Quick Answer

Polymarket is legal and CFTC-approved in the United States since late 2025. Polymarket US (QCX LLC) requires full KYC for US traders. There are now 13 federally regulated prediction market platforms available to US users. However, some states are challenging federal jurisdiction — 11 states introduced prediction market legislation in 2026. In most other countries, Polymarket is accessible without restrictions. Always check your local laws before trading.

Polymarket Legality in the United States

The legal status of prediction markets in the US underwent major changes in 2025-2026. Here's the current state as of April 2026:

Current Status (April 2026)

Polymarket is now CFTC-approved for US users. In late 2025, Polymarket launched Polymarket US (QCX LLC), a CFTC-regulated entity that self-certified new market rules. US users must complete full KYC (government ID, SSN, proof of residency) to trade on regulated event contracts.

There are now 13 federally regulated prediction market platforms available to US users, including Polymarket, Kalshi, Robinhood, FanDuel Predicts, DraftKings, and Fanatics Markets.

April 2026 Regulatory Developments

Important: Federal vs. State Conflict

While the CFTC approves prediction markets at the federal level, some states are actively challenging this. Prediction markets currently operate in a hybrid legal zone — federally framed as CFTC event contracts, but exposed to state gambling enforcement and ongoing litigation. The CFTC maintains it has exclusive jurisdiction, but state courts have issued mixed rulings. Using a VPN to bypass geographic restrictions violates platform terms of service.

Polymarket's Legal History Timeline

Polymarket's journey from an unregulated startup to a CFTC-approved platform has been shaped by enforcement actions, legal battles, and a shifting political landscape. This comprehensive timeline covers every major legal milestone.

2020: Launch and Early Growth

Polymarket was founded by Shayne Coplan in 2020 as a decentralized prediction market built on the Polygon (formerly Matic) blockchain. The platform allowed users to trade binary outcome contracts on real-world events — from COVID-19 vaccine timelines to political outcomes. At launch, Polymarket operated without CFTC registration, relying on its decentralized architecture and the regulatory gray area surrounding crypto-native platforms. During its first year, the platform attracted modest volume, primarily from crypto-native users familiar with DeFi protocols.

2021: CFTC Investigation Begins

By mid-2021, Polymarket's growing volume — particularly on politically sensitive markets — attracted the attention of the Commodity Futures Trading Commission. The CFTC opened a formal investigation into whether Polymarket was operating as an unregistered swap execution facility or designated contract market. The investigation focused on whether Polymarket's binary outcome contracts constituted "event contracts" or "swaps" under the Commodity Exchange Act (CEA), which would require CFTC registration. During this period, Polymarket continued operating but began engaging legal counsel to navigate the regulatory scrutiny.

January 2022: The $1.4M CFTC Settlement

On January 3, 2022, Polymarket reached a settlement with the CFTC. The key terms included:

2022-2023: The Offshore Pivot

Following the CFTC settlement, Polymarket implemented geofencing to block US-based IP addresses. The platform restructured its operations to serve international users, relocating key corporate functions offshore. Despite the settlement, Polymarket continued to grow its international user base significantly during this period. The platform introduced new market categories — including sports, entertainment, and science — while maintaining its core political prediction markets. Polymarket raised $45 million in a Series B funding round in May 2023, led by Founders Fund (Peter Thiel's venture firm), signaling continued investor confidence despite the regulatory setback.

2023-2024: The Kalshi Lawsuit and Legal Precedent

While Polymarket operated offshore, the legal landscape for prediction markets was being reshaped by Kalshi's lawsuit against the CFTC. Kalshi, a CFTC-registered Designated Contract Market (DCM), had applied to list election-based event contracts. When the CFTC rejected Kalshi's application in 2023, Kalshi sued in the U.S. District Court for the District of Columbia. In September 2024, Judge Jia Cobb ruled in Kalshi's favor, finding that election contracts were not "gaming" or "activity unlawful under state law" and could therefore be listed on a regulated exchange. The CFTC's emergency motion to stay the ruling was denied by the D.C. Circuit Court of Appeals. This ruling created the legal precedent that Polymarket would later use to re-enter the US market.

November 2024: The Election Surge and DoJ Subpoena

The 2024 US presidential election was a watershed moment for prediction markets. Polymarket processed over $3.5 billion in trading volume on election-related markets, dwarfing all previous records. The platform's odds were cited by major news outlets (CNN, Fox News, Bloomberg, the New York Times) as a real-time indicator of election sentiment. However, the election also brought renewed legal scrutiny. In November 2024, the Department of Justice issued a subpoena to Polymarket founder Shayne Coplan. FBI agents reportedly visited Coplan's New York City apartment. The investigation was reportedly focused on whether Polymarket had adequately blocked US users following the 2022 settlement, not on the legality of prediction markets themselves. Polymarket publicly stated it was cooperating with the investigation.

January 2025: Polymarket Announces US Return

In January 2025, Polymarket announced plans to re-enter the US market through a new regulated entity: QCX LLC. The entity would operate as Polymarket US, a CFTC-compliant platform requiring full KYC verification for all US users. The announcement came in the wake of the Kalshi ruling and a more favorable political environment under the new administration. Polymarket hired a dedicated compliance team and engaged with the CFTC on self-certification of market rules. The platform began onboarding US users in late 2025.

February 2026: CFTC ANPRM on Event Contracts

On February 28, 2026, the CFTC published an Advanced Notice of Proposed Rulemaking (ANPRM) in the Federal Register, specifically addressing the regulation of event contracts. This was the first formal step toward a comprehensive regulatory framework for prediction markets. The ANPRM solicited public comment on 58 specific questions, covering topics including: which types of events should be eligible for regulated trading, how platforms should handle market integrity and manipulation, appropriate position limits for event contracts, and the relationship between federal regulation and state gambling laws. The comment period was set for 90 days.

March 2026: State-Level Enforcement Escalates

March 2026 saw a rapid escalation of state-level enforcement actions:

State-by-State Legal Status

The patchwork of state-level regulation makes it essential for US-based traders to understand the legal landscape in their specific state. Below is a detailed breakdown of prediction market legality across major US states as of April 2026.

Note on Federal Preemption

The CFTC maintains that it has exclusive federal jurisdiction over event contracts. However, several states have challenged this position, arguing that prediction markets constitute gambling under state law. The question of federal preemption is currently being litigated in multiple courts. Until a definitive ruling is issued, the legal landscape remains uncertain at the state level.

International Legal Landscape

Outside the United States, prediction market regulation varies dramatically. Some jurisdictions offer a clear legal framework, while others present significant ambiguity or outright prohibition. Here is a country-by-country analysis of major markets.

United Kingdom

The UK regulates prediction markets primarily through the Gambling Act 2005, enforced by the UK Gambling Commission. Under this framework, prediction markets are classified as a form of betting. Licensed operators like Betfair and Smarkets offer legally compliant prediction-style markets. Polymarket itself is not licensed by the UK Gambling Commission, meaning it operates in a gray area — accessible to UK users but without the consumer protections that licensed operators must provide (segregated client funds, dispute resolution, responsible gambling tools). The FCA (Financial Conduct Authority) has not classified prediction market tokens as regulated financial instruments, though this could change if the Treasury extends its crypto regulatory framework. UK users face minimal enforcement risk but should be aware they lack regulatory protection when using unlicensed platforms.

European Union

EU regulation of prediction markets is fragmented across member states. The Markets in Crypto-Assets Regulation (MiCA), which took full effect in December 2024, primarily targets crypto-asset issuers and service providers. MiCA does not specifically address prediction markets, but platforms operating on blockchain infrastructure (like Polymarket on Polygon) may fall under its scope if they are deemed to provide crypto-asset services to EU residents. Key considerations for EU users:

In practice, Polymarket remains accessible across most EU member states, and individual enforcement against users is extremely rare. However, MiCA compliance requirements could force Polymarket to register as a Crypto-Asset Service Provider (CASP) or restrict EU access in the future.

Canada

Canada's gambling regulation is primarily provincial. The Criminal Code of Canada (Section 206) prohibits operating a lottery scheme without provincial authorization, but "lottery scheme" is broadly interpreted. Since the 2021 amendment to the Criminal Code (Bill C-218, the Safe and Regulated Sports Betting Act), provinces have expanded online gambling. Prediction markets fall into a regulatory gray area — they are not explicitly authorized or prohibited at the federal level. Provinces like Ontario (regulated by the Alcohol and Gaming Commission of Ontario, AGCO) have established iGaming frameworks, but these do not specifically address prediction markets. Canadian users can access Polymarket without restriction, though profits are taxable under CRA guidelines.

Australia

Australia regulates online gambling through the Interactive Gambling Act 2001 (IGA), enforced by the Australian Communications and Media Authority (ACMA). The IGA prohibits offering certain "interactive gambling services" to Australian residents. Prediction markets could fall under this prohibition if classified as gambling. Sportsbet and other licensed operators offer some prediction-style markets. Polymarket is accessible from Australia but is not licensed by any Australian regulator. The ACMA has focused enforcement on offshore sports betting operators rather than crypto-based prediction platforms, but this could change. Australian users should also be aware that the Australian Taxation Office (ATO) treats gambling winnings as non-taxable (unlike the US), but regular or professional prediction market trading may be classified as assessable income.

Japan

Japan has some of the most restrictive gambling laws in the developed world. The Penal Code (Articles 185-187) broadly prohibits gambling, with narrow exceptions for government-authorized activities (horse racing via JRA, boat racing, bicycle racing, lottery). Prediction markets are not among the authorized exceptions. Japan's crypto regulations (Payment Services Act, Financial Instruments and Exchange Act) focus on exchanges and token issuers, not prediction market users. While Polymarket does not actively block Japanese IP addresses, using the platform could technically violate Japanese gambling law. Enforcement against individual users for overseas online gambling is rare but not unprecedented. Japanese users face the highest legal risk among major developed countries.

India

India's gambling regulation is a state-level matter under the Constitution's Seventh Schedule. The central Public Gambling Act of 1867 is outdated and does not address online gambling. State-level legal status varies enormously:

India's crypto regulatory framework (30% tax on crypto gains under the 2022 Finance Act, plus 1% TDS on crypto transactions) applies to prediction market activity. Polymarket is accessible from most of India, but the legal status depends on the user's specific state. The distinction between "games of skill" (generally legal) and "games of chance" (generally prohibited) is key — prediction markets could arguably fall into either category depending on the analysis used.

Singapore

Singapore's Remote Gambling Act 2014 (RGA) broadly prohibits remote (online) gambling. The Gambling Regulatory Authority of Singapore (GRA) enforces the RGA aggressively. Using an overseas gambling service is an offense under Section 8 of the RGA, punishable by a fine of up to S$10,000 or imprisonment of up to 6 months. Polymarket is technically prohibited in Singapore. While enforcement against individual users has been limited, Singapore's strict regulatory environment makes it one of the higher-risk jurisdictions for prediction market participation.

United Arab Emirates

The UAE has a complex relationship with crypto and gambling. Federal Law No. 3 of 1987 (Penal Code) prohibits gambling. However, the UAE — particularly Dubai and Abu Dhabi — has positioned itself as a global crypto hub, with the Virtual Assets Regulatory Authority (VARA) in Dubai and the Financial Services Regulatory Authority (FSRA) in Abu Dhabi's ADGM free zone regulating crypto assets. Prediction markets fall into a gray area: the crypto infrastructure is legal, but the betting function may not be. Polymarket is accessible from the UAE, and enforcement against individual users for using offshore platforms has not been reported. However, the legal risk is non-trivial, particularly as UAE regulators expand their oversight of virtual asset activities.

VPN Considerations

Using a VPN to Access Polymarket

Users in restricted jurisdictions sometimes use VPNs to access Polymarket. This carries significant risks:

CFTC Regulatory Framework Explained

Understanding how prediction markets are regulated in the US requires understanding the role and authority of the Commodity Futures Trading Commission. This section breaks down the regulatory framework that governs platforms like Polymarket, Kalshi, and their competitors.

What Is the CFTC?

The Commodity Futures Trading Commission (CFTC) is an independent federal regulatory agency created by Congress in 1974. It regulates the US derivatives markets, including futures, swaps, and options on commodities and financial products. The CFTC's authority comes from the Commodity Exchange Act (CEA), originally passed in 1936 and amended multiple times since. The CFTC's five commissioners are appointed by the President and confirmed by the Senate. The current chair (as of April 2026) has signaled a more permissive approach to innovation in derivatives markets, including prediction markets.

What Are Event Contracts?

Event contracts are a specific type of derivative where the payout is determined by whether a specified real-world event occurs. Under the CEA, the CFTC has jurisdiction over event contracts. Key characteristics:

Designated Contract Markets (DCMs) vs. Unregulated Platforms

The distinction between regulated and unregulated platforms is critical for understanding the legal landscape:

FeatureDCM (e.g., Kalshi)Self-Certified Entity (e.g., Polymarket US / QCX LLC)Unregulated Platform (e.g., pre-2025 Polymarket)
CFTC RegistrationFull DCM registrationOperates under CFTC framework via self-certificationNone — operates offshore

US User AccessYes — with KYCYes — with full KYC (government ID, SSN)No — US users geofenced
Market ApprovalMust submit each market for CFTC approval or self-certificationSelf-certifies market rules within CFTC frameworkLists any market without approval
Bankruptcy ProtectionCustomer funds may be recoverable under CFTC Part 190 bankruptcy rulesSome protections via CFTC frameworkNo bankruptcy protections — crypto deposits at risk

The 2024 Court Ruling and Its Impact

The September 2024 federal court ruling in Kalshi v. CFTC was the pivotal moment for prediction market regulation. Judge Jia Cobb of the U.S. District Court for the District of Columbia ruled that:

The D.C. Circuit Court of Appeals denied the CFTC's emergency motion to stay the ruling, allowing Kalshi to immediately list election contracts. This ruling fundamentally changed the regulatory equation — it established that the CFTC cannot categorically ban prediction markets on political events, and it opened the door for Polymarket and others to re-enter the US market.

The ANPRM Process and What It Means

The CFTC's February 2026 Advanced Notice of Proposed Rulemaking (ANPRM) is the first step in what could become a comprehensive regulatory framework for prediction markets. Here's how the ANPRM process works:

  1. ANPRM (Current Stage): The CFTC solicits broad public input on key questions. This is a preliminary inquiry — not a proposed rule.
  2. Notice of Proposed Rulemaking (NPRM): Based on ANPRM comments, the CFTC would draft a proposed rule and publish it for a formal comment period (typically 60-90 days).
  3. Final Rule: After considering comments, the CFTC issues a final rule with the force of law.
  4. Implementation: Platforms and market participants comply with the new rules within a specified timeframe.

The ANPRM's 58 questions cover the most contentious issues: which event types should be eligible, how to prevent manipulation, appropriate position limits, the role of blockchain technology, and how to manage the federal-state jurisdictional conflict. A final rule could take 18-36 months from the ANPRM stage, meaning comprehensive regulation may not be in place until 2028.

Polymarket vs Regulated Platforms: Legal Comparison

With 13 federally regulated prediction market platforms now available to US users, understanding the legal differences between platforms is essential. Each platform operates under a different regulatory model, offering different levels of legal protection to traders.

What Happens If a Platform Fails?

This is one of the most important legal distinctions between platforms:

Legal Risks for Individual Traders

Most regulatory enforcement has targeted platforms, not individual users. However, traders should be aware of several legal obligations and risks.

Can You Get in Trouble for Trading on Polymarket?

In the United States, trading on Polymarket US (QCX LLC) — the CFTC-approved platform — is legal for users who complete KYC. The risk profile differs based on your situation:

Tax Reporting Obligations

This is the most concrete legal obligation for prediction market traders. In the US:

IRS Cryptocurrency Reporting Requirements

Because Polymarket operates on the Polygon blockchain and uses USDC, additional crypto-specific reporting requirements apply:

FBAR Implications for Non-US Users

US persons (citizens and residents) with financial accounts in foreign countries exceeding $10,000 in aggregate value at any point during the year must file a Report of Foreign Bank and Financial Accounts (FBAR) — FinCEN Form 114. The question of whether Polymarket positions constitute a "foreign financial account" for FBAR purposes is unresolved. However, if you hold USDC in a Polymarket wallet controlled by a non-US entity, conservative tax advisors may recommend filing an FBAR. Failure to file carries penalties of up to $12,909 per violation (non-willful) or the greater of $129,210 or 50% of the account balance (willful).

Potential Enforcement Scenarios

While no individual retail traders have been charged for prediction market activity, the following scenarios represent potential enforcement risks:

The Insider Trading Question

The March 30, 2026 report that the Department of Justice is investigating whether prediction market bets could violate insider trading laws opened a new chapter in prediction market regulation. This investigation has significant implications for all prediction market users.

What the DOJ Investigation Covers

According to CNN's reporting, federal prosecutors are examining whether traders with non-public information about real-world events have used prediction markets to profit illegally. The investigation reportedly focuses on several categories:

How Insider Trading Law Applies to Prediction Markets

Traditional insider trading law under the Securities Exchange Act of 1934 (Section 10(b) and Rule 10b-5) applies to "securities." The central legal question is whether event contracts on prediction markets qualify as securities. If they do, the full apparatus of insider trading law — including criminal penalties of up to 20 years in prison and fines of up to $5 million for individuals — would apply.

Even if event contracts are not classified as securities, the CFTC has its own anti-manipulation authority under CEA Section 9(a)(2), which prohibits "manipulating or attempting to manipulate the price of any commodity in interstate commerce." The CFTC's manipulation standard could apply to prediction market trading based on non-public information.

The STOCK Act and Congressional Trading

The Stop Trading on Congressional Knowledge (STOCK) Act, passed in 2012, prohibits members of Congress and their staff from trading on material, non-public information obtained through their official duties. The STOCK Act primarily targets securities trading, but its principles are directly relevant to prediction markets. A congressional staffer who trades on a prediction market based on advance knowledge of legislation, executive action, or policy decisions could potentially violate both the STOCK Act and general insider trading law. As of April 2026, no charges have been filed under this theory, but the DOJ investigation reportedly includes this scenario.

Polymarket's Market Manipulation Policies

Polymarket's Terms of Service prohibit market manipulation, wash trading, and trading based on material non-public information. The platform employs surveillance tools to detect abnormal trading patterns. However, the decentralized nature of blockchain transactions — and the fact that the international Polymarket platform does not require KYC — makes enforcement challenging. On Polymarket US (QCX LLC), which requires full KYC, the platform can identify traders and cooperate with law enforcement. In several high-profile instances during the 2024 election, Polymarket flagged suspicious trading activity to regulators. The DOJ's subpoena of Polymarket founder Shayne Coplan in November 2024 may have been partly motivated by seeking access to platform trading data.

What This Means for Regular Traders

For typical retail prediction market users who trade on publicly available information, the insider trading investigation poses minimal direct risk. The investigation targets individuals who possess and trade on material non-public information — information that is not publicly available and would, if made public, likely affect market prices. Trading based on your own analysis of publicly available data (polls, news, expert opinions) is not insider trading. However, the investigation signals that prediction markets are being taken seriously as financial instruments by prosecutors — which, paradoxically, also validates their legal legitimacy.

Notable Legal Cases & Enforcement

The legal history of prediction markets is being written in real time through enforcement actions and lawsuits. Here are the most significant cases and their implications.

This table reflects general accessibility as of April 2026. Regulations change frequently. Always verify the current legal status in your jurisdiction before trading on any prediction market platform. This guide is for informational purposes only and does not constitute legal advice.

Are Prediction Markets Gambling?

One of the central legal questions is whether prediction markets are gambling or financial instruments. The answer affects which regulations apply:

The Financial Instrument Argument

The Gambling Argument

Key Distinction: The 2024 federal court ruling suggested that election contracts are more akin to financial derivatives than gambling, because they serve an informational purpose and their prices reflect genuine market intelligence about real-world outcomes.

Risks & Considerations

Even where Polymarket is accessible, traders should be aware of several risks:

Regulatory Risk

Laws can change. Regulators in any country could decide to restrict prediction markets. If a platform is forced to shut down or restrict access, you may face difficulties withdrawing funds.

No Investor Protection

Unlike regulated exchanges, Polymarket deposits are not insured by FDIC or any government agency. If the platform experiences a security breach or insolvency, there is no guarantee of fund recovery.

Tax Implications

Prediction market profits are generally taxable income in most jurisdictions. In the US, they may be treated as:

Smart Contract Risk

Polymarket operates on the Polygon blockchain using smart contracts. While these have been audited, smart contract bugs are always a possibility in DeFi platforms.

Future of Prediction Market Regulation

Prediction market regulation is at an inflection point. The combination of explosive growth, mainstream adoption, and a more permissive federal stance is colliding with state-level resistance and legitimate concerns about market integrity. Here is where regulation appears to be heading.

The Sports Betting Legalization Parallel

The trajectory of prediction market regulation closely mirrors the path of sports betting legalization following the Supreme Court's 2018 Murphy v. NCAA decision:

Prediction markets in 2026 are roughly where sports betting was in 2019 — federal legality established, early state adoption underway, but a patchwork of state regulations and enforcement actions creating uncertainty. If the pattern holds, we could see 30+ states with explicit prediction market frameworks by 2029-2030.

13 Federally Regulated Platforms and Growing

The rapid growth from 2 platforms (Polymarket, Kalshi) to 13 federally regulated platforms in under two years demonstrates the market's momentum. The entry of established brands — Robinhood (100M+ users), FanDuel (15M+ users), DraftKings (10M+ users), Fanatics — brings significant lobbying power and public legitimacy to the industry. These companies have experience navigating state-by-state regulatory frameworks from their existing businesses, and their lobbying efforts are likely to accelerate state-level legalization.

Bipartisan Support Signals

Prediction markets have attracted unusual bipartisan support in Congress:

Potential Federal Framework

The CFTC's ANPRM is the first step toward a comprehensive federal framework. Based on the questions posed and industry commentary, a final framework is likely to include:

The timeline for a comprehensive framework is likely 2028-2029, given the ANPRM-to-final-rule process and potential Congressional action.

What to Watch

Frequently Asked Questions

Is Polymarket legal in the United States?

Yes, as of late 2025. Polymarket launched Polymarket US (QCX LLC) with CFTC approval. US users must complete full KYC (government ID, SSN) to trade on regulated event contracts. However, some states (Nevada, Massachusetts, Tennessee, Washington) have challenged prediction market legality, and 11 states introduced legislation in 2026. The CFTC maintains it has exclusive federal jurisdiction over event contracts.

Is Polymarket legal in Europe?

Polymarket is generally accessible across Europe. The EU does not have specific bans on prediction markets. The MiCA regulation may affect crypto-based platforms in the future, but as of 2026, European users can access Polymarket without significant restrictions.

Can I get in trouble for using Polymarket?

In most jurisdictions where Polymarket is accessible, individual users have not been targeted by regulators. The regulatory focus has been on the platforms themselves, not individual traders. However, using VPNs to circumvent geographic restrictions could violate both Polymarket's terms and potentially local laws. Tax non-compliance is the most likely source of legal trouble for individual traders.

Is Polymarket regulated by the CFTC?

Yes, as of late 2025. Polymarket US (QCX LLC) operates as a CFTC-approved entity that has self-certified new market rules. The original Polymarket settled with the CFTC in 2022 ($1.4M fine), and the new US entity represents full regulatory compliance. In March 2026, the CFTC issued an Advanced Notice of Proposed Rulemaking to formalize the regulatory framework for all prediction market platforms.

Are prediction markets gambling?

The legal answer depends on jurisdiction. The CFTC has treated some prediction markets as derivatives (financial instruments), not gambling. However, state-level gambling laws may classify them differently. A 2024 federal court ruling supported treating election contracts as financial derivatives rather than gambling.

Do I need to pay taxes on Polymarket profits?

Yes, in most countries prediction market profits are taxable. In the US, they may be classified as capital gains or gambling income depending on how they're treated. Starting in 2025, crypto brokers must issue 1099-DA forms for digital asset transactions. Consult a tax professional for advice specific to your situation and jurisdiction.

What happened in the Polymarket CFTC settlement?

In January 2022, Polymarket (Blockratize, Inc.) settled with the CFTC for $1.4 million. The CFTC alleged Polymarket operated an illegal, unregistered trading facility offering off-exchange event contracts. Polymarket agreed to pay the fine, wind down non-compliant markets, block US users, and pursue regulatory approval. The company did not admit wrongdoing. This settlement ultimately led to the creation of Polymarket US (QCX LLC) as a compliant entity.

Can I use a VPN to access Polymarket from a restricted state or country?

Using a VPN to bypass Polymarket's geographic restrictions violates the platform's Terms of Service. If detected, your account could be suspended and funds frozen. In some jurisdictions (particularly Singapore under the Remote Gambling Act), circumventing geographic restrictions may also violate local law. For the US regulated platform, full KYC requirements make VPN circumvention impractical and detectable.

What is the DOJ insider trading investigation about?

In March 2026, CNN reported that the Department of Justice is investigating whether traders with non-public information about real-world events have illegally profited on prediction markets. The investigation examines whether existing insider trading and market manipulation laws apply to event contracts. No charges have been filed as of April 2026. The investigation primarily targets individuals with access to material non-public information (government officials, corporate insiders), not typical retail traders.
