44 corroborated direct moves between seven frontier labs — OpenAI, Anthropic, Google DeepMind, Meta Superintelligence Labs, xAI, Safe Superintelligence and Thinking Machines Lab — from January 2025 through September 2026. Every move was reported by at least two independent web hosts; because no official roster of frontier-lab staff exists, this is a corroborated public-record list, not a provably complete one.
