Description

This event tracks the performance of a major stock market index at a specific future date and time, allowing participants to speculate on whether the index will surpass certain thresholds. The outcome depends solely on the index's value at the exact closing moment, reflecting broader economic expectations and market sentiment.

Kalshi

All markets share a common resolution mechanism based on the S&P 500 index value at 1pm EDT on August 31, 2026. Each market has a distinct threshold, and if the index closes above its respective threshold, that market resolves to 'Yes'; otherwise, it resolves to 'No'. Markets close on August 31, 2026, and expiration occurs at the sooner of the first official data release or one week after the closing date. All markets adhere to modified source agency and underlying rules specific to indices as outlined in the Kalshi Rulebook.
