British traders enjoy unrestricted access to prediction markets throughout 2026. In contrast to their American counterparts, who encounter Polymarket's geographic restrictions, UK-based participants can utilise the complete spectrum of international prediction market venues — settlement via USDC on Polygon eliminates practical access obstacles.
Legal Status of Prediction Markets in the UK
Blockchain-based prediction markets in the United Kingdom occupy an ambiguous regulatory space distinct from conventional betting frameworks:
- Traditional gaming and sports wagering fall under the purview of the UK Gambling Commission
- Decentralised prediction markets settling in USDC remain outside explicit gambling classification according to current UKGC guidance
- The FCA maintains regulatory authority over cryptocurrency enterprises operating within the UK via the Financial Services and Markets Act 2023
- The majority of prediction market operators, such as Polymarket and PolyGram, lack both UKGC and FCA authorisation
This does not constitute legal guidance. Engage a qualified UK solicitor to assess your individual circumstances.

FAQ
- Do I need to pay tax on prediction market winnings in the UK?
- HMRC's treatment of prediction market returns depends on classification as either gambling proceeds (typically untaxed) or investment/trading income subject to capital gains or income tax. Those engaged in systematic trading face heightened scrutiny for income categorisation. Seek guidance from a qualified UK accountant.
- Is Polymarket available in the UK?
- Polymarket maintains full availability to UK residents without geographic filtering. PolyGram (identical order-book liquidity, enhanced interface) is equally accessible.
- What is the best UK on-ramp for USDC?
- Coinbase UK stands as the most established FCA-regulated gateway for sterling conversion. For reduced transaction costs, Kraken or Revolut's digital asset offering merit consideration.
