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 the index 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 24, 2026, at 4pm EDT. Each individual market has a specific threshold value; if the index closes above that threshold, the market resolves to 'Yes,' otherwise to 'No.' All markets close on July 24, 2026, and expiration occurs at the sooner of the first official release of the index value 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, but these modifications do not alter the fundamental resolution mechanism described above.
