This market tracks the performance of a major stock market index on a specific date and time, allowing participants to speculate on whether the index will meet or exceed certain threshold values.
All markets share the same core structure: each resolves to 'Yes' if the Nasdaq-100 index value at 1pm EDT on September 28, 2026 exceeds a specific threshold (e.g., 28,399.99, 28,409.99, etc.). Markets close on September 28, 2026, and expiration occurs at the sooner of the first official data release or one week after that date. All markets utilize modified source agency and underlying rules per the Kalshi Rulebook for indices.
