This set of markets tracks potential future performance of a major stock market index on a specific date and time. Each market represents a different threshold value that the index must exceed to settle, allowing participants to speculate on various levels of market performance.
All markets share identical secondary rules and resolution mechanics. Each market resolves to 'Yes' if the S&P 500 index value at 4pm EDT on September 14, 2026 exceeds a specific threshold (e.g., 7424.9999, 7429.9999, etc.). Markets close on September 14, 2026, and expire either when the index value is first officially released or one week after the close date, whichever occurs sooner. The Exchange has applied modifications to the source agency and underlying assets for all index-based markets per the Kalshi Rulebook.
