Key takeaway: Polymarket remains available across most territories outside North America. The platform functions as a decentralised blockchain-based system without centralised regulatory licensing. Jurisdictional treatment ranges from outright prohibition (United States) to permissive ambiguity (Canada, UK, Australia) to full market openness (much of Asia, Africa, Latin America).
The query "is Polymarket legal?" dominates search behaviour around prediction markets globally. Resolution hinges on your location, how your nation's authorities categorise prediction markets (whether as gambling, financial derivatives, or information exchanges), and enforcement vigour against international trading platforms.
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) through a $1.4 million penalty for operating event contracts without proper registration. The service subsequently exited the American market and deployed geofencing alongside identity-verification protocols.
American participants seeking lawful prediction market participation should consider Kalshi, which obtained CFTC authorisation in 2020 and continues broadening its contract catalogue.
European Union — Regulatory Flux
The EU lacks harmonised regulation of prediction markets. MiCA (Markets in Crypto-Assets Regulation) achieved full implementation during 2024, imposing fresh obligations on cryptocurrency trading venues. Prediction markets as a category, however, fall outside MiCA's direct scope.
Practically speaking, Polymarket functions across EU member states. National authorities enforce distinct gambling and investment regulations:
- Germany: Uncertain legal standing under GlüStV 2021. Not formally prohibited. See our German legal guide
- France: The ANJ (gambling regulator) has issued no specific guidance on prediction markets. Operational
- Netherlands: KSA pursues unlicensed gambling operators aggressively. Prediction markets occupy regulatory limbo
- Spain: DGOJ oversees internet gambling licensing. Polymarket operates without formal approval but remains accessible
United Kingdom — Accessible, Unregulated
The UK Gambling Commission has neither authorised nor prohibited Polymarket's operation. UK-based users enjoy unimpeded access. The FCA's stance on blockchain-based prediction instruments remains undefined. Revenue authorities (HMRC) typically treat prediction market returns as either investment gains or sundry earnings for taxation purposes.
Canada — Accessible
Canadian federal legislation contains no prohibition against individual participation in prediction markets. Provincial gambling frameworks concentrate enforcement on service providers rather than users. Canadian participants engage with Polymarket without legal impediment.
Australia — Grey Zone
The Interactive Gambling Act holds operators accountable for unlicensed provision to Australian residents. Direct user participation in foreign prediction markets escapes criminalisation, though the regulatory environment remains murky.
Asia & Rest of World
Polymarket operates freely throughout most of Asia-Pacific, the Gulf region, Central and South America, and sub-Saharan Africa. Exceptions include mainland China (where comprehensive digital censorship applies) and select nations maintaining comprehensive cryptocurrency prohibitions.
Tax Obligations Are Universal
