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 in this event resolve based on the end-of-day value of the S&P 500 index on July 23, 2026. 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 July 23, 2026, and expire either when the index value is first officially released or one week after the close date, whichever comes first. The Exchange has applied modifications to the source agency and underlying for index markets as per the Kalshi Rulebook.
