2. Indeed, arbitrage betting involves betting large amounts of money for a fairly small return. Naturally, you have to cover each outcome for a sporting event to make sure that you have all bases covered. Therefore, the most you can generally make is a 5% return on the money you have laid out.

Arbitrage betting, also known as 'arbing', 'surebets' or 'value bets', is a relatively simple and extremely effective way of making a guaranteed profit by covering all outcomes of an event. For example, in a tennis match there are two possible outcomes. Either Player 1 wins or Player 2 wins. With the right conditions (the odds being favourable), it is possible to make a profit regardless of the result by placing bets on both players.

In this article we'll be taking a look at how it's possible to lock in a profit from these opportunities, how to find them and how to stay under the radar of the bookies who generally aren't too keen on customers placing arbs.

Arbitrage betting isn't something that you should get into if you have no experience of betting. The majority of people who get into arbing have some experience in either trading or matched betting. Despite being a relatively simple concept, it is possible to lose money if you place bets with the wrong stakes or at the wrong odds. Arbing is a logical progression from matched betting as if you've been matched betting for a while, you will understand how odds and betting exchanges work. You may have also been 'gubbed' by certain bookmakers when matched betting which means you are ineligible to qualify for free bets and other promotions and are looking for another way to make a profit from betting. If so, arbing may be the perfect solution for you since it doesn't require the use of any free bets at all.

Arbitrage, or “arbing,” is used in sports betting. Since different bookmakers offer different odds on a given event, a gambler can bet different amounts on all possible outcomes of an event, guaranteeing profit no matter what happens. As an extreme example, if one bookmaker were offering odds of 3-to-1 that a team would win, and another.

Arbitrage betting works by covering all outcomes of an event so that one of your bets wins whatever the result is. There are two ways you can cover all outcomes:

1. Back an outcome with a bookmaker and lay it on a betting exchange
2. Back each outcome with different bookmakers

If you've done matched betting before then you'll be familiar with back and lay bets. It's possible to lock in a profit regardless of the result with this method when the back odds with a bookmaker are greater than the lay odds on the betting exchange.

The example below shows us that 'Spotify' is 5.0 to win the 16:00 Longchamp with Racebets and the lay odds for the same horse on Betfair Exchange are 3.0.

By simply backing this horse at Racebets and laying it on Betfair Exchange, we're able to make a profit whether it wins or not.

To ensure that we make the same profit regardless of the result, we can use an arbing calculator or matched betting calculator to determine the ideal stakes.

As you can see, using a £100 stake with the bookmaker for 'Spotify' to win, if we lay the horse with a stake of £169.49, we will make a profit of £61.02 whether the horse wins or doesn't.

Another arbing method is to only use bookmakers. This can be slightly more time consuming depending on the number of possible outcomes but can be equally profitable.

To keep things simple, let's use a tennis match as an example which has only two possible outcomes.

Below is an example of a profitable arbing opportunity given the odds on each player from two different bookmakers.

If we were to back each player with a single bookmaker, we would end up with a loss. However, if we choose the highest odds from each bookmaker for each player, we are able to lock in a profit.

We need to use an arbing calculator to determine the ideal stakes so that we return the same profit regardless of which player wins the match.

The calculator shows us that using a combined stake (the total stake across the two bets) of £100, if we place a £65 bet on Player 1 to with with Bookmaker A and a £35 bet on Player 2 to win with Bookmaker B, we will make a £4 profit if Player 1 wins and a £5 profit if Player 2 wins.

You can adjust the stakes slightly so that you return exactly the same profit whichever player wins but in this example we have rounded our stakes as recommended by the calculator so that our bets look more natural to a bookmaker. Placing a bet with a stake of £34.67 may raise suspicions that you are arbing and increase the chances of your account being stake limited by the bookmaker at some point.

Finding arbs manually is an extremely difficult process. There may be hundreds if not thousands of sporting events taking place at any one time and tens or hundreds of thousands of markets throughout those events, all with their odds changing frequently. Therefore, the use of some automated software is essential if you want to make sport arbitrage betting profitable based on your time spent doing it. Placing arbs is straight forward and quick but it's the finding them that takes time if done manually.

There are various pieces of arbing software which you can use to find profitable arbs. The costs for these services vary as do the quality of the software but if you choose the right one, the profit you make should more than cover your subscription fee.

If you are mainly searching for back & lay arbing opportunities then a matched betting odds matcher from sites such as ProfitSquad or OddsMonkey may suffice. However, if you want to find the most profitable arbs and arbs where betting exchanges are not required, you should opt for dedicated arbitrage bet finder software. There are many of these about, some of which we have tested ourselves.

Some sport arbitrage betting software which we recommend are:

There are a few things to be aware of when arbing which will minimise the risk of losing money and ensure you're able to return a profit on a long-term basis.

Every now and again you'll come across huge arbs where the odds at one bookmaker are a lot higher than at others. It can be tempting to use these bets to lock in a large amount of profit but be wary of bookmakers miss-pricing bets. It's not uncommon for bookmakers to occasionally make an error when pricing bets and he majority, if not all, will have clauses in their terms and conditions which allow them to void bets which are priced incorrectly due to human error. If you wager on these miss-priced bets and either lay or bet on other outcomes with another bookmaker, you could end up with a loss should your voided bet win.

Use your common sense when determining whether or not the odds are correct. If an arb seems too good to be true, it usually is.

This warning goes for any type of betting whether you are having a punt, matched betting or arbitrage betting. Placing bets with incorrect stakes can cost you money so it is always best to double check your calculations before placing any bets. An arbing calculator will help you determine the correct stakes but it is also useful to understand how stakes are calculated so that you are able to spot obvious errors before it's too late.

It's no secret that bookmakers do not like customers arbing. Arbitrage betting takes advantage of favourable odds at bookmakers and so by placing arbs, you are taking value away from the bookmaker.

Arbing can return high profits on a monthly basis and so to continue to make a profit from arbitrage betting in the long-term, you need to preserve your bookmaker accounts in any way that you can.

The following tips may help you to stay under the bookies radar and mask the fact that you are arbing.

Arbs are available across any sport and market and so it's likely that you'll come across a number of profitable arbs which are on obscure sports which the average punter may not usually bet on.

For example, you may find an arb from which you can make a quick £20 on by covering all outcomes on a Water Polo match in Iceland. However, would you usually bet on Water Polo? Does this bet look natural in the eyes of the bookmaker? If not, then you're at an increase chance of having your account reviewed which could lead to you being stake restricted.

Although we'd recommend staying away from obscure sports and markets, it can be a good idea to look for arbs on sports other than the likes of football or tennis. Lots of arbers jump on these types of arbs as there are usually quite a lot of them about and as there are only 2-3 outcomes, they are very quick and easy to place. Other sports such as boxing and golf are still very popular with punters but less so with arbers. Therefore, your bets are less likely to raise suspicion and you should be able to preserve your accounts for longer.

If you find a profitable arb then it becomes more profitable the more you increase your stakes. However, placing bets dramatically higher than your average stake size with a bookmaker is likely to raise suspicion. Think about the size of your past bets and increase them at a gradual rate rather than jumping from £50 bets to £1,000 bets. By doing so you're a lot more likely to stay under the bookies radar.

Adjusting your bet size depending on the sport and market is also worth considering. If you're average stake on the match result of football matches is £200 then it is unlikely that you would place a £200 bet on a correct score market as these bets usually attract much lower stakes.

Having accounts at multiple bookmakers gives you more options when arbing. Many smaller bookmakers tend to copy the odds from larger bookmakers and so there are plenty of arbing opportunities to take advantage of.

Also, if you get stake restricted or gubbed with a smaller bookmaker you probably won't be as bothered, whereas if you lose one of your main accounts then you could be missing out on betting promotions and offers over time.

does your betting profile look like that of a regular punter?

Overall, you want the bookmakers to think that you are an average punter and not a bet-savvy arber. Take a step back and look at your bet history. Is it full of bets on unusual sports or markets? If so, you may want to think about diluting some of those bets with regular bets so that if a bookmaker does review your account, they're less likely to think that you are only placing bets to take advantage of their odds.

Mug betting is a term which you will be familiar with if you have done matched betting and it involves placing bets with no intention of making a profit. You can still lay these bets and should only make a small loss on each one. By doing so, you should be able to preserve your accounts for a lot longer and continue to make a profit from arbing despite taking a small hit from mug bets.

The basic principle of arbitrage betting is a simple one. The
idea is to place a series of bets on all the possible outcomes
of an event, using a combination of odds and stakes that ensures
you are guaranteed to make a profit regardless of what the
actual outcome is.

You might think this is too good to be true, but arbitrage
betting is a real strategy that does work. In the right
circumstances it is entirely possible to make guaranteed returns
from your bets. It’s not quite as simple as it sounds though.
Many bettors have made the mistake of thinking that this betting
strategy is an easy route to untold riches, but the reality is
that it takes a lot of hard work and patience.

In this article we’ll explore arbitrage betting in more
detail. We’ll explain how it works and why it’s possible, and
also teach you all the calculations you will need to know when using this
strategy. We’ll also look at its advantages and disadvantages,
provide some tips and advice for using this strategy, and answer
some frequently asked questions about arbitrage betting.

It helps to understand the methods that bookmakers use to set their odds
before learning about arbitrage betting. If you’re not familiar with these,
or just want to refresh your memory, please read our article on how bookmakers make money.

How Arbitrage Betting Works

As we’ve already explained, arbitrage betting involves
placing bets on all the possible outcomes of an event in order
to guarantee a profit. In a tennis match, for example, you would
place two bets – one on each player to win. In a soccer match
you would place three bets – one on each team to win plus one on
the draw.

You’re probably already aware that placing such bets with a
single bookmaker would actually guarantee a loss, not a profit.
This is because of the way that bookmakers set the odds to give
themselves a built in profit margin. For a simple example, let’s
imagine there was an upcoming tennis match where a bookmaker
thought both players had an equal chance of winning. They might
set the odds as follows.

A winning $100 bet at odds of 1.91 would return a total of
$191.00, including the initial $100 stake. So if you bet $100 on
each of the two players, you’d be wagering a total of $200 to
get a return of $191.00 regardless of who won. This would
represent a loss of $9.

Arbitrage betting is therefore not as simple as just betting
on all the possible outcomes of an event. If it was that easy,
everyone would be doing it and there wouldn’t be any bookmakers
in business. What you have to do is find opportunities where the
odds with different bookmakers make guaranteed profits a
possibility. Such opportunities are often referred to as arbs.

Using the same hypothetical tennis match as above, it’s
possible that another bookmaker would take a different view on
the likely outcome. They might make Murray the favorite to win,
and set their odds as follows.

This has created an arbitrage opportunity. We’ll show you
some calculations you can use to highlight when an arb exists
later, but please just take our word for it at this stage. You
could make a guaranteed profit by betting on Murray with
“Bookmaker A” and Federer with “Bookmaker B”.

It’s important to note at this stage that you have to work
out the optimal stakes when arbitrage betting. We’ll shortly
show you the necessary calculations for this too, but we’ll keep
it relatively simple for now and use some round figures. The two
bets you would want to make here are $107 on Murray at 1.91 and
$93 on Federer at 2.20, again for a total of $200 of wagered.

As you can see, you would make a profit here regardless of
which player wins. Although this is only a hypothetical example,
it should help you to understand just how arbitrage betting
works. We’ve already mentioned that similar opportunities do
occur for real, and we’ll now explain why.

Why Arbitrage Betting Is Possible

Arbitrage betting is only possible when the right
circumstances present themselves. The odds available on sporting
events regularly vary from one bookmaker to another, but there
needs to be a sufficient difference for an arb to exist. Such a
difference will typically occur for one of the following two
reasons.

• Bookmakers taking differing views on the likely outcome of an
  event.
• Bookmakers adjusting their odds to create a balanced book.

The first reason is the one we referred to in our example
above. Bookmakers tend to set their initial odds based on their
views of what they think will happen in an event, so it is
perfectly possible that two bookmakers will set different odds
if they have different opinions about how an event is likely to
turn out. If their opinions are different enough that there is a
significant disparity in the odds that they offer, then an
arbitrage opportunity may well exist.

Although a bookmaker’s initial odds may reflect their views
about an event, they will subsequently adjust those odds based
on the wagers that they take. If they take a lot of wagers on
one particular outcome, they will almost certainly reduce the
odds on that outcome. At the same time they will increase the
odds on the other outcome (or outcomes). This helps them to
reduce their exposure to risk, and it can also lead to a notable
difference between the odds available at different bookmakers.

There are some other reasons why arbs occur, but the two
mentioned here are easily the most common.

How To Find Arbs

One of the biggest challenges you will face when using an
arbitrage betting strategy is actually finding the right
opportunities. Although they do occur reasonably frequently,
they don’t usually last very long. There are lots of bettors
looking for them so they generally get spotted very quickly. As
soon as a few bets have been placed to take advantage of an arb,
the chances are that the odds will have changed enough for the
opportunity to no longer exist.

You have three primary options when it comes to finding arbs.

There are several websites that advertise arbitrage
opportunities as and when they appear, and some forums where
users can post them up when they identify them. Using such
websites and forums can be a relatively easy way to find arbs,
but there are some downsides.
Firstly, you won’t generally find the most lucrative arbs
this way. People tend to keep those to themselves. You also have
to be quick to take advantage of the ones that you do find. If
there are lots of other people using the same sites and forums,
and there usually are, then the opportunities are likely to
disappear quite quickly.

There is tracking software you can purchase that will find
arbs for you, and alert services you can subscribe to that will
automatically notify you of them. These are relatively easy
options, and very simple to use. You don’t have to do much work
yourself other than place the actual bets. They will cost you
money though, and you may suffer from the same problem of the
opportunities not lasting long.

You’re more likely to win on a slot machine by pulling the lever instead of pressing the spin button.

Also inaccurate. Most slots no longer have a lever on the side. Those that do, however, offer no advantage to the player who chooses it over the spin button. All the winning combinations are being generated internally by the RNG, so it doesn’t matter which method you decide to use.

Calculations Required for Arbitrage Betting

There are two calculations you need to do when arbitrage
betting. The first calculation is simply for determining whether
an opportunity exists, while the second calculation is for
determining the size of the bets you should place. There is also
a third calculation you can use to work out what your overall
profit should be.

Determining Whether an Arb Exists

Please note that this calculation is based on using decimal
odds. If you are working with odds in a different format you can
use our conversion tool to convert them into decimal format. To determine whether an arb exists or not you must first find
the best odds available on each of the possible outcomes of an
event. You must then apply the following calculation to each set
of odds, with the result expressed as a percentage figure. This
result for each set of odds is known as the individual arbitrage
percentage, or IAP.

Using the odds for the hypothetical tennis match we mentioned
earlier, the calculations would therefore be as follows.

You must then add those two IAPs together. Continuing with
the same example, the calculation would be as follows.

Arbitrage Betting Tips

If the result is less than 100% then an arbitrage opportunity
exists. In this case we can see that an opportunity does exist,
as the result is 97.81%. This is referred to as the total
arbitrage percentage, or TAP.

The lower the percentage, the greater the potential profit.
Ideally you want to look for 98% or less, to make the profits
worthwhile, but technically anything below 100% is workable. Any
result of 100% or greater means that there is no arbitrage
opportunity.

Calculating Bet Sizes

As we demonstrated in our earlier example, you have to get
the bet sizes right to make a profit when arbitrage betting. In
order to do this you have to use the following calculation,
where investment is the total sum that you are looking to stake
on the arb.

For our hypothetical match between Murray and Federer,
assuming an investment of $200, the calculations would look like
this.

Placing the two bets using these stakes should guarantee the
same profit, regardless of the outcome. Let’s see if that’s the
case.

There’s a very minor difference of a single cent, but this is
just due to issues with rounding numbers to two decimal places
during the calculations. The important thing to note here is
that you are guaranteed to make a profit of at least $4.47 on
the match.

Calculating Profit

If you want to calculate your expected profit before placing
your wagers, you can use the following calculation.

If we use the same figures as above, the calculation would be
as follows.

As you can see, this is the profit figure we demonstrated
above.

The arbitrage betting strategy clearly relies quite heavily
on math, but you don’t need to be a genius with numbers to make
it work. The calculations required are not particularly complex
and can easily be done on a calculator. It’s just a case of
learning them and knowing when and how to use them.

Advantages & Disadvantages of Arbitrage Betting

There are two main advantages of the arbitrage betting
strategy. The first is simply the very fact that it is possible
to create situations where you are guaranteed to make a profit
on a sporting event regardless of the outcome. It could be
argued that this is not even gambling, as there is no risk
involved once you have created such a situation.

The second advantage is that it’s not really a difficult
strategy to implement. Once you understand the basic principle
of how it works, and the calculations involved, it is relatively
easy to take advantage of any arbs that you manage to find.

However, this strategy is not without its disadvantages. It
might be relatively easy to take advantage of arbs once you find
them, but finding them is not actually that easy at all. There
are lots of bettors out there looking for them, and they don’t
last forever. You need to be quick to spot them, and quick to
act. To make consistent and meaningful profits from arbitrage
betting you will almost certainly need to invest a lot of time
just constantly searching through the betting markets.

You also need to invest a lot of money too. Most arbs offer a
potential return of between 1% and 3% of the total amount
staked, and this means you need a large bankroll to make any
real money.

Let’s assume you were able to find two good arbs a day on
average, each with a return of 2%. You’d probably need to be
betting full time to achieve this, and you’d need to bet a total
of $5,000 on an arb to make $100 from it. That’s $10,000 across
the two opportunities, and you’d want a bankroll of at least
twice that amount. You’d be making $200 a day, but you’d
need a minimum bankroll of $20,000.

That’s a sizable sum of money, and realistically you’d need
even more than that. Another downside of arbitrage betting is
that you need to have accounts with a lot of different
bookmakers, and you need those accounts funded so that you can
place a bet quickly when a particular bookmaker has the right
odds that you need.

It’s also important to note that there are some risks
involved in arbitrage betting. There is no risk once you have
placed the required bets, assuming you’ve done things properly,
but that doesn’t mean the strategy itself is entirely without
risk. There are several things that can go wrong, including the
following.

Taking advantage of an arb requires placing at least two bets
at different bookmakers, and it’s unlikely that you’ll be able
to place multiple bets simultaneously. There is always a chance
that the odds will change after you’ve placed your first bet and
before you’ve placed any subsequent bets, and this can result in
an arb effectively disappearing. This means you have to either
let the first bet run and take the associated risk with that, or
place the subsequent bets anyway and make a small guaranteed
loss.

You have to move quickly when arbitrage betting, and this can
lead to making mistakes. It’s quite possible to make an error
when carrying out the necessary calculations, or even when
placing the required bets. These kinds of mistakes can prove to
be quite costly.

Most bookmakers do not like arbers, and if they suspect you
of being one they may well limit your account or even close it.
With a limited account you may not be able to stake the full
amount you need to make an arb work, and with a closed account
you won’t be able to bet with that bookmaker at all. This can
severely affect your opportunities for arbing.

In some circumstances bookmakers can cancel bets once they
have been struck, and this can be disastrous for you when
arbing. You’ll get your stake back for the cancelled bet, but if
you’ve already placed other bets to take advantage of an arb
then you will be exposed to some risk of them losing without
having the other outcome(s) covered. You may be able to place
the cancelled bet again with another bookmaker, but you may not
get the required odds to recreate the arb.

Arbitrage Betting – Our View

There is no doubt at all that arbitrage betting can be a
profitable sports betting strategy. It is not, however, one that
we can wholeheartedly recommend to everyone. The bankroll
requirements are high and so are the time requirements, and you
will be competing against a lot of well-organized betting
syndicates looking for the same opportunities as you.

We absolutely wouldn’t talk you out of using this strategy,
and if you happen to come across an arbitrage opportunity then
you should always try to take advantage of it. For most bettors,
though, we would suggest that it’s not worth spending too much
time actively looking for arbs. The same time could be better
spent on learning and developing other strategies that may be
more profitable in the long run.

Tips & Advice for Arbitrage Betting

If you do decide to use the arbitrage betting strategy then
the following tips and advice will help you to maximize your
returns.

Stick to events with two possible outcomes

Arbitrage betting gets a lot more complicated when you use
the strategy on events that have more than two possible
outcomes. You’ll miss out on some opportunities if you only look
at events that have just two possible outcomes, but you’ll make
things a lot easier for yourself.

Find your own arbs

Finding arbs can be significantly less time consuming if you
use alert services, tracking software or arbitrage websites and
forums. There is always going to be lots of other people using
them too though, and this means that the arbs that they do
identify are going to disappear very quickly. If you have the
time to spend identifying your own opportunities then you will
probably make more money in the long run.

Always check your calculations

Getting your calculations wrong is the easiest way to lose
money when arbitrage betting. Although you need to move quickly
when you have spotted an arb, taking an extra moment or two to
check your calculations will definitely prove to be time well
spent.

Use a betting exchange were possible

Using betting exchanges can open up a lot more opportunities
for arbitrage betting, due to the fact that you can lay outcomes
as well as back them. Laying and backing makes the strategy a
little more complicated, but can be very profitable.

Keep your betting accounts funded

You’ll need accounts with several bookmakers if you want to
make money out of arbitrage betting, and it’s a very good idea
to keep all your accounts funded. This way you’ll be able to
place any bets required as soon as you highlight an arb, without
having to spend time making deposits.

Form an arbing team

Arbitrage Betting Prediction

There are a number of advantages to arbing as part of a team.
Collectively you will have more time to spend looking for arbs,
and also more money to maximize your potential profits. You will
benefit from having more betting accounts with bookmakers too,
as each member of the team can open accounts in their name. This
should help you to make accounts last longer before they are
limited or closed.

Arbitrage Betting FAQ

Is arbitrage betting legal?

In some parts of the world it is illegal to bet on sports,
which by extension would make arbitrage betting illegal. There
are no specific laws making arbitrage betting illegal though, so
if sports betting is legal where you live then so is arbing.
Bookmakers don’t like it, and take measures to prevent it, but
you’re not breaking the law.

Why don’t bookmakers like arbers?

Bookmakers don’t like arbers because they represent bad
business for them. An arber will always lose a certain
percentage of his bets with a bookmaker, because of betting on
all the possible outcomes, but should make an overall profit in
the long run. The bookmakers are aware of this, and they don’t
want long term winners as customers. If they suspect a customer
of arbing they will limit their account or even close it in
order to protect their own profit margins.

How much money do I need?

There is no fixed amount of money required to use the
arbitrage betting strategy. You can start with just a few
dollars if you want, or you can start with thousands. A bigger
bankroll will mean bigger potential profits, but please only
ever bet with money that you can afford to lose. Arbitrage
betting is a relatively safe way to bet when done properly, but
things can go wrong and you can still lose money.

How much money can I make?

There is no way to accurately answer this question as it
depends on a number of factors. The size of your bankroll, the
number of arbs you can find, and the arbitrage percentage of
those arbs will all affect your overall profitability. As a
general rule you can expect to make returns of between 15% and
25% of your bankroll on a monthly basis, but this assumes that
you have the time and ability to find arbs on a reasonably
regular basis.

What sports can I bet on?

Technically you can bet on any sports using this strategy,
but you’ll find the most arbs on sports where there are only two
possible outcomes. Our opinion is that tennis is the best sport
for arbitrage betting, but others may think differently. You can
find arbing opportunities on US football, darts, snooker,
basketball, and many other sports too.

Can I arb from the United States?

Arbitrage betting is certainly possible from the United
States, but it’s more challenging than it is in many other parts
of the world. This is because US bettors are somewhat limited in
terms of the bookmakers that they have access to, and the
difference in odds between US friendly bookmakers is not
typically that great. This makes it a lot harder to find arbs,
but it’s by no means impossible.
