This set of markets tracks potential future performance of a major stock market index on a specific date. Each market represents a different threshold value that the index must exceed to settle, allowing participants to speculate on various levels of market performance.
All markets resolve based on the end-of-day S&P 500 index value on October 07, 2026. For each market, if the index closes above a specified threshold (e.g., 7,600.9999 or higher), the market resolves to 'Yes'; otherwise, it resolves to 'No'. All markets close on October 07, 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 as per the Kalshi Rulebook, ensuring consistent data sourcing and valuation methodology across all threshold-based markets.
