Key takeaway: Polymarket operates legally across most territories, though regulatory clarity remains elusive in numerous jurisdictions. American users face outright prohibition. Review applicable gambling and financial regulations in your region before engaging.
Is Polymarket legal? The response hinges on your geographical location. Polymarket functions as a decentralised blockchain protocol without a single regulatory authority — yet this structure does not exempt users from compliance with national legislation.
United States — Blocked
US citizens and residents cannot use Polymarket. Following a $1.4 million CFTC settlement in 2022 over the provision of unregistered event derivatives, Polymarket exited the American market and enforces geoblocking against US-based internet connections. Circumventing this restriction through VPN technology breaches Polymarket's user agreement.
United Kingdom — Grey zone
The UK Gambling Commission has neither formally authorised nor prohibited prediction market platforms such as Polymarket. The platform remains accessible to British users, though they operate outside formal regulatory safeguards. Income generated through trading must be reported to HMRC in accordance with applicable tax legislation.
Germany — Grey zone
Germany's Glücksspielstaatsvertrag (GlüStV 2021) establishes the framework for online gaming regulation. Prediction markets occupy an uncertain position within this legal structure — neither expressly sanctioned nor explicitly prohibited. German participants can access Polymarket without impediment, though some legal uncertainty persists. Our comprehensive German legal guide explores this further.
Canada — Accessible
No national-level restriction prevents Canadian consumers from participating in prediction markets. Gambling frameworks differ across provinces, yet Polymarket remains openly available and widely utilised by Canadian market participants.
Australia — Grey zone
The Interactive Gambling Act in Australia concentrates its enforcement on platform operators rather than individual participants. Australian traders can engage with Polymarket with relatively modest legal exposure, although the regulatory environment retains some ambiguity.
