Prediction Market Regulation in 2027: What to Watch

Prediction-market regulation in 2027 will be decided less by new laws than by courts and regulators applying old ones. The US fight over federal preemption, the EU's country-by-country gambling rules, the UK's licensing regime and Asia's bans are all in motion. A trader who understands the calendar can anticipate access changes before they happen.

This article maps the main jurisdictions and the events most likely to matter. It is not a prediction of outcomes. It is a list of the decisions that will determine them.

United States: the preemption question

The central issue is whether the Commodity Exchange Act preempts state gambling law for event contracts. If the answer is yes, platforms can operate nationwide under CFTC oversight. If the answer is no, they face a state-by-state patchwork.

In 2026, federal judges in Arizona and Minnesota accepted preemption, while state courts in Massachusetts, Nevada, Ohio and Washington ruled against prediction markets. The CFTC sued several states to protect its jurisdiction. The Supreme Court may eventually have to resolve the split.

The federal preemption article explains the arguments.

What to watch in 2027:

• Appellate rulings in the state cases.
• A Supreme Court cert grant.
• New state legislation, following Minnesota's ban.
• CFTC enforcement and rulemaking.
• The agency's inquiry into Polymarket's 2022 settlement.

Congress: more bills, little legislation

At least eight prediction-market bills were introduced in early 2026. They covered insider trading, sports contracts, war markets and betting by government officials. The Senate banned its own members and staff from betting on prediction markets in May 2026.

Comprehensive legislation is unlikely in the near term. The politics are divided, the Trump family has financial interests in the industry, and lawmakers disagree on whether prediction markets are derivatives or gambling. The lobbying article explains the influence campaign.

What to watch: committee hearings, a bipartisan insider-trading bill, and any legislation attached to a must-pass package.

Europe: no single licence

The EU does not have a unified prediction-market licence. Gambling is regulated nationally, and financial regulation is separate. That means a platform can be legal in one member state and blocked in the next.

France, Belgium, Switzerland, Poland, Portugal, Greece, Romania, Italy, Spain and the Netherlands have all restricted Polymarket. The European Securities and Markets Authority has discussed the regulatory gap, but it does not have authority over national gambling law.

The global bans map lists the jurisdictions.

What to watch in 2027: new national blacklists, EU-level guidance on event contracts, and court challenges to national blocks.

United Kingdom: gambling and financial rules

The UK has a strict gambling licensing regime and a separate financial conduct regime. Polymarket has been restricted for UK users. The Gambling Commission and the Financial Conduct Authority have both examined event contracts, and the treatment depends on how the product is structured.

The UK is unlikely to create a special prediction-market licence. The more likely path is enforcement against unlicensed operators and guidance for licensed bookmakers.

What to watch: FCA statements, Gambling Commission enforcement, and any change in the treatment of event contracts as derivatives.

Asia: enforcement, not liberalisation

Singapore, Thailand, South Korea, Indonesia and Australia have all restricted or blocked Polymarket. The common rationale is gambling law. Some jurisdictions also object to political markets.

There is little sign of liberalisation. The more likely trend is tighter enforcement, especially as payment providers and app stores come under pressure.

What to watch: new blocks, payment restrictions and app-store removals.

Latin America: Brazil leads

Brazil blocked Polymarket and Kalshi in April 2026 over illegal betting. Other countries in the region are watching. Mexico and Argentina have their own gambling regimes and could follow.

What to watch: Brazil's implementation, regional coordination and any licensing framework for event contracts.

The cross-border issues

Three issues cut across jurisdictions.

Insider trading. The US, Israel and other countries have charged people over prediction-market bets. Expect more enforcement and more platform surveillance.

Anti-money laundering. Crypto-settled markets face AML obligations in many jurisdictions. Identity checks and transaction monitoring are likely to increase.

Tax. The classification of event contracts varies. Some countries treat them as gambling, others as derivatives. Expect more guidance and more reporting requirements.

The tax guide explains the records to keep.

The court calendar matters more than the legislative calendar

Most of the important decisions in 2027 will come from courts, not Congress. Appeals in the state preemption cases, the CFTC's enforcement actions and private lawsuits against platforms will move faster than legislation.

A single appellate ruling can change access in a dozen states. A Supreme Court grant can freeze the issue for a year. A settlement can remove a platform from a market without a new law.

That is why traders should follow the dockets, not just the headlines. The state regulators article explains the cases.

A trader's checklist for 2027

• Check your local regulator's position every quarter.
• Read the platform's geoblock list.
• Keep funds small and withdrawals easy.
• Record every deposit, trade and withdrawal.
• Avoid markets whose legality depends on a pending court case.
• Diversify venues if you have access to more than one.

The bottom line

Regulation is not a single event. It is a series of decisions by courts, agencies and legislators. In 2027, the most important decisions will be judicial, not legislative. The platforms that survive will be the ones that can adapt to a patchwork without losing their users.
