House Democrats push subpoena of prediction market records over Iran oil trades
House Democrats are pressing the House Oversight Committee to subpoena internal records from prediction market platforms, with the probe focused on suspicious trades linked to Iran and oil futures that suggest possible insider trading. The request, initiated by a New Hampshire congressman and broader Democratic members, targets trader identities behind the questionable positions. Neither source named the specific lawmaker, the targeted prediction market operators, or the exact timing of any committee vote on the subpoena. The investigation reflects widening congressional scrutiny of prediction markets following concerns that non-public information about geopolitical events may be fueling profitable trades ahead of public disclosure.
Any platform compelled to comply—likely Kalshi or Polymarket given their dominance in geopolitical contracts—would face forced disclosure of trader identities and position history, chilling participation in sensitive event markets or triggering voluntary delisting of conflict-linked contracts to avoid repeat demands.
