Introduction
Caliber is an institutional-grade rating system for prediction market definitions. Learn how to evaluate market clarity, resolvability, and source quality.
What is Caliber?
Caliber analyzes prediction market definitions and assigns ratings from Aaa to C based on multiple criteria. The system evaluates how well-defined a market is, whether it can be objectively resolved, and the quality of data sources specified.
Markets with clear prompts, reliable sources, and unambiguous resolution criteria receive higher ratings. This helps market creators improve their definitions and helps participants assess market quality before trading.
Why Use Caliber?
Prediction Market Venues can use Caliber in two key ways:
- >Before market creation: Help users or agents create more robust market definitions by providing real-time feedback on quality
- >After market creation: Assess the quality of existing markets to inform trading decisions or identify problematic definitions
