What Is Arbitrage Betting?
Arbitrage betting (or "arbing") exploits price differences between bookmakers to guarantee a profit regardless of the outcome. It's one of the few truly risk-free betting strategies.
How Arbitrage Works
When different bookmakers offer different odds on the same event, an opportunity can arise where betting on all outcomes guarantees profit.
Example
Match: Team A vs Team B- Bookmaker 1: Team A at 2.10
- Bookmaker 2: Team B at 2.10
If you bet $100 on each team ($200 total), you're guaranteed to win $210, netting $10 profit regardless of who wins.
Finding Arbitrage Opportunities
Arbitrage opportunities typically arise from:
- Odds movements: One bookmaker is slow to update
- Market differences: Different opinions on probability
- Promotions: Boosted odds that create temporary arbs
The Arbitrage Formula
To check if an arb exists:
1/Odds1 + 1/Odds2 < 1If the sum is less than 1, an arbitrage opportunity exists.
Calculating Stake Distribution
To distribute stakes for equal profit:
Stake on Outcome 1 = (Total Stake × Odds2) / (Odds1 + Odds2)Risks and Considerations
- Account restrictions: Bookmakers may limit or ban winning arbitrage bettors
- Odds changes: Prices can change before you place all bets
- Human error: Mistakes in calculations can turn profit into loss
- Capital requirements: You need substantial bankroll for meaningful returns
- Time investment: Finding and executing arbs requires effort
Is Arbitrage Worth It?
Typical arb margins are 1-3%, meaning you need significant capital for worthwhile profits. It's best suited for:
- Patient bettors with large bankrolls
- Those with accounts at multiple bookmakers
- People who can act quickly on opportunities
