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.
All markets resolve based on the end-of-day value of the Nasdaq 100 index on September 09, 2026, at 4pm EDT. Each market has a unique threshold value; if the index closes above the specified threshold (e.g., 27,499.99, 27,509.99, etc.), the market resolves to 'Yes.' Markets close on September 09, 2026, and expiration occurs at the sooner of the official data release or one week after the close date. The Exchange has updated source agency and underlying rules for index markets as per the Kalshi Rulebook.
