This market tracks the performance of a major stock market index on a specific date, allowing participants to speculate on whether the index will surpass certain thresholds by the close of trading. The outcome depends entirely on the index's closing value at the specified time, with no additional conditions or events influencing the result.
All markets resolve based on the end-of-day value of the Nasdaq 100 index on October 20, 2026, at 4pm EDT. Each market has a unique threshold: if the index closes above the specified value (e.g., 27,100, 27,110, up to 31,090), it resolves to "Yes"; otherwise, it resolves to "No". Markets close on October 20, 2026, and expiration occurs at the sooner of the official index release or one week after the close. All markets follow Kalshi’s modified rules for index data sourcing and underlying definitions.
