For bettors seeking guaranteed profits, arbitrage betting—also known as arbing—seems like a dream strategy. The concept is simple: by placing bets on all possible outcomes of a sporting event using different sportsbooks, you can lock in a risk-free profit no matter the result. But while the theory is sound, the execution comes with risks, limitations, and red flags.
Here’s how arbitrage betting really works, what you need to succeed, and why it may not be as effortless as it sounds.
What Is Arbitrage Betting?
Arbitrage betting involves taking advantage of discrepancies in odds between two or more bookmakers. These differences allow you to place bets on all outcomes of an event and guarantee a small, consistent profit.
Example:
In a tennis match:
- Bookmaker A offers Player 1 at 2.10 (decimal odds)
- Bookmaker B offers Player 2 at 2.10
By betting on both players in the correct proportions, you guarantee a profit no matter who wins.
How It Works:
- Calculate the implied probabilities of all outcomes using the odds.
- If the combined probability is less than 100%, it’s a viable arbitrage.
- Allocate your stake proportionally to guarantee a return.
Pro tip: Arbs usually return 1–3% profit per event, so high volume and speed are key.
Tools You Need for Arbing
Arbitrage betting requires precision and timing. Successful arbers often rely on:
- Arbitrage betting software (e.g., RebelBetting, BetBurger, OddsJam)
- Multiple bookmaker accounts
- Fast internet access
- A calculator or spreadsheet for stake sizing
You also need to understand how to avoid detection, since many bookmakers frown on arbing and may restrict or close your account.
The Benefits of Arbitrage Betting
- ✅ Guaranteed profit if executed correctly
- ✅ Doesn’t rely on predicting outcomes
- ✅ No emotional decision-making—pure math
- ✅ Can work across sports, markets, and regions
For sharp bettors willing to put in the effort, arbing can be a low-risk way to grow a bankroll steadily.
Risks and Drawbacks of Arbitrage Betting
Despite its appeal, arbitrage betting comes with several challenges:
1. Bookmaker Limitations
Many sportsbooks monitor for arbing behavior:
- Limiting bet sizes
- Voiding bets
- Closing or suspending accounts
- Delaying withdrawals
If you’re flagged as an arber, your options will quickly shrink.
2. Odds Change Quickly
Arbs don’t last long. A line can shift within seconds, closing the window for a guaranteed profit. If one bet is placed and the second odds move, you may be exposed to risk.
3. Stake Errors and Calculation Mistakes
One small mistake in odds conversion or stake sizing can eliminate profit or create a loss. You need to:
- Double-check calculations
- Account for commission on exchanges (if used)
- Be accurate under time pressure
4. Bet Cancellation or Market Rules
Bookmakers may void bets due to:
- Palpable errors (bad odds)
- Event cancellation
- Rule differences between platforms (e.g., in tennis retirements)
These scenarios can destroy an arb position and leave you vulnerable.
Is Arbitrage Betting Worth It?
Arbing can work for:
- Highly disciplined bettors
- Those with access to multiple sportsbooks
- People comfortable with spreadsheets, fast action, and limited emotional reward
But it’s not passive income or an easy path to riches. It demands time, attention, and risk management. Many casual bettors find the returns too small or the lifestyle too intense.
If you’re looking for more sustainable, long-term profits, strategies like value betting, line shopping, or matched bettingmay offer better balance with less stress.
Final Thoughts: Profitable—But Not Effortless
Arbitrage betting is a legitimate method for squeezing out profit from the sportsbook ecosystem, but it’s not without challenges. Between limited opportunities, account restrictions, and the constant need for speed and accuracy, it’s a high-effort strategy best suited for dedicated bettors.
If you’re prepared to play the long game and work around the hurdles, arbing can be a valuable tool in your sports betting arsenal—but go in with eyes wide open.
