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 for the outcome to be considered successful. The resolution depends solely on the index's value at the exact specified moment.
All markets resolve based on the S&P 500 index value at 10am EDT on August 3, 2026. Each individual market has a unique threshold, and resolves to 'Yes' if the index value at that precise time exceeds the respective threshold (e.g., 7274.9999, 7279.9999, etc.). Markets close on August 03, 2026, and expire either when the index value is first officially released or one week after the specified date, whichever occurs first. The Exchange has applied specific modifications to the Source Agency and Underlying for indices markets as detailed in the Kalshi Rulebook.
