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 expectations and market sentiment.
All markets share the same resolution criteria: each resolves to 'Yes' if the S&P 500 index value at 10am EDT on October 19, 2026 exceeds a specific threshold (e.g., 7574.9999, 7579.9999, etc.). The 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 specified in the Kalshi Rulebook.
