Sure Bets - Find the Best Arbitrage Opportunities Today

What Are Sure Bets (Arbitrage Betting)?

Sure bets, which is sometimes referred to as arbitrage betting by those who are familiar with it, see you bet on two different outcomes with different bookmakers. The reason for this is, regardless of the outcome in the markets you have bet on, you will make profit.

The below provides some examples of free sure bets, and if there is any distinction between arbitrage and sure betting.

Example of a Sure Bet Explained

One example of a sure bet could be the over/under market, where you will place a certain amount on the over market, and a certain amount on the under to ensure you make a guaranteed profit with our sure bets today.

This could mean placing a football bet on the over 3.5 goals line at odds of 3.10 with one bookmaker, and under 3.5 goals at 1.62 with a different one. With 65.68 staked, you would receive 106.40 if it was to be under 3.5 goals, and 34.32 staked on over 3.5 goals would return 106.39. This means, regardless of whether there are more or less than 4 goals in the game, you would make a guaranteed profit of at least 6.39% from the 100 that was staked overall.

Arbitrage Bets vs Sure Bets

As you will probably be able to tell from what we have talked about so far, arbitrage bets and sure bets are the same thing. 

Arbitrage relates to the odds where two different online bookmakers have different predictions for the result of the market which has led to them providing different odds, and allows for an arbitrage in the odds.

With the arbitrage odds, you are then able to place sure bets and earn yourself guaranteed profit overall.

To conclude, arbitrage bets and sure bets are the same thing and will both result in the same thing, making you profit without even having to be right about the outcome because you can cover both.

How Do Sure Bets Work?

Sure betting, or arbitrage betting, exploits differences in odds across various betting platforms to make sure the player receives a profit. This is achieved by wagering on two different possible outcomes of any sporting events of your choice.

If one platform were to offer better odds for Team A for basketball betting, and another favours Team B, betting on both outcomes will ensure that you receive a profit. Overall though, the sure betting strategy demands quick decision-making, accuracy, and multiple accounts, as odds can change rapidly.

Why Do Sure Bet Opportunities Occur?

There are several reasons that sure bet opportunities come up, and it is mostly because betting sites follow different models and algorithms, which can lead to discrepancies on occasion between bookmakers.

This is therefore what leads to sure bets on most occasions, but some other factors can also play a part, such as:

• Odds Boosts: Larger discrepancies in the odds may be visible due to promotional prices made available for certain markets, which can lead to sure bets.
• Small vs Larger Bookmakers: Some smaller betting sites may be slower to change their odds, whilst the well-known bookmakers will be sharp in making changes, which can provide the opportunities for sure betting.
• Mistakes: Humanised odds setting can see mistakes made, especially when they are first released, and can lead to arbitrage between different sites.

Advantages and Disadvantages of Sure Betting

Risks and Pitfalls to Avoid

The key thing to avoid with sure bets is it cannot be your only way of placing wagers, because it will be much easier to flag for operators.

If you are a regular bettor who sometimes partakes in placing sure bets, betting sites are less likely to take action, compared to somebody who is making a steady stream of earnings from placing them consistently.

Profit Potential with Sure Bets

The idea of sure betting is to secure profit without a doubt, which is why it is such a popular way of wagering for many users on our site and throughout the betting space. It is important to be aware that the money to be made, although “sure”, is not always significant.

How Much Money Can I Make?

The money made from sure bets is not particularly large, but it will mainly depend on the amount you are staking on the bets.

However, the more you stake, the more you risk bookmakers taking notice of your arbitrage betting and potentially closing down your account with the chosen betting site.

The amount of money to be made can be worked out through our sure bets calculator available on this page, demonstrating the amount of profit you stand to make from your bets.

Is Sure Betting Still Profitable in 2025?

Sure betting is a style of wagering that leads to definite profitability because you are guaranteed to receive more than the money you placed. Unlike other recommended ways of betting on our site, like value bets or dropping odds, sure bets are designed to earn you profit without a doubt.

As already mentioned, the money returned may not always be a lot, but it is a profitable way of placing bets with sportsbooks.

Is Sure Betting Legal and Safe?

Sure betting is completely legal and safe, but can come with some consequences, especially if you are found to be doing it on a regular basis. In some cases, bookmakers don’t take too kindly to sure bets, so it is important to be aware of what may happen, including limitations on your account or closure.

Can I Get Caught Arbing?

As already touched on, bookmakers can find your account to be arbing and decide that they no longer want you to use their platform.

They will typically have crawlers or softwares that analyse competitor pricing to flag where arbing may have been taken advantage of by a user.

Not everyone is caught arbing, but it is definitely a risk that comes with sure bets.

What Bookmakers Think About Sure Bets

All bookmakers will have different feelings towards sure bets and different ways of dealing with it how they see fit. However, the general consensus is that they are not particularly supportive of them, demonstrating the riskiness of partaking in the activity.

Due to the nature of the bets and it leading to sure wins, it is not something that bookmakers are fond of players doing because it means they lose money.

Sure Bets - FAQs

What Is An Example Of A Sure Bet?

There are many examples of sure bets, but the best is probably on the over/under market, where you could bet for example over 2.5 goals with one bookmaker, and under 2.5 goals with another due to the arbitrage odds.

Say for instance that over 2.5 goals in a game was 2.45 and under 2.5 goals was 1.87 and you wanted to risk 200 overall, you would place the bets in the way it is shown below:

86.57 stake on over 2.5 goals at 2.45 = 212.10 returns

113.43 stake on under 2.5 goals at 2.45 = 212.11 returns

By betting in this way, you are guaranteed to make 12.10 or 12.11 profit whether the match is over 2.5 goals or under 2.5 goals thanks to arbitrage odds.

How Do I Choose Sure Bets?

The best way to choose your sure bets would be to pick the options which have the highest amount of profit for you to make. There are no limits to the amount of sure bets that you can place either, provided you are registered with the recommended online bookmakers that the arbitrage odds are available with.

If you are interested in watching the match that you have decided to place a sure bet on, it might be worth choosing one that is of more interest to you, for example if you prefer football over other sports.

How Do You Make Money with Sure Bets?

The way you make money with sure bets is by regularly placing them. By placing one sure bet you will make a profit, but it’s only likely to be a small margin. However, by regularly taking advantage of sure bets we recommend, you will make a larger amount of profit over time.

Is Sure Betting Legal?

Sure betting is completely legal, because you are simply placing bets at the odds provided by online bookmakers in your location.

One thing to be wary of is that online betting sites do have the power to restrict your stakes, and by placing these bets regularly they might take notice and put things in place to stop you from placing wagers on sure odds.
