Arbitrage betting promises risk free returns – the Holy Grail of gambling – so is naturally a very popular topic within the betting community, but how does arbitrage betting work? We have laid out everything you need to know; this is arbitrage betting explained.
Τhe definition of Arbitrage betting:
Arbitrage betting exploits the opportunity to place proportionate bets on each outcome of the same event with differing bookmakers so that a profit is guaranteed regardeless of the outcome.
What is Arbitrage betting?
Any type of risk-based activity is a search for price-differential. If you can buy widgets from Factory A for €10 and sell them to Retailer B for €15 you can pocket €5 risk free.
A huge proportion of profit generated by the investment banking industry is based on this simple principle – in much more complex form – across a dizzying array of commodities and assets.
Arbitrage betting by comparison is much closer to the simple widget analogy above – it is used by many gamblers to successfully make risk-free profit.

Example of an arbitrage bet
The best way to explain how arbitrage works is through a simple example. Take the odds on a tennis match between Player 1 (P1) and Player 2 (P2) offered by two hypothetical bookmakers – A & B – as illustrated in the table below.
| P1 | P2 | Margin | Stake | Profit | |
| Odds BA | 1.30 | 3.93 | 102.4% | 26.54 | 4.30 |
| Odds BB | 1.42 | 2.90 | 104.9% | 73.46 | 4.31 |
| Arbitrage (P1/BB & P2/BA) | 1.42 | 3.93 | 95.9% | 100 |
The margin is indicated for each bookmaker i.e. the edge in their favour. By cross-matching the odds from Player 2 at Bookmaker A (3.930) with those for Player 1 at Bookmaker B, (1.420) the margin is in the bettor’s favour, providing a guaranteed return of 4.1% (100 – 95.9 = 4.1). Importantly, your stake needs to be in proportion to the odds as illustrated, which gives a guaranteed return of €4.30 whether Player 1 or Player 2 wins.
This principle can apply to any betting market, beyond just two selections, including spread betting, while it also has wide application in live betting where arbitrage opportunities are constantly available by Backing and Laying in a constantly shifting market. You can also use free bonuses in an arbitrage bet to lock in a guaranteed profit, but the conditions that apply are restrictive.
Why do arbitrage opportunities occur?
Though you may be simply interested in profiting from arbitrage, it is important for context to understand why arbitrage opportunities occur. These are the main reasons::
• Bookmakers differing in opinion
• Bookmakers taking a specific position or running a promotion
• Bookmakers slow to move their odds or simply making a mistake
The first of these is the most common, and is particularly relevant in relation to Pinnacle as their risk-management is regarded as among the best online. As a result, our odds feature more than any bookmaker in arbitrage opportunities, even more so because we don’t offer betting promotions.
Potential pitfalls of arbitrage betting
If at this point you are itching to get out there making free money from arbitrage betting, now is time for a reality check, as there is no such thing as a free lunch. Though the mathematical logic of arbitrage is sound there are risks associated with the process of finding and successfully placing the required bets. Here are the most important things to consider before starting out:
Stake limitation & account closure
Limits vary at different bookmakers, which may hinder your ability to properly exploit an arbitrage opportunity. This isn’t an issue at Pinnacle, as they offer the highest limits online.
Some bookmakers dislike arbitrage players as they don’t fit their desired player profile. As Pinnacle has a unique business model based on volume, they don’t care what the betting intent is – they are arbitrage friendly.
Bet cancelation
Bookmakers can cancel bets where mistakes have been made, which would leave you exposed on the other side(s). This can easily wipe out your profits accrued over a long period. Take a close look at the Rules for each bookmaker you intend to use for arbitrage.
Complexity
To fully exploit arbitrage betting, you must have a huge number of funded bookmaker accounts, as well as the time to take full advantage. This involves significant organisation and effort. Many practice arbitrage betting for a living (financial arbitrage) in which time invested must also be measured as a cost.
There are many services out there that will do the hard work for you of finding arbs, but they will charge a fee which eats into your profit, and do not eliminate all the risks outlined here!
Fleeting Arb Opportunities
Bookmakers are constantly updating their odds, often using their competitors as a benchmark. As a result arbitrage opportunities can last seconds rather than minutes so time of the essence, and when humans are time-pressured errors inevitably occur.
Arbitrage software systems can help in this regard, but cannot guarantee that you won’t be left with a naked position – in other words, you cannot cover all the bet options so will incur risk.
Arbitrage Betting – Getting Started
If you have got this far you should have enough information to consider arbitrage betting. If you want to take the next step then you’ll need a Pinnacle account (Register here a new Pinnacle account), because having the most competitive odds online along with an arbitrage friendly policy means that Pinnacle features in arbitrage betting opportunities more than any other bookmaker.
