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 surpass certain thresholds. The outcome depends solely on the index's value at the exact specified 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 September 8, 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 September 08, 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 as per the Kalshi Rulebook, ensuring consistent data sourcing and valuation methodology across all thresholds.
