These markets track whether the S&P 500 index will surpass specific thresholds by the close of trading on September 24, 2026. Each threshold represents a distinct level the index must exceed for the corresponding market to settle positively. The outcomes reflect expectations about long-term market performance and economic conditions.
All markets share a common resolution framework centered on the end-of-day S&P 500 index value on September 24, 2026. Each market specifies a unique numerical threshold; if the index closes above that threshold, the market resolves to 'Yes,' indicating the threshold was met. Markets close on September 24, 2026, and expiration occurs either when the index data is first released or one week after the close date, whichever comes first. The Exchange has applied modifications to the source agency and underlying for all index-based markets as per the Kalshi Rulebook, ensuring consistent data sourcing and definition across all thresholds.
