OpenAI’s September 2026 announcement of a multi-agent AI system producing a Lean-formalized proof of finite-time singularity for the forced three-dimensional Navier-Stokes equations has shaped current trader sentiment. The Clay Mathematics Institute responded days later by describing the problem as “apparently settled” while stressing its deliberately unhurried evaluation process under established prize rules. Those rules require publication in a qualifying journal, broad community acceptance, and a minimum two-year review period before any official declaration or Millennium Prize award. As of November 2026 the problem remains labeled “Active,” with ongoing scrutiny of the formalization and no peer-reviewed journal version yet. Parallel human-AI results on related forced equations add context but leave the unforced formulation central to the prize unresolved. Near-term resolution hinges on whether the community vetting timeline accelerates or stalls.
