Prediction Markets UK
Prediction markets turn collective opinion into a live price. This hub explains how those prices work, where UK users can access them and how to interpret them without mistaking probability for certainty.
What a prediction market measures
A prediction market lets participants take positions on the outcome of a future event. A YES contract priced at 64p is commonly read as a market-implied probability of roughly 64%. The price changes as traders respond to news, new evidence and each other.
Markets can cover sport, politics, economics, technology and entertainment. Their usefulness depends on clear settlement rules, active participation and enough liquidity for prices to reflect more than one or two opinions.
The UK market
For British users, licensed betting exchanges are the established real-money route. Crypto-settled and overseas event-contract platforms may publish useful prices, but access and consumer protections differ. Always check current terms and regulatory status before depositing.

How to read the number
Market prices are estimates, not promises and not PredictionSites.co.uk forecasts. A 70% outcome can still lose three times in ten. Compare liquidity, spread, settlement wording and source platform before relying on a headline probability.
