AMD Bets $8.2 Billion in Stock on Fei-Fei Li's World Labs

Advanced Micro Devices agreed Monday to acquire World Labs, the artificial-intelligence startup led by Fei-Fei Li, in an all-stock deal worth about $8.2 billion — the chipmaker's biggest bet yet that the next era of AI will be won by whoever understands the models, not just whoever fabricates the silicon.

SANTA CLARA, Calif. — AMD said Monday it has entered into a definitive agreement to acquire World Labs, an AI model and research lab led by Li, in a transaction valued at approximately $8.2 billion and paid entirely in AMD shares. The deal is expected to close by the end of 2026, subject to regulatory approvals and other customary closing conditions.

As part of the transaction, Li will join AMD as executive vice president and chief scientist, reporting directly to chair and chief executive Lisa Su. The World Labs team, headquartered in San Francisco, will continue to focus on advancing AI model research after the close.

The price buys AMD something it cannot fabricate on its own: a front-row seat to the workloads its future chips must run. World Labs develops spatial-intelligence models — systems that generate, reconstruct and simulate interactive 3D environments from text, image and video inputs — alongside technology for robotic learning and simulation. As AI expands into reasoning, robotics, simulation and physical AI, the demands on compute infrastructure become more diverse, AMD said, and deeper insight into how workloads are evolving is what shapes a chipmaker's technology roadmaps.

The terms: $8.2 billion, all stock, closing by year-end

The structure matters as much as the price. An all-stock deal means AMD's existing shareholders fund the acquisition through dilution — more shares outstanding against future earnings — rather than cash from the balance sheet. At roughly $8.2 billion, AMD is paying more than eight times the valuation implied by the $1 billion funding round World Labs raised earlier this year, which Reuters reported included an investment from AMD itself.

The agreement is definitive, but it is not a closed deal. AMD said it expects the transaction to close by the end of 2026, subject to regulatory approvals and customary closing conditions. The announcement did not say which jurisdictions' regulators will review the transaction — a real variable, given that large semiconductor deals have a long history of running into trouble in antitrust review.

Fei-Fei Li, on AMD's org chart

The personnel terms are the tell. Li — the Stanford computer science professor whose ImageNet work made her one of the most cited figures in modern AI, described by MarketWatch as the 'godmother of artificial intelligence' — founded World Labs in 2024 to build models with a more grounded understanding of the physical world. Her new title, chief scientist, puts research leadership inside AMD's top ranks rather than in an acquired subsidiary, and she will report directly to Su.

The two sides are not strangers. World Labs and AMD began a deep technical partnership last year, working on model training and inference optimization on AMD graphics processors, and Li appeared as a guest at AMD's CES presentation earlier this year. AMD Ventures invested in World Labs' latest financing round in March.

Why a chipmaker wants a model lab

"Building the compute platforms for the next generation of AI requires a deep understanding of how models are evolving," Su said in the announcement. "Fei-Fei and the World Labs team bring exceptional research leadership and model expertise. Together, we can use that insight to develop the hardware, software and systems that will power the next generation of AI and strengthen the open AI ecosystem."

Li framed the combination as a scaling move: "Advancing the next generation of AI technology requires close collaboration across model research, systems and compute," she said. "Joining AMD will give our team the resources and engineering depth to accelerate our research and help define the infrastructure needed for the next era of AI."

World Labs' work sits at the edge of the industry's current fixation: physical AI. Its first product, Marble, lets users create interactive 3D worlds from a prompt, and a related model, Atlas, predicts how a scene looks from different camera angles — the kind of simulation technology aimed at training robots and generating synthetic data for autonomous systems, where real-world training data is scarce.

The market's shrug — and the dilution question

Investors did not cheer. AMD shares fell 3.6% in Monday's regular session and added just 0.4% in after-hours trading, according to MarketWatch. The muted reaction is legible: a rich implied valuation for a research lab, paid in new shares, with the payoff resting entirely on future roadmaps.

The contrast with the day's other chip news was hard to miss. Nvidia added $150 billion to its buyback program on Monday — taking shares off the market while AMD moved to create more of them, a reminder that the two rivals are funding their AI ambitions from opposite sides of the capital structure.

The open-ecosystem bet

AMD framed the acquisition as advancing its strategy to deliver AI infrastructure for an open ecosystem — open models, whose code and training data can be modified by any developer, gaining traction as cheaper alternatives to closed-source systems. The competitive subtext is clear enough: the deal gives AMD a research asset and a direct line into the frontier model research that determines what AI hardware gets bought.
