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 predetermined moment, reflecting broader economic and market conditions projected into the future.
All markets share a common resolution mechanism based on the S&P 500 index value at 12pm EDT on October 19, 2026. Each market has a distinct threshold: if the index closes above a specific value (e.g., 7574.9999, 7579.9999, etc.), that market 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 the close date. All markets adhere to modified source agency and underlying rules for indices as per the Kalshi Rulebook.
