Nobel Laureate John Jumper Departs Google DeepMind for Anthropic

• From breakthrough science to Nobel Prize
• Nearly a decade at Google DeepMind
• Public departure and DeepMind’s response
• Shift toward AI startups

Nobel Laureate John Jumper Departs Google DeepMind for Anthropic Nobel-winning AI researcher John Jumper is leaving Google DeepMind for rival lab Anthropic, underscoring an intensifying talent battle at the top of the artificial intelligence industry.

§From breakthrough science to Nobel Prize

In 2024, Jumper and Google DeepMind CEO Demis Hassabis shared the Nobel Prize in Chemistry for developing AlphaFold2, an open-source AI model that predicts the 3D structure of proteins, enabling the structure of “virtually all the 200 million proteins that researchers have identified.” The Nobel committee said the work “opens up vast possibilities” for areas including antibiotics and enzyme design.

AlphaFold’s ability to infer protein shapes from amino acid sequences has been described as a major breakthrough in medical and biological research, now offering over 200 million structure predictions that can shave months or years off lab work.

§Nearly a decade at Google DeepMind

Jumper joined Google DeepMind around 2017 and became best known for leading the AlphaFold team. During his nearly nine-year tenure at the company, he was also reported as a key member of Google’s internal tools efforts.

In an announcement on X, Jumper said he was “incredibly grateful” for his time at Google DeepMind and noted that the team had taught him “how to do great science.”

§Public departure and DeepMind’s response

On June 19, 2026, Jumper announced that he would leave Google DeepMind and join Anthropic after taking some time to recharge. Hassabis responded publicly, thanking Jumper for an “extraordinary partnership,” and saying AlphaFold “changed the world” and “showed the field what was possible with AI for science and medicine.”

§Shift toward AI startups

Jumper’s move places a Nobel Prize–winning Google DeepMind scientist inside Anthropic, one of the fastest-rising AI startups. It follows a broader pattern of prominent researchers leaving established tech firms like Google and Meta for independent AI labs preparing for public offerings.

Industry observers see the defection as both a symbolic and practical shift: cutting-edge AI work on science and safety is no longer confined to big tech incumbents, and top researchers now have multiple well-funded options competing for their expertise.
