Key takeaway: Polymarket operates across most nations outside America. As a decentralised blockchain-based protocol, it functions without a centralised regulatory licence. Jurisdictional legality ranges widely — from outright prohibition (United States) to ambiguous status (United Kingdom, European Union, Australia) to full permissibility (much of Asia, Africa, Latin America).
The enquiry "is Polymarket legal?" ranks among the most frequently posed questions regarding prediction markets globally. Your answer hinges on your location, how your nation categorises prediction markets (whether as gaming, investment products, or information exchanges), and the vigour with which your authorities pursue enforcement against international platforms.
United States — Explicitly Blocked
American citizens and permanent residents cannot access Polymarket. Following a 2022 enforcement action, Polymarket settled with the CFTC (Commodity Futures Trading Commission) for $1.4 million due to offering unregistered event derivatives. The service subsequently exited the American market and deployed geographic restrictions alongside identity-verification protocols.
Americans seeking lawful prediction market participation should consider Kalshi, which obtained CFTC authorisation in 2020 and has progressively broadened its contract catalogue.
European Union — Evolving Regulation
The European Union lacks a harmonised regulatory framework for prediction markets. MiCA (Markets in Crypto-Assets Regulation) achieved complete implementation in 2024 and imposes fresh obligations on crypto trading venues. Prediction markets themselves, however, remain outside MiCA's explicit scope.
Practically speaking, Polymarket remains usable across EU member territories. Each state enforces distinct gambling and investment regulations:
- Germany: Occupies uncertain legal territory under GlüStV 2021. Not formally prohibited. Consult our German legal guide
- France: The ANJ (gambling regulator) has issued no specific ruling on prediction markets. Broadly available
- Netherlands: The KSA pursues unlicensed gaming operators aggressively. Prediction markets occupy unclear ground
- Spain: The DGOJ oversees internet gambling activities. Polymarket remains technically usable despite lacking authorisation
United Kingdom — Accessible, Unregulated
Britain's Gambling Commission has neither authorised nor prohibited Polymarket. UK residents enjoy unrestricted platform access. The FCA's stance regarding blockchain-based prediction instruments remains undefined. For fiscal reporting, HMRC generally treats prediction market earnings as either investment gains or other income.
Canada — Accessible
Canada's national legislation contains no prohibition against consumer participation in prediction markets. Provincial gaming statutes concentrate on service providers rather than participants. Canadian users engage with Polymarket unimpeded.
Australia — Grey Zone
The Interactive Gambling Act focuses on operators delivering unlicensed offerings to Australian audiences. Direct user involvement in international prediction platforms remains legally ambiguous rather than explicitly prosecuted.
Asia & Rest of World
Polymarket enjoys broad availability throughout South and Southeast Asia, the Gulf region, Latin America, and the African continent. Exceptions include mainland China (comprehensive digital restrictions) and select nations maintaining absolute cryptocurrency prohibitions.
Tax Obligations Are Universal
Even where Polymarket enjoys explicit legal standing, earnings from prediction markets constitute reportable income across virtually all tax jurisdictions.
