OpenAI’s September 8, 2026 announcement of an AI-generated proof for statements C and D of the Navier-Stokes existence and smoothness problem, backed by a public Lean formalization, has driven strong trader consensus against retraction. An internal multi-agent system powered by an unreleased model exceeding GPT-6 Astra capabilities ran roughly 10,000 agents for 88 hours, producing both an analytical write-up and mechanically verifiable Lean code that demonstrates finite-time singularity formation under smooth forcing while preserving finite energy. Ongoing debates center on research priority with concurrent NYU-Anthropic work and data provenance rather than outright invalidity, and no independent mathematicians have yet identified errors in the formalization. With only days elapsed since publication, realistic challenges remain possible if subsequent peer scrutiny reveals mismatches between the Lean artifact and Clay criteria or uncovers subtle logical gaps, though the combination of formal verification and substantial compute investment currently anchors the 93% implied probability that OpenAI will stand by the result through year-end.
