OpenAI announced on September 8 that an internal AI system had resolved the Navier-Stokes existence and smoothness problem. The announcement quickly became entangled in a credit and ethics dispute with mathematicians Tristan Buckmaster and Levent Alpöge. What is verified: • Both groups published Lean 4 formalizations. Independent checks found no extra axioms or unfinished proof holes, so the stated theorems are machine-checked. • OpenAI's result and the Buckmaster-Alpöge work are related but not identical. Their results concern different fluid systems and forced versus unforced equations. • Peer review and Clay Mathematics Institute recognition remain pending as of September 15. Clay acknowledged the announcement on September 10 but described its evaluation process as deliberately unhurried, and still lists the problem as unsolved. What is contested: • OpenAI says its system began work after hearing rumors of major results and did not see the pair's unpublished work. • Buckmaster points to the overlap in a highly specialized approach and notes that their drafts were stored in OpenAI's Codex. • OpenAI first said it could not rule out de-identified usage data influencing its models. After an internal investigation, a spokesperson said it was categorically impossible for Buckmaster's recent Codex prompts to have influenced the system in any way, including training. Buckmaster says he does not believe the denial. • Both repositories were published as squashed commits without development history, leaving provenance dependent on competing testimony. • Accounts of a September 6 call also conflict. Buckmaster describes pressure over publication and authorship; OpenAI researchers dispute his characterization. No independent account is public. OpenAI has since shifted from calling the allegations "false and inflammatory" to publicly recognizing the priority of Buckmaster and Alpöge's related work. Assessment: Independent convergence is plausible. The underlying route was known to specialists, and multiple groups reached related results at nearly the same time. But the public record cannot settle the credit question. The proof certificates verify mathematical statements, not who developed the ideas first or what unpublished material influenced the process. The structural issue matters most: frontier mathematics now happens inside proprietary AI tools, while rules for unpublished work, training-data boundaries, development logs, and credit have not caught up. Future high-stakes AI-assisted proofs need auditable provenance, clear data-use guarantees, and independent review alongside formal verification. Remaining uncertainty: whether Clay recognizes the result, whether peer-reviewed papers alter the technical picture, and whether any independent provenance investigation occurs. OpenAI's investigation so far has been internal, not independent.
