Key takeaway: Polymarket operates legally across most territories, though it occupies uncertain regulatory space in numerous jurisdictions. American users face access restrictions. Verify applicable gambling and financial regulations in your region before you begin trading.
Is Polymarket legal? The response hinges on your location. Because Polymarket functions as a decentralised blockchain-based system, no single regulatory authority oversees it — yet this does not exempt users from complying with their home nation's legislation.
United States — Blocked
US-based citizens and residents cannot use Polymarket. Following a 2022 CFTC enforcement action resulting in a $1.4 million penalty for offering unregistered derivatives contracts, Polymarket exited the American market and implements geographic blocking of US-originating traffic. Circumventing this restriction using VPN technology breaches Polymarket's user agreement.
United Kingdom — Grey zone
Britain's Gambling Commission has neither formally authorised nor prohibited outcome markets such as Polymarket. The platform remains freely accessible to UK residents, though users operate without explicit regulatory safeguards. Tax authorities expect all earnings to be reported in line with HMRC requirements.
Germany — Grey zone
Under the Glücksspielstaatsvertrag (GlüStV 2021), Germany's gambling framework creates legal ambiguity surrounding prediction markets — they are neither clearly permitted nor expressly forbidden. German participants can access Polymarket without impediment, though some legal uncertainty persists. See our detailed German legal guide.
Canada — Accessible
No national-level ban exists on consumer participation in prediction markets within Canada. Although provincial gambling statutes differ, Polymarket remains widely available and actively used by Canadian market participants.
Australia — Grey zone
The Interactive Gambling Act concentrates enforcement on platform operators rather than individual users. Australians can engage with Polymarket with relatively modest legal exposure, though the regulatory framework lacks full clarity.
