Polymarket has referred nearly 100 cryptocurrency wallets to law enforcement agencies as part of a broader effort to combat suspected insider trading, market manipulation and other prohibited activity on its prediction markets.
The disclosure was published on the platform’s Market Integrity page, where Polymarket said it has referred more than 90 accounts to authorities and regularly cooperates with regulators and law enforcement in ongoing investigations. The company added that it has provided details on more than 315 wallets while keeping individual cases confidential during active investigations.
The announcement marks one of the clearest indications yet that prediction market operators are taking a more proactive role in policing trading activity as the sector attracts growing attention from regulators worldwide.
Unlike traditional betting platforms, Polymarket settles trades on public blockchains, allowing investigators to examine wallet activity, transaction histories and trading patterns. While wallet addresses are pseudonymous, blockchain analytics can often link them to identifiable individuals through exchange records, on-chain behavior and other digital evidence.
Strengthened Surveillance Follows High-Profile Insider Cases
Polymarket’s integrity disclosure follows several high-profile investigations involving prediction market trading based on allegedly non-public information.
In April, the U.S. Department of Justice and the Commodity Futures Trading Commission charged a U.S. Army service member with using classified information to trade event contracts. The agencies publicly acknowledged Polymarket’s cooperation during the investigation, while the CFTC described the case as the first insider-trading enforcement action involving event contracts.
Media investigations have also identified suspicious trading patterns ahead of major geopolitical events, including military operations involving Iran and Venezuela. In several cases, newly created wallets placed unusually concentrated wagers shortly before market-moving developments, generating outsized profits and prompting questions over whether traders possessed confidential information.
Polymarket said its integrity team monitors markets for suspicious behavior and can ban wallets, pursue legal action or refer matters to authorities when warranted. The company also encourages users to report potentially manipulative trading directly to its integrity team.
Prediction Markets Face Growing Regulatory Focus
The referrals come as prediction markets continue to expand into politically sensitive, geopolitical and financial events where access to material non-public information could provide a significant trading advantage.
Traditional insider-trading laws were developed primarily for securities markets, creating legal questions about how they apply to event contracts tied to elections, military operations or government policy. Regulators in the United States and other jurisdictions have increasingly signaled that existing fraud and market-manipulation laws can still apply when traders misuse confidential information.
For Polymarket, demonstrating active market surveillance has become increasingly important as the platform seeks to build credibility with regulators and institutional participants. Public blockchain settlement provides investigators with a transparent audit trail unavailable in many conventional betting markets, allowing suspicious trading patterns to be reconstructed long after transactions occur.
While the company did not disclose how many referrals resulted in prosecutions or convictions, it confirmed that two arrests have already stemmed from matters referred by Polymarket.
As prediction markets continue gaining mainstream adoption, the platform’s latest disclosure suggests that blockchain transparency is becoming not only a feature for traders, but also an increasingly valuable tool for regulators and law enforcement seeking to preserve market integrity.
