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 reach certain threshold values by that moment.
All markets resolve based on the Nasdaq 100 index value at 12pm EDT on August 31, 2026. Each market has a unique threshold value; if the index closes above that threshold at the specified time, the market resolves to Yes. Markets close on August 31, 2026, and expiration occurs at the sooner of the first data release or one week after the close. All markets adhere to modified source agency and underlying rules for indices as per the Kalshi Rulebook.
