Description

This set of markets tracks whether the S&P 500 index will close above specific threshold values on a particular date. Each market represents a different numerical threshold, allowing participants to speculate on the exact level of the index at the end of trading on that day.

Kalshi

All markets in this set share the same core resolution mechanism and secondary rules. Each market resolves to 'Yes' if the closing value of the S&P 500 index on August 18, 2026, exceeds a specific threshold (e.g., 7624.9999, 7629.9999, etc.). The markets close on August 18, 2026, and expiration occurs at the sooner of the official data release or one week after the closing 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 market definitions across all thresholds.
