Alphabet lost $269 billion in market capitalization following the departure of four senior Google DeepMind scientists to rival AI companies.
The exodus included Nobel laureate John Jumper, who joined Anthropic, and Transformer co-author Noam Shazeer, who moved to OpenAI.
The high-profile losses rattled investors, contributing to a steep decline in Alphabet’s stock in one of its most significant single valuation drops.
The departures highlight the intense competition for top AI talent, where leading researchers have become a decisive asset.
