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.
The market resolves based on the Nasdaq 100 index value at 4pm EDT on September 21, 2026. Each market has a unique threshold value; if the index closes above the specified threshold (e.g., 27,400, 27,410, etc.), the market resolves to 'Yes.' All markets close on September 21, 2026, and expiration occurs at the sooner of the official index data release or one week after the close date. The Exchange has standardized the data source and underlying asset for all index markets as per the Kalshi Rulebook.
