OpenAI Raced a Rumor to Claim a $1M Math Proof
OpenAI says its model solved the Navier-Stokes Millennium Prize Problem after allegedly hearing a rumor about unpublished work by NYU professor Tristan Buckmaster and Anthropic employee Levent Alpöge and matching their approach — Buckmaster alleges an OpenAI researcher pressured him with a publish-or-be-scooped ultimatum, which OpenAI denies.

Flagged:The proof itself and the credit dispute are separately sourced: OpenAI's own post plus Nature and Quanta cover the Lean-verified math (88 hours, ~10,000 concurrent agents, finite-time blowup result), independent of who behaved how. The dispute sequence and quotes (Buckmaster's cheating/intimidation allegations, Bubeck's denial, Tao's 'marketing proof points' / archaeological-site-looting critique) are Fortune's reporting, corroborated by Axios's own account of the same timeline. Every disputed claim is attributed to its source in the captions (Buckmaster alleges / Bubeck denies) rather than stated as settled fact — Bubeck denies intimidation and calls the exchange normal academic negotiation. Alpöge and Buckmaster's own work is confirmed to address a related but distinct problem (forced Euler equations, not Navier-Stokes), per OpenAI's own account of learning this after reaching out. OpenAI brand color #10A37F used for the card's background wordmark, per its own favicon (cross-checked against the existing openai-astra-critical-cyber and openai-agents-wiki-hijack cards' sourcing notes).
