This set of markets tracks whether the S&P 500 index will close above specific thresholds on a particular date. Each market represents 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 13, 2026. Each individual market has a unique threshold: if the index closes above its specified value (e.g., 7650, 7655, etc.), that market resolves to 'Yes'; otherwise, it resolves to 'No'. All markets close on October 13, 2026, and expiration occurs at the sooner of the official data release or one week after that date. The Exchange has applied specific modifications to the source agency and underlying assets for index-related markets as detailed in the Kalshi Rulebook.
