Sports betting has come a long way in India, transforming from a clandestine activity into a billion-dollar industry with rapid growth over the past few decades. This evolution isn’t just about the rise of digital platforms, but also the changes in how betting odds are calculated. The evolution of sports betting odds calculations in India has been deeply influenced by various factors, including technological advancements, cultural changes, legal frameworks, and the growing appetite for sports like cricket, football, and kabaddi. This article will delve into the history and development of sports betting odds in India and how these calculations have evolved over time.
The Beginnings of Sports Betting in India
Sports betting in India can be traced back centuries, long before the internet and modern technology revolutionized the way we engage with betting markets. Initially, betting was a localized, informal practice, where wagers were placed on various traditional sports such as kabaddi, wrestling, and, most notably, cricket. Cricket, with its deeply ingrained presence in Indian culture, quickly became the focal point of the betting scene, attracting bettors from all walks of life.
In these early days, the process of calculating betting odds was rudimentary. Bookmakers, often with a deep understanding of the sport, would manually set the odds based on their knowledge and intuition. There was no complex mathematical modeling or data analysis to guide their decisions; rather, odds were shaped by the general atmosphere surrounding a game or match. The popularity of teams, the star power of individual players, and the prevailing public sentiment were all considered when setting odds.
The odds themselves were relatively simple in the early years, typically communicated in fractional terms such as “2:1” or “3:1,” which represented the payout ratio to a bettor’s stake. For instance, if you placed a bet of ₹100 at 2:1 odds, you stood to win ₹200 if your bet was successful. This basic format made it easy for bettors to understand, even though they didn’t fully grasp the intricacies behind the odds calculations. The bookmaker’s experience and the public’s general opinion formed the core of these early odds-setting methods.
In a time before data-driven technologies, the role of bookmakers was incredibly important, as they essentially acted as the gatekeepers to the betting world. There were no computers or digital platforms to compare odds or to track the nuances of each match. Instead, bets were placed through personal interactions or small community networks. This made the betting scene somewhat opaque, with many bettors relying heavily on trust and word of mouth rather than detailed statistical analysis. The betting world was small, and the odds were set through a combination of knowledge, intuition, and the mood of the public.
Early Odds Calculation Methods
In the early days of sports betting, the methods used to calculate odds were much simpler and less sophisticated compared to today’s data-driven models. Back then, bookmakers relied on their intuition, experience, and knowledge of the sport to manually set the odds. The concept of odds was introduced to provide bettors with an understanding of the potential profit they could make on their wagers. However, the process was rudimentary and often lacked the accuracy and complexity that we see in modern-day betting.
- 1:1 Odds
Also known as “evens” or “even money,” this ratio indicated that a bettor would double their stake if they won. For example, if you placed a bet of ₹100 at 1:1 odds, you would win ₹100 if your bet was successful, essentially receiving the same amount you wagered. - 2:1 Odds
With 2:1 odds, the bettor would win twice the amount of their stake if they won the bet. For instance, a ₹100 bet at 2:1 odds would return ₹200 in profit. These types of odds were often used for bets considered less likely to succeed, as the higher odds reflected the greater risk for the bettor. - 3:1 Odds
This represented an even greater potential payout. For every ₹100 wagered at 3:1 odds, the bettor would receive ₹300 in return if their bet was successful. As with 2:1 odds, the 3:1 odds were generally applied to situations where the outcome was less predictable or the likelihood of success was lower. - Fixed-Rate Odds
Many early odds were also set based on a fixed amount, often reflecting the general sentiment of the community or the bookmaker’s own judgment. This type of odds calculation was quite subjective and could vary greatly depending on the bookmaker’s perspective or even the location of the bet.

Introduction of Computer Models
The late 1990s and early 2000s marked a significant shift in the world of sports betting with the introduction of computer models for calculating odds. Before this technological advancement, odds were set manually by bookmakers based on their knowledge and intuition, which often led to inaccuracies and inefficiencies. The introduction of computers and specialized software changed the landscape of the industry by allowing bookmakers to use complex models that incorporated a vast array of data. These computer models analyzed multiple variables that had previously been difficult or impossible to account for manually.
One of the major advantages of computer models was their ability to process large amounts of data quickly and efficiently. Bookmakers could now consider various factors like player statistics, team performance, historical match data, and even weather conditions when setting odds. For example, a bookmaker could analyze a cricket player’s batting average over the last few seasons, their performance in specific weather conditions, and the historical outcomes of matches between two teams to create more accurate predictions. This holistic approach gave bookmakers a much deeper understanding of the dynamics that influence the outcome of a sporting event.
The use of computer models allowed for the development of more sophisticated odds calculation techniques. With the power of advanced algorithms, bookmakers could process data in ways that were previously unimaginable. These models could incorporate real-time information such as injuries, team lineup changes, and fluctuations in betting patterns, further refining the odds. As technology progressed, the scope of the models expanded to include machine learning techniques. These techniques allowed the models to learn and adapt over time, improving the accuracy of predictions based on newly acquired data.
The shift from manual calculations to computer-generated odds was revolutionary, not only in terms of accuracy but also in the dynamic nature of the betting market. Traditional odds were often static, meaning once they were set, they didn’t change until after the event. However, with computer models, odds could be adjusted dynamically in real-time, responding to new information and shifts in the market. This made sports betting more competitive and transparent, as bettors could now trust that the odds were being calculated based on a broad range of factors and updated regularly. The introduction of computer models was a game-changer for the sports betting industry, paving the way for even more technological innovations in the years that followed.
