This market tracks the performance of a major stock market index on a specific date, allowing participants to speculate on whether the index will surpass certain thresholds by the end of trading on that day.
All markets resolve based on the end-of-day value of the Nasdaq 100 index on October 08, 2026, with each market having a unique threshold. If the index closes above the specified threshold for a given market, that market resolves to 'Yes'; otherwise, it resolves to 'No'. All markets close on October 08, 2026, and expiration occurs at the sooner of the official index value release or one week after the close date. The Exchange has standardized data sources and underlying definitions for index markets as per the Kalshi Rulebook.
