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 September 25, 2026. Each market has a unique threshold value; if the index closes above that threshold on the specified date, the market resolves to Yes. All markets close on September 25, 2026, and expiration occurs at the sooner of the official data release or one week after the close. The Exchange has standardized data sources and underlying definitions for all index-related markets as per the Kalshi Rulebook.
