Reference database of integrity red flags and suspicious betting indicators documented by regulatory bodies and integrity organizations. Use these markers for monitoring and compliance training.

• Critical

  Unusual High-Volume Betting on Obscure Markets

  Disproportionately large wagers placed on minor events or exotic markets (e.g., exact score, corner counts) that typically see minimal liquidity. Often indicates coordinated manipulation where fixers target less-monitored markets.

• Critical

  Concentrated Betting from High-Risk Jurisdictions

  Sudden influx of bets originating from regions with documented match-fixing networks or weak gambling regulation. May indicate coordinated activity through accounts in multiple jurisdictions.

• High

  Late Money Surge Against Market Direction

  Large wagers placed in final minutes before event that contradict established market sentiment. Often accompanied by confident maximum-stake betting despite unfavorable odds.

• High

  Coordinated Multi-Account Betting

  Pattern of similar bet placement across multiple accounts with shared characteristics (IP addresses, payment methods, betting patterns) suggesting single controlling entity evading detection.

• Critical

  Unprecedented Odds Movement Without News

  Dramatic shifts in odds (>20% implied probability change) occurring without injury news, weather changes, or other legitimate factors. Steam moves from Asian markets often precede manipulation alerts.

• High

  Divergence Between Major and Minor Books

  Significant odds discrepancy where regulated books show stable prices while offshore or lower-tier operators display unusual movement, suggesting informed money targeting weaker monitoring.

• Medium

  In-Play Odds Suspension or Removal

  Operators removing or suspending in-play markets mid-match without clear cause (injury, weather). May indicate detection systems flagging unusual activity or erratic on-field behavior.

• Critical

  Unexplained Performance Anomalies

  Athletes or teams performing dramatically below established baseline with no injuries, playing conditions, or legitimate factors explaining the discrepancy. May include uncharacteristic errors at critical moments.

• High

  Last-Minute Lineup Changes Without Explanation

  Unexpected withdrawal or substitution of key players announced close to match start, potentially to align with pre-placed bets on weakened team performance.

• High

  Irregular Point/Score Patterns

  Scoring patterns that appear inconsistent with competitive play, such as intentional errors at specific times, games thrown at predictable margins, or players losing consecutive games to break.

• Medium

  Contact with Known Corruptors

  Evidence of players, officials, or team staff associating with individuals previously banned or prosecuted for match-fixing, including social media connections or physical meetings.

• High

  Low Player Compensation Relative to Betting Volume

  Events generating significant betting turnover while participants receive minimal remuneration, creating corruption vulnerability. Common in lower tennis tiers, minor football leagues, and semi-professional competitions.

• High

  Weak Regulatory Oversight

  Competitions in jurisdictions lacking sports betting regulation, integrity monitoring frameworks, or information-sharing agreements with operators and sports governing bodies.

• Medium

  No Integrity Unit or Code of Conduct

  Sports or leagues lacking dedicated integrity infrastructure including participant education, reporting mechanisms, betting monitoring partnerships, or enforceable sanctions.

• Medium

  End-of-Season Dead Rubbers

  Matches with no competitive significance where teams have already secured standings, reducing motivation and creating opportunities for manipulation without affecting league outcomes.
