What Is Arbitrage Betting?
Arbitrage betting (also called “sure bets” or “arbs”) is a strategy where you place bets on all possible outcomes of an event using different bookmakers.
The goal is to lock in a potential profit by taking advantage of differences in bookmaker odds. This is only possible when all bets are successfully placed at the quoted odds before the market changes.
How It Works
- Different bookmakers offer different odds
- You bet on all outcomes at the best available odds
- If the total implied probability is less than 100%, you have an arbitrage opportunity
Before placing any arbitrage bets, compare odds carefully across multiple bookmakers. You can also explore our Betting Tools & Resources Guide for additional calculators and resources that can help improve your betting analysis.
Arbitrage Formula (Simple Explanation)
To check if a sure bet exists:
(1 / Odds1) + (1 / Odds2) + (1 / Odds3) < 1
If the result is below 1 → ✅ Guaranteed profit
If you’re new to implied probability and value betting, our Betting Strategy Guide explains these concepts in more detail.
