This set of markets tracks whether the S&P 500 index will close above specific thresholds on a particular date. Each market corresponds to a different price level, allowing participants to speculate on the exact magnitude of the index's performance at that moment.
All markets resolve based on the end-of-day value of the S&P 500 index on October 08, 2026. For each market, if the index closes above the specified threshold (e.g., 7649.9999, 7654.9999, etc.), the market resolves to 'Yes'; otherwise, it resolves to 'No'. All markets close on October 08, 2026, and expiration occurs at the sooner of the first official release of the index value 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.
