CFTC

The CFTC derives its jurisdiction over prediction markets from the Commodity Exchange Act (CEA), which covers agreements on excluded commodities — a category that includes financial and economic indexes as well as occurrence-based event contracts. When a platform registers as a Designated Contract Market, it falls under comprehensive CFTC oversight covering product approval, market surveillance, capital requirements, and customer fund protection. This federal framework preempts state gambling laws, which is the legal basis for Kalshi and Polymarket resisting enforcement actions by state gaming regulators in Illinois, Connecticut, Nevada, and Arizona in 2025 and 2026. Platforms operating offshore or without CFTC registration, such as the original version of Decentralized Prediction Market Polymarket, do not enjoy this federal shield and face separate legal exposure.

After years of cautious engagement, the CFTC accelerated its rulemaking posture in 2025. Acting Chair Caroline Pham signaled in early 2025 that the agency would resolve legal uncertainty around event contracts. By March 2026, the CFTC had published proposed rules specifying which Event Contract types are permissible on licensed exchanges and which — such as contracts tied to officiating outcomes or individual player injuries — would be prohibited. Separately, the Enforcement Division issued an advisory in early 2026 warning against insider trading in event contract markets, followed by the first civil enforcement actions against political candidates who traded on their own election outcomes and a military service member who allegedly used classified intelligence. These actions signal that Anti-Money Laundering and market-integrity obligations apply with full force to regulated prediction markets.

Trading on a CFTC-regulated exchange provides concrete protections absent from unregulated alternatives. Customer funds must be held in segregated accounts under Custody rules enforced by a Derivatives Clearing Organization (DCO), reducing Counterparty Risk. Platforms must publish rulebooks, maintain audit trails, and cooperate with CFTC examinations. KYC identity verification is mandatory, and Anti-Money Laundering programs require suspicious activity reporting. Geofencing controls restrict access by residents of jurisdictions where CFTC authority is contested. For traders, these requirements translate into greater confidence that markets are fairly run and that funds can be recovered in the event of platform insolvency — the key distinction from unregulated offshore venues.
