AI Chips’ New Secret Sauce Is Packaging

The WSJ finds AI chip gains now come more from packaging than from transistor shrinking, and packaging capacity has bottlenecked Nvidia's sales. TSMC converted old fabs and expanded capacity several times over, and is pulling packaging in-house from what used to be a low-margin outsourced business. That is the physical ceiling under Jensen's supply story, and it limits how many leases Nvidia can usefully stand behind.

The Clock Is Ticking for Big Tech to Make AI Pay

The market split the hyperscalers 14 percentage points apart on April 29 — Google up 7, Meta down 7 — on essentially the same balance sheet shape, which means investors stopped pricing Big Tech capex as a single risk factor. The new metric is AI revenue per depreciation dollar, and Google's 16 billion tokens per minute disclosure is the template every other CFO copies by Q3. With $430B in annual depreciation projected within five years against $372B in combined net income last year, the companies that can't show that attachment quality will face structural margin compression, not a narrative problem.

AI is confronting a supply-chain crunch

Hyperscaler capex grew 190% from 2024 to 2026; their hardware suppliers grew 45%. That gap is why every throttling notice, plan change, and Sora shutdown traces back to the same constraint. The less-discussed dimension: agentic systems need 1 CPU per GPU versus 1:12 for chatbots, which is why Intel has doubled in six months and why every agent platform deck needs a CPU supply slide.
