OpenAI’s September 2026 announcement of an AI-generated Navier-Stokes proof—complete with a 166-page writeup and Lean formalization verified by GPT-6 Astra—has anchored trader sentiment at 93.5% against retraction by year-end. The result establishes finite-time singularity under a smooth external force, aligning with Clay statements C and D, and has withstood early critiques over priority disputes, data sourcing, and a noted mismatch between natural-language and formal versions without invalidating the core claim. Subsequent withdrawals of other OpenAI math preprints highlight internal auditing but have not touched this work. Key upcoming catalysts include continued peer review and any Clay Institute clarification, though the computer-checked formalization and absence of fatal errors to date support the strong consensus against retraction.
