Polymarket allows users to trade blockchain-based contracts on real-world event outcomes.
These contracts are priced between $0 and $1, reflecting implied probabilities.
Winners receive $1 per contract when the market settles, enabling profit from mispriced outcomes.
The Anti-Corruption Data Collective found insider trading indicators in political and military markets.
This high-risk trading volume represents 36% of Polymarket's total activity.
Reasons
Is the Polymarket trading system really the cause of insider trading, or just a place where it happens?
It seems the platform's ability to trade outcomes between 0 and 1 is simply a venue for action.
If someone has non-public information on a political event, they could use any system; the system itself doesn't create the information.
For example, if a government official knows about an upcoming policy change, that knowledge is the driver, not the mechanism for placing a bet.
Systemic insider risk occurs when low-probability bets consistently succeed across related markets.
This pattern suggests underlying information advantages not reflected in market prices.
It points to a systemic issue rather than isolated incidents of luck or mispricing.
Such risks are particularly evident in markets susceptible to insider knowledge.
Recent legal actions against athletes highlight the practical dangers of these markets.
Examples
It's easy to point to specific player betting manipulations and say the whole system is broken. But calling it "systemic insider risk" overstates the case without showing how one bad apple actually poisons the entire barrel.
If the problem only shows up here and there, like a few players getting caught, it’s not really a systemic issue; it's just individual misconduct. You must show the clear mechanism that connects these specific incidents across various markets for it to be truly systemic.
