This event tracks the performance of a major stock market index at a specific future date and time, allowing participants to speculate on whether the index will meet or exceed certain threshold values. The outcome depends solely on the index's value at the predetermined moment, reflecting broader economic expectations and market sentiment.
All markets share the same core resolution mechanism: each market resolves to 'Yes' if the S&P 500 index value at 11am EDT on August 10, 2026, exceeds a specific threshold (e.g., 7549.9999, 7554.9999, etc.). Thresholds vary incrementally across markets, creating a range of possible outcomes. All markets close on August 10, 2026, and expiration occurs at the sooner of the first official data release or one week after the specified date. The Exchange has applied modifications to the Source Agency and Underlying for index markets per the Kalshi Rulebook, ensuring consistent data sourcing and validation processes across all thresholds.
