Nobel Laureate John Jumper Leaves DeepMind for Rival Anthropic

The single sharpest fact in one or two punchy sentences. John Jumper, a Nobel laureate, is leaving Google DeepMind for Anthropic after nearly 9 years with the company.

John Jumper, a renowned chemist and computer scientist, announced on X that he’s making the leap to Anthropic after serving as the lead of the AlphaFold team at Google DeepMind. Jumper, who shared the Nobel Prize in chemistry in 2025, made the decision to leave DeepMind after nearly a decade with the company.

Jumper wrote on X that DeepMind CEO Demis Hassabis “took a real chance letting me lead the AlphaFold team just six months after finishing my PhD, and the entire GDM team taught me so much about how to do great science.” In the post, Jumper expressed gratitude for the opportunities he had at DeepMind, including the chance to work with the talented team and make significant advancements in the field of protein folding.

Anthropic is a relatively new player in the AI research scene, having been founded in 2021 by Dario Amodei, the former CTO of Sam Altman's new startup, and Danny Hernandez, a former member of the AlphaFold team. The company has quickly gained a reputation for its innovative approaches to AI research and its commitment to open-source development.

The move raises questions about the competitive landscape of the AI research sector and the role of the biggest players in the field. With Jumper's departure, DeepMind has lost one of its top researchers and a key figure in the field of protein folding. Meanwhile, Anthropic has gained a high-profile recruit and a significant boost to its credibility.

DeepMind, founded in 2011 by Demis Hassabis, Shane Legg, and Mustafa Suleyman, has been at the forefront of AI research for several years, with a focus on developing cutting-edge algorithms and applications for the field. Hassabis, a renowned computer game designer and AI researcher, has been a key figure in shaping the company's research agenda and has played a significant role in its success.

In a statement, Hassabis expressed his gratitude for Jumper's contributions to DeepMind and wished him the best in his new role. Amodei, the CEO of Anthropic, also praised Jumper's talents and expressed his excitement about the potential of their collaboration.

The departure of Jumper highlights the high stakes and intense competition in the AI research sector. With the field growing rapidly and new companies emerging, researchers and engineers are increasingly looking for opportunities to join top teams and make significant contributions to the field.
