Key takeaway: Polymarket operates across most nations outside North America. The platform functions as a decentralised blockchain-based protocol without centralised licensing in any single jurisdiction. Regulatory treatment spans a spectrum — from outright prohibition (United States) through ambiguous territory (Canada, UK, EU member states, Australia) to fully permissive frameworks (most Asian, African, and South American jurisdictions).
The inquiry "is Polymarket legal?" ranks among the most frequently posed questions in the prediction-market space. Your answer hinges on your geographic location, how your nation's authorities classify event contracts (whether as gaming, securities, or information instruments), and the vigour with which regulators pursue enforcement against international platforms.
United States — Explicitly Blocked
US persons and permanent residents cannot access Polymarket. Following a 2022 enforcement action, the platform remitted $1.4 million to the CFTC (Commodity Futures Trading Commission) after offering derivatives without proper registration. The service subsequently exited the American market and deployed geographic filtering plus identity-verification protocols.
American traders seeking lawful event-contract access 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 on event contracts. MiCA (Markets in Crypto-Assets Regulation) achieved full implementation in 2024 and imposes fresh compliance obligations on blockchain-based trading venues. Event contracts themselves, however, fall outside MiCA's direct scope.
Practically speaking, Polymarket remains accessible throughout EU territory. Member states enforce divergent gambling and investment regulations:
- Germany: Uncertain legal standing under GlüStV 2021. Not formally prohibited. See our German legal guide
- France: The ANJ (national gaming regulator) has issued no specific ruling on event contracts. Available to users
- Netherlands: KSA enforces strict licensing for gaming operators. Event contracts occupy murky regulatory terrain
- Spain: DGOJ oversees iGaming licensing. Polymarket exists in a legal grey zone for unlicensed operators
United Kingdom — Accessible, Unregulated
The UK's Gambling Commission has neither authorised nor prohibited Polymarket. UK residents freely utilise the platform. The FCA has not articulated a definitive stance on blockchain-based event contracts. Revenue authorities (HMRC) typically treat event-contract earnings as either investment gains or sundry income for tax purposes.
Canada — Accessible
Canadian federal legislation contains no prohibition against individual participation in event contracts. Provincial gaming 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 furnishing services to Australian residents without authorisation. Direct participation by individuals in offshore event-contract platforms avoids criminal liability, though the regulatory environment remains unsettled.
Asia & Rest of World
Event contracts are broadly available in Southeast Asian markets, the Gulf region, Latin America, and Sub-Saharan Africa. Exceptions include mainland China (pervasive digital censorship) and a small number of nations maintaining comprehensive cryptocurrency prohibitions.
Tax Obligations Are Universal
Irrespective of Polymarket's legal standing in your territory, earnings from event contracts constitute taxable income in nearly all jurisdictions. PolyGram furnishes comprehensive transaction records and FIFO cost-basis calculations for compliance reporting. Engage a qualified tax professional in your region.
