Polymarket turns questions about future events into markets for outcome shares. Understanding the contract matters more than following a dramatic price chart. This guide explains the basic idea, the difference between a forecast and a fact, and the questions to ask before you consider participating.
Start with a precisely defined question
A useful prediction has a subject, an outcome and a deadline. “Will an announcement happen before Friday?” is different from “Will the project eventually succeed?” Read the full question and its resolution rules before interpreting the price. A correct opinion about the wider topic can still be the wrong answer to a narrowly written contract. Keep the exact event definition beside your research notes.
Think in shares, not headlines
A binary contract gives you exposure to an outcome rather than ownership in the underlying company, candidate or team. The mechanics of a conventional resolved binary market distinguish winning shares from losing ones. Your entry cost, number of shares and applicable charges determine the economic result. Do not treat a cheap share as automatically good value; a low price can reflect a genuinely unlikely outcome.
Treat the market as one input
A displayed probability combines the opinions and incentives of people willing to trade. It is not a guarantee or a representative survey of everyone affected by the event. Ask whether the market is active, whether recent information is public, and whether the current quote is executable at your intended size. A thoughtful forecast can disagree with a market without assuming every disagreement is an opportunity.
Build a reading routine
Begin with the rules, then check the evidence and only then examine pricing. Record the date of your observations so an older forecast is not mistaken for a live assessment.

Questions & answers
Is a 70% price a certain outcome?
No. A probability expresses uncertainty. Events described as likely can fail, and unlikely events can happen.
Is Polystun the Polymarket exchange?
No. Polystun is an independent reading resource. Accounts and platform transactions are handled on Polymarket.
