This set of markets focuses on predicting 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 various levels by the specified deadline.
All markets resolve based on the closing value of the S&P 500 index at 3pm EDT on September 14, 2026. Each individual market has a unique threshold value; if the index closes at or above that threshold, the market resolves to 'Yes,' otherwise it resolves to 'No.' Markets close on the evaluation date and expire either when the index value is officially released or one week after the closing date, whichever comes first. All markets adhere to modified source agency and underlying rules specific to index markets as outlined in the Kalshi Rulebook.
