U.S. lawmakers are intensifying scrutiny of prediction markets like Polymarket and Kalshi, citing concerns over potential insider trading, war profiteering, and the exploitation of sensitive government information.

Key Points

• Lawmakers are investigating reports of well-timed, profitable bets on sensitive geopolitical events, including U.S. military operations and foreign political transitions.
• Rep. Seth Moulton and other officials have criticized platforms for allowing wagers on the lives of service members, labeling the practice as unethical war profiteering.
• Senators Todd Young and Elissa Slotkin introduced bipartisan legislation to prohibit federal employees from using nonpublic information to trade on prediction markets.
• The Commodity Futures Trading Commission (CFTC) faces pressure to increase oversight, despite current staffing shortages and limited authority over offshore platforms.
• Kalshi has publicly supported federal regulation and onshore operations, while Polymarket continues to face criticism for its largely offshore, less regulated business model.
• California Governor Gavin Newsom issued an executive order banning state appointees from using nonpublic information to trade on these platforms.

Why it Matters

The rapid growth of prediction markets has created a regulatory vacuum that threatens public trust and national security by potentially incentivizing the misuse of classified information. Establishing clear federal guardrails is essential to prevent these platforms from becoming vehicles for insider trading and market manipulation by government insiders.
