This set of markets tracks 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 for the outcome to be considered successful. These markets allow participants to speculate on or hedge against potential future movements in the index.
All markets in this event resolve based on the S&P 500 index value at 12pm EDT on August 10, 2026. Each individual market has a specific threshold value (e.g., 7,550, 7,555, etc.), and resolves to 'Yes' if the index value at the specified time exceeds that threshold. Markets close on August 10, 2026, and expiration occurs at the sooner of the first official data release or one week after the specified date. All markets follow the same closing and expiration procedures, and the Exchange has applied modifications to the Source Agency and Underlying for index markets as per the Kalshi Rulebook.
