What Is a Prediction Market?
Prediction markets are venues where traders exchange contracts whose value hinges on whether specific future occurrences come to pass. The prevailing contract price embodies the aggregate market view regarding the likelihood of that event materialising. PolyGram operates as a UK-based prediction market platform offering exposure to international developments.
How Do Prediction Markets Work?
At their core, prediction market contracts pose a straightforward proposition: will Event X materialise before Date Y? Consider this illustration: "Will the Conservative Party secure victory in the forthcoming UK general election?" Two distinct contracts exist for trading:
- YES: Holders receive $1.00 should the Conservative Party prevail
- NO: Holders receive $1.00 should the Conservative Party fail to prevail
Suppose YES trades at $0.65 — this signals the market assigns a 65% chance to Conservative victory. You might purchase YES if you believe the odds understate their prospects, or acquire NO if you reckon they overstate them. Accurate predictions yield gains; incorrect ones result in losses on your investment.
Prediction Markets vs Traditional Betting
- Absence of built-in margin: Traditional bookmakers embed a profit margin into odds — prediction markets sidestep this. YES and NO prices aggregate to approximately $1.00
- Early exit capability: Liquidate your holdings at any point prior to final settlement
- Full visibility: Market participants enjoy unrestricted access to pricing data and order-book information
- Distributed intelligence: Prices synthesise insights from a broad participant base — frequently surpassing traditional polling in precision

Are Prediction Markets Legal in the UK?
Prediction markets occupy ambiguous regulatory territory within the United Kingdom. The Gambling Commission has neither granted formal authorisation nor issued explicit prohibitions. Operators including PolyGram function via distributed ledger settlement mechanisms, distinguishing them from conventional gaming establishments.
How Accurate Are Prediction Markets?
Empirical studies demonstrate that prediction markets consistently outperform specialist analysts and conventional survey methodologies. Polymarket's track record encompasses accurate forecasting of the 2024 US presidential election, various contests across Europe, and significant cryptocurrency developments — frequently months in advance of occurrence.
