This set of markets tracks the performance of a major stock market index on a specific date, resolving based on whether the index closes above various threshold values. Each market represents a different threshold, allowing participants to speculate on the exact level of market performance at the close of trading on that day.
All markets resolve based on the end-of-day value of the S&P 500 index on September 08, 2026, at 4pm EDT. Each individual market has a specific threshold value; if the index closes above that threshold (rounded down to four decimal places), the market resolves to 'Yes,' otherwise to 'No.' All markets close on September 08, 2026, and expire either when the index value is officially released or one week after the close date, whichever occurs first. The Exchange has applied modifications to the Source Agency and Underlying for index markets as per the Kalshi Rulebook.
