Key takeaway: Polymarket remains available across most territories outside the United States. The platform functions as a decentralised blockchain-based system without centralised licensing in any single jurisdiction. Regulatory treatment differs substantially by region — ranging from outright prohibition (United States) to ambiguous legal standing (United Kingdom, European Union, Australia) to full accessibility (majority of Asian, African, and South American markets).
The query "is Polymarket legal?" ranks among the most frequently posed questions about prediction markets globally. Your answer hinges on three factors: your country of residence, how your nation's authorities classify prediction markets (whether as gambling, regulated financial products, or information exchanges), and the vigour with which your regulator pursues enforcement against international platforms operating beyond their borders.
United States — Explicitly Blocked
Polymarket does not operate for United States citizens or permanent residents. Following a 2022 enforcement action, Polymarket settled a $1.4 million penalty with the CFTC (Commodity Futures Trading Commission) after offering event contracts in breach of registration requirements. 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
The European Union maintains no harmonised regulatory framework for prediction markets. MiCA (Markets in Crypto-Assets Regulation), which achieved full implementation in 2024, imposes fresh compliance obligations on cryptocurrency trading venues. Notably, prediction markets themselves fall outside MiCA's express scope.
Practically speaking, Polymarket remains accessible throughout EU member states. Each country enforces distinct gambling and financial conduct statutes:
- Germany: Sits in grey-zone territory under GlüStV 2021. Not formally prohibited. See our German legal guide
- France: ANJ (the gambling regulator) has issued no specific ruling on prediction markets. The platform functions without obstruction
- Netherlands: KSA pursues unlicensed gambling operators aggressively. Prediction market classification remains uncertain
- Spain: DGOJ supervises internet gambling activity. Polymarket operates without a formal licence but remains accessible
United Kingdom — Accessible, Unregulated
The UK Gambling Commission has neither authorised nor prohibited Polymarket. UK-based users engage with the platform without legal impediment. The FCA's stance on cryptocurrency-based prediction markets has not crystallised. Revenue authorities (HMRC) typically treat prediction market earnings as either capital gains or miscellaneous income for tax purposes.
Canada — Accessible
Canadian federal legislation contains no prohibition against individual participation in prediction markets. Provincial gambling rules concentrate on platform operators rather than end-users. Canadian participants access Polymarket without legal barriers.
Australia — Grey Zone
Australia's Interactive Gambling Act focuses enforcement on operators delivering unlicensed services to Australian residents. Direct user participation in offshore prediction markets escapes explicit criminalisation, though the regulatory environment remains unsettled.
Asia & Rest of World
Polymarket enjoys broad accessibility throughout Southeast Asia, the Middle East, Central America, and the African continent. Exceptions include mainland China (due to comprehensive internet controls) and select nations maintaining absolute cryptocurrency prohibitions.
Tax Obligations Are Universal
Even where Polymarket operates in a legal grey area, earnings from prediction markets constitute taxable income across virtually all jurisdictions.
