CFTC & Prediction Markets: US Regulatory Guide 2026

The CFTC governs US prediction markets. Learn why Kalshi holds DCM status, why Polymarket blocked US users, and where offshore platforms like GADUIN fit.

The US prediction market industry has transformed significantly over the past five years, driven by regulatory clarity, landmark court rulings, and a wave of new market participants. At the centre of this transformation stands the Commodity Futures Trading Commission (CFTC) — the federal agency that determines which event contract platforms may operate legally in the United States and under what conditions.

This guide maps the current regulatory landscape: the CFTC’s statutory authority over event contracts, Kalshi’s position as the benchmark US-regulated platform, the compliance history of Polymarket, the evolving 2026 rulemaking framework, and the legal posture of offshore platforms for non-US traders.

What Is the CFTC and Why Does It Govern Event Contracts?

The Commodity Futures Trading Commission is an independent federal agency established by Congress in 1974 to regulate US derivatives markets — commodity futures, options, and swaps. Event contracts, which pay based on binary outcomes, fall within the CFTC’s jurisdiction because courts and the agency have consistently treated them as derivative instruments under the Commodity Exchange Act (CEA).

Event Contracts as CFTC-Regulated Derivatives Under the Commodity Exchange Act

The Commodity Exchange Act defines “commodity” broadly, and event contracts — also called prediction market contracts or binary event contracts — fit within that definition when they reference economic or financial outcomes. Congress specifically addressed event contracts in Section 5c(c)(5)(C) of the CEA, which grants the CFTC authority to prohibit contracts that are contrary to the public interest or that involve activity already regulated under a separate federal statute — such as gambling laws or securities law.

This provision has been the central legal battleground for US prediction market operators for over a decade. Platforms seeking to offer event contracts to US customers must either obtain CFTC registration as a Designated Contract Market, or accept that their contracts may be deemed unlawful under US law.

The Designated Contract Market (DCM) Designation — What It Means

A Designated Contract Market is a CFTC-registered exchange. To obtain DCM status, an exchange must satisfy 23 core principles covering financial safeguards, market surveillance, participant protections, and operational standards. DCM designation gives an exchange the legal authority to offer regulated derivatives — including event contracts — to US retail and institutional participants.

The DCM framework imposes ongoing obligations: mandatory segregation of customer funds, real-time market surveillance, reporting to the CFTC, and a clearly defined rulebook for settlement and dispute resolution. For traders, this framework means the exchange operates under federal oversight and its rules are CFTC-approved.

Kalshi — The US-Regulated Prediction Market Benchmark

Kalshi (KalshiEX LLC) is currently the most prominent US-regulated event contract exchange. It is the reference point for what CFTC-compliant prediction market operation looks like in practice, and its regulatory journey has shaped how the industry defines the path to operating within the US framework.

How Kalshi Obtained DCM Status (and What the Process Required)

According to CFTC Press Release 8302-20, the CFTC granted Kalshi DCM designation in 2020, making it the first entity to receive DCM status specifically for event contracts. The designation followed a multi-year application process that required demonstrating compliance with all 23 DCM core principles, sustained engagement with CFTC staff, and the establishment of operational infrastructure consistent with a regulated exchange.

Obtaining DCM status is not a one-time approval — it is an ongoing compliance obligation. Kalshi must maintain the financial safeguards, surveillance systems, and governance structures the CFTC requires of any registered exchange.

What CFTC Oversight Means for Traders: Segregated Funds, Market Surveillance, Transparent Settlement

DCM status translates into concrete protections for market participants. Customer funds held on a CFTC-designated exchange must be kept in segregated accounts, separated from the exchange’s own operational capital. This structure reduces counterparty risk compared with platforms operating without such requirements.

Market surveillance under CFTC oversight means the exchange must monitor for manipulation, wash trading, and other practices that distort market outcomes. Settlement criteria — the data and standards used to determine contract outcomes — must be clearly defined in the exchange’s CFTC-approved rulebook, which is publicly available.

Kalshi’s expansion into politically sensitive and sports-related markets has been contested. The platform sought to offer event contracts on US congressional election outcomes — a category the CFTC initially opposed as contrary to the public interest under Section 5c(c)(5)(C). Litigation followed, and the legal question of where event contracts end and unlawful gambling begins has proceeded through federal courts.

In a significant ruling (KalshiEX LLC v. Flaherty, No. 25-1922 (3d Cir. Apr. 6, 2026)), a federal appeals court addressed the intersection of state gaming regulation and federal commodity law. The court affirmed a preliminary injunction (2-1), finding the CEA likely preempts state gambling law as applied to sports-related event contracts on a CFTC-designated market — a ruling with broad implications for the range of event categories that DCMs can legally offer.

Why Polymarket and Others Historically Blocked US Users

Polymarket is among the most widely recognised prediction market platforms globally. Its regulatory history in the United States illustrates the compliance exposure platforms face when offering event contracts without CFTC registration.

The 2022 CFTC Enforcement Action Against Polymarket

In January 2022, the CFTC issued an enforcement order against Blockratize, Inc. (Polymarket’s then-operator), finding that the platform had operated unregistered binary options contracts and failed to register as a designated contract market or swap execution facility. The order resulted in a $1.4 million civil monetary penalty. Following this action, Polymarket ceased offering its platform to US persons and implemented geoblocking for US-based users.

This enforcement action established a clear precedent: offering binary event contracts to US participants without CFTC registration violates the Commodity Exchange Act, regardless of the platform’s technical architecture or blockchain underpinnings.

Polymarket’s Return: US Operations via CFTC-Regulated DCM (2025–2026)

Since the 2022 settlement, Polymarket has pursued a pathway to re-enter the US market through CFTC compliance. As of 2025–2026, the platform has made public steps toward obtaining or partnering with a CFTC-registered entity to offer event contracts to US participants under a regulated structure. This evolution reflects a broader industry shift: established prediction market platforms increasingly treat CFTC registration as the prerequisite for sustainable US market access, rather than an obstacle to route around.

How Offshore Platforms Exclude US Persons — Geoblocking and KYC

Platforms that operate as offshore exchanges — outside US jurisdiction — typically exclude US persons through a combination of IP-based geoblocking, identity verification (KYC) processes that screen for US nationality or residency, and Terms of Service that expressly prohibit participation by US persons. These measures reflect the legal reality that serving US participants with unregistered event contracts creates CFTC enforcement exposure.

No geoblocking or KYC system provides absolute guarantees. Users who circumvent these controls — through VPNs or misrepresentation during identity verification — bear personal legal risk. Platform-side exclusion mechanisms are a compliance tool, not a waiver of a user’s own legal obligations under applicable law.

The Evolving CFTC Framework: 2026 Proposed Rule

The regulatory landscape for event contracts in the US is not static. In June 2026, the CFTC published a Notice of Proposed Rulemaking (Federal Register Doc. 2026-11854, June 12, 2026) that proposes to codify the analytical framework for evaluating event contract permissibility — shifting from ad hoc Commission decisions toward a structured, rule-based process.

The Three-Step Analytical Framework for Event Contract Permissibility

The June 2026 proposed rule (Federal Register Doc. 2026-11854) outlines a three-step analytical framework for determining whether a proposed event contract is permissible under Section 5c(c)(5)(C):

  1. Activity category check: Does the contract involve gaming, activity unlawful under federal or state law, or activity regulated by another federal agency?
  2. Public interest test: Is the contract contrary to the public interest — for example, because it creates incentives for criminal activity, manipulates voters, or introduces systemic risk?
  3. Exemption analysis: Even where a concern is identified, does the contract serve a sufficient hedging, price-discovery, or risk-management function to warrant a specific exemption?

If adopted in final form, this framework would give platform operators clearer advance guidance on which event categories are viable under CFTC regulation. It also signals that the CFTC intends to maintain active oversight of the event contract product category, rather than deferring entirely to DCM self-regulation.

A recurring issue in the US event contract landscape is the collision between federal commodity law and state gaming statutes. Multiple states — including Nevada, New Jersey, and Maryland — issued cease-and-desist orders against Kalshi, arguing that event contracts on election and sports outcomes constitute gambling under state law and should be regulated at the state level. Kalshi filed for declaratory judgment and preliminary injunctions against these states to contest the enforcement actions.

Federal courts have consistently held that CFTC jurisdiction preempts conflicting state gambling regulation when the product is a legitimate commodity derivative. The April 2026 Third Circuit ruling (KalshiEX LLC v. Flaherty, No. 25-1922 (3d Cir. Apr. 6, 2026)) reinforced this preemption doctrine, affirming a preliminary injunction (2-1) finding the CEA likely preempts state gambling law as applied to sports-related event contracts on a CFTC-designated market.

Public Comment Period and What’s Next for Platform Operators

The June 2026 proposed rule is open for public comment through July 27, 2026. Platform operators, legal practitioners, and market participants are invited to submit responses addressing the scope of the permissibility framework, the definitions of “gaming” and “unlawful activity,” and the process for no-action relief during the rulemaking period.

Final adoption of the rule is anticipated in late 2026 or 2027, pending CFTC review of submitted comments. For platform operators, the practical implication is straightforward: the CFTC is building a more transparent, rule-based pathway for event contract product approval — and platforms that engage constructively with this process are better positioned for sustainable operation within the US regulatory framework.

Offshore Event Contract Platforms and Access for Non-US Traders

The majority of global event contract trading volume flows through platforms that operate outside the United States. For non-US traders, these platforms represent the primary access point for prediction market exposure. Understanding what “offshore” means — legally and practically — is foundational to informed participation.

What “Offshore” Means Legally and Practically

“Offshore” in the context of event contract exchanges refers to platforms incorporated and operated outside US jurisdiction — typically in jurisdictions such as the British Virgin Islands, Seychelles, Gibraltar, or Malta, which permit event contract or prediction market activities under local regulatory frameworks. These platforms are not registered with the CFTC, do not hold DCM status, and are not legally authorised to serve US persons.

For non-US traders, the legal status of an offshore platform depends entirely on the laws of the trader’s own jurisdiction. In many countries, accessing an offshore event contract exchange is straightforwardly lawful for retail participants. In others, there may be restrictions on certain product types, capital controls, or local licensing requirements. The applicable law is the law of the user’s jurisdiction — not US law, and not the jurisdiction of the exchange’s incorporation.

User Responsibility and Jurisdictional Due Diligence

Using any financial platform — regulated or offshore — carries legal and financial responsibility. Traders on offshore event contract exchanges should confirm that accessing such platforms is lawful under the laws of their own country or jurisdiction, review the platform’s Terms of Service carefully (particularly provisions concerning eligibility and exclusions), and understand that offshore platforms are not subject to the same participant protection frameworks as CFTC-designated exchanges. There is no federal segregated-funds requirement, no CFTC market surveillance mandate, and no US regulatory recourse channel.

This does not mean offshore platforms are unregulated in all respects — many operate under the laws of their home jurisdiction — but the regulatory framework is materially different from CFTC oversight, and the protections available to participants differ accordingly.

Where GADUIN Fits in the Global Event Contract Landscape

GADUIN is an offshore event contracts exchange operating in the transport delay niche — offering markets on flight delays, train disruptions, and maritime incidents, with settlement in USDT. It is not registered with the CFTC, does not hold DCM status, and does not accept US persons as participants.

GADUIN as an Offshore Event Contracts Exchange

GADUIN’s product focus is transport event contracts: outcomes such as whether a specific flight will be delayed by 15 or more minutes, whether a train service will arrive within schedule, or whether a container vessel will arrive outside its expected window. Positions are settled in USDT based on verifiable real-world data — flight status APIs, rail operator records, port authority data.

Like other offshore platforms, GADUIN operates outside CFTC jurisdiction. Access for US persons is restricted through KYC verification and Terms of Service in accordance with applicable regulatory requirements. For non-US traders seeking exposure to transport delay outcomes — or looking to take a position on the probability of travel disruption — GADUIN provides a specialised event contract market that is not replicated on CFTC-regulated US exchanges.

GADUIN’s availability is subject to the laws of each user’s jurisdiction. The platform’s Terms of Service define eligibility criteria, and each user bears independent responsibility for confirming that their participation complies with applicable local law. GADUIN is not a licensed or regulated platform in the United States and is not available to US persons.

As with all offshore financial platforms, access does not imply legal clearance. Each trader is responsible for understanding the rules that govern their participation, including applicable tax treatment of any trading outcomes.

Frequently Asked Questions

Is it legal to use offshore prediction markets as a non-US user?

It depends on your jurisdiction. In many countries, accessing an offshore event contract exchange is lawful for retail participants. In others, there may be restrictions on certain product types. US law expressly prohibits US persons from using unregistered event contract platforms. For all other users, the relevant legal standard is the law of their own country — not US law, and not the jurisdiction where the exchange is incorporated.

What is a CFTC Designated Contract Market?

A Designated Contract Market (DCM) is an exchange registered with the US Commodity Futures Trading Commission under the Commodity Exchange Act. DCM status authorises the exchange to offer regulated derivatives, including event contracts, to US participants. It requires ongoing compliance with 23 CFTC core principles covering financial safeguards, market surveillance, and governance. Kalshi is currently the most prominent example of a DCM offering event contracts.

Why can’t US persons use Polymarket’s international platform?

Following a January 2022 CFTC enforcement order against Polymarket’s then-operator (Blockratize, Inc.), the platform ceased offering its services to US persons and implemented geoblocking for US users. The enforcement action found that the platform had operated unregistered binary options contracts in violation of the Commodity Exchange Act. US persons remain excluded from the international version of the platform; US-facing access is only legally possible through a CFTC-registered entity.

Is GADUIN regulated by the CFTC?

No. GADUIN is an offshore event contracts exchange and is not registered with or regulated by the CFTC. It does not hold Designated Contract Market status and does not accept US persons as participants. Users outside the US should consult the laws of their own jurisdiction before using the platform.
