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 29, 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.' Markets close on July 29, 2026, and expiration occurs at the sooner of the first official release of the index value or one week after the close date. All markets adhere to modified source agency and underlying rules for indices as specified in the Kalshi Rulebook.
