This market tracks the performance of a widely followed stock market index on a specific future date, allowing participants to speculate on whether the index will surpass certain thresholds.
All markets resolve based on the Nasdaq 100 index value at 3pm EDT on August 31, 2026. Each market has a unique threshold; if the index closes above the specified value (e.g., 27,599.99 for the first market, 27,609.99 for the second, etc.), that market resolves to 'Yes.' Markets close on August 31, 2026, and expiration occurs either when the index value is officially released or one week after the close date, whichever comes first. All markets adhere to modified source agency and underlying rules for indices as outlined in the Kalshi Rulebook.
