Prediction markets face Comer’s call for government trading ban

House Oversight Committee Chair James Comer has called for new restrictions on government officials trading prediction markets, including a possible outright ban, following an investigation that reviewed 1,700 pages of documents. The committee announced the findings in a Nov. 13 release. Traders in prediction markets such as Polymarket and Kalshi should watch for legislative follow-through, since a ban on official participation could reshape market credibility and participation rules.
