This market tracks the performance of a widely followed stock market index on a specific date, allowing participants to speculate on whether the index will surpass certain thresholds by the close of trading on that day.
All markets resolve based on the end-of-day value of the Nasdaq 100 index on October 22, 2026, at 4pm EDT. Each market has a specific threshold: if the index closes above the stated threshold (e.g., 27,399.99, 27,409.99, etc.), the market resolves to 'Yes'; otherwise, it resolves to 'No.' All markets close on October 22, 2026, and expire either when the index value is officially released or one week after the close, whichever comes first. The rules consistently reference the modified source agency and underlying for indices as per the Kalshi Rulebook.
