This market tracks the performance of a major stock market index on a specific date, resolving based on whether the index closes above certain threshold values. It allows participants to speculate on the index's level at the end of a particular trading day in the future.
All markets resolve based on the end-of-day value of the Nasdaq 100 index on September 22, 2026, at 4pm EDT. Each market has a unique threshold value; if the index closes above that threshold, the market resolves to Yes, otherwise to No. Markets close on September 22, 2026, and expire either when the index value is officially released or one week after the close date, whichever comes first. The Exchange has applied specific modifications to the source agency and underlying for all index markets as per the Kalshi Rulebook.
