The US House Oversight Committee has launched a formal investigation into prediction market platforms Kalshi and Polymarket, demanding detailed documentation on their identity verification processes and trade surveillance capabilities by 5 June. Committee Chair James Comer is requesting internal records showing how each platform detects suspicious trading patterns and prevents insider activity, applying the compliance standards normally reserved for registered derivatives exchanges.
The inquiry follows two high-profile incidents that exposed gaps in market integrity controls. Federal prosecutors indicted a US soldier for allegedly generating roughly four hundred thousand dollars in profits on Polymarket using classified intelligence, while Kalshi suspended three congressional candidates caught betting on their own election outcomes. These cases have prompted lawmakers to scrutinise whether prediction markets can adequately police insider trading and maintain appropriate surveillance infrastructure.
Congress is specifically examining three areas: auditable transaction records that could support enforcement actions, KYC systems including verification methods for domestic and international accounts, and automated anomaly detection capabilities. The investigation highlights a regulatory divide between the two platforms. Kalshi operates as a CFTC-regulated exchange with established compliance frameworks prohibiting anonymous trading. Polymarket’s blockchain-based architecture and international accessibility present more complex challenges, as its decentralised structure was not built around traditional transparency requirements now being demanded by Washington.

Prediction markets are facing the same regulatory maturity test that transformed retail FX and CFD markets a decade ago—demonstrating robust KYC, transaction monitoring, and real-time surveillance is now the price of institutional legitimacy.
