Amodei's concern is not a direct public quote but was reported by Axios via a source familiar with the matter . It fits a broader problem across frontier AI laboratories: extraordinary pay can buy talent, but it cannot guarantee loyalty, cultural alignment, or long-term commitment to a mission .
Amodei has laid out several specific concerns about the direction of Anthropic's growth:
Amodei's worry is not happening in isolation. Across the industry, top researchers are moving between labs at an unprecedented pace, driven by compensation, compute access, influence, and ideology.
Founded by former OpenAI CTO Mira Murati, Thinking Machines Lab raised a $2 billion seed round at a $12 billion valuation in 2025. But nearly a third of its 42-person founding team — 13 people, including 3 of its 6 co-founders — have left since launch . Cofounders Barret Zoph and Luke Metz returned to OpenAI in January 2026; two more founders joined Meta in February 2026 . By April 2026, at least seven former Thinking Machines employees were working at Meta .
The most dramatic event came in June 2026. On June 18, Noam Shazeer — Gemini co-lead and co-author of the 2017 "Attention Is All You Need" paper that underpins all frontier AI models — left Google for OpenAI . Forty-eight hours later, John Jumper, the 2024 Nobel laureate who co-created AlphaFold, announced he was leaving Google DeepMind for Anthropic . Alphabet's stock fell 6.8% on Monday, June 22, as the market opened, wiping roughly $270 billion in market value — its worst day in over a year . Researchers Jonas Adler and Alexander Pritzel also left Google for Anthropic shortly after .
Meta, under Mark Zuckerberg, has been the most aggressive poacher. Packages reportedly reach up to $300 million over four years for top talent . Meta's own retention rate (64%) trails Anthropic's, though a steady stream of Thinking Machines and Google defectors has strengthened its bench .
The term has become the defining framework for AI talent strategy . Researchers now weigh four key dimensions when switching jobs:
Amodei's original model — that below-market pay would self-select true believers — worked when Anthropic was small and unknown. Now, with a ~$965 billion valuation and an IPO reportedly on the table, the company's compensation has risen past every competitor's, making it indistinguishable on price from the labs it was meant to be an ethical alternative to .
Safety researchers inside Anthropic have also quit publicly, warning that the "world is in peril" and that safety teams face constant pressure to deprioritize their work . Anthropic was founded with the explicit goal of creating safe AI, and Amodei himself has said the company faces "an incredible amount of commercial pressure" that makes it harder to maintain safety commitments .
The missionaries-and-mercenaries problem, in short, is no longer a question of which lab you join — it now exists inside Anthropic itself . As one observer noted: "You cannot offer engineers up to roughly $1.3 million a year and then be surprised when some applicants notice the money" .
