This set of markets tracks the performance of a major stock market index at a specific future date and time. Each market has a different threshold value, allowing participants to speculate on whether the index will reach or exceed various levels by the specified moment.
All markets in this event resolve based on the S&P 500 index value at 11am EDT on August 24, 2026. Each individual market has a unique threshold, and resolves to 'Yes' if the index value exceeds that threshold at the specified time. Markets close on August 24, 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 index markets as outlined in the Kalshi Rulebook.
