Nobel laureate John Jumper leaves Google DeepMind for Anthropic as talent drains from Google's AI crown jewel

John Jumper, Nobel laureate and co-creator of AlphaFold, announced on June 19, 2026 that he is leaving Google DeepMind after nearly nine years to join Anthropic. The move follows Gemini co-lead Noam Shazeer's departure to OpenAI days earlier, marking a serious week of talent loss for Google's AI division. Anthropic has been building dedicated AI-for-science infrastructure throughout 2026, including wet labs and partnerships with the Allen Institute and Howard Hughes Medical Institute.
