Key takeaway: Polymarket remains available across most territories except the United States. As a decentralised blockchain-based protocol, it operates without a centralised regulatory licence. Jurisdictional legality spans a spectrum — from outright prohibition (United States) through regulatory ambiguity (UK, EU, Australia) to full permissibility (most Asian, African, and South American regions).
The query "is Polymarket legal?" ranks among the most frequently asked questions in the prediction-market space. Your answer hinges on your location, how your nation's authorities classify prediction markets (whether as gaming, financial products, or information exchanges), and the vigour with which local enforcement targets international platforms.
United States — Explicitly Blocked
Polymarket remains unavailable to persons residing in or holding citizenship of the United States. Following a 2022 enforcement action, Polymarket settled with the CFTC (Commodity Futures Trading Commission) for $1.4 million, having operated event contracts without proper registration. The platform subsequently exited the American market, deploying geographic restrictions and identity-verification protocols.
Americans seeking lawful prediction-market participation may turn to Kalshi, which secured CFTC authorisation in 2020 and continues broadening its contract portfolio.
European Union — Evolving Regulation
The European Union lacks a harmonised regulatory framework for prediction markets. MiCA (Markets in Crypto-Assets Regulation) achieved full implementation during 2024, imposing fresh compliance obligations on crypto trading venues. Prediction markets themselves, however, fall outside MiCA's explicit scope.
On the ground, Polymarket functions across all EU member states. Each nation applies distinct gambling and financial-services frameworks:
- Germany: Occupies grey-zone status under GlüStV 2021. Not formally prohibited. Refer to our German legal guide
- France: The ANJ (national gambling regulator) has issued no specific ruling on prediction markets. Broadly accessible
- Netherlands: The KSA vigorously pursues unlicensed gaming operators. Prediction markets occupy uncertain legal ground
- Spain: The DGOJ oversees internet gambling. Polymarket functions without formal licensing
United Kingdom — Accessible, Unregulated
The UK's Gambling Commission has neither authorised nor prohibited Polymarket. Residents of the United Kingdom engage with the platform without legal impediment. The FCA's stance on crypto-based prediction instruments remains opaque. For taxation, HMRC ordinarily treats prediction-market earnings as either capital gains or other income.
Canada — Accessible
Canadian federal legislation contains no prohibition against individual participation in prediction markets. Provincial gaming rules concentrate on platform operators rather than end-users. Canadian participants trade on Polymarket unobstructed.
Australia — Grey Zone
Australia's Interactive Gambling Act focuses enforcement on operators delivering services to Australian-resident consumers lacking appropriate licensing. Direct user participation in foreign prediction platforms remains legally uncriminalised, though the regulatory environment carries considerable uncertainty.
Asia & Rest of World
Polymarket enjoys widespread availability throughout South-East Asia, the Middle East, South America, and Africa. Exceptions include mainland China (where internet restrictions apply broadly) and select nations maintaining comprehensive cryptocurrency prohibitions.
Tax Obligations Are Universal
