This market tracks the performance of a major stock market index at a specific future date and time, allowing participants to speculate on whether the index will surpass certain threshold values.
Each market resolves to 'Yes' if the Nasdaq 100 index value at 11am EDT on October 19, 2026 exceeds a specific threshold, ranging incrementally from approximately 27,900 to over 31,800. All markets close on October 19, 2026, and expire either when the index value is first officially released or one week after the close date, whichever occurs sooner. The rules specify that the Exchange has adjusted the source agency and underlying for index markets per the Kalshi Rulebook.
