This set of markets 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 market represents a different threshold, allowing participants to speculate on the exact level of market performance at the close of trading on that day.
All markets resolve based on the end-of-day value of the S&P 500 index on October 27, 2026, at 4pm EDT. For each market, if the index closes above the specified threshold (e.g., 7,450.0000, 7,455.0000, etc.), the market resolves to 'Yes'; otherwise, it resolves to 'No'. Each market closes on October 27, 2026, and expires either when the index value is officially released or one week after the close date, whichever comes first. The Exchange has applied modifications to the Source Agency and Underlying for index markets as per the Kalshi Rulebook.
