Nobel Prize-winning AI researcher John Jumper leaves Google DeepMind for Anthropic

Jun 19, 2026

Nobel Prize-winning AI researcher John Jumper is leaving Google DeepMind after nearly nine years to join rival lab Anthropic. Jumper, who co-won the 2024 Nobel in Chemistry for leading the team that developed the revolutionary AlphaFold protein-prediction system, is the latest high-profile scientist to depart Google for an AI startup. His move underscores the intense competition for top talent in the field.

Jumper joins Anthropic

▪John Jumper announced on June 19, 2026, that he is leaving Google DeepMind to join rival AI lab Anthropic.
▪Before starting at Anthropic, John Jumper plans to take time off to "recharge."
▪John Jumper has not publicly stated what his new role at Anthropic will be.
▪John Jumper worked at Google DeepMind for nearly nine years.

AlphaFold Nobel Prize winner

▪The 2024 Nobel Prize in Chemistry was awarded for the development of AlphaFold.
▪Demis Hassabis hired John Jumper to lead the AlphaFold team just six months after Jumper finished his PhD.
▪John Jumper and Google DeepMind CEO Demis Hassabis shared the 2024 Nobel Prize in Chemistry.

DeepMind talent exodus

▪John Jumper's departure follows other high-profile researchers leaving Google, including Noam Shazeer who joined OpenAI and David Silver who founded a startup.
▪AI startups like Anthropic and OpenAI are considered highly desirable employers in the tech industry, with both reportedly preparing for initial public offerings.
▪A trend exists of top talent leaving established tech companies like Google and Meta for AI startups such as Anthropic and OpenAI.

Protein structure prediction legacy

▪Demis Hassabis stated that the work on AlphaFold "changed the world" and demonstrated AI's potential to benefit humanity.
▪AlphaFold is an AI system that predicts a protein's 3D structure from its amino acid sequence, a breakthrough that solved a decades-old scientific challenge.
▪The AlphaFold system provides over 200 million protein structure predictions, significantly accelerating biological and medical research by months or years.
▪Upon winning the Nobel Prize, John Jumper credited his team at Google DeepMind and stated AI is a tool to make science faster.
