How this market settles

If construction begins on the proposed United States Triumphal Arch in Washington, D.C. after Issuance and before Dec 1, 2026, then the market resolves to Yes. Only reporting from any of the Source Agencies qualifies for the purposes of this market. Reports that merely reference prior publications (from before Issuance) do not qualify. Republishing of content originally produced by other sources (e.g., wire services) only qualifies if the content is hosted on the outlet's official platform and the outlet is clearly identified as the publishing entity.

What could still go wrong

  • The specific 'Source Agencies' are not listed or defined in the provided metadata, creating ambiguity about which outlets qualify.
  • 'Construction begins' is not precisely defined — it is unclear whether groundbreaking ceremonies, site preparation, excavation, or structural work constitutes the threshold.
  • The 'Issuance' date is referenced but not explicitly stated in the provided metadata.
  • The proposed United States Triumphal Arch is described as 'proposed,' raising uncertainty about whether any official project exists that could be under construction.
  • No official governmental or authoritative source is specified for confirming construction commencement.
  • Timezone of the December 1, 2026 deadline (04:59Z) could create ambiguity for reports published near the cutoff.
