Arbitrage Betting Guide: How to Guarantee Profit

Arbitrage betting (arbing) is a strategy that exploits odds differences between bookmakers to guarantee profit regardless of the outcome. This guide explains everything you need to know.

What is Arbitrage Betting?

Arbitrage occurs when the combined implied probability of all outcomes is less than 100%. This means you can bet on all outcomes across different bookmakers and guarantee a profit.

The Basic Concept

When bookmakers disagree on probabilities, opportunities arise:

• Bookmaker A: Team X to win at 2.10 (47.6% implied)
• Bookmaker B: Team Y to win at 2.10 (47.6% implied)
• Combined: 95.2% — 4.8% guaranteed profit

How to Calculate Arbitrage

Step 1: Check for Arbitrage

Formula: (1/Odds1 + 1/Odds2) × 100

If result < 100%, arbitrage exists.

Step 2: Calculate Stakes

Stake on Outcome 1: Total × (1/Odds1) / SumStake on Outcome 2: Total × (1/Odds2) / Sum

Where Sum = 1/Odds1 + 1/Odds2

Example Calculation

• Total budget: $1,000
• Team A odds: 2.10
• Team B odds: 2.10
• Sum: 1/2.10 + 1/2.10 = 0.952

Stakes:

• Team A: $1000 × (0.476/0.952) =$500
• Team B: $1000 × (0.476/0.952) =$500

Profit: $1050 -$1000 = $50 (5%)
