Carver Signal Narrative

Recent developments are unrelated background matters (state insurance rules, e‑cigarette guidance disputes) and a mifepristone brief that, while supporting FDA authority, doesn’t directly affect Retatrutide. No targeted regulatory pressure is evident; odds hinge on standard FDA review and clinical data. The FDA decision for 2026 remains pending.

Resolution criteria

This market will resolve to 'Yes' if the U.S. Food and Drug Administration formally approves Retatrutide (LY3437943, Eli Lilly's triple GIP/GLP-1/glucagon receptor agonist) for any indication by December 31, 2026, 11:59 PM ET. Approval must be via formal FDA authorization — a New Drug Application (NDA) or Biologics License Application (BLA) approval letter. Excludes Emergency Use Authorizations (EUA), compassionate use designations, tentative approvals, and approvable letters. Retatrutide targets obesity, type 2 diabetes, and related metabolic conditions. Phase 3 clinical trial data is expected in 2026, with NDA submission expected no earlier than late 2026, making a 2026 FDA decision unlikely but possible on accelerated review pathways.
