Tristan Buckmaster’s public allegations of misconduct during OpenAI’s Navier-Stokes research form the main driver behind low trader odds on an imminent lawsuit. In early September 2026, the NYU mathematician and Anthropic collaborator Levent Alpöge detailed year-long progress on fluid-equation blowup proofs using large language models and private Codex sessions; they accused OpenAI of learning their approach after a leak, then deploying intensive compute via thousands of agents to produce a parallel 100-plus-page proof. Buckmaster described calls with Sébastien Bubeck involving authorship pressure to exclude the Anthropic researcher and implied career risks, while OpenAI and Sam Altman maintained the work was independent and denied accessing specific user data, though they could not fully rule out de-identified training influence. No filings or new escalations have emerged in the subsequent month, reflecting the civil, credit-focused nature of the dispute and limited immediate legal thresholds.
