A resolution source is the reference, such as an official report or news outlet, that a market uses to decide the final outcome.
Understanding resolution source helps you read prices and manage risk on any prediction market platform.
Example
A weather market might name a specific meteorological agency as its resolution source before trading opens.
Why it matters
Knowing how resolution source works lets you compare markets and avoid costly mistakes when trading.
Practical tip
Before trading, check how resolution source shows up on the specific platform you use, since interfaces and terminology can vary slightly between exchanges. Reviewing a few live markets is a quick way to see resolution source in action before risking real funds.
