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 predetermined moment, reflecting broader economic expectations and market sentiment.
All markets share a common resolution mechanism based on the S&P 500 index value at 10am EDT on October 12, 2026. Each market has a distinct threshold: if the index closes above a specific value (e.g., 7,600.9999 or higher), that market resolves to 'Yes'; otherwise, it resolves to 'No'. All markets close on October 12, 2026, and expire either when the index value is first officially released or one week after the specified date, whichever occurs first. The Exchange has applied modifications to the Source Agency and Underlying for index markets as per the Kalshi Rulebook.
