What is Arbitrage in Sports Betting?

Arbitrage betting, also known as sure betting, is a sports betting strategy that guarantees a profit, regardless of the outcome of an event.

Essentially, it involves exploiting differences in odds between multiple bookmakers by betting on all possible outcomes of a sporting event in such a way that no matter what happens, you end up with a profit 100% of the time.

For Nigerian sports bettors, the idea of making risk-free profits from betting will be undeniably appealing.

However, arbitrage sports betting isn’t a strategy that many punters in Nigeria are familiar with. It requires precise calculations, swift action, and a solid understanding of how bookmakers set their odds – skills that aren’t commonly associated with typical betting strategies here.

Nonetheless, for those who master it, the rewards can be well worth the effort. After all, the goal of every bettor is to make profits, and arbitrage betting provides a reliable way to do just that.

Remember, while we’re all chasing that big win, sports betting platforms are primarily in the business of taking your money. So, it’s in your best interest to learn and apply any technique that guarantees consistent profits.

With that in mind, we’ve put together this guide to help you understand what arbitrage betting is, how it works, how to spot arbitrage opportunities, and how you can use this strategy to boost your betting success.

The Basics of Arbitrage Betting

Arbitrage betting capitalises on differences in odds offered by various bookmakers for the same sporting event.

These discrepancies arise due to bookmakers having different opinions, algorithms, and customer bases.

A punter engages in arbitrage betting when they exploit these discrepancies to bet on all possible outcomes of a particular sporting event with different bookmakers in such a way that no matter the result, their total payout is more than their total stake.

So, they’re guaranteed a profit regardless of which bet wins and which loses.

How Does Sports Betting Arbitrage Work?

To engage in arbitrage betting, you must first determine if there’s an arbitrage opportunity, and to do this, you need to calculate the implied probability of each outcome.

Implied probability basically means the likelihood in percentage terms of an outcome occurring as implied by the bookmaker’s odds.

For decimal odds, the formula for implied probability:

  • Implied Probability = 1 ÷ Decimal Odds x 100

We’ll illustrate how this works with examples further down. Once you’ve calculated the implied probability for all possible outcomes, you sum them up. If the total is less than 100%, then an arbitrage opportunity exists.

Typically, bookmakers set their odds in a way that the combined implied probability of all possible outcomes exceeds 100%. This ensures the bookmaker gets a guaranteed profit on every bet, often referred to as their “margin” or “overround”.

Because of this, arbitrage bettors often place their wagers with different bookmakers, capitalising on the slight variations in odds across platforms to create opportunities for guaranteed profits.

How to Calculate Arbitrage Opportunity

In a football match between Chelsea and Liverpool, let’s say the odds from three different bookmakers are as follows:

  • Bet9ja offers 2.10 odds for a Chelsea win.
  • Betking offers 3.50 odds for a draw.
  • Betano offers 4.00 odds for a Liverpool win.

The implied probabilities for each outcome would be:

  • Chelsea win: 1 ÷ 2.10 x 100 = 0.4762 (or 47.62%)
  • Draw: 1 ÷ 3.50 x 100 = 0.2857 (or 28.57%)
  • Liverpool win: 1 ÷ 4.00 x 100 = 0.25 (or 25%)

Now, sum these probabilities:

  • 47.62% + 28.57% + 25% = 101.19%

In this example, the total is over 100%, so no arbitrage opportunity exists.

However, let’s say another bookmaker, Wazobet, is offering 4.50 odds on a Liverpool win. Recalculating the implied probability for that:

  • Liverpool win: 1 ÷ 4.50 = 0.2222 (or 22.22%)

Now, the sum is: 47.62% + 28.57% + 22.22% = 98.41%

Since the total is less than 100%, there is an arbitrage opportunity here.

Arbitrage Sports Betting Examples

Once you’ve identified an arbitrage opportunity, the next step is to calculate how much to bet on each outcome to guarantee a profit.

A straightforward way to do this is to first determine how much payout you want for each outcome and then divide that amount by each of the odds to find out how much to place on each outcome.

Say you want to ensure a ₦10,000 payout for each outcome. Using our example from above, this is how to calculate your stake on each outcome (rounding up to the nearest whole number):

  • Chelsea to win: ₦10,000 ÷ 2.10 = ₦4,762
  • Draw: ₦10,000 ÷ 3.50 = ₦2,858
  • Liverpool to win: ₦10,000 ÷ 4.50 = ₦2,222.23

So, you would bet ₦4,762 on Chelsea to win, ₦2,858 on a draw, and ₦2,222.23 on Liverpool to win, bringing your total stake to ₦9,842.22.

Now, calculate your potential profit based on each outcome:

  • If Chelsea wins, your payout would be ₦4,762 × 2.10 = ₦10,000.
  • If the match ends in a draw, your payout would be ₦2,858 × 3.50 = ₦10,000.
  • If Liverpool wins, your payout would be ₦2,222.23 × 4.50 = ₦10,000.

No matter the result, your total payout is around ₦10,000, and since your total stake was ₦9,842.23, you’ve made a risk-free profit of ₦157.77.

While this may seem small, successful arbitrage bettors often repeat this process across many games and events to accumulate profits over time.

As we’ve stated previously, arbitrage betting involves a fair amount of hard work, intensive research and mathematical skills, but that is the price you pay for guaranteed profits.

When done correctly, arbitrage betting ensures a profit no matter the outcome of the event.

Tools to Help Identify Arbitrage Betting Opportunities

Many bettors use software tools or odds comparison websites to find arbitrage opportunities quickly.

These platforms automatically scan the best betting sites in Nigeria for odds differences. They can also assist in calculating the correct bet amounts for each outcome.

Why Arbitrage Opportunities Exist

You might wonder why bookmakers offer such varying odds in the first place, allowing these arbitrage opportunities to exist. Here are a few reasons:

  1. Market Disagreement: Different bookmakers have unique algorithms, risk assessments, and customer bases. Because of this, they may have slightly different opinions about the likelihood of a given outcome.
  2. Timing Differences: Odds change over time as betting activity fluctuates. If you are quick enough, you can exploit discrepancies before bookmakers adjust their odds to align with the market.
  3. Promotions and Offers: Nigerian sportsbooks often run promotions, betting offers or enhanced odds for certain matches. This can lead to artificially high odds for specific outcomes, creating an arbitrage opportunity.

Challenges and Risks of Arbitrage Betting

While arbitrage sports betting is attractive, it’s not without its challenges:

  • Account Limiting or Banning: Bookmakers, including those in Nigeria, don’t take kindly to arbitrage bettors. If you’re consistently making risk-free profits, some bookies might limit your account or even ban you altogether. It’s essential to be discreet and not place arbitrage bets too frequently on the same platform.
  • Capital Intensive: Since arbitrage betting usually yields small profits per bet, you need a significant amount of capital to see meaningful returns. This might not be ideal for small-scale bettors who don’t have much to invest upfront.
  • Quick Action Required: Arbitrage opportunities are fleeting. Odds can change rapidly, and if you don’t act fast enough, the opportunity may disappear before you place your bets. Successful arbitrage bettors need to be highly organised and quick to react.
  • Errors in Calculation: A small mistake in your bet calculations or not fully understanding how odds work can turn what should be a profitable bet into a loss. It’s crucial to be meticulous and double-check your figures before placing any bets.

Is Arbitrage Betting Legal in Nigeria?

Yes, arbitrage betting is legal in Nigeria. However, while there are no laws prohibiting this strategy, bookmakers are within their rights to limit or ban accounts that consistently engage in arbitrage betting.

As a result, it’s important to scan the terms and conditions of any bookmaker you use and spread your bets across different bookmakers to avoid drawing attention to your arbitrage betting activity.
