Core ideas
What to understand before trading
A market price is not just a quote. It is the crowd’s current estimate, compressed into a tradable number.
Polls, court rulings, economic data, injuries, weather updates, and breaking news can move markets in minutes.
The exact wording of a market determines what counts as a win. Good traders read the rules before the chart.
Quick answers
Common reader questions
Are prediction markets the same as betting?
They overlap in mechanics, but the strongest use case is information discovery: prices can reveal how informed participants estimate uncertain events.
Why do prices move before mainstream coverage?
Markets react when participants update their expectations. Sometimes that happens before the story becomes obvious in headlines.
