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 might surpass, allowing participants to speculate on various levels of market performance.
All markets resolve based on the S&P 500 index value at 11am EDT on August 31, 2026. For each market, if the index value exceeds a specified threshold (e.g., 7574.9999, 7579.9999, etc.), the market resolves to 'Yes'; otherwise, it resolves to 'No'. Markets close on August 31, 2026, and expiration occurs at the sooner of the first official data release or one week after the close date. All markets adhere to modified source agency and underlying rules for indices as per the Kalshi Rulebook.
