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 set resolve based on the end-of-day value of the S&P 500 index on September 03, 2026, at 4pm EDT. A market resolves to "Yes" if the index closes above the specified threshold (e.g., 7474.9999, 7479.9999, etc.). Each market has its own threshold, creating a range of possible outcomes depending on the index's closing value. All markets close on September 03, 2026, and expire at the sooner of the first official release of the index data or one week after the close date. The Exchange has modified the Source Agency and Underlying for indices markets per the Kalshi Rulebook, which may affect data sourcing and resolution procedures but does not alter the core resolution mechanism tied to the index's closing value.
