The expanded search finds 35 candidate direct moves between frontier AI labs — OpenAI, Anthropic, Google DeepMind, Meta AI / Superintelligence Labs, Microsoft AI, Mistral AI, Thinking Machines Lab and xAI — from January 2025 through the scan date of 28 August 2026: 25 more pathways than the earlier 10-person documented shortlist. 32 moves resolve to a month; three (Allan Jabri, Lu Liu, Ross Nordeen) are supported but undated. Confidence is labelled per row: 8 corroborated reported moves, 10 inferred from public occupation histories, and 17 single-source reports kept visible at lower confidence — inference is not employer-confirmed fact.
