betting activity, which makes inaccurate odds less common.

Odds are also influenced by the betting volume. And since almost all World Cup matches attract one of the largest betting volumes across the UK and worldwide, heavy betting on one outcome can cause the odds to shorten across the market. This further reduces the chances of finding significant World Cup value odds.

But that doesn’t mean you can't find value odds when betting on the World Cup at UK bookmakers. It only means they are rare, particularly on major World Cup matches, and you need great research and analysis to identify odds with value. And once you find them, you should bet responsibly, knowing that value odds don’t guarantee long-term profit.

Where Value May Appear in World Cup Markets

Now that you know how value odds work, let’s look at some areas and markets where you’re more likely to find value odds in the World Cup.

Early Outright Markets

Betting on outright markets on teams that you think are underrated by the bookmaker is one of the ways to find value odds in the World Cup tournament. Typically, odds in outright markets shorten as kick-off draws near. So, if a match is several days or weeks before kick-off, uncertainty is at the highest. That means you can place your bets at wider odds if you wager early.

When betting early on outright markets, however, you should be very cautious. This is because early betting is risky as the team’s situation may worsen before the day of the match. For instance, a key player may sustain an injury, lowering the team’s performance, or the team’s form may shift from good to poor.

Less-Followed Nations

You can also assess odds and teams from nations that receive less media coverage in the UK, such as teams in Asia, Africa, and North America. This may give you an edge because UK bookmakers may have less information about the teams’ actual strengths and weaknesses, which can lead to mispricing. The only disadvantage of this World Cup betting strategy is that you also have less info about the teams to base your betting decision on.

In-Play Markets During Fast-Moving Situations

Another great way you can find value in World Cup odds is taking advantage of in-play World Cup betting at UK bookmakers — our World Cup in-play betting guide explains how live markets work and which World Cup markets move fastest during a match. World Cup live odds are updated almost every second as a match progresses in real time, and the odds tend to shift even more rapidly during key moments in the match, like after goals or red cards. During these times, a brief moment of mispricing often occurs, and you can place your bets before the bookmaker adjusts the odds.

While such in-play World Cup betting opportunities may happen frequently throughout the match, the bookmaker may suspend the markets with value odds before you confirm your bets. This is normal, and UK World Cup betting sites usually suspend certain in-play markets as the algorithms recalculate prices.

Markets with More Outcomes

You can also find value odds by analysing World Cup betting markets with many possible outcomes. For instance, you can bet on markets like First Goalscorer and Correct Score as there’s a high chance of mispricing. One disadvantage of this strategy, however, is that markets with more outcomes have wider bookmaker margins, which lowers the amount you can get from your bets.

A Simple Process for Evaluating World Cup Odds

As mentioned, finding value odds when betting on the World Cup at UK bookmakers isn’t easy. But here’s a step-by-step guide on how you can spot value.

Step 1: Before you even look at the odds the bookmaker is offering on an outcome, form your own view on the probability of the outcome. Therefore, do thorough research on the team’s head-to-head record, form, squad depth, and any other factor that may influence the team’s performance. Through your research, you should be able to conclude that a team has a specific chance of winning a certain match.

Step 2: After your independent assessment on the likelihood of an outcome, you should then convert the odds on the bookmaker into implied probability. The formulas to use are ‘1 ÷ decimal odds × 100’ or ‘denominator ÷ (denominator + numerator) x 100’ if you’re using the fractional odds format.

Step 3: You should then compare your independent probability of the outcome with the bookmaker’s implied probability. If your assessed probability is higher than the implied probability, there’s potential value. If not, just skip the bet.

Step 4: If, after comparing the probability in Step 3, you find value, the next step is to consider the reliability of the information you used in your assessment. If it’s trustworthy, you should then place the bet.

Step 5: You should accept that a bet, even with value odds, can either win or lose. Also, keep in mind that World Cup value betting doesn’t guarantee consistent profit, and you need to test your value betting strategy on numerous bets to be sure whether it really works.

What Value Betting Is Not

Many UK bettors often misunderstand value betting, and one of the most common misconceptions is that value betting is the same as backing the underdog. While this is true to some degree, the favourite can also offer value if the bookmaker underestimates the favourite’s probability to win.

Another misconception is that many bettors assume value betting is the same as backing a team that you think will win. Your individual assessment may be wrong or biased, making you bet on a losing outcome, while bookmakers’ odds may offer the actual probability of an outcome, sometimes even overstate it.

Value betting also doesn't guarantee a win, and you can't know with certainty the chances of an outcome occurring — if you are still getting to grips with how odds and markets work in general, our World Cup betting beginners guide covers the fundamentals before you move on to value assessment. In this betting strategy, you only make predictions based on probabilities.

Value Betting and Responsible Gambling

Even with value odds, you can’t escape the bookmaker margin, which guarantees the bookie makes a profit no matter the outcome. Thus, you should bet on World Cup value odds responsibly and with money you can afford to lose. You should also stick to your budget and bet limits, even if you believe you’ve found value odds opportunities in a match. In addition, track your bets honestly, and if your bets lose consecutively, take a break and reevaluate your World Cup value betting strategy.

In case your World Cup betting with value odds stops being fun, or you start having problem gambling, responsible gambling organisations like GamStop and BeGambleAware offer support and counselling. These resources are available for free for all UK bettors, and you can contact the organisations using links or contact details available at the UKGC-licensed bookmaker you’re using.
