Method
- Series = the text before the first hyphen of
event_ticker(same rule as State of Kalshi). - Category = the label Kalshi's public API gives that series today (fetched Oct 17, 2026), applied to every market in the series, including older markets. Labels may differ from what Kalshi showed when a market was listed.
- Contracts = the sum of the
volumefield in the markets files. It counts contracts, not dollars. - Never traded = markets with
volumeof zero. Settled = markets whoseresultis yes or no. - Counts only. No prices are used, and nothing here is a forecast, a trading rule or financial advice.
