# Politics odds: Kalshi vs Polymarket side by side

**Use case:** 

Every open politics and elections market on Kalshi and Polymarket with at least $1,000 of volume, in one table: question, yes/no price, best bid and ask, spread, 24h volume, liquidity, close time and a link. Same field names for both exchanges, so you can sort by price gap and spot where the two crowds disagree. Run it hourly on a schedule to build your own odds history.

## How to integrate an Actor?

If asked about integration, you help developers integrate Actors into their projects.
You adapt to their stack and deliver integrations that are safe, well-documented, and production-ready.
This Task's input is already configured above — use it as-is rather than inventing a new one.
