AMD Agrees to Buy Fei-Fei Li's World Labs for $8.2 Billion in Stock
AMD will acquire World Labs, the spatial-intelligence lab led by ImageNet pioneer Fei-Fei Li, in an all-stock deal worth about $8.2 billion. Li becomes AMD's Chief Scientist, reporting to Lisa Su.
AMD has signed a definitive agreement to acquire World Labs, the AI model and research lab led by Dr. Fei-Fei Li. The all-stock deal, announced on Monday, September 28, 2026, is valued at approximately $8.2 billion.
It is an unusual move: a GPU maker buying a frontier model lab outright. With it, AMD gets in-house research on world models - AI that generates and simulates 3D environments - just as those models become central to robotics and autonomous machines, a market where Nvidia has been building its own stack.
What AMD announced
According to AMD's press release, the company will pay for World Labs entirely in stock, in a transaction valued at approximately $8.2 billion. The deal is expected to close by the end of 2026, subject to regulatory approvals and customary closing conditions. Until then, it is an agreement to acquire, not a completed purchase.
TechCrunch notes that this would be AMD's second-largest acquisition on record, behind the roughly $50 billion Xilinx deal completed in 2022. Fortune reports that World Labs had raised roughly $1 billion in total before the deal. Neither company disclosed World Labs' most recent valuation.
Deal at a glance
Buyer: AMD. Target: World Labs. Price: approximately $8.2 billion, all stock. Expected close: by the end of 2026, pending regulatory approval. Fei-Fei Li joins AMD as Executive Vice President and Chief Scientist.
What World Labs builds
World Labs was founded in 2024 around what Li calls spatial intelligence. Per AMD, its models generate, reconstruct and simulate interactive 3D environments from text, image and video inputs, and the company also works on robotic learning and simulation technology.
Its first product, Marble, is a tool for creating entertainment experiences and simulated environments used to train robots. World Labs' announcement also names Marble Labs (a research platform), the Atlas model, the Spark JavaScript library and a developer API. In her own post, Li describes Atlas as an omni model for view prediction and mentions that World Labs acquired SceniX for robotics simulation.
Fei-Fei Li's new role at AMD
Li, a Stanford computer science professor best known for building the ImageNet dataset and the competitions it inspired, joins AMD as Executive Vice President and Chief Scientist, reporting directly to CEO Dr. Lisa Su. World Labs co-founders Justin Johnson and Ben Mildenhall will work with Li and continue to lead the World Labs team inside AMD as a frontier research organization.
The two companies were not strangers. They began a deep technical partnership in 2025, starting with model training and inference optimization on AMD GPUs, and Li appeared in AMD's CES 2026 presentation. Li also describes Su as an early investor in and believer in World Labs.
Explaining the decision, Li wrote: "Without having a focused hardware effort, AI is hobbled in efficiency." World Labs' blog put it in similar terms: "To accelerate into this future requires scaling our efforts, scaling our reach, and getting closer to the hardware."
Why a chipmaker wants a world-model lab
Lisa Su framed the deal around understanding the workloads AMD's chips will run: "Building the compute platforms for the next generation of AI requires a deep understanding of how models are evolving." Li's line in the press release mirrors it: "Advancing the next generation of AI technology requires close collaboration across model research, systems and compute."
World models matter because robots, autonomous vehicles, industrial machines and humanoids need far more training data than the real world can easily supply. Simulated environments fill that gap with synthetic data. TechCrunch points out that the purchase positions AMD against Nvidia's world-model ecosystem, including Cosmos.
Li summed up the bet to Fortune: "The universe isn't made up of words, it's made of real things."
Market reaction
Early reports on how investors took the news differ. Fortune said AMD shares were roughly flat in after-hours trading on Monday, while a Stocktwits report carried by TradingView said AMD fell about 4% on Monday as Nvidia rose about 1.8%. The same Stocktwits report puts World Labs' team at about 70 specialists.
What we don't know yet
- Whether regulators will clear the deal on the expected timeline, by the end of 2026.
- What happens to Marble, the World Labs API and existing customers once the lab is part of AMD. Neither company has said.
- World Labs' valuation before the deal, which was not disclosed.
