Alphabet Shares Slide 6% After Top AI Researchers Depart for Anthropic, OpenAI
GOOG•Alphabet’s shares plunged 6% on June 22 after Nobel laureate John Jumper and Gemini co-lead Noam Shazeer exited for Anthropic and OpenAI, erasing roughly $250 billion in market capitalization. The stock now trades 14.4% below its mid-May high as investor concerns grow over talent retention.
1. Steep Share Decline
Alphabet’s shares closed June 22 down 4.99%, trading 14.4% below its mid-May peak after a year-to-date rally of nearly 30%. This marked the steepest one-day drop in over a year, signaling renewed volatility in the stock.
2. High-Profile AI Talent Exodus
John Jumper, vice president of DeepMind and 2024 Nobel laureate, announced his move to Anthropic after nearly nine years leading the AlphaFold2 team. Noam Shazeer, co-lead of Project Gemini and co-author of the 2017 Transformer paper, left for OpenAI less than two years after rejoining via a $2.7 billion acquisition.
3. Investor Sentiment and Market Outlook
The back-to-back exits wiped out roughly $250 billion in market value and heightened fears that Alphabet may struggle to retain elite AI engineers. Market participants are divided on whether the selloff opens a buying window or signals deeper execution risks in its AI strategy.
