Polymarket review 2026
for UK users

Polymarket is the dominant global prediction market and the only major platform accessible to UK users without geographic restrictions. Betfair Exchange offers political betting with UK regulatory protection: but far less event variety. Kalshi and PredictIt are US-only. Polymarket gives UK traders access to global political, economic and crypto markets at ~2% fees, paid in USDC.

UK-specific ratings

How we rate Polymarket for UK users

UK political markets
5/5

Polymarket has deep markets on UK general elections, party leadership contests, by-elections and referendum probabilities. Liquidity on major UK events often exceeds Betfair Exchange political markets.

Fees vs alternatives
4.5/5

~2% taker fee compares favourably to Betfair Exchange commission (2–5%) and bookmaker overround (5–10%). Maker orders are free.

Access difficulty
2.5/5

No GBP deposit route. Requires Coinbase UK or Kraken (both FCA-registered), GBP → USDC conversion, MetaMask wallet, and Polygon network configuration. ~30–45 minutes for a new user.

Regulatory status (UK)
2/5

No FCA authorisation, no Gambling Commission licence. Grey zone under both FSMA 2000 and the Gambling Act 2005. No consumer protection, no GAMSTOP coverage.

Event coverage
5/5

Best global prediction market by volume. US politics, global elections, crypto prices, central bank decisions, economic data releases, AI milestones. Updated continuously.

GBP considerations
2/5

All settlement in USDC (USD). Every GBP → USDC conversion and back creates a CGT event. GBP/USD volatility adds a second layer of currency risk to every position.
