This set of markets focuses on predicting the performance of a major stock market index at a specific future date and time. Each market has a different threshold value, allowing participants to speculate on whether the index will reach or exceed various levels by the specified deadline.
All markets resolve based on the S&P 500 index value at exactly 2pm EDT on October 26, 2026. For each market, if the index value at that moment exceeds the specified threshold (rounded down to the nearest whole number), the market resolves to 'Yes'; otherwise, it resolves to 'No'. All markets close on October 26, 2026, and expiration occurs at the sooner of the first official data release or one week after the close date. The Exchange has applied specific modifications to the source agency and underlying assets for index-related markets as per the Kalshi Rulebook.
