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 moment of evaluation, reflecting broader economic and market conditions projected into the future.
Each market within this event resolves based on whether the S&P 500 index value at 12pm EDT on October 12, 2026, exceeds a specific threshold, ranging incrementally from 7,600 to 7,895. All markets share identical secondary rules: they close on October 12, 2026, and expire either upon the first official release of the index data or one week after the specified date, whichever occurs sooner. The Exchange has applied modifications to the Source Agency and Underlying for index markets as detailed in the Kalshi Rulebook. Resolution for each market is binary—'Yes' if the index closes above the respective threshold, 'No' otherwise—with all markets evaluated simultaneously based on the same underlying data point.
