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 1pm EDT on October 5, 2026. Each market has a specific threshold value; if the index closes above that threshold at the specified time, the market resolves to Yes. All markets close on October 05, 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 updated its procedures for determining the source and calculation of index values for these markets, as noted in the Kalshi Rulebook.
