Kelly Betting

Hello! Welcome – so you’re interested in our Kelly Betting Analysis services, or want to find out more about how it works. Well, you’ve come to the right place.

Quick Summary


In short, in case you haven’t got any idea what’s going on (we’ve all been there …) here’s a quick rundown:

  • We’ve built a machine learning algorithm that predicts the outcome of matches and tournaments in sport worldwide;
  • BASIC: We compare these predictions to the bookmakers odds to look for value; 🔥
  • PREMIUM: We build on the Value Analysis and use the Kelly Criterion to make specific recommendations for how much and where to place your bet. 📈

Premium Analysis and The Kelly Criterion


The Kelly Criterion is a mathematical formula used to determine the optimal size of a bet relative to your total betting pot. It’s widely used in betting and investing because it helps to maximize returns 📈 over time while minimizing the risk 📉 of ruin. The Kelly Criterion calculates the percentage of your pot to stake on a particular bet based on the probability of success and the odds offered.

  • Your betting pot is £100.
  • The bookmaker offers odds of 3.0 (equivalent to a 2 – to – 1 return).
  • You estimate a 60% chance of the bet winning.

This means you should bet 40% of your pot, which is £40.

Our algorithm combines league-specific data and a version of the Kelly Criterion to make tailored recommendations. The percentage you see in each match recommendation is the optimal stake size for that bet, based on:

  • The odds offered by the bookmaker;
  • Our calculated probability of the outcome occurring.

For example:

  • If the recommendation says “Bet 2%,” and your pot is £100, you should bet £2.
  • If it says “Bet 5%,” and your pot is £500, you should bet £25.

You can see exactly how this looks below with the value bets first being identified, and then the specific Kelly % recommendations. 🔥

  1. Maximises Growth: By staking proportionally, it helps you grow your pot faster than flat betting or random betting.
  2. Manages Risk: It ensures you’re never staking too much on any one bet, reducing the chance of wiping out your pot.
  3. Data-Driven Decisions: The criterion forces discipline, ensuring your bets are based on probabilities and value, not emotions

By following these recommendations and the Kelly Criterion, you can take a smarter, calculated approach to betting, optimising your potential returns while managing your risk effectively.

Below shows an example of what the Kelly analysis looks like for a couple of upcoming football matches. This is performed over thousands of matches globally every week. 👇

So - What exactly do I do?


We generally check the website on Thursday evening. By this stage most of the weekend matches will have been priced by the bookies and most of the tips will be up. We generally place bets on the matches on Thursday evenings if available, but there may be one or two missing that we need to recheck on Friday or Saturday. 

However, the more often you check, the more likely you will find better prices, so it’s really up to you how often you check.

What to do?

We check the betting area, specifically using the ‘Show Recommendations’ button in the table. This filter shows all the value bets that have specific Kelly percentage recommendations that exist right now, so it’s easy to see what matches to look at.

We also have Oddschecker (or any other price comparison website) open in another tab to check where the best price is as the odds can - and indeed will! - change so the identified opportunities may not exist if and when you look. We scrape relatively regularly, but it depends on how up to date our sources are. This is where the “Value Thresholds” should be used and you should look for odds over the values suggested for each team.

Try not to worry!

It can feel very irritating when you ‘miss’ a bet and lose out on some potential profits. But try not to think too much about this and end up chasing other bets. In the long run, it won’t matter too much and in some cases you may actually miss out betting on matches that lose! So it will all come out in the wash. You aren’t required to wager every time, so try and stay calm and emotionless about the money you are putting down.
