What is Market Surveillance?
Ensuring fair play and market integrity is vital for both bettors and bettng market providers. Market surveillance is the process that aims to detect and prevent illicit activities by observing the overall health of the market. An unhealthy market might be affected by information asymmetry where one or more parties might have access to some form of insider knowledge.

Market surveillance involves closely monitoring all aspects of betting market activity to identify anomalies and to detect and prevent market manipulation.
Surveillance is a core protective activity that does this by ensuring that prices in the market are being formed in a fair and open environment, and helps to reduce the potential or real level of information asymmetry.
The Significance of Information Asymmetry
Information asymmetry, which creates a knowledge imbalance, arises when one party has more private or non-public information than another party in a market.
The resulting informational disadvantage can result in an opportunity for unfair advantages to the knowledge-holder, and is a situation where one trader is said to have an informational advantage. This can also create a situation that results in adverse selection, where an uninformed trader makes decisions that are to their detriment.
By identifying and combating information asymmetry, markets are kept fair and open, and bettors can have more confidence in their overall chance of success.
Insider Trading: A Major Threat
Insider trading, where individuals use non-public or confidential information for personal gain is a key area of concern for market surveillance teams.
These are illegal practices that constitute market abuse. They are forms of illicit activity and also fraudulent activity that undermines the overall integrity of the market and are a breach of confidential data policies.
These activities must be identified, prevented, and prosecuted, to keep markets fair and honest.
By detecting insider trading activity there is potential for preventative measures to be taken, often up to the level of prosecution.
Proprietary Information and Its Misuse
Proprietary information refers to non-public information or confidential data that is not available to all market participants.
When used improperly, this private information, or material information provides an exclusive access that allows the possessor of this data to engage in informed trading.
By monitoring the market for misuse of this information, and keeping it from getting into the wrong hands, market surveillance helps prevent unfair advantages. This requires a strong focus on risk management.
Market Manipulation: Distorting Prices
Market manipulation involves actions to artificially distort the market by using price fixing techniques. These techniques will cause market distortion.
Examples of market or odds distortion can include influencing market prices or attempting to create unfair practices through the use of trading volume. Other methods may be used, too, which will often constitute fraudulent behaviour.
By identifying and preventing market manipulation, market surveillance can help maintain accurate and fair prices in the betting market. It ensures that price is being formed genuinely and openly.
Order Book Analysis and Trading Patterns
Order Book Analysis involves examining all outstanding buy and sell orders, to better understand market depth, and is a key part of market surveillance. These techniques may also include the study of trading patterns and the ways that activity occurs in the market.
Understanding market tendencies and trading habits will provide information on the general flow of the market via use of a range of data analysis techniques.
Understanding market activity and order placement patterns helps to identify any irregularities that require investigation.
Anomaly Detection: Spotting Suspicious Activity
Anomaly detection is the process of using algorithmic techniques to identify unusual activity and potentially suspicious behaviour.
These techniques can spot statistical outliers and pattern deviations that may indicate the presence of illicit or aberrant actions that are out of the normal course of market activity. This may require close monitoring, using a real time monitoring approach.
Anomaly detection allows market surveillance to identify irregularities that could point to potential insider trading or market manipulation.
Informed Trading and the Knowledge Gap
Informed trading occurs when a trader has access to superior information, giving them an advantage. This will be through access to privileged information that is not available to the public and may be a result of strategic information use. This approach may be deemed knowledge based trading or a well-informed approach.
By understanding the mechanisms of informed trading, we can better reduce the opportunities for its implementation.
Regulatory Compliance and Market Integrity
Finally, all market surveillance activities must be underpinned by a solid foundation of regulatory compliance, which ensures the overall integrity of the market.
This compliance will involve the implementation of rules and regulations and an overall adherence to a range of legal obligations.
All activities must also align with the core principles of ethical trading standards and the policies must be properly enforced with a range of risk mitigation policies in place.
By ensuring regulatory compliance, market surveillance helps to foster trust in the fairness of the market.
Summary
In summary, market surveillance is a vital function that seeks to promote fair play and reduce the possibility of illicit activity within sports betting markets.
By closely watching market activities, identifying irregularities, and using a range of techniques, operators can reduce information asymmetry and promote an overall more transparent and fair market.
