What Is a Prediction Market?
Prediction markets are financial venues where traders exchange contracts tied to the results of forthcoming occurrences. The value assigned to each contract mirrors how the broader market assesses the likelihood of that event taking place. PolyGram operates as a prediction market accessible from the UK, offering exposure to outcomes across the globe.
How Do Prediction Markets Work?
At their core, prediction market contracts pose a straightforward query: will Event X materialise before Date Y? Consider this illustration: "Will the Labour Party secure victory in the forthcoming UK general election?" Two distinct contracts become available:
- YES: Should Labour prevail, this contract settles at $1.00
- NO: Should Labour fail to prevail, this contract settles at $1.00
When the YES contract trades at $0.65, the collective market assessment places Labour's winning odds at 65%. You may purchase YES if you believe the outcome is more probable, or NO if you reckon it's less probable. Correct predictions yield gains; incorrect ones result in losses on your investment.
Prediction Markets vs Traditional Betting
- Absence of overround: Traditional bookmakers embed a profit margin — prediction markets lack this. YES and NO prices together approximate $1.00
- Exit flexibility: You retain the ability to unwind any position prior to the event concluding
- Full visibility: Market participants access all pricing data and order book information openly
- Distributed intelligence: Contract valuations synthesise insights from numerous market participants — typically delivering superior accuracy relative to conventional surveys

Are Prediction Markets Legal in the UK?
Within the UK, prediction markets occupy an ambiguous regulatory position. The Gambling Commission has neither formally authorised nor formally prohibited them. Operators including PolyGram function through decentralised blockchain infrastructure, distinguishing their model from conventional gaming establishments.
How Accurate Are Prediction Markets?
Academic investigation repeatedly demonstrates that prediction markets surpass specialist analysts and conventional polling methodologies in forecast precision. Polymarket's track record encompasses accurate forecasting of the 2024 US presidential election, numerous contests across Europe, and pivotal cryptocurrency developments—frequently weeks or months ahead of conventional wisdom.
