Key takeaway: Since 2022, the CFTC has emerged as the primary US regulator overseeing prediction markets. Platforms seeking to operate legally must obtain registration as Designated Contract Markets (DCMs) or risk regulatory action. Kalshi stands as the sole fully-compliant operator; Polymarket agreed to a settlement and restricts access for US-based participants.
Should you be trading prediction markets from within the United States — or thinking about starting — grasping the CFTC's authority over prediction markets is essential. This regulatory body dictates which contracts remain permissible, which venues can offer them, and the operational standards required.
What is the CFTC?
The Commodity Futures Trading Commission serves as the federal regulator governing commodity futures, options, and derivatives markets across the United States. Because prediction market contracts behave much like binary options instruments, they trigger CFTC oversight whenever marketed to American participants.
Key CFTC Enforcement Actions
Polymarket (January 2022)
Polymarket reached a settlement with the CFTC for $1.4 million following its operation as an unlicensed event contract exchange. The settlement's principal provisions encompassed:
- $1.4M financial penalty imposed by the CFTC
- Commitment to retire non-compliant contract offerings
- Implementation of geographic restrictions preventing US-based users from accessing the platform directly
Following this settlement, Polymarket has redirected efforts toward international expansion while investigating potential compliance routes for US re-entry.
Kalshi vs. CFTC (2023-2024)
Kalshi, operating as a registered CFTC DCM, initiated litigation challenging the agency's rejection of its congressional election-based contracts. This pivotal ruling determined that the CFTC lacks authority to impose categorical prohibitions on event contracts merely because they relate to electoral processes — representing a significant breakthrough for the sector. The DC Circuit's decision broadened opportunities for additional event contract varieties to enter the market.
Nadex and Other Platforms
Nadex (North American Derivatives Exchange) has provided CFTC-supervised binary options trading for an extended period, encompassing certain event-related contracts. Their operational framework illustrates that compliant prediction markets remain achievable within the current US regulatory framework.
What Makes a Prediction Market Legal in the US?
Platforms seeking authorisation to provide prediction market contracts to American customers must satisfy these criteria:
- Secure DCM status through formal CFTC registration
- Satisfy Core Principles — encompassing 23 operational standards addressing surveillance capabilities, financial safeguards, and trader protections
- Gain contract authorisation — submitting each proposed contract category for CFTC review and non-objection
- Establish KYC/AML systems — deploying customer identification and financial crime prevention measures
The "Gaming" Exception
Under the Commodity Exchange Act (CEA), event contracts tied to "gaming" activities remain prohibited — a definition the CFTC construes expansively. Consequently, sports-focused prediction markets persist as a contentious regulatory matter. Historically, the CFTC has contended that sports event contracts qualify as gaming; nonetheless, Kalshi's judicial success has complicated this interpretation.
What Happens if You Trade on Unregistered Platforms?
End users encounter comparatively limited exposure — the CFTC pursues platforms rather than individual traders. Nevertheless, participation on unregistered venues carries significant implications:
- CFTC safeguards for customer assets do not apply to your holdings
- Your deposits lack the protection of segregated account requirements
- CFTC remedies become unavailable if the platform collapses or engages in misconduct
