Who builds and equips the data centers?
The companies that build, cool, wire and run the data centers where AI computing happens.
Variable 5: The power to run AI, not the chips, now sets the pace.
Spare rented computing capacity moves work around; it does not cancel new power and cooling construction, which follows capital spending, not chip scarcity.
Hyperscaler capital-spending guidance cut at the late-October reports; or a data center of 100 megawatts or more publicly deferred citing surplus; or Vertiv cutting its growth guidance. (Vertiv stopped reporting quarterly orders and backlog in February; we watch deferred revenue and growth guidance instead.)
The summer sell-offs on beat-and-raise reports are the market paying less for earnings, not the businesses failing. They reverse when the price of money stops rising.
At the late-October to mid-November prints, companies that beat and raise keep falling while companies that miss hold. That would say the market is pricing the businesses, not the money.
