How to Calculate NBA Arbitrage Bets
| Updated: 
Sports betting is a favorite pastime for people worldwide, and basketball is one of the most popular sports to bet on, regardless of a punter’s nationality or location. Unlike American football, basketball attracts considerable interest beyond the US, and avid fans can back their teams by placing bets at most online sportsbooks. This popularity is due not only to the sport’s global reach but also to its entertainment value and the opportunities it provides for diverse betting strategies. The wide variety of available bets makes basketball wagering even more interesting.
Although sports betting is often described as a hobby, leisure activity, or form of entertainment, most bettors ultimately hope to make a profit. For some professional bettors, it can be a primary source of income. Knowing the rules and staying up to date with information about teams and players is important, but it is not enough to ensure a successful basketball betting experience. Gambling enthusiasts use various strategies, one of the most popular being arbitrage betting. If you are unfamiliar with this term, keep reading to learn what it means and how it can contribute to lower-risk betting on basketball games.

Basketball Arbitrage Betting Explained
The word arbitrage is not strictly a sports term. It is also used in other fields, primarily economics and finance. Essentially, it refers to the practice of purchasing an asset or product and quickly selling it in another market at a higher price. It is often, though not always accurately, described as a risk-free operation. It is not difficult to see how this principle applies to sports betting. Sports arbitrage has existed since the early days of bookmaking but has become increasingly popular in recent decades alongside advances in online technology.
Arbitrage bets involve wagering on all possible outcomes of a given sporting event, with the aim of securing a profit regardless of the result. Basketball bettors who are well versed in this strategy can take advantage of differences between the odds offered by various online sportsbooks. If the bets are calculated and placed correctly, punters can earn a profit regardless of how the game ends.
If arbitrage betting has captured your interest, the first skill you need to master is monitoring several betting platforms so that you can place wagers on every possible outcome of the same event. Keep in mind that arbitrage opportunities may be available for only a limited time because odds are highly volatile. If you notice a significant disparity between the odds offered by different bookmakers, you must act quickly to take advantage of the opportunity before the prices change.
What Is the Reason for Different Betting Odds on the Same Event?
Arbitrage situations are not always the result of bookmakers reaching different conclusions about an event. Several other factors can cause discrepancies.
Competition for more punters
Online sports betting is a highly competitive field, with hundreds of sportsbooks operating on the internet. All of them want to maintain a steady customer base while attracting new punters. As a result, some bookies temporarily offer higher odds, potentially creating arbitrage opportunities.
Unusual short-term betting activity
Sure bets can emerge in moneyline markets when a sportsbook experiences an unusually high volume of wagers on one outcome. In such unpredictable circumstances, the odds for that outcome decrease, while the odds for the opposite outcome increase. If the same betting activity is not observed at other bookmakers, their odds may differ significantly.
Delayed reactions to live events
Basketball is a particularly dynamic sport, and a game can change dramatically in just a few seconds. Two consecutive three-pointers, for example, can give the trailing team enough momentum to reverse the score and eventually win the game. Events on the court happen so quickly that bookies sometimes fail to adjust their odds in time.
How to Find Arbitrage Betting Opportunities
Arbing has never been easy. Nowadays, it requires constant monitoring of multiple events across hundreds of online betting platforms, which can be burdensome and tedious. Modern punters typically use three methods to find arbitrage bets, two of which can save considerable time and effort.
The first is the old-fashioned manual search, which is still practiced by many bettors worldwide. If you choose this method, consider applying it to live betting events, where bookmakers may be more likely to make mistakes and create profitable arbitrage opportunities. On the other hand, live betting odds move extremely quickly, and you need experience to conduct a successful manual search during an ongoing event. Suitable basketball markets for this strategy include over/under points, handicaps, and quarter or half winners. If you are a novice, it may be wiser to place your bets during breaks in play.
A more convenient way to find arbitrage bets is to use free arbitrage scanner software. Providers of these services scan various online bookmakers and compare their odds to identify arbitrage opportunities. The advantages are clear: you can gain experience without paying for the service and identify opportunities faster than you could through a manual search. The software’s comparisons also show what each sportsbook offers and can help you determine which platforms best suit your preferences.
Punters should keep in mind two main drawbacks of using free arbitrage scanners. Because these services are free, many people use the same software. This can make the betting activity easier for bookmakers to detect and increase the likelihood that bettors will be flagged as arbers. Bookmakers generally do not welcome this type of betting activity. Another drawback is that most free scanners display arbs with a delay of approximately one minute. Although this may not seem significant, it gives users of paid scanners an advantage. If enough of them place their bets first, the odds may change before you have an opportunity to act.
Punters who want access to more arbitrage opportunities and the potential to increase their winnings may consider using paid versions of these services. Paid arbitrage finders generally display results without delay and do not limit results by profit percentage. It is better to use these scanners after gaining some experience because many of them are expensive, and you need to know how to make the most of their features. Some providers offer weekly subscriptions, allowing you to test whether the service suits your needs.
How to Calculate NBA Arbitrage Bets?
Now that you know how to find an arbitrage opportunity, it is time to calculate the wagers. After locating a suitable event, you should split your stake proportionally to secure the same payout for each possible outcome.
Consider an example involving a game between the Orlando Magic and the Philadelphia 76ers, with a total stake of $80. We are betting on which team will win, and the formula is as follows:
(1/Orlando Magic odds) + (1/Philadelphia 76ers odds) < 1
The odds included in our calculation are 1 (Orlando Magic) – 6.00 (Bookmaker “A”) and 2 (Philadelphia 76ers) – 1.50 (Bookmaker “B”).
(1/6.00) + (1/1.50) = 0.167 + 0.667 = 0.834, which is less than 1 and therefore indicates an arbitrage opportunity.
The $80 stake can be split as follows to secure a profit:
- 1 (Orlando Magic) – 6.00 (Bookmaker “A”) x $16.00 = $96.00
- 2 (Philadelphia 76ers) – 1.50 (Bookmaker “B”) x $64.00 = $96.00
This type of wagering locks both possible outcomes into a payout of $96.00 from the $80 stake. In other words, it produces a net profit of $16.00, or 20%, if both wagers are accepted at the stated odds.
5 Risks of Arbitrage Betting
Although an arbitrage betting strategy can minimize risk, nothing is entirely risk-free. Several unfavorable situations can arise, but many of them can be mitigated with careful preparation. Before placing real-money bets, it is important to understand both the potential profit from sports arbitrage and the associated risks.
Before you begin betting with real money, review our list of the 5 main risks associated with arbitrage betting and the steps you can take to mitigate them.
Odds moving too fast
As already explained, the basic principle of NBA arbitrage betting is to place at least two wagers at two online sportsbooks. Regardless of how fast your computer is, there will always be a delay of a few seconds between placing the first wager and the second. During this time, the bookmaker may change the relevant odds, leaving you in a position where the arb is no longer profitable.
Even if a bookie lowers the odds, the result may be a small loss or a reduced profit rather than the expected return. To minimize this risk, make sure you remain alert and use multiple monitors if possible. It can also be helpful to open separate accounts with different betting platforms. Do not confirm a wager until you are ready to place the corresponding wager with the other bookmaker involved in the arbitrage bet.
Human error
Mistakes are normal. Whether caused by a typo, transposition error, or failure to check the betting rules thoroughly, small errors can have serious consequences. In some cases, you may not realize that an error has occurred until the wagers are settled.
Experience can help reduce the likelihood of mistakes, so it is a good idea to begin with paper trading. Double-check or triple-check every detail before confirming your bets, and be prepared to address errors as soon as you notice them.
Different bookmaker settlement rules
Placing an arbitrage bet at online sportsbooks with different settlement rules can be risky. For example, the terms and conditions that determine how a bet is settled may vary if a coach withdraws a team because of a disagreement with the referees. One bookie may void the bet, while another may settle it as a win or loss. The solution is simple: read each sportsbook’s rules before placing a bet.
Palpable errors
Although they are not particularly common, online bookmakers may void bets if they believe that they made an obvious error when setting the odds, such as reversing the prices for the two teams. This risk may be greater at sportsbooks with questionable reputations or unclear licensing information. Sticking to reputable betting platforms can reduce the likelihood of encountering such a situation.
Account closure
A common risk associated with arbitrage betting is having your account restricted or closed by a bookmaker. Online bookies may monitor accounts for unusually frequent and consistently profitable wagers. Bettors who are considered too sharp or consistently successful may face account limitations. One possible tactic is to place several small, unrelated bets between your arbs, making patterns in your betting activity less obvious.
Conclusion
Sports arbitrage, particularly in basketball betting, can provide an opportunity to generate additional income by taking advantage of discrepancies between the odds offered by different sportsbooks. You should not expect to become a millionaire overnight, but careful calculations and effective risk management can improve your chances of making a profit. An individual arb usually delivers only a small return, but the profits can accumulate when the process is repeated successfully.
Arbitrage betting can also be combined with other strategies. One relevant example is value betting, which we examine in detail in the next article on our website.
