James Comer News & Prediction Market Coverage

Comer, as House Oversight chair, opened a probe into potential insider trading on Polymarket and Kalshi, focusing on whether users including government employees trade on non-public legislative or regulatory information; he demanded surveillance records from the CEOs by June 5.

No; the investigation targets insider trading and surveillance practices rather than prohibiting the platforms, consistent with prior support for regulated markets.

Not yet; he issued document demands with a June 5 deadline and indicated subpoenas may follow if needed.

The committee can compel documents and testimony, hold hearings, refer matters to the DOJ, and issue public findings that influence other regulators, though it cannot directly fine or license platforms.

Concerns center on suspicious trades tied to events like the Iran conflict and whether participants with privileged access exploit non-public information on political, policy, or geopolitical outcomes.

The investigation remains active following the May announcements and document demands, with potential for further action including subpoenas amid parallel regulatory proceedings.
