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
Vertiv's customers had prepaid $4.1 billion by 30 September, 3.6 times a year earlier, as organic orders more than doubled. Power and cooling gear between the grid and the rack is now a step AI data center builders pay to queue for, and their cash is funding Vertiv's inventory.
Explained
AI chips are tested by four kinds of company: tester makers, probe card and interface makers, outsourced test houses, and foundries and chip firms with their own floors. Longer tests per chip make tester time the stuck step.
Malaysia
Johor's data centres could need 30 TWh a year by 2031, more than 90% of the new power Peninsular Malaysia is set to add, BMI says. TNB promises approved halls a grid hook-up within a year. Cable and substation builders are paid now. The local connection is the stuck step.
Analysis
SK hynix numbered LTAs covering more than half of 2027 and 2028 capacity, and a ₩100 trillion cheque. Who is paid if the sold book, not the cheque, is the stuck step.
Semiconductors
Tokyo Electron sells the coater/developer tracks that sit beside every scanner, plus etch, deposition and clean: it gets paid when a tool or Field Solutions is recognised, while the die still waits on an ASML slot.
Korea
SK hynix on 28 October printed ₩104.6 trillion of third-quarter sales and ₩83.3 trillion of operating profit, an 80% margin. Who gets paid is the memory maker on allocated HBM4. The stuck step is still those stacks.
Explained
An NVIDIA Cloud Partner is a specialist GPU cloud in NVIDIA's partner network. Offtake needs the API 12 weeks before the cards. Software readiness, not the badge, is the stuck step.
Wire
SK hynix posted ₩83.3 trillion of third-quarter operating profit on ₩104.6 trillion of revenue, set about ₩100 trillion of 2026 shareholder returns, and said long-term deals with 14 customers cover more than half of its 2027 and 2028 capacity.
AI Data Centers
Cipher Mining, renamed Cipher Digital in 2026, builds AI data center halls in West Texas and leases them to AWS and Fluidstack: 700 MW signed, $16.6 billion contracted, and only one of three campuses paying rent so far.
Wire
A Brookfield vehicle will fund up to $9 billion of GPUs and data centres by 2028 that Naver Cloud rents with fees tied to its revenue, guaranteed by Naver for up to eight years. The plan starts at 55 MW in the first half of 2027.
Catalyst
Amkor's computing sales rose 37% while total sales stayed flat, and a dozen customers have paid in advance for capacity. Chip packaging has joined silicon and memory as a step AI buyers pay to queue for, funding Korea and Arizona factories.
Explained
AI data centers are built by five kinds of company: hyperscalers, private developers, listed landlords, former bitcoin miners and the contractors on site. Contractors are paid as they build; everyone else waits for power-on.
