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 September 01, 2026, at 4pm EDT. For each market, if the index closes above the specified threshold (e.g., 7549.9999, 7554.9999, etc.), the market resolves to 'Yes'; otherwise, it resolves to 'No'. Markets close on September 01, 2026, and expiration occurs at the sooner of the first official release of the index value or one week after the close date. The Exchange has applied modifications to the Source Agency and Underlying for index markets as per the Kalshi Rulebook.
