Predictive analytics in gambling can help identify patterns associated with risky play, but a model’s score is an estimate—not a diagnosis and not proof that an intervention will prevent harm. The clearest current examples use account and play data to flag possible risk for safer-gambling action, rather than predicting who will win a bet or sporting event.
What predictive analytics in gambling is designed to do
In safer-gambling settings, predictive analytics uses recorded player behavior to estimate whether a pattern may indicate elevated risk. An operator or regulator can use that estimate to decide whether further review or an intervention is appropriate. The score is an output based on selected data and a defined model; it does not establish why someone is gambling in a particular way or determine their personal circumstances.
Signals may include the amount and frequency of bets, when and how often a person plays, and changes in play around winning or losing streaks. A model may detect patterns in those signals, but its results depend on what it was trained to recognize and how the data was collected.
This use is distinct from trying to forecast the result of a wager. In the UK Gambling Commission’s account of the OECD definition, an AI system infers outputs such as predictions or recommendations from input it receives; those outputs can influence physical or virtual environments. That definition describes AI generally, not a claim that gambling-risk models can reliably forecast an individual’s future behavior. The Commission’s approach to artificial intelligence

What player data can a model use?
Data can represent the pace, scale, timing, and context of play. The Dutch regulator, the Kansspelautoriteit (Ksa), describes a University of Amsterdam (UvA) model that considers how much and how often a person bets, repeated play at night, winning or losing streaks, and the player’s response to those streaks. The Ksa says the model description covers all forms of online gambling. Ksa description of the UvA algorithm
Those signals are observable behavior, not a complete account of a person’s financial situation, health, or reasons for playing. A score should therefore be read in the context of its target and limitations, not as a complete assessment of an individual.
What the Dutch UvA model shows—and what it does not
The Ksa commissioned UvA researchers to develop a machine-learning algorithm to estimate risky behavior in online casinos from actual play. UvA reports that the model’s dataset comprised bets made by players at 13 Dutch online casinos from 30 July 2023 to 30 July 2025. The data was made available for independent research under a legal provision. UvA describes the model as open source, independent, and transparent, with intended use in helping regulators detect risk and assess operators’ duty of care. UvA account of the model and dataset

The dataset’s size and time window are important context, not a guarantee that the model represents every player or gambling market. Its results should not be treated as universally transferable beyond the population and setting for which it was developed. Nor does the model diagnose addiction, guarantee that harm will be prevented, or replace an operator’s duty-of-care measures. The Ksa and UvA describe it as an instrument to inform detection and assessment.
What different model targets mean
A model can only be judged against the outcome it was designed to estimate. “Risky behavior,” a formal self-exclusion, and demonstrated gambling harm are not interchangeable targets.
| Example | What it uses or targets | What the cited source establishes |
|---|---|---|
| Ksa-commissioned UvA model | Behavioral signals from online casino play, including bet amount and frequency, timing, and responses to win/loss streaks. | UvA reports bets from players at 13 Dutch online casinos across 30 July 2023–30 July 2025; the Ksa describes the purpose as estimating risky behavior. The cited descriptions do not establish that a score is a diagnosis or that interventions based on it reduce harm over time. Ksa; UvA |
| BetBuddy model discussed in a Playtech paper | Recent play patterns similar to “serious self-exclusion,” which the paper defines as a formal request not to play on that operator’s system for six months or more. | The paper treats self-exclusion as a measurable proxy that captures only a subset of people experiencing harm. It discusses an explainability method and examples from a UK online bingo and slots provider; it is publisher research, not independent proof of commercial effectiveness. Playtech paper |
The contrast illustrates why the target matters: a model that identifies behavior associated with a formal self-exclusion is not necessarily identifying every person experiencing harm. Likewise, a model’s risk classification is not itself evidence that the person will experience a particular outcome.

Can machine learning predict gambling harm?
It can identify patterns or classify people against a defined target, but that is not the same as proving that a particular model predicts harm accurately in practice—or that acting on its score reduces harm. Predictive performance and intervention effectiveness are separate questions.
A 2026 systematic review examined 68 studies of technology in safer gambling. Within that literature, 16 studies concerned predictive-risk modelling using recent behavioral tracking data from 2015–2022. Methods in this category included tree models, regression, support-vector machines, neural networks, and other classifiers. These are counts of studies included in the review, not estimates of how many gambling operators use predictive analytics. 2026 systematic review
The review cautions that better detection, risk stratification, and tailored interventions do not by themselves establish sustained harm reduction. Results can be limited by conceptual, methodological, and interpretive problems. For a model to support a claim of prevention, evaluation needs to examine what happens after an alert and whether outcomes improve over time—not only whether the model separates one group from another.

How to evaluate a gambling-risk system
Operators, regulators, researchers, and readers comparing systems should ask what each one observes, predicts, and triggers. No single score or accuracy figure answers all of these questions.
- Data population and coverage: Which players, products, and time periods are represented? Does the data cover only one operator or market, and how well does it reflect the people the system will be used with?
- Predicted outcome: Is the model estimating a risk marker, formal self-exclusion, an observed harm outcome, or another proxy? Is that target clearly defined?
- Validation and errors: How was the model tested beyond its training data? Are its estimates calibrated, and how are false positives and false negatives assessed, including across different groups?
- Explainability and challenge: Can an appropriately qualified reviewer understand the factors behind a score well enough to question or contextualize it?
- Intervention design: What happens when a score crosses a threshold? Who decides, when does contact occur, and is there evidence for the timing and content of the action?
- Governance and data handling: What legal basis permits the use of the data? Who can access it, how long is it retained, and what human oversight and assurance apply?
- Outcome evidence: Does the evidence describe model performance alone, or does it show improved outcomes sustained over time after interventions?
These questions matter because an alert is only one part of a safer-gambling process. The systematic review describes technologies that can monitor behavior, provide information or personalized feedback, show objective win/loss information, set deposit, loss, or time limits, offer cool-off periods, and enable exclusion. Their presence does not establish that any particular intervention is effective for every person or context. Systematic review of safer-gambling technologies
Intervention timing also deserves scrutiny: a score that arrives too late, or a message that does not fit the situation, may not serve the intended purpose. The Responsible Gambling Council’s project listing describes work with Playtech to map the player journey and identify points for timely information-sharing and safer-gambling communications. That supports treating the timing and delivery of an intervention as part of evaluation, rather than assessing a model on its score alone. Responsible Gambling Council project listing

Governance depends on the jurisdiction and use
Responsible deployment requires more than a technically functioning model. The UK Gambling Commission says its own use of AI should be lawful, appropriately transparent, responsible, consistent with licensing objectives, subject to human intervention, governance, and assurance, and carried out by people with the necessary skills. It identifies possible regulatory uses such as compliance assessments, breach detection, targeting illegal gambling, and understanding markets and consumer behavior. This is the Commission’s framework for its own approach, not a universal legal standard for operators elsewhere. UK Gambling Commission AI approach
A UK Parliamentary answer states that operators in Great Britain must hold a Gambling Commission licence and comply with codes of practice, including social-responsibility policies and procedures to reduce risk and seek to identify people struggling with problem gambling. It also says the Commission can remove a licence if an operator deploys AI in a way that undermines statutory objectives and duties. These statements concern Great Britain; legal requirements differ by jurisdiction and can change, so operators should check the rules that apply to their market and the date of deployment.
