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 meet or exceed certain threshold values.
The market resolves based on the Nasdaq 100 index value at 1pm EDT on October 26, 2026. Each market has a unique threshold value; if the index closes above the specified threshold (e.g., 26,900 or above), that market resolves to 'Yes.' All markets close on October 26, 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.
