This market tracks the performance of a major stock market index on a specific date, allowing participants to speculate on whether the index will reach certain threshold values by the end of trading on that day.
All markets resolve based on the end-of-day value of the Nasdaq 100 index on August 27, 2026, at 4pm EDT. Each market has a specific threshold value; if the index closes above that threshold, the market resolves to 'Yes,' otherwise to 'No.' Markets close on August 27, 2026, and expire either when the index value is officially released or one week after the close date, whichever comes first. The Exchange has updated the data source and underlying rules for index markets as per the Kalshi Rulebook.
