# Prediction market topic research and data

Choose the event topic first, then look for the observations or analysis it requires. This family covers specialist research across weather, sports, esports, crypto, economics, companies and politics.

How to choose topic research & data

## Follow the topic to its evidence

A source may provide observations, models or research rather than a trading interface. Compare the actual information offered and how it relates to the event you are studying. Topic coverage alone does not establish a data-provider role.

## Choose the useful input

-   Identify the measurement, model or analysis your question needs.
-   Inspect what the source actually supplies rather than relying on its topic label.
-   Keep specialist evidence distinct from market prices and contract wording.

A venue that lists contracts about weather or sports is not automatically a specialist research source for those topics. Use the research family to connect the evidence to the contract.
