This set of markets focuses on predicting the performance of a major stock market index on a specific future date. Each market represents a different threshold value that the index must exceed to settle as 'Yes'. The outcome depends entirely on the index's closing value at the specified time, reflecting investor sentiment and economic expectations for that period.
All markets resolve based on the end-of-day value of the S&P 500 index on August 05, 2026, at 4pm EDT. Each individual market has a specific threshold: if the index closes above the stated threshold (e.g., 7,450.9999 or higher), that market resolves to 'Yes'; otherwise, it resolves to 'No'. All markets close on August 05, 2026, and expiration occurs at the sooner of the first official release of the index value or one week after the closing date. The Exchange has applied modifications to the Source Agency and Underlying for index markets as per the Kalshi Rulebook, ensuring consistent data sourcing and valuation methodology across all thresholds.
