Key takeaway: The CFTC has become the de facto US regulator for prediction markets since 2022. Platforms must register as Designated Contract Markets (DCMs) or face enforcement. Kalshi is the only fully compliant platform; Polymarket settled and geo-blocks US users.
Should you be trading prediction markets within the United States — or thinking about starting — grasping the CFTC's role in prediction markets is absolutely essential. This regulatory body dictates which contracts remain legal to trade, which venues can offer them, and what operational standards apply.
What is the CFTC?
The Commodity Futures Trading Commission represents the primary federal regulator overseeing commodity futures, options, and derivatives contracts across US markets. Given that prediction market instruments behave much like binary options contracts, they come under CFTC authority whenever they are made available to Americans.
Key CFTC Enforcement Actions
Polymarket (January 2022)
Polymarket reached a settlement with the CFTC for $1.4 million following its operation of an unlicensed event contract exchange. The settlement's principal components were:
- $1.4M financial penalty imposed by regulators
- Commitment to retire markets that failed to meet compliance standards
- Implementation of geographic restrictions preventing American customers from accessing the platform directly
Following this settlement, Polymarket has redirected efforts toward international expansion while investigating potential compliance mechanisms for US operations.
Kalshi vs. CFTC (2023-2024)
Kalshi, holding DCM registration with the CFTC, initiated legal proceedings against the agency after it denied approval for contracts tied to legislative outcomes. This pivotal ruling determined that the CFTC lacked authority to categorically prohibit event contracts merely because they reference political elections — representing a significant breakthrough for market participants. The DC Circuit's decision unlocked possibilities for expanded event contract offerings across the sector.
Nadex and Other Platforms
Nadex (North American Derivatives Exchange) has provided CFTC-regulated binary options contracts for an extended period, encompassing certain event-linked instruments. Their operational framework illustrates that compliant prediction markets remain achievable within the current regulatory environment.
What Makes a Prediction Market Legal in the US?
For a platform to legitimately provide prediction market instruments to American participants, it must satisfy these requirements:
- Secure DCM registration through the CFTC
- Meet Core Principles standards — encompassing 23 distinct obligations addressing market monitoring, financial safeguards, and participant protections
- Secure contract authorisation — submitting individual contract specifications for CFTC review and non-objection
- Deploy KYC/AML safeguards — establishing customer identification and financial crime prevention systems
The "Gaming" Exception
Under the Commodity Exchange Act (CEA), event contracts touching upon "gaming" activities face statutory prohibition — a concept the CFTC construes expansively. This restriction explains why prediction markets centred on sporting events remain legally contentious. Historically, the CFTC maintained that sports-linked event contracts qualify as gaming activities, though Kalshi's judicial victory has complicated this interpretation considerably.
What Happens if You Trade on Unregistered Platforms?
Retail participants themselves encounter limited enforcement exposure — the CFTC pursues platforms rather than individual traders. Nevertheless, participation on unregistered venues introduces substantial risks:
- CFTC safeguards for customer assets do not extend to your account
- Your deposits receive no segregation protections mandated by regulators
- CFTC remedies remain unavailable should the platform become insolvent or engage in misconduct
