Prediction markets
vs sports betting in the UK
Prediction markets (Polymarket) and sports betting (Betfair Exchange, bet365, Paddy Power) are fundamentally different instruments. For UK traders, the key question is: Betfair Exchange's political markets are the closest licensed alternative to Polymarket. This guide maps the differences.

Why Betfair Exchange is the closest UK alternative
Betfair Exchange is uniquely relevant to UK prediction market users because it operates as a peer-to-peer exchange (not a bookmaker setting prices) and covers political markets: UK general elections, party leadership, by-elections, referenda. Its 2–5% commission is competitive. It holds a full Gambling Commission licence, meaning GAMSTOP self-exclusion, deposit limits, and dispute resolution apply.
