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.
The market resolves based on the Nasdaq 100 index value at 1pm EDT on August 17, 2026. Each market has a unique threshold; if the index closes above the specified threshold (e.g., above 27,999.99 for the first market, above 28,009.99 for the second, and so on up to above 31,989.99 for the last market), that market resolves to Yes. All markets close on August 17, 2026, and expire either when the index value is officially released or one week after the close date, whichever comes first. The rules reference modifications to data sources per the Kalshi Rulebook for index markets but do not affect the core resolution mechanism described.
