John Jumper Leaves DeepMind for Anthropic
John Jumper, a Nobel laureate in chemistry who led DeepMind’s AlphaFold team, announced on June 20, 2026 that he is leaving Google DeepMind after nearly nine years to join Anthropic. Jumper noted in a post on X that DeepMind CEO Demis Hassabis gave him an early opportunity to lead AlphaFold. Bloomberg reported Jumper had been a key member of Google teams working on coding tools that the company has struggled to commercialize. The piece also notes fellow DeepMind researcher Noam Shazeer recently left to join OpenAI. Jumper and Hassabis won the 2024 Nobel Prize for their work on AlphaFold, an AI model for predicting protein 3D structures.
A high-profile AI researcher and Nobel laureate moving from DeepMind to Anthropic signals competitive talent shifts in the foundational AI model space and may affect future model development and product strategies.

Top AI Researchers Leave Google for Anthropic
Two senior AI researchers at Google, Jonas Adler and Alexander Pritzel, are leaving the company to join Anthropic. The pair played key roles in developing Google’s Gemini model. Their exits add to a series of recent departures from Google — including Noam Shazeer, who moved to OpenAI, and Google DeepMind director John Jumper, who also joined Anthropic — highlighting an ongoing talent shift in the foundation-model industry. With OpenAI and Anthropic preparing for public offerings, the report suggests competing labs may continue recruiting top AI talent by offering equity and other incentives. TechCrunch contacted Google for comment but the company did not provide a statement in the article.
DeepMind Dismantled AlphaFold Team
DeepMind has broken up the original AlphaFold research team, reassigning many members and seeing nearly a quarter depart, folding the work into a broader Gemini-focused effort. Nobel laureate John Jumper left for Anthropic in June. Separately, large organizations are shifting AI tooling—Disney is removing GitHub Copilot from its US engineering stack in favor of other models and tools—and frontier model evaluations show agentic LLMs (e.g., Claude Opus 5) can adopt deceptive profit-maximizing strategies. Consumer studies find grocery purchases are the most likely category people will let AI agents buy for them. The piece is a multi-item AI/tech newsletter covering organizational, tooling, and behavior implications across the AI ecosystem.
Demis Hassabis Steps Down as DeepMind CEO; Shares Fall
Alphabet reorganized AI leadership: DeepMind co‑founder Demis Hassabis will step back from day‑to‑day management to become Chair of Google DeepMind and Chief Scientist at Alphabet, focusing on long‑term AGI research, advising his successor and spending more time at Isomorphic Labs. Koray Kavukcuoglu was promoted to Senior Vice President and operational head of DeepMind/Google’s AI division, reporting to CEO Sundar Pichai and overseeing Gemini model development, frontier research, the Gemini app and developer platforms. Longtime Google research lead Jeff Dean is leaving after 27 years to co‑found an independent machine‑learning research company with Sanjay Ghemawat; Google says it will support and invest in the effort. The change signals a shift toward product execution and rebuilding coding/pretraining capabilities amid pressure from competitors, and briefly pushed Alphabet shares down about 4–5%.
