What Is Arbitrage Betting? 

It’s a bet placed using a strategy that allows players to guarantee themselves a profit by placing numerous bets that cover all the possible outcomes of an event. 

Key to the strategy is exploiting discrepancies in odds laid by different esports betting sites on the same event, although it’s also possible to place arbitrage bets with the same sportsbook.

One of the key points about betting arbitrage is that it’s a purely mathematics-based strategy that requires no knowledge at all of the sport or event in question. 

Following that, the strategy can be applied to betting on any sport, from the winner of a tennis match to the winner of an esports match. 

How Does Arbitrage Betting Work?

When placing an arbitrage bet, you’re eliminating any element of risk by relying on maths/odds. 

Here’s how to place an arbitrage bet on esports. 

  1. Open an account at any esports betting site that is licensed and regulated. Then, make a real-money deposit.  
  2. Navigate to the esports betting section of the site. 
  3. Choose an esports match you’re thinking of betting on. 
  4. Navigate to a market that has two runners in it, as arbing a two-runner market is far easier to do than for markets with three or more runners. 
  5. Let’s say you have identified a Valorant match between Sentinels and Team Heretics as one providing a potential arbitrage opportunity. 
  6. When examining different sportsbooks, you’ve noticed that Sentinels are available at +130 with sportsbook A, while Team Heretics are available at +125 with bookie B, which appears to be a potential arbitrage opportunity. 
  7. Next, you need to apply the arbitrage betting formula to the odds on offer. 
  8. Start by converting the American odds into implied probability. 
  9. In the case of this esports match, applying the formula yields the following results, which are listed in the images below.
  10. You’ll then need to enter the implied probabilities and other details of the bet into an arbitrage betting calculator, which will provide you with the amount you’ll need to wager on both outcomes to generate a profit. 
  11. Watch the action unfold, and providing you’ve staked correctly, you’ll have your profit paid out once the event reaches a conclusion.

When looking at the example used in our step-by-step guide, you’ll be able to see how the arbitrage betting formula is broken down in an esports event.

If the number is below 1, this will always provide an arbing opportunity, and the lower the number, the better. With the figure of 0.8792, you have an arbing opportunity. 

Where Can You Find Arbitrage Betting Opportunities?

You’ll be pleased to hear that there are many different ways in which you can find arbitrage betting opportunities. There are thousands of sporting events every week to bet on, including dozens in the world of esports, and there are hundreds of sportsbooks laying ever-changing odds on these events.

Use odds comparison sites 

There are plenty of odds comparison sites out there that will display the latest odds that a particular sportsbook is offering on a particular site, in real time. 

For example, you can compare the odds of Ninjas in Pyjamas beating paiN Gaming in a match of Blast Bounty across different sportsbooks and spot arbitrage opportunities yourself. 

This is one of the more manual approaches, with the main challenge being that if the odds aren’t displayed in ‘actual’ real time, with delays in the updating of the odds, the latest odds may not be completely accurate. 

Join arbitrage communities 

The big battle in the world of sports betting is not between players and players, but rather between players and sportsbooks. 

It follows that players are happy to share their knowledge and insights among each other in a bid for all players to beat the sportsbooks as a community. 

Use arbitrage betting software 

These tools continuously scan the latest odds on a specific betting market for a particular event, 24/7, in real-time, making this the least manual and most automated method used to find arbitrage betting opportunities. 

The tools alert you to arbing opportunities, and you can easily set them up so they only flag up esports arbing opportunities, if that’s the sport you’re interested in when it comes to arbitrage bets

Arbitrage Betting Esports Examples

Here are some other arbitrage betting examples related to esports, which we hope will provide you with a more relatable approach to this type of betting. 

Bet on Team A to win pre-match, bet on Team B to win in live betting 

Let’s use the example of the Sentinels v Team Heretics again. This time, you’re still backing the Sentinels at +130 pre-match to beat Team Heretics, but in the absence of pre-match arbing opportunities, you need to wait. 

Knowing that the match will be offered in live betting, you follow the moneyline market while the match is in progress and wait/hope that Team Heretics reach +120 in live betting, using the same $49.5/$50.5 staking plan as before. 

Theoretically, you could do this just on one sportsbook, but the danger with that is that it will be far more obvious that you’re arbing, which sportsbooks don’t like you doing. A better alternative is to place the pre-match bet with sportsbook A and the live bet with sportsbook B. 

Back the pre-match underdog in Map Betting and arb 

Even though esports is something of a niche sport to bet on, sportsbooks are already wise to the abilities of the best-known teams. That’s particularly true of the moneyline market for an esports match, but it may not be the case when it comes to some of the other markets. 

If you know the esports teams well, you may be better informed about which teams are stronger on specific maps than the sportsbook is. That means you may get a wrong pre-match price on the outsider with a particular sportsbook, making it easier to arb, whether that’s still pre-match or in live betting
