Google DeepMind chiefs John Jumper, Noam Shazeer exit to Anthropic, OpenAI

What happened

Google DeepMind Vice President John Jumper announced his departure for Anthropic, and the week prior, Noam Shazeer, co-lead of the Gemini model, left for OpenAI. Alphabet's stock lost over 6% of its value—about $250 billion（約40兆円）—in the days following Jumper's announcement.

Why it matters

Alphabet's AI tools are likely the most commonly interacted with ones in the world, as its AI summaries appear with each Google Search result. Losing top talent to competitors raises the risk that a rival could launch a more useful product and endanger Alphabet's core search business. Strong AI offerings are also essential for attracting clients to Google Cloud platform.

What to watch

While the departures generated negative headlines, the article notes that Alphabet remains near the most expensive valuation level it has seen in the past decade on a cash-from-operations basis, and a broader sell-off in the AI space also contributed to the stock decline. Each departing executive will need time to get up to speed at their new roles.
