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 surpass certain threshold values.
Each market resolves to "Yes" if the Nasdaq 100 index value at 11am EDT on September 21, 2026 exceeds a specified threshold, ranging from 27,400 to 31,390 in increments of 10. All markets close on September 21, 2026, and expire either when the index value is first reported or one week after the close date, whichever comes first. The rules consistently define resolution based on the index value crossing the threshold and share identical closing and expiration mechanics across all thresholds.
