This set of markets focuses on predicting the performance of a major stock market index on a specific date, allowing participants to speculate on whether the index will reach certain threshold values by the end of a set trading day.
All markets in this event resolve based on the end-of-day value of the S&P 500 index on August 11, 2026. Each market has a specific threshold value; if the index closes above the respective threshold (e.g., 7599.9999, 7604.9999, etc.), the market resolves to 'Yes.' Markets close on August 11, 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.
