This set of markets tracks the performance of a major stock market index at a specific moment in the future. Each market represents a different threshold value that the index must exceed to settle as 'Yes'. These markets allow participants to speculate or hedge on the future direction of market performance without directly investing in stocks.
All markets share a common resolution framework centered on the S&P 500 index value at 2pm EDT on September 8, 2026. Each individual market resolves to 'Yes' if the index closes above a specific threshold (e.g., 7550, 7555, etc.) at that exact time, with thresholds varying incrementally across markets. The markets close on September 08, 2026, and expiration occurs at the sooner of the first official data release or one week after the specified date. All markets adhere to modified source agency and underlying rules for indices as outlined in the Kalshi Rulebook, ensuring consistent data sourcing and validation procedures across the entire set of markets.
