This market tracks the performance of a major stock market index on a specific future date, allowing participants to speculate on whether the index will surpass certain threshold values by that time.
The market resolves based on the end-of-day value of the Nasdaq 100 index on October 29, 2026. Each market has a specific threshold value; if the index closes above that threshold, the market resolves to Yes, otherwise to No. All markets close on October 29, 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.
