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 the future health and growth of the broader market.
All markets share the same event-level rules and resolve based on the S&P 500 index value at 12pm EDT on September 14, 2026. Each individual market has a unique threshold: if the index closes above the specified threshold (e.g., 7424.9999, 7429.9999, etc.) at that exact time, the market resolves to 'Yes'; otherwise, it resolves to 'No.' All markets close on September 14, 2026, and expiration occurs at the sooner of the first official data release or one week after the close date. The Exchange has applied specific modifications to the source agency and underlying assets for index markets as per the Kalshi Rulebook.
