Key TakeawaysJonas Adler and Alexander Pritzel, instrumental to Google’s Gemini development, are departing for AnthropicThis follows recent exits by Nobel Prize winner John Jumper (to Anthropic) and prominent researcher Noam Shazeer (to OpenAI)Lucrative pre-IPO stock options at Anthropic and OpenAI are the main catalyst for these talent shiftsInternal resource reallocation at Google, including compute power reassignment from Shazeer’s project, contributed to departure decisionsShazeer previously earned hundreds of millions from a $2.7B Google licensing arrangement following his Character.AI ventureThe talent drain at Google’s AI division is accelerating. According to Wednesday’s Bloomberg report, Jonas Adler and Alexander Pritzel—both instrumental figures in developing Google’s Gemini AI model—are preparing to join Anthropic.Shares of Alphabet (GOOGL) declined 0.30% following the announcement. These departures arrive mere days after Nobel Prize winner John Jumper’s move to Anthropic and prominent researcher Noam Shazeer’s announcement that he’s joining OpenAI.Alphabet Inc., GOOGLAdler specialized in Google’s AI-powered coding initiatives, while Pritzel concentrated on AI system training methodologies. Both researchers were regarded as critical assets within the Gemini development team.This series of departures has spooked market participants and sparked renewed concerns about Google’s capacity to retain the specialized talent necessary for maintaining its competitive edge.A Google representative referenced statements from Google DeepMind CEO Demis Hassabis, asserting the company’s continued strength in AI talent retention. Anthropic has not provided a statement.The IPO Equity IncentiveThe financial dynamics at play are impossible to overlook. Both Anthropic and OpenAI are widely viewed as prospective IPO candidates, with potential public offerings anticipated between late 2026 and 2027.For top-tier AI researchers, transitioning from a $4 trillion publicly-traded corporation to a pre-IPO startup represents one of the most direct routes to substantial wealth creation. While restricted stock units at Google provide strong compensation, the potential returns are largely predictable. Conversely, pre-IPO equity in a rapidly expanding AI venture presents an entirely different risk-reward profile.Shazeer’s professional trajectory perfectly demonstrates this dynamic. After departing Google in 2021 to launch Character.AI, Google subsequently paid approximately $2.7 billion via a licensing agreement that facilitated his return. According to the Wall Street Journal, he netted hundreds of millions from his ownership stake in that deal.His latest move takes him to OpenAI, which recently submitted a confidential IPO filing. Should he have negotiated new equity as part of this transition, he’s positioned for another potentially massive payday.Internal Resource Decisions Created Additional TensionFinancial considerations weren’t the sole factor. In at least one instance, internal strategic decisions at Google seem to have intensified frustrations.Just before Shazeer revealed his OpenAI transition, computational resources allocated to one of his projects were redirected to a London-based Google DeepMind team. The reallocation was officially framed as an initiative to enhance collaboration and optimize pre-training operations—the foundational stage of AI development where models absorb information from massive datasets.However, for a researcher whose work depends heavily on computational access, such a resource reduction carries significant implications. This detail illustrates why monetary incentives alone don’t fully explain the exodus.Google spent much of the current AI race playing catch-up before gaining traction in late 2025 with improved models and proprietary chip technology. The consecutive departures of Jumper, Shazeer, Adler, and Pritzel now cast doubt on whether that momentum can be sustained.Adler, Pritzel, Jumper, and Shazeer have not responded to media inquiries.The post Alphabet (GOOGL) Stock Dips as Google Faces Brain Drain to Anthropic appeared first on Blockonomi.
