This set of markets tracks potential future performance of a major stock market index on a specific date and time. Each market represents a different threshold value that the index might surpass, allowing participants to speculate on various levels of market performance at that moment.
All markets share the same event date and time (August 3, 2026 at 1pm EDT) and resolve based on the S&P 500 index value at that specific moment. Each individual market has a unique threshold value; if the index closes above its respective threshold at the specified time, that market resolves to 'Yes.' All markets close on August 03, 2026, and expire either when the index data is first released or one week after the event date, whichever comes first. The Exchange has applied specific modifications to the source agency and underlying for index markets as detailed in the Kalshi Rulebook.
