What Is a Prediction Market?
Prediction markets are venues where traders exchange contracts tied to the results of forthcoming occurrences. The value assigned to each contract mirrors what the broader market believes is the likelihood of that event taking place. PolyGram offers UK-based participants access to prediction markets spanning worldwide developments.
How Do Prediction Markets Work?
At their core, prediction market contracts pose a straightforward query: will Event X materialise before Date Y? Consider this scenario: "Will the Labour Party secure victory in the forthcoming UK general election?" Two distinct contracts become available:
- YES: Should Labour prevail, this contract yields $1.00
- NO: Should Labour fall short, this contract yields $1.00
When YES is trading at $0.65, participants interpret this as indicating roughly 65% odds that Labour will succeed. You might purchase YES if you believe the outcome more probable, or acquire NO if you reckon it less probable. Success in your prediction generates returns; an incorrect forecast results in forfeited capital.
Prediction Markets vs Traditional Betting
- Absence of overround: Conventional bookmakers embed a profit margin — prediction markets operate without this. YES and NO prices aggregate to approximately $1.00
- Early exit available: You may unwind your position whenever you wish, prior to the final determination
- Full visibility: Market participants enjoy unrestricted access to pricing information and order book details
- Distributed intelligence: Prices synthesise insights from a vast network of market participants — typically delivering superior accuracy relative to conventional surveys

Are Prediction Markets Legal in the UK?
The regulatory standing of prediction markets within the United Kingdom occupies uncertain terrain. They lack formal authorisation from the Gambling Commission yet face no explicit statutory prohibition. Organisations like PolyGram function through decentralised blockchain infrastructure, distinguishing their model from conventional gambling frameworks.
How Accurate Are Prediction Markets?
Empirical evidence demonstrates that prediction markets consistently surpass professional analysts and conventional polling methodologies in forecasting precision. Polymarket's track record encompasses successful predictions of the 2024 US election outcome, numerous contests across European nations, and pivotal cryptocurrency sector developments—many anticipated substantially in advance.
