This set of markets focuses on predicting the performance of a major stock market index at a specific future date and time. Each market represents a different threshold value that the index must exceed to settle as 'Yes'. The outcome depends entirely on the index's value at the exact closing moment on August 24, 2026, at 4pm EDT.
All markets share a common resolution mechanism based on the S&P 500 index value at 4pm EDT on August 24, 2026. Each individual market has a unique threshold, specified as a numerical value (e.g., 7474.9999, 7479.9999, etc.). If the index value at the specified time is strictly above the respective threshold, that market resolves to 'Yes'; otherwise, it resolves to 'No'. All markets close on August 24, 2026, and expiration occurs at the sooner of the first official data release or one week after the closing date. The Exchange has applied specific modifications to the source agency and underlying assets for index-related markets as per the Kalshi Rulebook.
