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.
All markets resolve based on the Nasdaq 100 index value at 10am EDT on August 17, 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 17, 2026, and expire either when the index value is first officially reported or one week after the closing date, whichever comes first. All index value determinations incorporate Exchange-modified source agency and underlying rules for indices as detailed in the Kalshi Rulebook.
