Description

This set of markets tracks potential future performance of a major stock market index on a specific date. Each market represents a different threshold value that the index must exceed to settle as 'Yes'. The outcomes reflect investor expectations about economic conditions and market trends over the specified period.

Kalshi

All markets share identical settlement mechanics and secondary rules, differing only in their threshold values. Each market resolves to 'Yes' if the S&P 500 index closes above a specific numerical threshold on August 28, 2026 at 4pm EDT. Markets close on the settlement date and expire either when the index value is officially released or one week afterward, whichever occurs first. The Exchange has applied standardized modifications to source agency and underlying definitions for all index-based markets as per the Kalshi Rulebook.
