This market tracks the performance of a major stock market index on a specific date and time, allowing participants to speculate on whether the index will surpass certain threshold values.
The market resolves based on the Nasdaq 100 index value at 11am EDT on October 12, 2026. Each market has a unique threshold; if the index closes above the specified threshold (e.g., 28,699.99, 28,709.99, etc.), that market resolves to 'Yes.' All markets close on October 12, 2026, and expire either when the index value is first officially released or one week after the close date, whichever comes first. The Exchange has adjusted data sources for index markets per the Kalshi Rulebook.
