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 and market sentiment predictions.
All markets share a common resolution framework centered on the S&P 500 index value at 1pm EDT on October 19, 2026. Each market has a unique threshold, and if the index closes above that threshold, the 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 closing date. All markets adhere to modified source agency and underlying rules specific to indices as outlined in the Kalshi Rulebook.
