Kalshi Markets API

Find Kalshi markets using filters including search, status, category, event ticker, and volume sorting.

How TPM stores Kalshi markets

TPM stores Kalshi in normalized tables: Event → PlatformMarket → Outcome → Snapshot. Each Kalshi event maps to a PlatformMarket row (identified by event_ticker), and each binary market within that event maps to an Outcome row (identified by market_ticker).
