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.
Catalyst
Schneider Electric's data center orders are still growing faster than it can ship switchgear, UPS and prefab power rooms, so the electrical gear between grid and GPU hall tightens into 2027.
China
China's legacy 8-inch foundries have been running full on AI-server power semiconductors since the start of the year, while TSMC and Samsung cut capacity. Order books stretch about six months. Foundries are paid first; server builders wait on the wafers.
Analysis
Mason County named Meta on a 2.2 GW campus and a $10 billion first cheque. The wires have dates. The 396 MW first building already crosses the 250 MW dedicated-power line. Who is paid while the plant is still unnamed.
Analysis
The MGX 1.2 rack runs to 250 kW on a 48-volt, 5,000-amp busbar while NERC grid rules pass their final ballot. Who gets paid between the grid connection and the rack, arithmetic shown.
Wire
Mason County, Kentucky named Meta on 13 October as the developer of a planned 2.2 GW data center campus, with $10 billion to start and a 396 MW first building. Meta pays for about $566 million of new grid, but the stuck step is the dedicated power supply the state's tariff requires above 250 MW.
Hyperscalers
Meta converts advertising cash into captive AI halls: it gets paid when ads run, while the megawatts that would light those halls are still the stuck step.
Explained
An AI data center uses water mainly to cool servers. Microsoft’s fleet WUE was 0.27 L/kWh in FY25; Singapore’s PUB median is 2.1 m³/MWh. Who pays, and where wet cooling sticks.
Korea
Korea Customs on 15 Oct: $121.05B exports, $60.50B chips. ICT surplus $53.71B is larger than the whole surplus. Memory makers are paid; new wafer output still waits.
Explained
CoWoS puts an AI GPU and HBM on a full interposer. EMIB embeds small silicon bridges in the substrate. The stuck step is still the CoWoS slot, not the second recipe.
Explained
GPU financing lends against GPU servers and the customer contract that pays for them. The loan is drawn as servers go live and repaid from the customer's cash, so the stuck step is the day the customer accepts the site.
Wire
On 9 October Digital Realty offered De Soto, Kansas households up to $1,000 a year for 10 years, $20 million in all, ahead of a campus with 600 MW of power due by early 2028. No tenant is named, and a tax district hearing is set for 19 November.
Wire
TSMC's 15 October print puts 2-nanometer at 8% of wafer revenue and HPC at 68% of sales. Gross margin 66.4% on the N2 ramp; Q4 guides $52.3–54.3 billion. Demand is still above supply.
