The event tracks the performance of a major stock market index on a specific date, resolving based on whether the index closes above various threshold values. Each outcome represents a different level of performance, allowing participants to assess varying degrees of market strength on that day.
All markets resolve based on the end-of-day value of the S&P 500 index on September 22, 2026, at 4pm EDT. Each market has a unique threshold, and if the index closes above that threshold (specified as "value.9999"), the market resolves to Yes; otherwise, it resolves to No. All markets close on September 22, 2026, and expire at the sooner of the first official release of the index data or one week after the close date. The Exchange has modified the Source Agency and Underlying for indices markets per the Kalshi Rulebook.
