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 surpass certain threshold values.
The market resolves based on the Nasdaq 100 index value at 3pm EDT on October 19, 2026. Each market has a unique threshold; if the index closes above the specified threshold (e.g., 27,899.99, 27,909.99, etc.), that market resolves to 'Yes.' All markets close on October 19, 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 indices markets but do not alter the core resolution mechanism described above.
