The record since

  • 21 Aug 26 No. 52 · revised to 85%
    Reuters-reviewed satellite imagery (Aug 19-20) shows Antelope Reef's first-phase island complete with a 680m wharf and deep-water harbor, and CSIS says initial excavation for the runway itself has already begun — sharply de-risking the resolution well inside the 12-month window.

What would overturn it

A full year of stalled reclamation with no beach-to-runway earthworks visible in satellite imagery would be the signal against it.

The verdict

Open  Resolves by 19 Aug 27 — graded at the weekly Reckoning against the criteria above, and recorded here.

As logged at issue

Roughly even odds satellite imagery shows visible runway-grading work at Antelope Reef within 12 months (by 19 August 2027), matching the construction sequence China used before militarizing its Spratly outposts; a full year of stalled reclamation with no beach-to-runway earthworks would be the signal against it.
