John Jumper Moves to Anthropic

John Jumper announced on June 19, 2026 that he is leaving Google DeepMind to join Anthropic. Jumper is the computational chemist who led the development of AlphaFold and shared the 2024 Nobel Prize in Chemistry with Demis Hassabis.

The AlphaFold2 database is now used by more than 2 million researchers across 190 countries, and achieved accuracy comparable to experimental methods at the CASP14 competition in 2020.

Anthropic’s Expanding Science Infrastructure

Anthropric has been actively building AI-for-science infrastructure throughout 2026, including wet labs, biological agent research, and partnerships with the Allen Institute and Howard Hughes Medical Institute. The company is hosting a science-focused event on June 30.

Broader Talent Exodus from Google

Jumper’s move is part of a wider reshuffling of AI talent. Noam Shazeer, co-author of the 2017 ‘Attention Is All You Need’ paper that introduced the Transformer architecture, announced on June 18, 2026 that he was leaving Google DeepMind for OpenAI. Google paid approximately $2.7 billion in 2024 to bring Shazeer back from Character.AI.

Jonas Adler and Alexander Pritzel are also leaving Google for Anthropic, according to Bloomberg. Both played key roles in the development of Google’s Gemini model.

Anthropic’s Competitive Strength

Anthropric has an 80 percent two-year retention rate of employees, ahead of DeepMind at 78 percent and OpenAI at 67 percent. According to SignalFire’s 2025 State of Talent Report, engineers at DeepMind were nearly 11 times more likely to leave for Anthropic than the reverse.

The company’s growth has accelerated dramatically: annualized revenue grew from roughly $9 billion at the end of 2025 to more than $47 billion by May 2026. Anthropic overtook OpenAI in U.S. business AI payments for the first time as of April 2026.

Anthropric filed confidential IPO paperwork on June 1 at a $965 billion valuation.
