Description

This set of markets tracks the performance of a major stock market index on a specific date, resolving based on whether the index closes above various threshold values. Investors and analysts use such markets to speculate or hedge against potential movements in broad market indicators.

Kalshi

All markets resolve based on the end-of-day value of the S&P 500 index on August 21, 2026, with each market having a distinct threshold value. If the index closes above the specified threshold (e.g., 7549.9999, 7554.9999, etc.), the market resolves to 'Yes'; otherwise, it resolves to 'No.' Markets close on August 21, 2026, and expiration occurs at the sooner of the first 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 valuation methodology across all thresholds.
