Nobel Laureate John Jumper Is Leaving DeepMind for Anthropic
John Jumper — the DeepMind VP and 2024 Chemistry Nobel laureate who led AlphaFold — is leaving Google DeepMind for Anthropic after nearly nine years, deepening the AI talent war.
TL;DR — On June 19, 2026, John Jumper — the Google DeepMind VP and 2024 Nobel laureate who led the AlphaFold team — announced he is leaving DeepMind for rival Anthropic after nearly nine years, one of the highest-profile defections yet in the AI talent war.
Few scientists carry the weight John Jumper does. He shared the 2024 Nobel Prize in Chemistry for AlphaFold, the system that cracked protein-structure prediction. So when he says he's switching labs, the field listens — and on June 19, 2026, he said exactly that.
What happened
Jumper announced on his verified X account that "after nearly 9 years, I have decided to leave Google DeepMind and join Anthropic (after taking some time to recharge)," a move Bloomberg and CNBC confirmed via an Anthropic spokesperson. At DeepMind he was a Vice President and led the AlphaFold team — which he was tapped to run just six months after finishing his PhD.
One notable gap: neither side has disclosed what role he'll take at Anthropic. Reporting speculates it fits Anthropic's growing push into life sciences, but that isn't confirmed.
Why it matters: the talent war is intensifying
| Move | From → To | Announced |
|---|---|---|
| John Jumper — Nobel '24, AlphaFold lead | Google DeepMind → Anthropic | Jun 19, 2026 |
| Noam Shazeer — "Attention Is All You Need", Gemini co-lead | Google → OpenAI | days earlier, Jun 2026 |
Jumper's exit lands just days after Noam Shazeer — a Gemini co-lead and co-author of the foundational "Attention Is All You Need" paper — left Google for OpenAI, per TechCrunch. Two marquee names leaving DeepMind/Google in a week reads as a talent drain at exactly the moment the labs are racing hardest.
The stakes
AlphaFold's open database now offers over 200 million protein-structure predictions and has been used by more than 2 million scientists across 190+ countries. Anthropic, meanwhile, raised a $65 billion Series H at a $965 billion post-money valuation in May 2026 — it can afford to hire almost anyone. As DeepMind CEO Demis Hassabis put it: "What we achieved with AlphaFold changed the world, and showed the field what was possible with AI for science and medicine."
FAQ
Is John Jumper really leaving DeepMind for Anthropic?
Yes. He announced it on his verified X account on June 19, 2026, and Anthropic confirmed the hire to multiple outlets. He spent nearly nine years at Google DeepMind.
What did he do at DeepMind?
He was a Vice President and led the AlphaFold team, the protein-structure-prediction system that won him a share of the 2024 Nobel Prize in Chemistry.
What will he do at Anthropic?
Not disclosed. Neither Anthropic nor Jumper has said what his role will be; observers speculate it relates to Anthropic's life-sciences ambitions.
Why is this a big deal?
It's a rare top-tier defection — a Nobel laureate moving between leading labs — and it follows Noam Shazeer's departure from Google for OpenAI days earlier, signaling an intensifying AI talent war.
