How to avoid risks in Sure Betting and Arbitrage Betting
Arbitrage betting removes the normal outcome risk of sports betting when every side of the bet is placed correctly. However, it is not completely risk-free in practice. Moving odds, voided bets, different bookmaker rules, stake limits and human errors can all turn a theoretical sure bet into a loss.
Moving odds
Some bookmakers are faster than others at changing odds and you may end up getting caught in an 'odds trap' where you have placed the bet on bookmaker 1 but the odds have changed at bookmaker 2 leaving you in an unwanted situation with an uncovered bet. How to avoid or mitigate this risk and the other risks listed below, is covered in the Ultimate guide to sure betting
Different bookmaker rules
Bookmakers sometime have different rules for how to handle the outcome in scenarios such as an incomplete game in tennis, over time in ice hockey, etc. This is why it's important to double-check that the rules are the same on all bookmakers to avoid risks in sure betting. RebelBetting only shows arbs between bookmakers that have the same rules, but since bookmakers change rules from time to time it's important that you still double check that the rules are the same before you bet.

Bet cancellation
A bookmaker can cancel a bet claiming it was a palpable error. This can occur when the bookmaker has made an obvious mistake, for instance reversing the odds. The bookmaker has the right to cancel your bet at any time, before, during or after completion of the match, however, bet cancellation is not very common.
Be extra careful with unusually high arbitrage percentages. A very large arb can sometimes be caused by an incorrect price, reversed participants or a mismatched market rather than a genuine pricing difference. Always verify unusually profitable opportunities before placing your bets.
Individual mistakes
To avoid risks in sure betting, we should minimize individual mistakes. An individual mistake is, for instance, betting one side on half time and the other side on full time, betting on the wrong team, not having enough funds on one bookmaker to complete the bet, placing your bet at wrong odds etcetera.
Human errors
Even when the arbitrage itself is mathematically correct, simple human errors can turn a sure bet into a losing position. Common mistakes include betting on the wrong team or player, selecting the wrong handicap line, mixing up full-time and first-half markets, entering the wrong stake or placing a bet after the displayed odds have already changed.
These mistakes are more likely when you are trying to place bets quickly, which is often necessary in arbitrage betting because profitable opportunities can disappear fast. That makes it important to have a consistent routine rather than simply rushing through each bet.
Before confirming a wager, check that the event, market, selection, odds and stake all match the arbitrage you intend to place. Pay particular attention to markets that look similar but settle differently, such as +1.5 versus +1.0 Asian Handicap, match winner versus draw no bet, or regulation time versus overtime included.
Arbitrage software such as RebelBetting can reduce the amount of manual work by finding opportunities and calculating the correct stakes automatically. However, you still place the final bet with the bookmaker, so verify the information before confirming. A few extra seconds of checking can prevent a small input error from becoming a much larger loss.
Dawdling
If you have placed your first bet and then take too long to place the second bet, you may be too late to get the correct odds. However, the risk of dawdling is low when using RebelBetting. When you bet on an arbitrage, RebelBetting automatically logs you into your bookmaker accounts, and many times finds the correct match and highlights the odds. All you have to do is verify the information and place the wager.
Bet limitations
Some bookmakers will limit you sooner or later if you use your betting account solely for arbitrage or value betting. There is no general rule here; people get limited differently quickly by the same bookmakers. Usually, the limitation will occur as a restriction of how much you can bet, but some bookmakers also restrict you by lowering your odds.
Luckily, there are plenty of techniques and strategies that can help you avoid limitations for as long as possible.
Software or service errors
Errors can occur in every software and every service. Using a service such as RebelBetting, you will see that we strive very hard to present accurate information, but sometimes different matches show up in the same arb, for instance, the reserve team and the A-team.
This happens because of the bookmakers inconsistent naming of teams and events. To avoid betting on wrong arbs double check that the teams are playing in the same tournament. It only takes a couple of extra seconds and it's time well spent.
How to overcome these challenges
You can overcome all these challenges if you are committed and willing to invest time in learning the basics. We see it as our mission to help you succeed with both value betting and sure betting.
Most arbitrage betting risks can be reduced with a consistent process: verify the event and market, check both bookmakers' rules, confirm your available stakes, place both sides without unnecessary delay and always review the final odds before confirming your bets. Arbitrage software such as RebelBetting can automate the search and calculations, but you should always verify each wager before placing it. Our blog is full of great tips and tricks for sports bettors.
A simple checklist before placing an arbitrage bet:
- Confirm that both bets cover the same event and market.
- Check bookmaker settlement rules.
- Make sure you have enough balance at both bookmakers.
- Verify that the displayed odds are still available.
- Enter the correct stakes.
- Place both bets without unnecessary delay.
- Confirm that both bets were accepted.

It's taken me less than two months of value betting to make as much as I made from matched betting in a year. View the process as more of an investment than betting, think long-term. Trust the system and keep placing bets.

FAQ: How to avoid risks in sure betting
The most common questions about understanding the risks of sports arbitrage betting.
Is arbitrage betting risk-free?
Arbitrage betting can lock in a profit when all sides of the bet are placed correctly at the required odds. However, the process is not completely risk-free. Odds can change, bets can be rejected or cancelled, bookmaker rules may differ, and human errors can occur when placing the bets.
Using sure betting software such as RebelBetting helps reduce many of these risks by finding and calculating arbitrage opportunities automatically, but you should always verify the odds, markets and stakes before placing a bet.
What is the biggest risk in sports arbitrage betting?
One of the biggest practical risks is placing the first side of an arbitrage and then being unable to place the second side at the expected odds. This can happen because the odds move, the bookmaker changes the maximum stake or the bet is rejected.
To reduce this risk, check that you have enough funds at both bookmakers, verify the available odds and place both sides of the arbitrage without unnecessary delay.
What should I do if the odds change while placing an arbitrage bet?
If the odds change after you have placed the first bet, do not automatically place the second bet using the original stake. Recalculate the arbitrage using the new odds first.
Depending on how much the odds have moved, you may still be able to secure a smaller profit or reduce your potential loss. RebelBetting continuously updates available sure bets, but the final odds should always be confirmed directly at the bookmaker before placing the wager.
Can a bookmaker cancel a sure bet?
Yes. A bookmaker may cancel or void a bet in certain circumstances, for example if the odds were caused by an obvious pricing mistake, often called a palpable error. If one side of an arbitrage is cancelled while the other remains active, the position is no longer risk-free.
This is one reason to be cautious with unusually high arbitrage percentages and always verify that both bets refer to the same event, market and betting rules.
How can I reduce the risks of sure betting?
The best way to reduce sure betting risks is to follow a consistent process: verify both markets and odds, check bookmaker rules, keep sufficient funds across your bookmaker accounts, avoid rushing, and double-check every stake before confirming a bet.
RebelBetting automates much of the searching and calculation involved in sure betting, but successful arbitrage betting still requires careful execution from the bettor.
What should you do if an arbitrage bet goes wrong?
If one side of an arbitrage is rejected, voided or changes significantly, the priority is usually to reduce your exposure rather than preserve the original expected profit. Recalculate the position and look for the best available hedge. Read more in the Ultimate guide to sure betting.
