This set of markets tracks the performance of a major stock market index at a specific future date and time. Each market represents a different threshold value that the index must exceed to settle as 'Yes'. The outcome reflects whether the index reaches or surpasses these thresholds at the specified moment.
All markets share the same core resolution mechanism: they resolve based on whether the S&P 500 index value at 1pm EDT on September 14, 2026 exceeds a specific threshold, rounded down to the nearest integer. Each market features a distinct threshold (e.g., 7,425, 7,430, up to 7,720), with the 'Yes' outcome triggered if the index closes above that precise threshold. Markets close on the event date and expire either upon the first official data release or one week afterward, whichever occurs first. All markets utilize modified source agency and underlying rules specific to index markets as outlined in the Kalshi Rulebook.
