Writes Second Order by TKN — a plain-English map of AI infrastructure and semiconductors for non-specialist investors. Focus: who gets paid, where money sticks, and which step is stuck. Not investment advice.

TSMC is paying NT$38.8 billion for AUO's Taichung display plant, clean rooms included. It paid the top appraisal, and about 67% more per square metre than in 2024. Finished floor space is the scarce thing; turning it into chip floors is the step still open.
US
Equinix booked a record $533 million of annualized gross bookings in Q3 2026 and plans more than 13,000 cabinets in Q4, its biggest delivery quarter on record. Price is rising and churn is low. The utility and the builders are paid first; the stuck step is the install.

PJM refiled its plan to buy about 6,831 MW of new power capacity in a one-time auction from 1 March 2027, with each zone charged by how much large load, mostly data centers, it adds. The cost of the grid shortfall now follows the data center build.
Explained
Data center power equipment is made by a small group of industrial firms. GE Vernova had 122 GW of gas equipment booked or reserved in September 2026, and Korea’s HD Hyundai Electric says its slots are full. The factory is the stuck step.
Malaysia
Malaysia has approved 117 data centres but only 55 are running, and 24 new applications now wait until states confirm there is enough water. Selangor has been asked for 634 million litres a day and has room for about 60. Water sellers and builders get paid first.
Analysis
Caterpillar takes large engine orders into 2029, Cummins delivers new 95-litre sets in late 2028 and Generac's data centre backlog nearly tripled. The engine, not the box, is the stuck step. Who gets paid, who waits, three scenarios.
Hyperscalers
SpaceX builds and runs AI data centers in Memphis and Southaven, trains Grok, and rents about half its compute to others. Revenue is surging, but turning on power and cooling for new GPUs is the step that binds.
Australia
A new industry forecast shows Australia’s data centre pipeline up 5.2 GW since April, with Sydney down 3.6 GW and Melbourne up 1.7 GW. Only 0.1 GW was switched on. Melbourne’s fast permits did the sorting, and now that lane is pausing for an election.
Explained
A 2nm chip is built on a foundry's newest process, where the transistor gate wraps all the way around stacked silicon sheets. TSMC's 2nm was 8% of its wafer revenue in the third quarter of 2026; capacity, not the design, is the stuck step.
Wire
Nvidia is in talks to guarantee billions of construction debt for Nscale's Anthropic data centre. The $44.6 billion contract is signed; the money to build is not. The loan needs a name lenders trust, and the chip supplier is offering its own.
Explained
A large AI data center is built to draw from about 100 MW to more than 1 GW, and the biggest running campus could use about as much electricity in a year as a million American homes. Most data centers draw far less than their grid hookup, and that gap decides who gets paid.

Intel expects 2026 PC units to fall about 12%, with the second half down more than 20%, as memory makers sell scarce chips to AI servers first. The memory crunch has moved from a cost problem for PC makers to a volume cut for the CPU makers behind them.
