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 3pm EDT on August 10, 2026. Each market has a unique threshold; if the index closes above the specified threshold (e.g., 27,299.99, 27,309.99, etc.), that market resolves to 'Yes.' All markets close on August 10, 2026, and expiration occurs at the sooner of the official index data release or one week after the close. The Exchange has updated source agency and underlying rules for index markets per the Kalshi Rulebook.
