What Is a Prediction Market?
Prediction markets function as financial venues where traders exchange contracts whose value hinges on whether specific future occurrences materialise. Market prices for these contracts embody the aggregate probabilistic assessment held by all active participants regarding the likelihood of any given event. PolyGram operates as a UK-based prediction market platform offering exposure to international event outcomes.
How Do Prediction Markets Work?
Each contract within a prediction market poses a straightforward proposition: shall Event X materialise prior to Date Y? Consider this illustration: "Will the Labour Party secure victory in the forthcoming UK general election?" Two distinct contract varieties exist:
- YES: Should Labour prevail, the contract settles at $1.00
- NO: Should Labour fail to prevail, the contract settles at $1.00
When the YES contract trades at $0.65, market participants collectively assess a 65% chance of Labour's electoral success. Traders may acquire YES contracts if they anticipate higher probability, or NO contracts if they anticipate lower probability. Correct predictions generate gains; incorrect predictions result in capital loss.
Prediction Markets vs Traditional Betting
- Absence of overround: Conventional bookmakers embed a profit margin into odds — prediction markets eliminate this spread. YES and NO contract prices aggregate to approximately $1.00
- Early exit capability: Traders may liquidate positions at any point prior to final settlement
- Full transparency: Market participants access complete pricing information and order book visibility
- Distributed intelligence: Pricing mechanisms synthesise insights from numerous independent traders — frequently surpassing accuracy of conventional polling methodologies

Are Prediction Markets Legal in the UK?
The regulatory status of prediction markets within the United Kingdom occupies an ambiguous position. Neither explicit authorisation from the Gambling Commission nor categorical prohibition currently exists. Blockchain-based platforms such as PolyGram operate under settlement mechanisms distinct from conventional gaming frameworks, creating operational distinctions that affect their legal characterisation.
How Accurate Are Prediction Markets?
Empirical evidence demonstrates that prediction markets consistently deliver superior forecasting performance relative to institutional analysts and statistical polling. Polymarket's track record encompasses accurate projections for the 2024 US presidential election, numerous continental European electoral contests, and significant cryptocurrency sector developments, frequently materialising months in advance of public consensus.
