What Is a Prediction Market?
Prediction markets represent financial venues where traders exchange contracts contingent upon 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 operates as a UK-based prediction market platform offering exposure to worldwide developments.
How Do Prediction Markets Work?
Every prediction market contract centres on a straightforward proposition: does 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, participants interpret this as a 65% chance of Labour winning. You might purchase YES if you believe the outcome is more probable, or acquire 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 eliminate this. YES and NO prices combine to approximately $1.00
- Exit flexibility: You may liquidate your holding at any moment before the event concludes
- Full visibility: Pricing information and order book details remain openly accessible
- Distributed intelligence: Market prices consolidate insights from numerous market participants — frequently surpassing accuracy of conventional surveys

Are Prediction Markets Legal in the UK?
Prediction markets occupy an ambiguous legal position within British jurisdiction. The Gambling Commission has neither granted formal authorisation nor issued explicit prohibitions. Operators such as PolyGram function through distributed ledger settlement mechanisms, distinguishing them from conventional gaming activities.
How Accurate Are Prediction Markets?
Empirical investigation demonstrates that prediction markets regularly surpass specialist analysts and statistical polling in forecast precision. Polymarket's assessments proved correct regarding the 2024 US presidential election, numerous contests across Europe, and significant cryptocurrency developments—often weeks or months in advance of actual outcomes.
