CME's Duffy clashes with CFTC chair and Kalshi at first event-contract advisory meeting
CME Group CEO Terry Duffy clashed with CFTC Chairman Michael Selig and Kalshi at the first CFTC Innovation Advisory Committee meeting on August 20-21. Duffy warned that prediction markets are susceptible to manipulation and challenged the regulatory posture of newer platforms. Robinhood CEO Vlad Tenev also attended. The dispute centers on self-certification standards, surveillance rules, and whether event-contract platforms operate with adequate market integrity safeguards.
Duffy's platform as the most combative voice at the advisory meeting gives CME Group leverage to push stricter self-certification and surveillance rules. Those requirements would favor incumbent exchanges with in-house compliance teams. For Kalshi and Polymarket US, that means longer launch timelines and higher costs on every new contract.
The personal escalation between Duffy and Kalshi operators makes compromise on standards harder. Better Markets' endorsement of Duffy's manipulation concerns adds outside credibility that congressional ban advocates can cite. The advisory committee's open division means rulemaking may emerge fractured with no predictable standard.
