Betting Arbitrage – The Strategy That Always Wins

Perhaps you have heard of betting arbitrage or also called sure bets or arbs,perhaps you haven’t. Betting arbitrage is a type of strategy that involves placing bets on two or three bookmakers, where the coefficients differ is such way that you win no matter what the outcome of the game is.Your winnings will be relatively small around 1-5%, which means on every 100$ you place, the return will be 1$-5$. How’s that possible one might ask? Well usually it’s either the different calculations of the bookmakers or just a calculation error. So let’s get in details to see how the whole system works.


Let’s say you have Team A and Team B and the following odds are given to you:


Team A win – 3.75


A Draw       – 3.40


Team B win – 1.80


In order for you to win, no matter what the outcome of the game is, the sum of the above odds to the power of -1 has to be less than 1. In simple words every number to the power of -1 is a fraction,so the calculation:


1/3.75 + 1/3.40 + 1/1.80 has to be less than one;


However bookies always have a 7-15% profit and most of the time the sum will be anywhere from 1.07 to 1.15. In our example it is .27 + .29 + .56 = 1.12 – the bookmaker’s profit is 12%. Now let’s say that those are the odds for bookmaker 1, but bookmaker 2 is giving out an odd for Team B to win of 2.50. You calculation then would be .27 + .29 + .40 = .96 which results in 4% profit or for every 100$ you place you would get back 4$.


Now you will have to calculate how much exactly to place on each outcome. This is done by the formula:


1 / odd * return % (in our example 100% + 4% or 1.04) * the total amount you plan to place (in our example 100$);


So 1/3.75 * 1.04 * 100 = 28.08$ on Team A to win 1/3.40 * 1.04 * 100 = 30.16$ on a draw and 1/2.50 * 1.04 * 100  = 41.60$ . Due to our rounding we might be off with some cents.


To summarize you will need to place 28.08$ on Team A , 30.16$ on a draw and 41.60$ on Team B in order to win 4$ no matter what happens in the game. As you may notice the profit isn’t much, and that is why sure bets are played usually with large amount of money.


You can also bet on Back – Lay sure bets where you have only two odds and it’s easier to calculate. Those for example are the soccer under/over goals, basketball point spreads and etc. The calculations are exactly the same, but this time you have only two odds to sum up and it’s just easier.


So what’s the catch? Why isn’t everyone doing this? Well first off it’s extremely hard to find such games, if not impossible. A lot of sites on the Internet claim to have such games and give you real time calculations and tips, believe me I’ve checked them out most of the games given out are wrong, since the odds are entered manually by the users or the bookmakers have updated already the odds.


Second this type of betting, as we mentioned requires a lot of cash, so if you are not ready to take out at least 10,000$ do not expect big profits.


And last be not least, the bookmaker has the right to cancel your bet at any time, if they find out that they have made a calculation mistake. This means that you might end up loosing a large sum of money,so there’s a risk in this strategy as well.


It’s really up to you, the reader you if you want to try out the betting arbitrage calculator, depending on your goals this might be the strategy for you.

  1. Good post. They actually have a software ’100 percent winners’ that Shows games from bookings around the world and the arbitrage percent for it. Do you know of this software? its pretty good I see that its all over this website so I guess maybe u already know. But you have to choose the bets quick before someone else takes them. However u dont really need much money to start. u can start with 100$ like i Did. So lets say that I placed 100$ on 2 betters with an arbitrage of 10%? Once the game is over ill get $110. You can’t loose. Unless the booking is canceled or what ever.

    Anyway good post man!
