AMD signed an $8.2 billion deal and cannot say what it costs in shares
The World Labs merger agreement fixes the price and floats the share count on AMD's own falling stock. The seller list includes Nvidia, AMD itself, and, by Fei-Fei Li's account, AMD's own CEO.

Two years after founding World Labs, Fei-Fei Li is selling it to her own GPU supplier. She becomes AMD's executive vice president and chief scientist, reporting to Lisa Su, and announced the move with a line of Tennyson, "to seek a newer world" 12. The currency is AMD shareholders' stock, and the filing that spends it concedes it cannot yet be counted 3.
The price is fixed; the count is not
Signed September 26 and filed September 28, the merger agreement pays roughly $8.2 billion in AMD common stock for every equity interest in World Labs, and the number of shares "is not known": it will be set by AMD's volume-weighted average price over the ten trading days ending two days before closing 3, which the company expects around year end, subject to regulatory approvals 24. It is AMD's biggest buy since Xilinx and its second-largest ever 5.

Data
| Value | |
|---|---|
| Xilinx (2020) | $35B |
| World Labs (2026) | $8.2B |
| ATI (2006) | $5.4B |
| ZT Systems (2024) | $4.9B |
| Pensando (2022) | $1.9B |
The valve points the other way
Xilinx, AMD's last giant stock deal, was an all-stock swap that rode AMD's rise from $35 billion at signing to near $50 billion at close 65. World Labs' terms point the valve the other way. The dollars are fixed, so every decline in AMD's price, including the 3.6 percent it shed on announcement day while Nvidia rose 1.7 percent 4, prints more shares to deliver the same $8.2 billion, and the stock goes out under a private-placement exemption with no prospectus behind it 3.
Read the seller list
Seven months before signing, AMD joined World Labs' $1 billion round at a valuation reported near $5 billion, with PitchBook logging $5.4 billion post-money, alongside Nvidia, Autodesk, Emerson Collective, Fidelity and Sea 72. The price now sits 52 to 64 percent above marks AMD helped underwrite 72. Because AMD is buying all of the equity interests, its own February stake is inside the $8.2 billion 3, and Nvidia exits a seven-month-old position into liquid AMD stock. Li names Su an early investor in World Labs personally; no filing or report prices that stake, and AMD's own investment amount was never disclosed 17.

The strategy is real, the arithmetic unchanged
Su's stated logic is that model builders show the hardware team what comes next 2, and Nvidia plays the same game, paying $12.9 billion for Hugging Face this month 8. AMD has already granted OpenAI an option on 160 million shares at a cent each, tied to a six-gigawatt order 5. The chip vendors now own pieces of the demand they sell into, and robotics, as one analyst put it, "still hasn't had its ChatGPT moment": the bet is long-dated 9.
Two trading days before close
Watch AMD's average price into a year-end close, the share count it fixes two trading days beforehand, and any disclosure of Su's stake. The price is fixed, the count floats, and the other side of that trade is everyone already holding AMD 3.
