How Do Bookmakers Set Odds for Niche Sports Like Curling or Competitive Eating?
Setting odds for popular sports like football, basketball, or horse racing is routine for bookmakers, who have access to mountains of data, years of historical results, and expert insights.
But what happens when the sport in question is curling or competitive eating, or some other lesser-known event?
How do bookmakers approach these niche markets, where information is scarce, and are the betting odds set differently?
The Basics of Setting Odds
For any sport, odds are set by assessing two main factors: the likelihood of an outcome and the bookmaker's margin.
In popular sports, bookmakers lean on comprehensive databases, algorithms, and expert opinions to calculate probabilities for different outcomes.
These include player stats, head-to-head results, weather conditions, injuries, and even recent form.
The sheer amount of data available helps to build accurate odds that attract bets while ensuring the bookmaker maintains an edge.
For niche sports, however, the equation becomes a lot trickier. With fewer data points, less media coverage, and smaller pools of expert opinion, bookmakers must rely on other sources and methods to create odds that still reflect the likely outcomes, but with more room for uncertainty.
Gathering Data on Niche Sports
When it comes to sports and events, the data that bookmakers can access is much thinner. These events often don't have the long-established histories or the volume of detailed statistics that larger sports enjoy.
So how do bookmakers get enough information to set odds?
Local and Specialist Knowledge

For niche sports, local experts or enthusiasts often provide insights. In curling, for example, knowledge about teams' playing styles, local tournaments, or rink conditions can be essential.
Similarly, in competitive eating, factors like a contestant’s eating history, the type of food, and past performances in similar events can make a difference.
Bookmakers may employ specialists or use forums and niche websites dedicated to these events for better insights.
Social Media and Public Sentiment
Niche sports fans and participants often gather in small, dedicated online communities.
For sports like competitive eating, YouTube videos of past events, interviews, and social media buzz might be key data points for oddsmakers.
This contrasts with mainstream sports, where data-driven algorithms dominate, and bookmakers rarely need to rely on public sentiment.
Adapting Popular Sport Models
Bookmakers might adapt models used in more popular sports, making rough estimates based on limited data.
For example, in curling, bookmakers may consider basic stats like win-loss records, but also factor in similar conditions to more familiar team-based sports when setting odds.
Risk and Margins for Niche Markets
The most significant difference when setting odds for niche sports is the level of risk.
Since bookmakers have less data, they have a higher margin for error, which affects how they set the odds.
With limited knowledge, the odds are often broader to cover the unknowns. This means higher potential payouts for bettors but also greater risks for bookmakers.
To balance out the lack of information, bookmakers may increase their margins on niche sports.
This means the odds on offer may not be as “fair” from the bettor's perspective compared to the odds for a more mainstream sport.
The bookmaker needs to cover their risk in areas where there is little reliable data, so they might offer odds that are less favourable.
After all, they are in the business of making money, not losing it!
Is It Easier to Win on Niche Sports?
One common belief among bettors is that it's easier to beat the bookmaker on niche sports due to the lack of information. There’s some truth to this idea.
In mainstream sports, bookmakers have a wealth of data and sophisticated models to calculate odds accurately, making it harder for bettors to find value.
But in niche sports, with less data to rely on, there is more room for interpretation and subjectivity, which can create opportunities.
Those who are passionate about niche sports may have an edge over bookmakers by having access to better, insider knowledge.
For example, a fan who regularly follows the curling circuit or a competitive eating enthusiast who keeps track of individual performance trends might spot patterns or know factors that bookmakers overlook.
This specialised knowledge can help the bettor identify value in the odds, leading to a better chance of winning compared to popular sports.
On the flip side, because bookmakers may offer wider odds to cover their uncertainty, there's also a greater risk for the bettor.
A single unexpected factor, such as a change in weather for a curling event or a competitor underperforming in a competitive eating contest, can quickly disrupt expectations.
With fewer data points to rely on, the unpredictability is higher, and so are the risks.
The Future of Niche Sports Betting
As technology and access to information improve, the gap between popular and niche sports betting might narrow.
The increasing availability of data for more obscure sports could allow bookmakers to set more accurate odds.
Streaming platforms and social media make it easier for bettors and bookmakers alike to access videos, analysis, and expert opinions on niche sports.
Bookmakers might also use artificial intelligence and machine learning algorithms to analyse whatever limited data is available and spot trends that human oddsmakers might miss.
This could potentially make betting on niche sports more sophisticated, and reduce the chances of fans having an edge through specialised knowledge.
Conclusion
Setting odds for niche sports like curling or competitive eating is a balancing act for bookmakers.
With far less data to rely on than for popular sports, they must dig deeper into specialist knowledge, fan communities, and even public sentiment.
The risk is higher, and margins often reflect that uncertainty. For bettors, this creates both opportunities and risks.
While it may be easier to spot value in niche markets due to the bookmaker’s lack of detailed information, the unpredictable nature of these sports can also lead to unexpected outcomes.
As data collection improves and niche sports grow in popularity, the way odds are set may become more refined, but for now, niche sports remain a wild card for both bookmakers and bettors.
By keeping an eye on specialist forums, competitor trends, and even social media, bettors can increase their chances of beating the odds in these less-trodden markets.
However, like any form of betting, it’s crucial to understand the risks involved.
