Six days after Google announced that Sir Demis Hassabis was stepping down as CEO of Google DeepMind, the story that has stuck is not the one Google wrote. It is the one circulating through investor group chats and London AI circles: that Hassabis wanted out entirely, at the same moment Jeff Dean walked, and was talked into a chairmanship instead. The claim originates with the Pathfounders newsletter, which reported on August 8 that industry sources believe Hassabis intended to exit alongside Dean, and that Google management feared the twin departure would gut the share price.Google has not addressed the report. What Hassabis has done, three days ago, is post a note on LinkedIn that reads like a man closing a chapter on his own terms. It restates the AGI framing from his internal memo almost word for word, points readers to the company blog, and says nothing about why the timing landed on a Wednesday evening in London, minutes before Dean’s announcement broke.
What Google actually announced, and why the timing raised eyebrows
The official version is straightforward enough. Hassabis becomes Chair of Google DeepMind and Chief Scientist of Alphabet, keeping his role at Isomorphic Labs. Koray Kavukcuoglu, DeepMind’s CTO for years and now based in Mountain View, takes over day-to-day operations as SVP, reporting directly to Sundar Pichai. Notably, Google did not appoint a new DeepMind CEO at all. Minutes after the memo landed, Dean, employee number 30 and a 27-year veteran, said he was leaving with Sanjay Ghemawat, Oriol Vinyals and Quoc Le to start Discovery Loop, a public benefit corporation Google will fund as founding investor and cloud partner. Alphabet stock fell around 5 per cent.
Demis Hassabis’ full LinkedIn post amid exit rumours
“I’ve been working towards AGI my whole life and I believe it is now close at hand. It’s critical that as a society we get the next steps right to ensure this profound technology benefits all of humanity and ushers in an incredible new age of discovery and wonder.As we enter this pivotal moment, I’ve decided to step into a new role as Chair of Google DeepMind and Chief Scientist of Alphabet. This will allow me to focus on long-term AGI strategy and accelerating scientific breakthroughs, including leaning even further into my work at Isomorphic Labs where we are making extremely rapid and promising progress on our mission to cure disease.We’ve achieved so many extraordinary things at Google DeepMind so far and I’m very excited for this next chapter under the leadership of koray kavukcuoglu. I look forward to continuing to work with him, Sundar and the executive team.”
Deepmind’s London-to-Mountain View shift nobody at Google will confirm
The Financial Times reported on August 6 that the reorganisation moves control of Google’s AI effort from London back to Silicon Valley, and cements the returning influence of co-founder Sergey Brin, who now sits near Kavukcuoglu’s desk. The FT also reported that senior executives had grown frustrated with what they saw as Hassabis’s lighter focus on commercial demands, and that his decision to release AlphaFold freely became a point of internal friction. A person close to the company disputed that any tension existed. A Google spokesperson separately denied that power was moving west, noting Hassabis and much of the leadership remain in London at the new Platform 37 offices.
The Gemini delays sitting underneath all of it
Fortune’s reporting on August 10, based on three current and one former DeepMind employee, fills in the harder texture. Gemini 3.5 Pro, unveiled at I/O in May with a promise to ship the following month, has missed three deadlines. Engineers blame a decision last summer to deprioritise coding while Anthropic and OpenAI ran ahead on agentic tools. Staff described 60-hour weeks, burnout, and a leadership vacuum in which Brin was visible on the floor and Hassabis was not. June alone took Gemini co-lead Noam Shazeer to OpenAI and AlphaFold co-inventor John Jumper to Anthropic. A union bid launched in May over the Pentagon contract is still unresolved.Pathfounders ended its item with a prediction rather than a source: Hassabis will have left Google within a year.
