It would be impossible to manage manual monitoring of betting behaviours, and clearly monitoring (and associated reactions, if necessary to protect the bookmakers interests) is important from several angles. So, by inference, there must be algorithms that do the work.

Yes, bookmakers run sophisticated algorithms to monitor punters' betting behavior. These algorithms analyze various factors to detect patterns, assess risk, and manage potential liabilities. Here are some key areas where bookmakers use algorithms:
1. Behavioral Monitoring
Algorithms track betting patterns, such as bet size, frequency, the sports or events being bet on, and the markets used (e.g., live bets, accumulators). This helps bookmakers identify punters who may have advanced knowledge or betting strategies that give them an edge over the house.
Machine learning models can learn from a bettor’s past behavior and predict future actions, flagging irregularities or suspicious activity.
2. Identifying Sharp Bettors
Bookmakers use algorithms to detect "sharp bettors" or professional gamblers who consistently place successful bets. These bettors are more likely to have advanced systems, use statistical models, or take advantage of arbitrage opportunities. Once identified, sharp bettors may face account restrictions, lower bet limits, or even have their accounts closed.
3. Risk Management
Risk management systems use algorithms to assess the potential risk of a bet to the bookmaker. These algorithms analyze market trends, public sentiment, and betting volume. If a sudden surge of bets on a particular outcome is detected, the algorithm may adjust the odds to protect the bookmaker's profit margins.
Liability management is a crucial component, ensuring that the bookmaker doesn't expose itself to massive losses on particular events or bets.
4. Anti-Fraud and Anti-Collusion
Bookmakers deploy fraud detection algorithms to monitor for signs of collusion between punters or match-fixing. For instance, sudden coordinated bets placed by multiple accounts on unlikely outcomes may raise flags.
Geolocation and IP tracking algorithms are also used to ensure that users are betting from allowed regions and to detect multiple accounts from the same location, which could indicate fraudulent activity.
5. Responsible Gambling
Some platforms use algorithms to monitor problem gambling behaviors. By analyzing patterns such as chasing losses, increasing bet sizes after losses, or frequent betting late at night, the algorithms can flag potential signs of gambling addiction. Once flagged, responsible gambling tools like self-exclusion options or deposit limits can be suggested or enforced.
6. Personalization
Algorithms are also used to personalize the betting experience for users. By analyzing past behavior, the system can recommend specific markets, events, or promotions that align with a punter's betting habits, enhancing the user experience.
Conclusion:
Bookmakers leverage algorithms and machine learning for a wide range of purposes, from identifying professional bettors and managing risk to ensuring fair play and responsible gambling. These systems provide insights into bettor behavior and allow bookmakers to protect their business interests while maintaining a fair betting environment.
