The quantity of capital pouring into AI knowledge heart tasks is staggering. Final week, Microsoft, Alphabet, Meta, and Amazon reported their 2025 capital expenditures would whole roughly $370 billion, and so they count on that quantity to maintain rising in 2026. The largest spender final quarter was Microsoft, which put practically $35 billion into knowledge facilities and different investments, equal to 45 % of its income.
Hardly ever, if ever, has a single know-how absorbed this a lot cash this shortly. Warnings of an AI bubble are getting louder each day, however whether or not or not a crash finally occurs, the frenzy is already reshaping the US economic system. Harvard economist Jason Furman estimates that funding in knowledge facilities and software program processing know-how accounted for practically all of US GDP development within the first half of 2025.
As we speak, we’re taking a look at 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 line with JPMorgan’s Michael Cembalest. The query now’s whether or not that development shall be sustainable as tech companies proceed spending closely on AI infrastructure.
Initially of this 12 months, tech giants have been financing their AI tasks largely with money they’d readily available. As monetary journalist Derek Thompson identified, the ten largest US public firms kicked off 2025 with traditionally excessive free money move margins. In different phrases, their companies have been so worthwhile that they’d billions of {dollars} sitting round to place in direction of Nvidia GPUs and knowledge heart buildouts.
That development has largely continued by way of 2025. Alphabet, for instance, informed traders final week that its capital expenditures this 12 months could 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 manner, Silicon Valley is each spending extra and incomes extra. Meaning every part is ok, proper?
Not precisely. For one factor, tech giants look like utilizing accounting methods to make their financials look rosier than they might 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 the moment estimating that their chips will final six years. If they should improve sooner to remain aggressive—a probable risk—that might wind up consuming into their income and weaken their total efficiency.
