Google Stock Drops 5% As Top AI Researchers Quit

Alphabet stock fell as much as 5 percent on Wednesday after four of Google's most cited researchers quit in a single day. The sudden exits included chief scientist Jeff Dean, who is leaving after a 27 year run to launch a new scientific startup called Discovery Loop. The wave of departures wiped out nearly $190 billion in market value during a turbulent trading session.

Investors reacted quickly because leadership changes at top tech firms often signal shifts in the broader technology sector. Demis Hassabis stepped away from his day to day role at Google DeepMind to become chairman, leaving Koray Kavukcuoglu to take over the Gemini development team. Despite strong quarterly earnings and growing cloud revenue, markets remain sensitive to high level talent losses in the artificial intelligence race.

Traders and industry watchers will now look toward the upcoming release of Gemini 4 to gauge how well the tech giant operates without some of its founding minds. As competition heats up across the sector, maintaining momentum on core AI projects remains critical. Keep an eye on how upcoming product launches perform against rival models in the coming months.
