How International Prediction Market Regulation Works

Every trader locked out asked the same question: What changed?

Nothing changed. The law was always unclear. What changed was enforcement. This is the fundamental reality of international prediction market regulation in 2026: legal status isn't fixed. What's perfectly legal in one country is explicitly prohibited fifty miles away. There is no global standard, no international treaty, no shared framework. Instead, each country applies existing gambling, securities, or derivatives law to a technology that doesn't fit cleanly into any of those categories.

The short version: Prediction market legal status by country varies dramatically. In the US, real-money platforms need approval from the Commodity Futures Trading Commission, a federal agency that oversees derivatives markets. Kalshi has this approval; Polymarket doesn't. The UK treats prediction markets as gambling, requiring licensing from the Financial Conduct Authority. Most of Europe bans unregulated platforms outright. Polymarket, which uses cryptocurrency and operates offshore, blocks US users following a 2022 settlement but runs globally elsewhere, though Polymarket regulation international has tightened significantly with country-specific bans. No two countries regulate prediction markets identically. What's legal depends on your location, the platform's registration, whether real money or crypto is involved, and whether regulators classify the contract as a security, derivative, or bet.

For broader context on prediction market mechanics, see our guide to prediction markets.

Why Prediction Markets Break Regulatory Systems

Regulators face a classification problem. Prediction markets don't fit existing legal boxes.

A contract on Federal Reserve interest rate decisions looks like a financial derivative. A product whose value derives from an underlying asset or event. Derivatives fall under securities law in most countries, requiring registration, disclosure rules, and investor protections.

A contract on Super Bowl winners looks like sports betting. Gambling law applies, with licensing requirements, age restrictions, and problem gambling protections.

A contract on whether a senator will resign? That's harder to classify. It's not tied to a financial asset. It's not pure chance. And it creates a disturbing possibility: someone holding a large position could profit by manufacturing the scandal that forces the resignation. That's not just betting. It's a financial incentive to manipulate the real-world outcome.

The Commodity Futures Trading Commission documented this risk in its October 2024 Market Surveillance Report, identifying $143 million in suspicious profits across more than 210,000 trades on Polymarket. In many cases, individuals with advance access to information (leaked government reports, early corporate announcements) traded ahead of public disclosure. The markets accurately predicted outcomes, but not because of collective wisdom. Because insiders gamed them.

So regulators ask three questions, none of which prediction markets answer cleanly:

Is this gambling? Most gambling frameworks define betting as staking money on an uncertain event determined by chance. The UK Gambling Act 2005, Australia's Interactive Gambling Act 2001, Singapore's Remote Gambling Act 2014 all use similar language. Prediction markets argue they aggregate information rather than create randomness, but regulators in 18 of 27 European Union member states default to gambling classification anyway.

Is this securities trading? If contracts have underlying economic value tied to real-world assets or outcomes, they might require the same registration and investor protection rules that apply to stocks and bonds.

Is this a derivative? In the US, the CFTC treats event contracts as derivatives. Financial instruments whose value depends on something else happening. The European Securities and Markets Authority, which coordinates financial regulation across the EU, banned binary options in 2018 because they functioned like bets on price movements. Many prediction market contracts work identically, which made the regulatory environment hostile even before specific platform bans started.

The fundamental question remains unresolved internationally. Most countries punt by treating prediction markets as unlicensed gambling and blocking access.

But that creates the next problem: enforcement. A platform incorporated in the British Virgin Islands, accepting cryptocurrency deposits, with no physical office and no fiat banking relationships. What country has jurisdiction? Where do you serve the lawsuit?

That difficulty explains why prediction markets operated in legal ambiguity for years. Not because regulators approved them. Because shutting them down was harder than ignoring them. Then trading volume hit $64 billion in 2025, dominated by bets on the US presidential election, and ignoring them stopped being an option.

Three Regulatory Models Have Emerged

Understanding where are prediction markets legal requires examining three regulatory models. Countries responded in different ways, but the approaches cluster into three patterns, each of which we detail across our step-by-step guides to navigating prediction market compliance:

Prohibition. The most common approach determining prediction market legal status by country. Countries ban prediction markets by applying existing gambling or unlicensed financial services laws. Poland (January 8, 2025), Singapore (January 12, 2025), Belgium (February 3, 2025), Bulgaria (February 2, 2026), and Portugal (March 17, 2026) all moved to restrict or ban major platforms. France, Italy, Switzerland, Romania, and Australia joined them. The default position globally is "not legal because not explicitly legal."

Licensing. The UK and Australian approach. Allow prediction markets under strict gambling licenses. The UK Gambling Commission requires operators to hold capital reserves, implement problem gambling protections, restrict certain contract types, and limit advertising. Australia classifies prediction markets as gambling requiring licensing from state-level authorities. Both systems limit what contracts can be offered and to whom. It's legal, but barely viable commercially. Smarkets, a UK-based exchange, operated under Gambling Commission licensing until pivoting to institutional trading services in 2023. The regulatory burden (capital requirements, compliance costs, advertising restrictions) made the retail business model difficult.

Experimental zones. Limited US approval. The CFTC approved Kalshi in September 2020 as the first retail prediction market platform in over thirty years. The approval process took two years, cost millions in legal fees, and resulted in tight restrictions on contract types. Kalshi can offer "event contracts" on economic indicators, weather, and awards, but not elections until a complex 2024 legal battle forced regulatory reversal. It's not a blanket approval. It's case-by-case authorization, with each new contract category requiring separate legal justification.

None of these models work well. Prohibition is the default, but crypto platforms like Polymarket operate anyway, geoblocking specific countries while remaining accessible elsewhere. Licensing is expensive and restrictive, discouraging platforms from entering those markets. Experimental approval is slow and uncertain.

What's missing is a regulatory framework designed for prediction markets rather than adapted from gambling, securities, or derivatives law. No country has built one yet.

What It Means for Traders

If You're in the US

Kalshi operates legally under CFTC approval. It's the safest option for real-money prediction market trading in the US, though state-level legal challenges continue. Nevada filed suit in January 2026 arguing Kalshi violated state gambling law. Arizona pursued criminal charges in March 2026. By April 2026, eleven states had sent cease-and-desist letters. The platform remains operational, but the legal status is contested at the state level even though federal regulators approved it.

Polymarket blocks US users. Accessing the platform via VPN violates the platform's terms of service, risking account closure and fund seizure, and potentially violates federal law under the terms of the 2022 CFTC settlement that prohibited US operations.

Offshore platforms not explicitly approved by the CFTC operate in legal gray zones. You assume legal risk and have no regulatory protections if something goes wrong.

(For state-specific details, see prediction markets legal by state.)

If You're in the UK or EU

Most international platforms are geoblocked. The evolution of Polymarket regulation international demonstrates this fragmentation. The platform blocks UK, French, German, Italian, Polish, Romanian, Swiss, Belgian, and Austrian IP addresses, totaling 11 countries as of April 2026.

Local licensed platforms exist but offer limited markets. UK Gambling Commission licenses restrict contract types and require responsible gambling implementations. The commission prohibits "socially sensitive" markets (contracts on deaths, terrorist attacks, or outcomes that traders might influence). The Financial Conduct Authority separately banned binary options to retail customers in 2019, treating them as risky financial products unsuitable for non-professionals. Many prediction market contracts function identically to those banned products.

Crypto platforms operate in gray zones depending on enforcement priorities. Belgium's Gaming Commission has actively pursued crypto gambling platforms since 2023. France's gambling regulator blocked four crypto prediction sites in 2024 alone. Other countries focus enforcement elsewhere. Legal status is ambiguous; enforcement is inconsistent.

If You're Elsewhere

Checking prediction market legal status by country before trading is essential. Platform access doesn't equal legal permission. Countries including Japan, South Korea, Thailand, and the United Arab Emirates classify online gambling or unlicensed financial services as illegal even if platforms technically allow registration.

Understand withdrawal risk. If you profit substantially and attempt to withdraw to a bank account, financial institutions may flag the transaction. Banks report suspicious activity to financial authorities. Crypto withdrawals to exchanges face similar scrutiny.

Using a platform that hasn't geoblocked you doesn't mean you're legally permitted to trade there. You bear compliance responsibility, not the platform.

Country-by-Country Breakdown

Traders asking "where are prediction markets legal?" face a complex answer that depends on platform, location, and contract type. The breakdown below details specific jurisdictions:

United States

The CFTC regulates prediction markets as "event contracts." A specific type of derivative whose value depends on whether a specified event occurs. But CFTC approval is narrow, hard-won, and doesn't override state law.

Kalshi operates under explicit CFTC approval granted in September 2020. The agency designated it a contract market, the same regulatory status granted to major derivatives exchanges like CME Group, which operates futures markets for commodities like oil and grain. Kalshi operates legally at the federal level in all 50 states as of April 2026, though state-level challenges continue.

Polymarket settled charges with the CFTC in January 2022 for operating without approval, paying a $1.4 million fine and agreeing to block US users. The ban lasted until December 2025, when the platform attempted to reopen US access under new CFTC leadership. Within eight weeks, the experiment ended amid legal pressure from multiple state attorneys general. As of April 2026, Polymarket blocks all US IP addresses.

PredictIt operated for years under CFTC No-Action Letter 14-130 (issued October 29, 2014) granted for academic research purposes through Victoria University of Wellington. The CFTC granted the exemption allowing limited real-money trading under strict position caps (capped at $850 per trader per contract) justified as data generation for political science research rather than commercial gambling revenue. The rationale: academics studying market behavior needed real stakes to observe authentic trading patterns. Play money wouldn't produce the same incentives. The letter's termination notice came in August 2022, with operations continuing under modified terms through ongoing negotiations as of April 2026.

Federal regulators classify prediction markets one way. That doesn't guarantee state acceptance. Unlike most countries, which take a single national position, the US layered federal derivatives law on top of fifty different state gambling frameworks. Banking regulations from the Financial Crimes Enforcement Network (the Treasury bureau that enforces anti-money-laundering law) add compliance burdens. The result is a regulatory maze.

Understanding how US federal classification interacts with state-level gambling law requires examining how prediction markets are regulated, which covers the CFTC's role in detail.

United Kingdom

The UK Gambling Commission regulates prediction markets under gambling law. Operating without a license is illegal. Offering contracts to UK residents requires registration, capital reserves, responsible gambling programs, and restrictions on advertising.

The regulatory burden makes most business models unviable. Smarkets, a UK-based exchange, held a Gambling Commission license but pivoted away from retail markets in 2023. The requirements (capital held in reserve, compliance staff, advertising restrictions, limits on contract types) overwhelmed revenue.

Most US platforms don't pursue UK licensing for the same reason. The UK doesn't have a prediction market industry so much as it has licensed gambling operators who occasionally offer prediction-style markets within tight limits.

European Union

The EU has no harmonized prediction market framework. Prediction market legal status by country varies across member states, and 18 of 27 prohibit unlicensed platforms.

The European Securities and Markets Authority, which coordinates financial regulation across the EU, banned binary options on July 2, 2018, treating them as speculative derivatives that harmed retail investors. Binary options are financial contracts that pay a fixed amount if a condition is met (for example, "will the euro close above $1.10 today?") and nothing otherwise. Many prediction market contracts function identically, which made the regulatory environment hostile even before specific platform bans.

Country-specific actions followed:

• France blocked Polymarket in early 2024. Its gambling regulator blocked four additional crypto prediction platforms later that year. No licensed prediction market operators exist.
• Germany treats prediction markets as unlicensed gambling under federal law.
• Italy blocked Polymarket on October 8, 2025, via the Italian Customs and Monopolies Agency. Gambling is a state monopoly; private platforms operating without licenses face immediate bans.
• Poland blocked Polymarket on January 8, 2025.
• Romania, Switzerland, Belgium, Austria all implemented bans on major platforms between 2024 and 2026.

Some EU jurisdictions (Malta, Cyprus) are crypto-friendly for blockchain companies, but prediction markets remain ambiguous. Regulatory arbitrage exists, but enforcement is tightening. No major prediction market platform operates legally across the EU under a single license. The model doesn't work under current law.

Asia-Pacific

Australia classified prediction markets as gambling and blocked Polymarket on February 6, 2026, via the Australian Communications and Media Authority. Licensed betting operators can offer some prediction-style markets under state gambling licenses, but offshore platforms face geoblocking.

Singapore banned Polymarket in January 2025 under the Remote Gambling Act, which prohibits unlicensed online betting. Despite the ban, Reuters reported in its November 6, 2024 analysis "Singapore Traders Bet Big on U.S. Election Despite Ban" that Singaporean traders placed $560 million in wagers on the 2024 US presidential election alone, a 400% increase from 2020. The surge highlights enforcement difficulty for crypto platforms. Blocking access is one thing. Preventing determined users from accessing crypto-based platforms via VPNs and offshore exchanges is another.

Japan has no explicit prediction market law, but strict gambling prohibitions apply. Operating or using unlicensed gambling platforms is illegal.

Hong Kong flagged Polymarket as potential illegal gambling. The platform is not officially approved.

Across Asia-Pacific, the default is prohibition. Singapore's experience demonstrates enforcement difficulty (trading volume surged despite the ban), but the legal position remains clear: prediction markets are unlicensed gambling and therefore illegal.

Everywhere Else

Most countries default to "not legal because not explicitly legal." If gambling requires a license and prediction markets aren't specifically carved out, they fall under gambling prohibition. Canada takes a particularly restrictive approach under the Commodity Futures Act, limiting approved prediction market contract types to just three categories: weather derivatives, certain commodity indices, and specific economic indicators. Everything else requires case-by-case regulatory approval.

Tracking Polymarket regulation international reveals enforcement difficulty for offshore platforms using crypto. Governments can order internet service providers to block domains, but VPNs and crypto transactions cross borders easily. Regulators must file cases in offshore courts (British Virgin Islands for Polymarket, Cayman Islands for others), prove jurisdiction, and enforce judgments across borders. That process takes years and often fails.

The legal position is one thing. Practical enforcement is another.

How Platforms Navigate Conflicting Rules

Platforms employ several strategies to operate across hostile jurisdictions:

Geoblocking: Polymarket uses IP address detection and, sometimes, identity verification to block users from restricted countries. Identity verification (called Know Your Customer or KYC in regulatory language) requires submitting government-issued ID, proof of address, and sometimes a selfie for facial recognition. It's the same process banks use to comply with anti-money-laundering law. After the 2022 CFTC settlement, Polymarket implemented strict US geoblocking. Following country-specific bans, it added Poland, Singapore, France, Italy, and others to the blocklist. This doesn't make usage legal for blocked users. It shifts legal liability.

Offshore incorporation: Polymarket is incorporated in the British Virgin Islands. Many platforms use Cayman Islands structures. Offshore registration doesn't make the platform legal in countries where users reside, but it complicates enforcement. Regulators must pursue cross-border legal action rather than shutting down a domestic entity. That means filing in foreign courts, proving jurisdiction, and attempting to collect fines or enforce injunctions across borders. A process that can take years and often fails.

Crypto to sidestep banking: Traditional banking requires regulatory compliance. If a platform uses regular currency, banks report transactions to financial authorities. Crypto (specifically stablecoins like USDC) bypasses traditional banking. USDC is a cryptocurrency pegged to the US dollar, meaning one USDC token equals one dollar. Users deposit dollars to buy USDC, trade using USDC on the platform, then convert USDC back to dollars when withdrawing. This doesn't make the underlying activity legal, but it removes one enforcement chokepoint. (For more on how this works, see what is USDC on Polygon.)

Play-money versions: Platforms offering play money (Manifold, Metaculus) avoid gambling classification in most jurisdictions because there's no financial stake. They're forecasting tools, not betting platforms. This model sacrifices the incentive alignment that makes real-money markets informative, but it's nearly universally legal. Exception: Some countries restrict forecasting on certain topics during campaigns. France prohibits election polling in the 48 hours before voting, which extends to play-money prediction markets.

Academic exemptions: PredictIt operated for years under a CFTC exemption granted for academic research. The rationale: limited real-money trading under strict position caps generated data for studying information aggregation, not commercial gambling revenue. Academics studying market behavior needed real stakes to observe authentic trading patterns. Play money wouldn't produce the same incentives. The exemption's status became uncertain following the 2022 termination notice, leaving the approach's future unclear.

Legal entity separation: Some platforms separate the trading mechanism from the currency or settlement layer. This creates regulatory ambiguity about which entity holds what responsibility, though it rarely provides full legal protection.

None of these strategies make platforms legal everywhere. They're navigation tactics, not solutions. The fundamental tension remains: what traders need (access, liquidity, enforceable contracts) conflicts with what regulators want (oversight, consumer protection, prevention of market manipulation). And because no international framework exists to balance those interests, platforms cobble together workarounds while traders bear ultimate compliance responsibility.

For those navigating these complexities, understanding are prediction markets gambling helps clarify why classification varies so dramatically by jurisdiction.

Common Misconceptions

"Crypto makes it legal everywhere"

No. Crypto makes enforcement harder, but it doesn't change the underlying legal status. If prediction markets are classified as unlicensed gambling in your country, using crypto instead of regular currency doesn't legalize them. France blocked Polymarket in 2024. Italy followed in October 2025. By April 2026, eleven countries had implemented IP blocks targeting the platform specifically. Not because they couldn't track crypto transactions, but because they classified the activity as illegal gambling regardless of payment method.

"If the site accepts me, it's legal"

No. Platforms make business decisions about where to geofence and where to allow access. Those decisions don't reflect legal analysis of every jurisdiction. Polymarket accepted Italian users until October 2025, when regulators forced the block. The platform made a business calculation that the Italian market wasn't worth proactive blocking until enforcement made the decision for them. You bear the legal risk, not the platform. Terms of service typically include clauses stating users are responsible for compliance with local law. That's not just liability protection for the platform. It's accurate: you're the one potentially breaking your country's law.

"Play money is always legal"

Mostly true, but not guaranteed. Play-money platforms (Manifold, Metaculus) avoid gambling classification in nearly all jurisdictions because there's no financial stake. However, France restricts election forecasting in the 48 hours before voting, and several US states prohibit election-related content during specific campaign periods. And if play money can be converted to real
