What is a prediction market?
Short answer: a prediction market is a market built around a verifiable future event. A Yes price of 0.63 is commonly read as an estimated market probability of about 63%, not a guarantee.
How prediction markets work
- A question defines its deadline, outcomes and resolution source.
- Participants express Yes or No views using available information.
- Prices change with information and trading, producing a live probability signal.
- After closing, the event is resolved under its stated rules and reliable evidence.
Probability is not certainty
A 63% estimate still leaves roughly 37% for the opposite outcome. Liquidity, spreads, participation and breaking news can affect price, so always read the rules, source and update time.
