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. Investors and analysts use such markets to speculate or hedge against potential movements in broad market trends.
All markets resolve based on the end-of-day value of the S&P 500 index on August 27, 2026, at 4pm EDT. Each market has a specific threshold; if the index closes above that threshold (e.g., 7524.9999 or higher for the first market), it resolves to 'Yes.' Markets close on August 27, 2026, and expiration occurs either when the index value is first officially released or one week after the closing date, whichever comes first. All markets adhere to modified source agency and underlying rules for indices as specified in the Kalshi Rulebook.
