“Which AI researchers moved between frontier labs since 2025? For each move list the researcher, the lab they left, where they went and the month.”
The scan found 66 publicly reported moves by 58 distinct researchers across 15 labs, from February 2025 through August 2026. It is a broad, corroborated inventory of public reports — no authoritative census of all frontier-lab researchers exists — and every move here is backed by at least three pages across at least two hosts. Eight researchers moved twice.
| Researcher | Left | Joined | Month | Context | Pages | Source |

Public-report inventory of frontier-AI-lab researcher moves, Feb 2025 – Aug 2026: 66 move rows, 58 unique researchers, 37 source hosts; the most-used host backs 13 of 66 rows (19.7%). Each row required ≥3 corroborating pages across ≥2 hosts. Month is the joining/announced month per reporting, or the public-report month where start dates were unavailable. Meta Superintelligence Labs/FAIR normalized to Meta; Google AI/Research to Google DeepMind. Not a provably exhaustive census. Routes with 1 move are drawn thin but included in full.
