Key takeaway: Polymarket operates in most regions worldwide except the United States. As a decentralised blockchain-based system, it functions without needing a single regulatory licence. Its lawfulness differs significantly across jurisdictions — ranging from outright prohibition (United States) to uncertain legal standing (United Kingdom, European Union, Australia) to full permissibility (much of Asia, Africa, Latin America).
The query "is Polymarket legal?" ranks among the most frequently asked questions about prediction markets online. Your answer hinges on your location, how your nation categorises prediction markets (whether as gambling, regulated financial products, or information exchanges), and the enforcement approach your regional authorities take towards international platforms operating outside their borders.
United States — Explicitly Blocked
United States citizens and permanent residents cannot access Polymarket. During 2022, Polymarket faced enforcement action from the CFTC (Commodity Futures Trading Commission), resulting in a $1.4 million settlement for providing event contracts without proper regulatory authorisation. The platform subsequently exited the American market and deployed geographic blocking alongside identity verification protocols.
Americans seeking lawful prediction market participation should consider Kalshi, which secured CFTC authorisation in 2020 and continues broadening its available markets.
European Union — Shifting Legal Framework
Prediction markets lack a harmonised regulatory framework across the EU. MiCA (Markets in Crypto-Assets Regulation) achieved complete implementation in 2024, imposing stricter standards on cryptocurrency trading venues. Nevertheless, MiCA does not directly regulate prediction markets as a category.
Currently, Polymarket remains usable throughout EU member states. Each nation enforces its own gambling and financial regulation independently:
- Germany: Occupies uncertain legal territory under GlüStV 2021. Not formally prohibited. Refer to our German legal guide
- France: The ANJ (national gambling regulator) has not issued specific guidance on prediction markets. Usable
- Netherlands: The KSA pursues enforcement against unregistered gambling operators. Prediction markets occupy ambiguous legal ground
- Spain: The DGOJ oversees digital gambling services. Polymarket functions without formal licensing status
United Kingdom — Available, Largely Unregulated
The UK Gambling Commission has neither authorised nor restricted Polymarket. Users in Britain can participate without legal impediment. The FCA's regulatory stance regarding blockchain-based prediction markets remains undefined. For revenue purposes, HMRC typically treats prediction market earnings as either capital appreciation or other miscellaneous gains.
Canada — Available
Canadian federal legislation contains no prohibition on individuals engaging with prediction markets. Gambling oversight at the provincial level concentrates on platform operators rather than individual participants. Canadians trade on Polymarket without legal barriers.
Australia — Uncertain Legal Status
The Interactive Gambling Act focuses on platform operators delivering services to Australian-based customers without appropriate licensing. Direct user participation in overseas prediction markets lacks explicit criminal penalties, yet regulatory clarity remains limited.
Asia & Rest of World
Polymarket enjoys broad availability throughout South and Southeast Asia, the Middle East, South America, and Africa. Mainland China enforces sweeping digital restrictions, and a small number of nations maintain comprehensive cryptocurrency prohibitions affecting access.
Tax Obligations Are Universal
Irrespective of Polymarket's legal standing in your location, earnings from prediction markets constitute taxable income across virtually all nations.
