This event tracks the performance of a major stock market index at a specific future date and time, allowing participants to speculate on whether the index will meet or exceed certain threshold values. The outcome depends solely on the index's value at the exact close of trading on the specified date, providing a clear, time-bound resolution point for all associated markets.
All markets share the same resolution criteria based on the S&P 500 index value at 3pm EDT on September 8, 2026. Each market has a unique threshold value; if the index closes above its respective threshold (e.g., 7549.9999, 7554.9999, etc.), that market resolves to 'Yes.' Markets close on September 8, 2026, and expiration occurs at the sooner of the first official data release or one week after the close date. The Exchange has applied specific modifications to the source agency and underlying rules for index markets as per the Kalshi Rulebook, ensuring consistent data sourcing and valuation methodology across all thresholds.
