AMD is acquiring World Labs. World Labs announced a definitive agreement to join AMD (announcement thread). Dr. Fei-Fei Li becomes AMD's Executive Vice President and Chief Scientist, working directly with CEO Dr. Lisa Su; co-founders Justin Johnson and Ben Mildenhall continue leading the World Labs team inside AMD. Press reports (CNBC, TechCrunch, Fortune, Reuters) put the price at about $8.2 billion, all in AMD stock, the second-largest acquisition in AMD's history. The transaction is expected to close by the end of 2026, subject to regulatory approvals. AMD shares fell about 4% on the news.
Why AMD, and why now
Li's own post, "To Seek a Newer World", lays out the reasoning. World Labs was founded at the start of 2024 by Li, Mildenhall and Johnson on the belief that "language alone isn't sufficient": the most important problems for AI, from science to robotics, "require models to reason over the structure and behavior of the physical world." The company has since built spatial-reconstruction and video models, bought robotics-simulation company SceniX (announced in July), and released Atlas on September 1, which this blog covered. Li says Atlas "essentially solved" sparse reconstruction by combining generative models with multiview geometry, and reports interest for robotics RL environments, therapy and entertainment scenes, and real-estate and construction reconstruction.
The hardware argument is Li's central one: scaling requires "getting closer to the hardware," because "without having a focused hardware effort, AI is hobbled in efficiency. And scale. And for our purposes, remains trapped in the digital world." AMD and World Labs have worked together since the earliest days: Li writes that Su "was an early investor and believer" and "a great friend," and that a deep technical partnership began last year with model training and inference optimization on AMD GPUs. The stated plan is to keep building "a world leading frontier research organization" inside AMD and to provide "the best open models and platforms for running AI end to end from hardware to software to models to the data platforms." Li describes the role as running a frontier research team "within a leading AI company."
The money and the market
World Labs raised $1 billion in February at roughly a $5 billion valuation, from investors including AMD, Nvidia, Autodesk (which put in $200 million), Emerson Collective, Fidelity and Sea; its 2024 launch round of about $230 million included Andreessen Horowitz, Intel and Nvidia. $8.2 billion is about 1.64x the February valuation in about eight months. Because it's all stock, the headline value moves with AMD's share price. AMD trades at roughly 156x earnings against a five-year median near 104x, and analysts quoted in press flag the bet as research-heavy with no near-term revenue.
On competition, press coverage frames the deal against Nvidia, which already ships open-weight world models (Cosmos) while AMD has offered only text and video models. Nvidia is itself a World Labs investor.
Two women at the center of the deal
The transaction pairs AMD's CEO with a founder-scientist: Lisa Su and Fei-Fei Li. The signing photo Li posted shows each wearing the other's company jacket. Women rarely run a major chipmaker or a frontier lab, so a deal between two who do is a genuine outlier, and Li's description of Su as a longtime friend and early backer adds a personal dimension to a very large transaction.
The second lab-to-chipmaker deal in four weeks
On September 3, Nvidia agreed to buy Hugging Face for $12.93 billion, a company that had turned down Nvidia's investment in 2025. Now AMD takes World Labs. Both deals are framed around an open ecosystem, and both bring an independent AI lab inside a chipmaker.
