Key takeaway: Polymarket remains available across most territories outside the United States. As a decentralised blockchain-based protocol, it operates without a centralised regulatory licence. Jurisdictional treatment spans a spectrum: outright prohibition (United States), uncertain legal standing (United Kingdom, European Union, Australia) to full permissibility (majority of Asia, Africa, South America).
The question "is Polymarket legal?" ranks amongst the most frequently posed inquiries regarding prediction markets globally. Your answer hinges on your geographic location, how your nation categorises prediction markets within its legal framework (whether as gambling, financial products, or information services), and the enforcement vigour your regulator applies to international platforms operating offshore.
United States — Explicitly Blocked
US citizens and permanent residents cannot access Polymarket. Following a 2022 enforcement action, Polymarket settled with the CFTC (Commodity Futures Trading Commission) for $1.4 million due to offering event contracts without proper registration. The platform subsequently exited the American market and deployed geofencing alongside identity verification protocols.
Americans seeking lawful prediction market participation should consider Kalshi, which secured CFTC authorisation in 2020 and continues broadening its contract catalogue.
European Union — Evolving Regulation
EU member states lack harmonised rules governing prediction markets. MiCA (Markets in Crypto-Assets Regulation) achieved full implementation in 2024, imposing fresh compliance obligations on crypto trading venues. Nonetheless, prediction markets as a category fall outside MiCA's direct scope.
On the ground, Polymarket functions across EU territories. Each member state applies distinct gambling and financial conduct statutes:
- Germany: Ambiguous standing under GlüStV 2021. No outright prohibition. Consult our German legal guide
- France: The ANJ (gambling regulator) has issued no specific ruling on prediction markets. Accessible to users
- Netherlands: The KSA pursues unlicensed gambling operators aggressively. Prediction markets occupy uncertain legal terrain
- Spain: DGOJ oversees online gambling licensing. Polymarket functions but lacks formal authorisation
United Kingdom — Accessible, Unregulated
Britain's Gambling Commission has neither authorised nor prohibited Polymarket. UK residents freely use the service. The FCA's stance toward crypto-based prediction venues remains undefined. Regarding tax treatment, HMRC typically characterises prediction market returns as either capital appreciation or miscellaneous revenue.
Canada — Accessible
Canadian federal legislation contains no prohibition on individual participation in prediction markets. Provincial gambling rules concentrate on platform operators rather than end-users. Canadian participants engage with Polymarket without legal impediment.
Australia — Grey Zone
The Interactive Gambling Act focuses enforcement on operators supplying unlicensed services into Australia. Direct user participation in overseas prediction platforms remains legally ambiguous, though not explicitly prosecuted.
Asia & Rest of World
Polymarket operates openly across South-East Asia, the Gulf region, South America, and sub-Saharan Africa. Exceptions include mainland China (comprehensive digital controls) and a small number of nations maintaining blanket cryptocurrency prohibitions.
Tax Obligations Are Universal
Irrespective of local legal status, earnings from prediction markets constitute taxable revenue in virtually all jurisdictions.
