Key takeaway: Polymarket operates in most territories beyond the United States. As a decentralised blockchain-based protocol without centralised licensing, its legal standing fluctuates considerably—ranging from outright prohibition (United States) through regulatory ambiguity (United Kingdom, European Union, Australia) to full permissibility (most Asian, African, and South American jurisdictions).
When people ask "is Polymarket legal?", they're raising the most frequently posed question in the prediction-market sector. Your answer hinges on your geographic location, how your nation's authorities categorise prediction markets (whether as gaming, tradeable instruments, or information exchanges), and the vigour with which regulators pursue enforcement against international platforms.
United States — Explicitly Blocked
Polymarket remains unavailable to American citizens and permanent residents. Following a 2022 enforcement action, the CFTC (Commodity Futures Trading Commission) imposed a $1.4 million penalty against the platform for distributing event contracts absent proper authorisation. The platform subsequently exited the American market and deployed geofencing alongside identity-verification protocols.
Americans seeking lawful prediction-market participation should consider Kalshi, which obtained CFTC authorisation in 2020 and continues broadening its contract catalogue.
European Union — Evolving Regulation
Prediction-market regulation across the EU lacks harmonisation. MiCA (Markets in Crypto-Assets Regulation) achieved full implementation during 2024 and imposes fresh compliance obligations on blockchain-based trading venues. Nevertheless, MiCA does not specifically address prediction markets.
Practically speaking, Polymarket remains usable throughout EU member states. Each nation applies distinct gambling and financial-services legislation:
- Germany: Operates within regulatory ambiguity under GlüStV 2021. No explicit prohibition. See our German legal guide
- France: The ANJ (gaming regulator) has issued no specific guidance on prediction markets. Accessible to users
- Netherlands: KSA enforcement targets unlicensed gaming operators. Prediction markets occupy uncertain legal terrain
- Spain: DGOJ oversees digital gambling activities. Polymarket technically functions but holds no licence
United Kingdom — Accessible, Unregulated
Britain's Gambling Commission has neither authorised nor prohibited Polymarket. UK-based participants can access the platform without impediment. The FCA's stance regarding blockchain-based prediction markets remains undefined. Revenue authorities (HMRC) typically treat prediction-market returns as either investment gains or other income for taxation.
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 via Polymarket without legal barriers.
Australia — Grey Zone
The Interactive Gambling Act focuses enforcement on operators delivering services into Australia without authorisation. Direct user participation in overseas prediction markets falls outside criminal liability, though legal certainty remains limited.
Asia & Rest of World
Polymarket enjoys broad accessibility throughout South-East Asia, the Gulf region, Latin America, and sub-Saharan Africa. Exceptions include mainland China (comprehensive digital restrictions) and select nations maintaining comprehensive cryptocurrency prohibitions.
Tax Obligations Are Universal
Even where Polymarket enjoys explicit legal standing, earnings from prediction markets constitute taxable income across virtually all jurisdictions.
