This market tracks the performance of a major stock market index on a specific date, allowing participants to speculate on whether the index will meet or exceed certain threshold values by the end of trading on that day.
All markets resolve based on the official closing value of the Nasdaq-100 index on September 08, 2026 at 4pm EDT. Each market has a distinct threshold value; if the index closes at or above the specified threshold, the market resolves to Yes, otherwise to No. Markets close on the event date and expire either when the index value is officially released or one week after the close, whichever comes first. All index values are sourced and calculated according to modifications outlined in the Kalshi Rulebook for indices markets.
