Kalshi
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.
Multiple markets exist with varying threshold values for the Nasdaq-100 index closing value on September 17, 2026. Each market resolves to 'Yes' if the index closes above its specific threshold and 'No' otherwise. All markets close on September 17, 2026, and expire either when the index value is officially released or one week after the close date, whichever comes first. The rules reference modifications to data sources per the Kalshi Rulebook for index markets but do not alter the core resolution mechanics described.
