Alphabet reshuffles DeepMind leadership as GOOG stock slides on AI shake-up

Alphabet’s DeepMind is undergoing a leadership shake-up: Demis Hassabis will become DeepMind chair and Alphabet chief scientist; Koray Kavukcuoglu will become DeepMind senior vice president; Jeff Dean and Sanjay Ghemawat are leaving to form Discovery Loop. The moves come as Alphabet reports strong AI-driven growth (latest quarter revenue up 82% to $24.77B) but Gemini 3.5 Pro delays and higher capex guidance (to about $195–$205B) weigh on sentiment, with GOOG stock falling roughly 4% on the news.
