This market 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 exceed certain threshold values.
All markets resolve based on the end-of-day value of the Nasdaq 100 index on August 18, 2026, at 4pm EDT. Each market has a specific threshold value; if the index closes above that threshold, the market resolves to 'Yes,' otherwise to 'No.' Markets close on August 18, 2026, and expiration occurs at the sooner of the official data release or one week after the close. All markets adhere to modified source agency and underlying rules for indices as specified in the Kalshi Rulebook.
