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's value.
All markets in this event resolve based on the S&P 500 index value at 11am EDT on September 14, 2026. Each individual market has a specific threshold value (e.g., 7,425 or above, 7,430 or above, etc.), and resolves to "Yes" if the index value at the specified time exceeds that threshold. Markets close on September 14, 2026, and expire either when the index data is first released or one week after the specified date, whichever occurs first. The Exchange has applied modifications to the Source Agency and Underlying for index markets as per the Kalshi Rulebook.
