OpenAI’s September 2026 announcement that an internal multi-agent AI system produced a Lean-formalized proof of finite-time singularity in the forced three-dimensional Navier-Stokes equations has driven recent trader sentiment, though CMI immediately described the problem as only “apparently settled.” The institute’s rules require peer-reviewed publication in a qualifying journal, broad community acceptance, and a two-year waiting period before any declaration, leaving the problem officially active as of late October. Parallel human-AI results on related forced Euler and Boussinesq equations by Buckmaster and Alpöge have added context but do not resolve the unforced case central to the prize formulation. Ongoing scrutiny, including an October arXiv note questioning semantic fidelity of the Lean formalization, and the absence of an accepted journal paper keep resolution timelines uncertain despite the computational milestone.
