Arbitrage Betting: Is Risk-Free Sports Betting for Real?

June 22, 2023

If you’ve ever come across terms like “risk-free betting” or “sure betting,” they often refer to a highly effective strategy known as arbitrage betting. Arbitrage betting requires time, commitment, and practice to be executed successfully, but it can be incredibly rewarding in sports betting. When done correctly, it guarantees an increase in your bankroll.

This article will focus on two-way markets, such as moneyline bets, totals, or spread bets, with only two possible outcomes. We will explore how arbitrage betting is feasible, how to identify opportunities, and the most effective methods to calculate your stake size to maximize profits.

What Is Arbitrage Betting?

Arbitrage betting involves identifying discrepancies or inefficiencies in the betting market to ensure guaranteed profits. Since bookmakers assign odds and probabilities to events with some degree of variation, there can be different odds between different sportsbooks. The key to successful arbitrage betting is taking advantage of these variations by putting bets on the same event at multiple sportsbooks. You can secure a profit regardless of the outcome by strategically wagering on all possible game outcomes.

Arbitrage betting requires time, commitment, and practice to execute effectively, but it is considered one of the most rewarding strategies in sports betting. When implemented correctly, it offers the assurance of increasing your bankroll.

Arbitrage betting can be seen as a form of hedging. While hedging involves taking offsetting positions to reduce risk or ensure a profit, an arbitrage bet entails simultaneously betting on all potential outcomes.

Arbitrage betting protects you from financial risks and positions you to generate profits under any circumstances.

How Arbitrage Betting Is Possible

Arbitrage opportunities in betting occur when various sportsbooks offer different odds for the same event. Line shopping, which involves comparing odds with other bookmakers, is essential for identifying and capitalizing on these opportunities.

Three main situations give rise to arbitrage betting opportunities:

  1. Errors in odds: Sometimes, bookmakers make mistakes and assign incorrect odds to an outcome, creating a discrepancy between sportsbooks.
  2. Differing opinions: Bookmakers may have varying assessments of the probability of an event, leading to differences in the odds they offer.
  3. Line adjustments: Sportsbooks may adjust their lines to balance the amount of betting action on both outcomes, attracting equal bets from bettors.

It is important to note that if a sportsbook makes a significant error, such as mistakenly offering odds of +250 instead of -250 for an outcome, they can void bets on that line. Although this occurrence is infrequent, it does happen sporadically. When bookmakers retract their posted odds, arbitrage opportunities are no longer viable.

Recognizing Arbitrage Opportunities

Recognizing arbitrage opportunities becomes easier when using American odds. Here are two simple ways to identify them:

  1. Positive odds higher than negative odds: If the positive American odds (indicated with a “+”) are greater than the negative American odds (marked with a “-“), it indicates the presence of an arbitrage opportunity. For instance, one sportsbook may offer odds of +102 for a particular outcome, while another provides odds of -101 for the opposite result. An arbitrage opportunity still exists even if the odds are +102 and +101 for the two outcomes.
  2. Implied probability less than 100%: Another approach is to convert American odds into implied probabilities. By calculating the implied probability for each outcome and adding them together, if the total is less than 100%, an arbitrage opportunity exists. For example, if both outcomes have odds of +110, they translate to an implied probability of 47.6% each. When combined, the total implied probability would be 95.2%. Since 95.2% is less than 100%, it confirms the presence of an arbitrage opportunity.

To better understand these concepts, let’s consider a practical example.

Arbitrage Betting in Action

You can place a $100 bet on both teams in this scenario. If the Pittsburgh team wins at Sportsbook A, you will receive a payout of $110 but lose the $100 bet on the Capitals. Conversely, if the Capitals win at Sportsbook B, you will receive a payout of $110 but lose the $100 bet on the Penguins. In either outcome, you will be left with a guaranteed profit of $10.

It’s important to note that this example represents a rare situation where a guaranteed 10% profit can be obtained through arbitrage betting. Typically, profit margins range between 1% to 5%, requiring bettors to wager a significant portion of their bankroll to secure a substantial profit.

For experienced bettors with a larger bankroll, the potential profits can be much higher by placing larger wagers. For instance, if a Bettor places $5,000 on both sides of the event in our example, they can lock in a guaranteed profit of $500. This demonstrates the significant potential rewards available in arbitrage betting for those with substantial resources.

Recognizing arbitrage opportunities and determining the appropriate stake sizes can be challenging due to the involvement of complex mathematical equations. However, helpful tools, such as odds aggregators and arbitrage calculators, can simplify the process for you.

Arbitrage calculators, on the other hand, assist in determining the optimal stake sizes for each bet to maximize your potential profit. These calculators consider the odds and the amount you plan to wager on each outcome, giving you the precise stake sizes required to achieve a guaranteed profit.
