This set of markets focuses on predicting the performance of a major stock market index at a specific future date and time. Each market has a different threshold value, allowing participants to bet on whether the index will surpass various levels by the specified deadline.
All markets resolve based on the S&P 500 index value at 4pm EDT on October 12, 2026. A 'Yes' outcome occurs if the index closes above the respective threshold for each market (e.g., 7,600.9999, 7,605.9999, etc.). Each market closes on October 12, 2026, and expires either upon the first official release of the index data or one week after the close date, whichever comes first. The Exchange has applied specific modifications to the source agency and underlying assets for index-related markets as detailed in the Kalshi Rulebook.
