Key takeaway: Polymarket remains accessible across most regions worldwide except the United States. As a decentralised blockchain-based protocol operating without centralised licensing, its legal standing shifts considerably by territory — completely prohibited in America, occupying uncertain terrain in the UK, EU, and Australia, and largely unregulated throughout Asia, Africa, and South America.
The question "is Polymarket legal?" ranks among the most frequently asked topics within prediction market communities. Your answer hinges on your geographic location, how your nation's authorities classify prediction markets (whether as gambling, investment products, or information exchanges), and the vigour with which local enforcement agencies pursue users of international platforms.
United States — Explicitly Blocked
Polymarket remains unavailable to anyone residing in or holding citizenship of the United States. Following a 2022 enforcement action, Polymarket faced a $1.4 million penalty from the CFTC (Commodity Futures Trading Commission) over the provision of event contracts lacking proper registration. 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
EU member nations lack harmonised rules governing prediction markets. MiCA (Markets in Crypto-Assets Regulation), fully operational since 2024, imposes fresh compliance obligations on cryptocurrency trading venues. Prediction markets themselves, however, fall outside MiCA's direct scope.
Practically speaking, Polymarket operates openly across EU territory. Each country applies distinct gambling and financial regulation frameworks:
- Germany: Occupies 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. Broadly accessible
- Netherlands: The KSA pursues unlicensed gaming operators aggressively. Prediction markets occupy ambiguous terrain
- Spain: DGOJ oversees online gaming licensing. Polymarket functions without formal approval but remains reachable
United Kingdom — Accessible, Unregulated
Polymarket has neither received licensing nor faced prohibition from the UK Gambling Commission. Residents freely access the platform without legal impediment. The FCA's perspective on blockchain-based prediction markets continues to lack clarity. For taxation, HMRC ordinarily treats prediction market returns as either capital gains or miscellaneous earnings.
Canada — Accessible
Canadian federal legislation contains no prohibition against individuals engaging with prediction markets. Provincial gambling frameworks concentrate enforcement on service providers rather than participants. Canadians trade on Polymarket with no legal barriers.
Australia — Grey Zone
The Interactive Gambling Act targets businesses supplying unlicensed services to Australian residents. Direct user participation in international prediction markets escapes explicit criminalisation, though regulatory clarity remains limited.
Asia & Rest of World
Polymarket enjoys broad availability throughout South and Southeast Asia, the Middle East, Latin America, and sub-Saharan Africa. Exceptions emerge in mainland China (comprehensive digital restrictions) and select nations maintaining comprehensive cryptocurrency prohibitions.
Tax Obligations Are Universal
Even where Polymarket operates in legal grey zones, prediction market earnings constitute taxable revenue in virtually all jurisdictions. PolyGram furnishes comprehensive transaction records with FIFO cost-basis calculations to streamline tax compliance. Always engage a qualified tax professional in your region.
