Unified Resolution Criteria (Consistent across platforms)

Both platforms define resolution based on the same event – an announcement of engagement or marriage – and accept similar sources for verification.Primary resolution logic: Official statements from Katy Perry and/or Justin Trudeau or their official representatives, with credible reporting as a secondary source.

Core resolution logic:

  • Resolution is triggered by an announcement of engagement or marriage.
  • Acceptable sources include official statements from Perry or Trudeau, or their representatives.
  • Credible reporting will be used as a secondary source if official statements are unavailable.

Edge cases & clarifications:

  • Rumors/Speculation: Unconfirmed rumors or speculation will not be sufficient for resolution. Only official announcements or credible reporting will be considered.
  • Cancellation of Engagement: If an engagement is announced but later cancelled before the end of 2026, the market will still resolve to 'Yes' as the initial announcement fulfills the condition.
