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.
All markets share a common resolution mechanism based on the S&P 500 index value at 3pm EDT on October 19, 2026. Each market has a distinct threshold: if the index closes above the specified value (e.g., 7574.9999, 7579.9999, etc.), it resolves to 'Yes'; otherwise, it resolves to 'No.' Markets close on October 19, 2026, and expiration occurs at the sooner of the first official data release or one week after that date. All markets adhere to modified source agency and underlying rules for indices as per the Kalshi Rulebook.
