What Is a Prediction Market?
Prediction markets are financial platforms where traders exchange contracts tied to the outcomes of forthcoming events. The price attached to each contract mirrors the aggregate probability assessment held by the market regarding whether that event will transpire. PolyGram operates as a UK-based prediction market platform offering exposure to a diverse range of international occurrences.
How Do Prediction Markets Work?
At their core, prediction market contracts pose a straightforward question: will Event X materialise by Date Y? Consider this illustration: "Will the Labour Party secure victory in the forthcoming UK general election?" Two distinct contracts become available:
- YES: Pays $1.00 should Labour emerge victorious
- NO: Pays $1.00 should Labour fail to win
When the YES contract trades at $0.65, this signals the market's assessment that Labour has roughly a 65% chance of winning. You might purchase YES if you believe the probability is higher, or NO if you reckon it's lower. Correct predictions generate returns; incorrect ones result in capital loss.
Prediction Markets vs Traditional Betting
- No overround: Traditional bookmakers embed a profit margin — prediction markets eliminate this. YES and NO prices combine to approximately $1.00
- You can sell before resolution: Close out your position at any moment prior to the event concluding
- Transparent: Market participants have full visibility of pricing and order book activity
- Crowd wisdom: Prices synthesise insights from vast numbers of market participants — frequently delivering superior accuracy compared to conventional polling methodologies

Are Prediction Markets Legal in the UK?
The regulatory standing of prediction markets within the United Kingdom remains ambiguous. They lack formal authorisation from the Gambling Commission yet face no explicit statutory prohibition. Operators such as PolyGram function using blockchain-based settlement mechanisms, distinguishing them from conventional gaming establishments.
How Accurate Are Prediction Markets?
Empirical evidence demonstrates that prediction markets consistently surpass specialist analysts and traditional survey methodologies in forecast accuracy. Polymarket's track record encompasses successful predictions of the 2024 US presidential election, numerous contests across European nations, and significant cryptocurrency developments—many months prior to actual occurrence.
