Open-source reporting across 10 news hosts identified 89 direct lab-to-lab moves by 84 researchers from January 2025 through September 2026 — the latest reported move found by the 2026-10-31 research cutoff. This is a best-effort public-record census, not a complete registry; a researcher appears more than once when they moved more than once.
Ribbon width is the number of corrected move records on each route. Hover a lab or ribbon for the researchers behind it.

Method: best-effort census of publicly reported researcher moves between frontier AI labs, January 2025 – September 2026, compiled from 10 news hosts (research cutoff 2026-10-31); 89 move records across 84 researchers, each row carrying its source link and the count of independent hosts supporting it. Two ambiguous-origin records were corrected against the evidence: John Schulman’s immediate prior lab was Anthropic, so the OpenAI → Thinking Machines row for him was dropped and the Anthropic → Thinking Machines row kept; Huiwen Chang joined Meta from Google Research, so the duplicate OpenAI-origin row was dropped. Month is when the move began or was publicly announced, as reporting disclosed. Private or unreported moves cannot be observed; single-host rows are marked lower confidence rather than hidden.
