2026-09-29 — AMD buys the godmother of AI

AMD agreed last night to buy World Labs, the spatial-intelligence lab Fei-Fei Li founded, for about $8.2 billion in stock — the largest AI acquisition since NVIDIA's deal for Hugging Face three weeks ago, and a straight bid to own the software layer above its chips rather than sell into someone else's. Li joins AMD as chief scientist. It broke into Monday evening, after this map's news feed had already closed for the day, which is a useful reminder that the feed is not the instrument that catches things: the generic sweep is. The same sweep also brought in SiMa.ai, a San Jose company that builds chips for AI that has to run inside a robot or a drone rather than in a data centre, priced at $1.45 billion yesterday. And the day produced one edge from two companies already on the map: Cerebras is selling Gimlet Labs 100 megawatts of its wafer-scale systems.

Marks moved

The World Labs move is worth one extra sentence. The old $5B existed only in a SiliconANGLE report, because World Labs' own February funding release stated no valuation — one of the handful of marks on this map with a number but no primary behind it. An acquisition agreement replaced it with a figure in AMD's own press release, an 8-K and the target's own blog post. Caveat: an all-stock price is not fixed, and the share count here is set by a ten-day average of AMD's stock just before closing.

New edges

• amd —owns→ worldlabs — the $8.2B all-stock acquisition, agreed 2026-09-28, close expected by end-2026 pending regulatory approval. Dashed (reported) until it closes, the same treatment nvidia —owns→ huggingface and stripe —owns→ openrouter get. AMD's existing investor edge from February stays until then.
• micron —invests_in→ sima — Micron made an undisclosed strategic investment in SiMa.ai on 2026-04-08, built around putting its LPDDR5X memory inside SiMa's Modalix chip. SiMa.ai release, verified.
• sima —fabricated_by→ tsmc and sima —builds_on→ arm — the Modalix chip is made on TSMC's N6 process and carries eight Arm Cortex-A65 cores. DCD on SiMa.ai's product release, reported.
• gimlet —builds_on→ cerebras — Cerebras will supply Gimlet Labs with 100MW of CS-4 systems over one to two years, with the first Cerebras-powered Gimlet Cloud datacentre online later this year and general availability in 2027; terms undisclosed. Cerebras release, Gimlet release, verified.

SiMa.ai is the interesting admission. Its Series C investors are all funds, which is how a dozen good companies have been kept off this map, and a pass that stopped at the latest round would have logged another miss. Micron's cheque was in a separate announcement five months earlier; the TSMC and Arm links are in the chip's own spec sheet, not in any round at all.

Still in talks

• Modal — the figure sharpened: TechCrunch reports it closing in on $750M at $15.75B, against the ~$15B Bloomberg had a week ago and the $4.65B May round the map carries. Still "closing in on", still a single unnamed source. TechCrunch
• Solidigm — Bloomberg confirmed over the weekend that SK Hynix's US flash-memory unit is weighing a US listing as soon as next year at up to $100B, where Reuters said $150B. Two top-tier outlets 50% apart is a reason to wait for a filing, not to split the difference; SK Hynix shares fell 5-6% on it. Bloomberg
• DeepSeek — the listing drifted: SCMP now frames the Shanghai debut as 2027, where Reuters in early September had the process starting this year, and the ~$7.45B round is now explicitly a pre-IPO one targeting an end-October close. Still no filing and still five post-money figures in circulation. SCMP
• Stripe / OpenRouter — 41 days since the agreement, still "in the coming weeks". Shield AI at $20B+ — 14 days, still one outlet. Manus at $4B — 12 days. UniPat at $2.5B — 19 days. Mirendil at ~$5B — 7 days. Baseten at ~$26B, OpenAI at $1.2T+, 1X/SoftBank at ~$6B: all unchanged.
• Nscale — eleven days after the S-1 and the share count and price range are still blank. The $35B is a reported target, not a filed figure.

Leads I could not verify

• Both of today's headline figures rest on search corroboration, not on a read of the page: ir.amd.com and sima.ai are both blocked by this container's egress proxy. The AMD release, the 8-K and the SiMa.ai release all appear in results with their titles and dates and several reputable outlets agree on $8.2B and $1.45B, but a human should open the two pages.
• Commure — $70M at a $7B post-money, led by General Catalyst in May, in 500-plus health systems. Clears the valuation bar easily and has no relationship to anything on this map: its investors are all funds and its one big commercial partner, HCA Healthcare, has no node here. Held off. It would be the map's second-largest healthcare AI company.
• A search summary this pass claimed NVIDIA had just acquired Hugging Face for $13B "amid OpenAI's investment bid". The map already carries that deal correctly at ~$12.9B, agreed on 2 September and closing in 2027; the OpenAI bid appears in no headline anywhere. Another reminder that the prose above a search result is not a source.
• Innovaccer at ~$3.45B: real company, but the mark is from January 2025 and no on-map edge surfaced. Not added.
