68 corroborated researcher moves since 2025 — Meta's June–July 2025 raid is the biggest single wave

Asked:

“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.”

A public-web scan found 68 independently corroborated researcher moves between frontier AI labs from January 2025 through October 26, 2026, across 13 labs and drawn from 31 source hosts. Each move was kept only when at least two independent hosts reported it; the month is the reported announcement or start month. This is a best-effort public record, not a complete census — unannounced moves are absent.

Where researchers left, and where they went

Ribbon width = number of corroborated moves. Hover a ribbon or lab for the researchers behind it. Colour marks the departed lab. Period buttons filter the flow; the table below filters with it.

Meta hired 29 of the 68 movers, 19 of them in June–July 2025 alone — 13 from OpenAI, 6 from Google DeepMind — for its superintelligence push. aiwiki.ai

Thinking Machines Lab absorbed 7 senior people in February 2025, mostly from OpenAI — then lost 5 back to OpenAI in January 2026. the-ledger.net

June 2026 brought a Google DeepMind outflow: several departures to Anthropic and OpenAI in a single month. bimcmedia.com

John Schulman appears twice in February 2025 — public reporting on his origin lab (OpenAI vs Anthropic) is inconsistent, so both records are kept and flagged. winbuzzer.com

Every corroborated move, chronological

Method: 68 researcher-move records between frontier AI labs, January 2025 – October 26, 2026, assembled from a public-web scan of 31 source hosts; a move was retained only when at least two independent hosts corroborated it, and no single URL supports more than 7 rows. Month is the most-supported announcement/start month. "Hosts" counts independent corroborating hosts. One person can appear more than once for multiple moves; John Schulman's February 2025 origin is reported inconsistently and both records are flagged. Private or unreported moves are absent; this is not a census.
