This market tracks the performance of a major stock market index on a specific future date, allowing participants to speculate on whether the index will surpass certain threshold values by that time.
The market resolves based on the end-of-day value of the Nasdaq 100 index on September 04, 2026. Each market has a specific threshold value; if the index closes above that threshold on the specified date, the market resolves to Yes. All markets close on September 04, 2026, and expiration occurs at the sooner of the first official data release or one week after the closing date. The Exchange has updated the source agency and underlying rules for index markets as per the Kalshi Rulebook.
