The quantity of capital pouring into AI knowledge middle tasks is staggering. Final week, Microsoft, Alphabet, Meta, and Amazon reported their 2025 capital expenditures would complete roughly $370 billion, and so they anticipate that quantity to maintain rising in 2026. The largest spender final quarter was Microsoft, which put almost $35 billion into knowledge facilities and different investments, equal to 45 % of its income.
Hardly ever, if ever, has a single expertise absorbed this a lot cash this rapidly. Warnings of an AI bubble are getting louder day-after-day, however whether or not or not a crash ultimately occurs, the frenzy is already reshaping the US financial system. Harvard economist Jason Furman estimates that funding in knowledge facilities and software program processing expertise accounted for almost all of US GDP development within the first half of 2025.
In the present day, we’re how knowledge facilities are impacting three essential areas: public markets, jobs, and power.
Cashing Out
The US inventory market is booming, largely because of AI. Since ChatGPT launched in November 2022, AI-related shares have accounted for 75 % of S&P 500 returns and 80 % of earnings development, in keeping with JPMorgan’s Michael Cembalest. The query now’s whether or not that development can be sustainable as tech companies proceed spending closely on AI infrastructure.
At the beginning of this 12 months, tech giants have been financing their AI tasks largely with money they’d available. As monetary journalist Derek Thompson identified, the ten largest US public firms kicked off 2025 with traditionally excessive free money stream margins. In different phrases, their companies have been so worthwhile that they’d billions of {dollars} sitting round to place in the direction of Nvidia GPUs and knowledge middle buildouts.
That development has largely continued by 2025. Alphabet, for instance, advised traders final week that its capital expenditures this 12 months can be as a lot as $93 billion, a rise from its earlier estimate of $75 billion. Nevertheless it additionally reported that income was up 33 % 12 months over 12 months. Put one other method, Silicon Valley is each spending extra and incomes extra. Which means all the pieces is okay, proper?
Not precisely. For one factor, tech giants seem like utilizing accounting tips to make their financials look rosier than they could actually be in actuality. A good portion of AI funding flows to Nvidia, which releases new variations of its GPUs roughly each two years. However firms like Microsoft and Alphabet are at present estimating that their chips will final six years. If they should improve sooner to remain aggressive—a probable chance—that would wind up consuming into their earnings and weaken their total efficiency.
