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, allowing participants to speculate on the index's level at that precise moment.
All markets in this event resolve based on the S&P 500 index value at 2pm EDT on October 19, 2026. Each individual market has a unique threshold, and resolves to 'Yes' if the index closes above that specific threshold at the specified time. Markets close on October 19, 2026, and expire either when the index data is first released or one week after the close date, whichever comes first. The Exchange has applied modifications to the Source Agency and Underlying for index markets as per the Kalshi Rulebook.
