Prediction markets
Polymarket lets users trade positions tied to outcomes of real-world events, with prices representing the market's implied probability.
A winning position can settle at a fixed value while an incorrect position can expire worthless, creating a simple but risky payoff structure.
Shares are commonly priced between zero and one unit of settlement value, so a price near one can imply that traders see an outcome as more likely. That price is shaped by available liquidity and trading incentives, and should not be interpreted as an objective probability.
How markets work
Creators define an event and outcomes, while participants provide liquidity and buy or sell shares as information changes.
The price is not a guaranteed forecast; it reflects the current balance of money, information and incentives among participants.
Participants may trade against a pool or one another, and market depth affects how much a trade moves the price. News can shift expectations quickly, while thin liquidity may make displayed odds hard to realize for larger orders.
History and regulation
Blockchain settlement can make markets transparent and globally accessible, but it also raises questions about jurisdiction and permitted wagering.
Polymarket's history shows how product growth can coexist with regulatory scrutiny and restrictions on who may trade.
Prediction-market rules differ across countries and can depend on event types, user location and product structure. Platform restrictions may change in response to legal requirements, so users should check current eligibility and avoid assuming global availability.
Evaluating a market
Users should review resolution rules, oracle design, liquidity, fees and the deadline before taking a position.
A clear event definition is as important as the market price because ambiguous settlement criteria can create disputes.
Resolution criteria explain what evidence determines the final result and when trading ends. Users should consider how disputes are handled, how the oracle reports outcomes and whether enough liquidity exists to exit before settlement.
