4-bullet brief | narrative

At 99%, the market treats the Nasdaq-100 clearing 31,000 by Dec 31 as essentially resolved.
42% of all-time Kalshi volume on this contract arrived in 24 hours.
With NDX well above that threshold, volume likely reflects position harvesting near expiry.
Resolves at 4pm EST on December 31, 2026 on the official Nasdaq-100 close.
