Preventing manipulation or fraud is critical when you build a Prediction Marketplace. Users need to trust that outcomes are fair and predictions are accurate, so the platform must include strong safeguards.

By combining technology, clear rules, and continuous monitoring, a business can detect and prevent suspicious activity early, ensuring a secure and trustworthy experience for all platform users.

• Set limits on bets/predictions to reduce market manipulation
• Apply reputation and scoring systems to reward honest predictors
• Ensure transparent rules and settlement processes
• Use secure and tamper-proof data storage (e.g., audit logs or blockchain)
• Restrict or flag suspicious coordinated activity (collusion)
• Add manual review systems for high-risk or large transactions
• Keep real-time monitoring and alerts for abnormal spikes
