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 meet or exceed certain threshold values.
All markets resolve based on the Nasdaq 100 index value at 2pm 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 published or one week after the close date, whichever comes first. All index value determinations incorporate Exchange-modified source agency and underlying rules as specified in the Kalshi Rulebook.
