Description

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 for the outcome to be considered successful. These markets allow participants to speculate on or hedge against potential future movements in the index.

Kalshi

All markets share the same core resolution mechanism: each resolves to 'Yes' if the S&P 500 index value at 1pm EDT on September 21, 2026 exceeds its specific threshold (e.g., 7474.9999, 7479.9999, etc.). The thresholds vary incrementally across markets, creating a range of possible outcomes. All markets close on September 21, 2026, and expiration occurs at the sooner of the first official data release or one week after that date. The Exchange has applied specific modifications to the source agency and underlying assets for all index-based markets as per the Kalshi Rulebook.
