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. The resolution depends solely on the index's value at the exact specified moment.

Kalshi

All markets share identical secondary rules and resolution timing. Each market resolves to 'Yes' if the S&P 500 index value at 10am EDT on September 21, 2026 exceeds a specific threshold defined in the primary rule (e.g., above 7474.9999, above 7479.9999, etc.). The market closes on September 21, 2026, and expires either when the index value is first officially released or one week after the specified date, whichever occurs sooner. The Exchange has applied modifications to the source agency and underlying for all index-based markets as per the Kalshi Rulebook.
