Annual rosters
2026
The biggest AI hires of 2026 (so far)
Anthropic spent the first five months of 2026 building an infrastructure bench one hire a month, while OpenAI lost three of its five senior operating executives, Google surrendered a Gemini co-architect and then four senior scientists in a single afternoon, and Apple handed its next chapter to an engineer promoted from hardware rather than an outside AI star. Twenty verified moves anchor this roster, ranked by strategic weight: scale of the team that moved, seniority of the role, the rationale a company stated or analysts inferred, compensation signal where disclosed, competitive timing, and control over a scarce resource, whether that resource is compute, research talent, or institutional trust. Infrastructure and continuity dominate the pattern that emerges: Anthropic recruited more procurement, security, and real-estate leads than headline researchers, and the year's single largest departure event, Jeff Dean's exit from Google to found Discovery Loop, took three more senior scientists with it in one afternoon.
2025
The biggest AI hires of 2025
Two years of AI hiring compressed into one roster: Meta bought its way into frontier research with a $14.3 billion stake in Scale AI and a wave of nine-figure offers to researchers at OpenAI and Apple, OpenAI rebuilt its entire C-suite around consumer operators after Mira Murati, John Schulman, and Ilya Sutskever walked out in 2024, and Google and Microsoft answered with license-and-hire structures that pulled Windsurf, Character.AI, and Inflection AI's leaders in-house without a formal acquisition. Twenty-six verified moves anchor this roster, ranked by strategic weight: the capital behind the deal, the seniority of the role, and how directly the move shifted control over frontier research capacity. Founder-scientist labs defined the era's other current, as Sutskever, Gross, and Levy left OpenAI and Apple to build Safe Superintelligence, and Murati drew her own OpenAI alumni into Thinking Machines Lab, only for Meta to reclaim five of its founding engineers within the year.
