This market tracks the performance of a major stock market index on a specific date and time, allowing participants to speculate on whether the index will surpass certain threshold values.
All markets resolve based on the Nasdaq 100 index value at 2pm EDT on August 31, 2026. Each market has a unique threshold value; if the index closes above that threshold, the market resolves to Yes. Markets close on August 31, 2026, and expiration occurs at the sooner of the first data release or one week after the close date. All markets follow the same secondary rules regarding closing and expiration timing, and share identical provisions about data sourcing as modified in the Kalshi Rulebook for index markets.
