This set of markets tracks 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 depends purely on the index's level at the exact specified moment.
All markets share identical event-level rules governing their resolution. Each market resolves to 'Yes' if the S&P 500 index value at precisely 1pm EDT on August 24, 2026 exceeds a specific threshold defined in the market's primary rule (e.g., above 7474.9999, above 7479.9999, etc.). The markets close on August 24, 2026, and expiration occurs at the sooner of the first official data release or one week after that date. All markets utilize modified source agency and underlying rules as specified in the Kalshi Rulebook for indices, ensuring consistent data sourcing and valuation methodology across all threshold-based contracts.
