AMD agrees to acquire Fei-Fei Li's World Labs in an all-stock deal valued at about $8.2bn

AMD has "entered into a definitive agreement to acquire World Labs", the AI model and research lab led by Fei-Fei Li, the chipmaker said in a press release dated 28 September 2026 (issued at 4:05pm EDT, 9:05pm UK time). AMD says the "all-stock transaction is valued at approximately $8.2 billion".

The deal, in AMD's words

• Price and structure. AMD's release calls it an "all-stock transaction" valued at "approximately $8.2 billion". AMD's filing with the US Securities and Exchange Commission (a Form 8-K signed on 28 September) says the merger agreement was signed on 26 September and puts the "total purchase price of approximately $8.2 billion to be paid in shares of the Company's common stock", "subject to customary adjustments".
• How many shares. The filing says the number of shares "is not known" yet and will be calculated from AMD's volume-weighted average share price over a ten-trading-day period ending two trading days before closing.
• Timing. The deal "is expected to close by the end of 2026, subject to regulatory approvals and other customary closing conditions", AMD says. It has not closed.
• People. After closing, AMD says, "the World Labs team will continue to focus on advancing AI model research", and Li "will join AMD as executive vice president and chief scientist, reporting to Dr. Lisa Su". World Labs' own announcement adds that co-founders Justin Johnson and Ben Mildenhall "will work with Fei-Fei to continue leading the World Labs team".

Neither announcement gives a headcount; Fortune reports that the companies "did not provide specific figures for the number of employees".

What World Labs does

AMD describes World Labs as a San Francisco company that "develops spatial-intelligence models that generate, reconstruct and simulate interactive 3D environments from text, image and video inputs, as well as technology for robotic learning and simulation." Its products include Marble, a 3D world-building tool, and World Labs' Atlas model — a bet on "spatial intelligence" that was entering early access with select partners when we covered it.

Why the two companies say they are doing it

AMD's stated rationale is about its own roadmap. "Building the compute platforms for the next generation of AI requires a deep understanding of how models are evolving," Lisa Su, AMD's chair and CEO, said in the release. AMD says World Labs' expertise "will give AMD deeper insight into how workloads are evolving and help shape its future technology roadmaps", and that the deal "advances AMD's strategy to deliver AI infrastructure for an open ecosystem."

Li framed it in a post on her Substack as a matter of scale and hardware: she wrote that accelerating the lab's work "requires scaling our efforts, widening our reach, and getting closer to the hardware." She added: "Without having a focused hardware effort, AI is hobbled in efficiency. And scale. And for our purposes, remains trapped in the digital world."

An existing relationship

The deal follows an existing tie. World Labs says it "began a deep technical partnership with AMD last year, starting with model training and inference optimization on AMD GPUs." Li wrote that Su "was an early investor". When World Labs announced $1 billion in new funding on 18 February 2026, it listed its investors as including AMD, Autodesk, Emerson Collective, Fidelity, Nvidia and Sea, "among others". Neither company has said what valuation that round implied, and we have not found a figure in the sources we read.

Market reaction

Fortune reported on Monday evening (US time) that "Shares of AMD were roughly flat in after-hours trading on Monday." US markets had not opened for Tuesday's session when we published.

How others read it

TechCrunch wrote that the acquisition "is likely to help AMD compete with long-standing rival Nvidia", noting that Nvidia already offers open-weight world models such as Cosmos. Fortune described the deal as helping AMD "better compete with archrival Nvidia", which it said is also expanding into physical AI. CNBC reported that AMD "plans to keep World Labs separate from its chipmaking business until the transaction closes".

Why it matters

On our reading, this is a chipmaker buying a model lab for the reason AMD states in its release: to understand the workloads its hardware will have to run. What AMD will do with World Labs' products after closing is not set out beyond general commitments: World Labs says the combined companies are committed to "building out an end-to-end open AI ecosystem spanning hardware, software, platforms, and widely accessible open models", and Li wrote that they are "committed to providing the best open models and platforms". The deal still needs regulatory approval, and AMD's own release describes its expected benefits and timing as forward-looking statements.
