US House Committee Launches Oversight Probe into Kalshi and Polymarket Insider Trading Risks

U.S. House lawmakers have initiated a formal inquiry into the operational oversight and regulatory safeguards of prominent prediction markets Kalshi and Polymarket. Led by Representative James Comer, chairman of the House Committee on Oversight and Accountability, the investigation seeks to address growing concerns regarding potential insider trading and market manipulation. The probe is specifically focused on whether these platforms adequately mitigate risks associated with sensitive national security information and military intelligence. This regulatory action follows reports of suspiciously timed betting activity preceding significant geopolitical events and military maneuvers. By scrutinizing how these platforms handle high-stakes data, Washington is signaling a new, more aggressive stance toward the decentralized betting sector, which has increasingly challenged traditional polling methods. The outcome of this probe could determine the future regulatory framework for prediction markets in the United States, as lawmakers weigh the benefits of crowd-sourced forecasting against the potential for illicit market activity that could compromise national security and integrity in the digital financial landscape.
