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 to settle as 'Yes'. Investors use these markets to speculate on or hedge against potential movements in the broader market.
All markets resolve based on the S&P 500 index value at 1pm EDT on October 12, 2026. Each individual market has a specific threshold: if the index closes above the stated threshold (e.g., 7,600.9999 or higher), that market resolves to 'Yes'; otherwise, it resolves to 'No'. All markets close on October 12, 2026, and expiration occurs at the sooner of the first official data release or one week after the close date. The Exchange has applied modifications to the Source Agency and Underlying for index markets per the Kalshi Rulebook, ensuring consistent data sourcing and validation processes across all thresholds.
