Tier B — AI-reviewed by GPT-6 Luna, evidence as of 2026-10-19.
As of 2026-10-19 23:03 UTC — source: Polyscan AI review, n=1 for this pair
The review confirmed one divergence: “Vessel entry into maritime territory”.
The phrase the review relied on most, one per venue: Kalshi: “Exiting within the area constitutes a visit regardless of duration or method of exit.” Polymarket: “physically entering the terrestrial or maritime territory of Greenland”
I matched Kalshi's before-Jan-1, 2027 market to the Polymarket Dec 31, 2026 variant in the cited event; its March 31 variant is a separate horizon. On the aligned dates, Trump remaining aboard a vessel entering Greenland's territorial waters could resolve YES on Polymarket and NO on Kalshi.
