Full Report
Insider trading is rife on Polymarket: Analysis by the Anti-Corruption Data Collective, a non-profit research and advocacy group, found that long-shot bets—defined as wagers of $2,500 or more at odds of 35 percent or less—on the platform had an average win rate of around 52 percent in markets on military and defense actions. That compares with a win rate of 25 percent across all politics-focused markets and just 14 percent for all markets on the platform as a whole. It is absolutely insane that this is legal. We already know how insider betting warps sports. Insider betting warping politics—and military actions—is orders of magnitude worse...

# Main Topic
Analysis of systemic insider trading and information exploitation on the Polymarket prediction platform, specifically targeting sensitive military and defense sectors.
## Key Points
- **Anomalous Win Rates:** Large wagers ($2,500+) on low-probability outcomes (odds ≤ 35%) result in a 52% win rate for military markets, nearly four times the platform average of 14%.
- **Sector Specificity:** The variance is most pronounced in "military and defense actions," suggesting the threat is concentrated among actors with access to classified geopolitical intelligence.
- **Economic Incentive for Leaks:** The legality and liquidity of these markets create a financial pipeline for officials or contractors to monetize non-public state secrets.
- **Market Distortion:** High win rates for long-shots suggest the "wisdom of the crowd" is being superseded by "knowledge of the few," potentially leading to market manipulation.
## Threat Actors
- **Insider Threat (Geopolitical):** Individuals with access to classified military plans, diplomatic negotiations, or defense procurement.
- **Motivations:** Financial gain via low-risk, high-reward betting on outcomes they can influence or observe before public disclosure.
## TTPs
- **Exploitation of Information Asymmetry:** Leveraging non-public information to place bets on "long-shot" outcomes that are actually high-certainty events to the actor.
- **Selective Market Targeting:** Focusing on niche military/defense markets where information is tightly controlled and public data is scarce.
- **Threshold-Based Betting:** Strategically placing wagers of $2,500 or more to maximize profit without necessarily triggering standard platform fraud alerts.
## Affected Systems
- **Platform:** Polymarket (Prediction Market).
- **Sectors:** Military, Defense, and International Politics.
- **Data Integrity:** The reliability of prediction market data as an indicator of geopolitical stability is compromised.
## Mitigations
- **Regulatory Oversight:** Implementation of insider trading laws specifically for prediction markets involving government/military actions.
- **KYC/AML Enhancements:** Stricter "Know Your Customer" protocols to identify high-volume bettors with potential conflicts of interest.
- **Anomalous Activity Monitoring:** Platforms should implement triggers for users who consistently achieve high win rates on low-probability outcomes.
- **Information Security Policies:** Stricter controls and monitoring of personnel with access to sensitive data regarding events featured on prediction platforms.
## Conclusion
The data suggests that Polymarket is currently being utilized as a vehicle for monetizing insider information regarding military and defense actions. The 52% win rate on long-shot bets is statistically impossible without the presence of non-public information. This represents a significant risk to national security and information integrity, necessitating both regulatory intervention and platform-level defensive measures to prevent the commodification of classified intelligence.
