Jacob Coxon, the 27-year-old AI researcher whose resignation from Anthropic triggered online fervor and Capitol Hill concern, told Axios he does not profit from inflating Anthropic’s market cap due to unvested shares. His Wikipedia article was created Wednesday, marking his notability. Coxon was interviewed by Wired and responded to Taylor Lorenz’s 'doomer posting' critique by telling Time the term is 'insane' given public CEO statements.

Per Business Insider, he worked at OpenAI in 2023 on GPT-4o, joined Anthropic in 2026, and quit this week. His Wall Street Journal exclusive preceded his viral statements, including the campfire-ready line: 'The people building AI earnestly believe that it could kill us all by the end of the decade.' He clarified the race dynamic in AI could lead to uncontrollable outcomes. Sheryl Crow was reportedly scared by his message.

Evan Hubinger, Anthropic alignment lead, confirmed on X: 'Jacob is correct here—we really do earnestly believe AI could kill all humans!' adding personal belief of >10% risk within decade. Coxon cited timing and sandbox escape incidents for his viral reach. He admires 'AI 2027' and 'AI 2040' and may pursue independent commentary or work in AI auditing/regulation if doom doesn’t materialize.
