Series ticker

Kalshi's identifier for a recurring family of markets — e.g. one series for monthly CPI releases. Series contain events (each release), which contain markets (each strike). Filtering the API by series ticker is the efficient path to recurring data.

Kalshi organizes its catalog in three tiers, each with a ticker: the series (the recurring question), the event (one occurrence), and the market (one tradable binary within it). The series ticker is the stable root — event and market tickers are typically derived from it with date and strike suffixes.

Worked example

A monthly economic-data series keeps one series ticker forever; each month's release is a new event under it, and each threshold ("above 3.0%", "above 3.2%") is a market under that event. A bot trading every CPI print doesn't search by keyword each month — it lists events under the known series ticker and picks up the new ones automatically. (Exact ticker formats are documented by Kalshi and worth verifying; they've evolved over time.)

Why it matters for cross-venue work

Polymarket has no direct equivalent — related markets group under events and tags rather than a formal series hierarchy — so recurring-market mapping between venues has to be built (or bought: it's part of what a unified market ID abstracts). API usage patterns are in the Kalshi API guide.
