Underdog adopts Eventus surveillance for betting markets

Underdog announced it has integrated Eventus surveillance technology across its platform to monitor activity on its betting and contest markets. The rollout covers both pregame and in-play contests and was completed recently as user volume on the site increases.

Eventus supplies software that ingests transaction and event data, reconstructs sequences of bets, and applies rule-based and machine-learning analytics to identify anomalous patterns. The system generates real-time alerts for operations and compliance teams, produces records for internal review and regulator reporting, and supports faster investigation of flagged activity.

The implementation is designed to detect behavior such as coordinated collusion, automated bot activity, abnormal staking patterns and attempts to exploit timing or pricing errors. Underdog operates daily fantasy contests, pick’em pools and moneyline-style prediction markets, formats that create high transaction volumes and complex data flows on game days.

Eventus’s tools offer replay and audit capability so investigators can follow the sequence of events that led to an alert. The platform captures wager size and timing, correlates related accounts, and looks for repeated patterns across accounts and time. Customizable rules and reporting dashboards allow teams to adjust detection thresholds and prioritize specific risk indicators.

Operators in online sports gaming and prediction markets contend with automated scripts, multi-accounting and schemes that try to take advantage of information asymmetries or platform errors. The surveillance layer produces a documented investigatory trail that can support account suspensions, contest voids or regulatory inquiries when necessary.

No further details were provided about the specific detection rules or the full scope of the integration. Underdog confirmed the Eventus tools will complement its existing customer-safety and fraud-prevention systems and are intended to help maintain fair play across its contests.
