This set of markets tracks whether the S&P 500 index will reach or exceed various threshold values at a specific future date and time. Each market corresponds to a different numerical threshold, allowing participants to speculate on the precise level of the index at that moment.
All markets resolve based on the S&P 500 index value at 12pm EDT on October 26, 2026. Each individual market has a unique threshold value; if the index closes at or above that threshold during the specified time, the market resolves to 'Yes,' otherwise 'No.' Markets close on October 26, 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 specific to indices as outlined in the Kalshi Rulebook.
