Alphabet Shares Drop After Second AI Star Departs for a Rival

shares fell as much as 7.2% on Monday after the company announced that John Jumper, a vice president at Google DeepMind, is leaving to join rival AI lab Anthropic. The two exits mark a significant loss of top-tier AI research talent from Alphabet's flagship AI division.

The market reaction reflects investor concern about Alphabet's ability to retain key personnel amid intensifying competition for AI researchers.

The moves underscore the fierce talent war in the AI industry, with major labs like OpenAI and Anthropic aggressively poaching from each other. Analysts noted that while Alphabet remains a formidable player, the loss of high-profile researchers could slow its progress in certain areas.
