The AI Buildout Is Nearing Its Existential Phase

Fear of missing out has driven data-center developers to build as much computing capacity as possible, as swiftly as they can. But investors funding the projects are getting nervous. They’re suddenly worrying that spending on artificial-intelligence services won’t be enough to justify the trillions of dollars backing the buildout.

Political opposition to the boom in server farms is growing, while construction delays, equipment failures and power constraints are hurting developers and slowing down projects. The latest concern is that projections for likely revenues from AI tools and services are coming up far short of what’s needed to deliver any return on investments in the vast computer facilities. For smaller infrastructure providers, that could prove deadly.

So-called neocloud companies such as Britain’s Nscale are feeling the pressure. Microsoft Corp.’s decision to pull out of a data-center project near London with the firm, for example, has cast doubts on Nscale’s planned US stock-market listing. Several other planned initial public offerings, including one for leading AI model-maker OpenAI, have been put on ice. Meanwhile, the public shares and bonds of another neocloud, CoreWeave Inc., have been hammered, and the Philadelphia Semiconductor Index had an eight-day losing streak through the end of last week, its longest since 2008.

All of the players in this infrastructure boom, from upstarts such as Nscale to giants including Alphabet Inc., are chasing the idea that whoever gets the most chips humming can lock in the biggest contracts and win the AI computing race. “We are in a period where you have to be huge,” CoreWeave co-founder Brannin McBee told the Financial Times in an interview full of bubble-blowing hubris.

This mindset has driven the dizzying escalation of capital spending plans. At the start of this year, analysts estimated that the five hyperscalers alone — Alphabet, Amazon Inc., Meta Platforms Inc., Microsoft and Oracle Corp. — would spend $630 billion on new data centers in 2027. That forecast has now almost doubled to $1.1 trillion.
