Alphabet Inc shares fell as much as 7.2% on Monday, marking the biggest intraday decline since February following the departure of another prominent artificial intelligence leader to a competitor. According to CNBC TV18, the stock decline came after John Jumper's announcement over the weekend that he was heading to Anthropic, adding to investor concerns about the company's AI strategy and talent retention capabilities. The departure of Noam Shazeer, one of Google's most well-known researchers, to OpenAI last week has further intensified market concerns about Alphabet's ability to retain top AI talent. DA Davidson head of technology research Gil Luria noted that these departures are sparking concern that "Google is losing the war for talent at the frontier of AI," as the company has fallen off since having the state-of-the-art model for a few weeks last year.
John Jumper, Google DeepMind's Vice President and 2024 Nobel Prize winner in chemistry, is leaving the company to join Anthropic PBC. According to reports from Reuters, Jumper announced his departure on Friday, stating "After nearly nine years, I have decided to leave Google DeepMind and join Anthropic." A Google DeepMind spokesperson confirmed the departure, expressing gratitude for Jumper's contributions to advancing science and AI. Jumper serves as VP, Engineering Fellow at Google DeepMind according to his LinkedIn page and is moving to Anthropic at a time when the startup is embroiled in a high-stakes legal and regulatory battle with the U.S. government. In his X post, Jumper described Google DeepMind as a "special place" and indicated his continued interest in its future discoveries, noting that "Demis Hassabis took a real chance letting me lead the AlphaFold team just six months after finishing my PhD."
Google has struggled to sell AI coding tools to businesses, according to former employees, as reported by Business Standard. Employees and executives at DeepMind have raised concerns in recent months that the company doesn't have a clear solution for businesses seeking AI coding tools, which have become a key focus of Anthropic and OpenAI and have driven both companies' momentum in recent months. This departure follows the earlier exit of prominent researcher Noam Shazeer, who left Google for OpenAI after co-authoring a seminal paper that helped catalyze the AI boom. The latest developments highlight the fierce talent war between tech giants including Meta and Alphabet, along with upstarts such as Anthropic and OpenAI, as they race to build next-generation AI systems. Adam Crisafulli, founder of newsletter Vital Knowledge, wrote on Sunday that "OpenAI and Anthropic are increasingly the dominant frontier firms in the US and seem to be pulling away from models and coding tools from Google, Meta, and xAI," with Jumper's departure "not helping Google."
Jumper won the chemistry Nobel alongside DeepMind CEO Demis Hassabis for creating an AI model that can predict the structure of proteins called AlphaFold. As reported by Reuters, Jumper is best known as the co-creator of AlphaFold, a breakthrough AI that has predicted over 200 million protein structures, cutting years off biological and medical research. In his X post, Jumper described Google DeepMind as a "special place" and indicated his continued interest in its future discoveries. Hassabis wrote on X that "Thanks John for an extraordinary partnership and wonderful collaboration over the past 9 years. What we achieved with AlphaFold changed the world, and showed the field what was possible with AI for science and medicine, lighting the way for how AI can benefit humanity."
Jumper's departure marks the third high-profile exit from Google DeepMind in as many months, according to Bloomberg reports. Days earlier, Noam Shazeer, co-lead of Google's Gemini model and a co-author of the 2017 paper that introduced the transformer architecture, announced he was leaving for OpenAI, less than two years after Google paid a reported ₹21,000 crore to bring him back from Character.AI. Before that, David Silver, the lead researcher behind AlphaGo, AlphaZero and MuZero, left DeepMind to found his own venture, Ineffable Intelligence. The departures highlight how thinly stretched Google's research priorities have become as the company fights on multiple fronts simultaneously. Jumper's move to Anthropic extends a run of marquee additions to the startup, including Andrej Karpathy, a co-founder of OpenAI and former head of AI at Tesla, who joined in May to build a team focused on using Claude to accelerate Claude's own pretraining research. The broader impact is evident in market movements, with a Bloomberg index tracking the Magnificent Seven falling as much as 2.2% on Monday, while Amazon was down as much as 5% and Meta Platforms and Microsoft both fell more than 3%.
The departure comes days after Demis Hassabis used a fireside chat at Stanford Graduate School of Business to argue that humanity has little time left to prepare for the arrival of artificial general intelligence - defined as AI capable of matching or exceeding human performance across cognitive tasks. As reported by Livemint, Hassabis put a rough date on the milestone, stating "Maybe 2030, plus or minus a year, which is astounding to think, really." He likened its arrival to a singularity, a threshold past which there is no turning back, and urged students in both humanities and STEM fields to "lean in" to the technology rather than resist it. Hassabis warned that "Society needs to hear that because we don't have long to prepare for what that means," framing the coming years as a genuine fork in the road rather than a fixed outcome.
