The artificial intelligence buildout is being driven primarily by five hyperscalers—Alphabet, Amazon, Meta, Microsoft, and Oracle—and has effectively become a capital-expenditure sprint with an eventual price tag expected to be in the trillions, most of it committed to constructing the massive data centers and cloud infrastructure AI requires.
