OpenAI’s recent public release of a Lean-formalized proof for a finite-time singularity in the Navier-Stokes equations has anchored trader confidence against retraction. The September 8 announcement detailed an internal model and 10,000-agent effort that produced both an analytical write-up and machine-verifiable formalization, establishing Clay statements C and D while explicitly declining the Millennium Prize. Ongoing scrutiny centers on research conduct allegations rather than mathematical errors, and the public GitHub repository enables rapid independent checks. With the Clay Institute’s review process and potential peer validation still ahead through year-end, the 84.5% market-implied probability reflects consensus that verifiable artifacts and lack of identified flaws make a full retraction improbable absent major new discrepancies.
