Big Tech's 2026 AI Infrastructure Spending Tops $725 Billion

Overview

The largest U.S. technology companies have collectively committed more than $725 billion in capital expenditure for 2026, according to Q1 earnings reports released this week. The figure, which nearly doubles the combined $410 billion these four companies spent last year, reflects an unprecedented acceleration in AI data center buildout with no clear ceiling in sight.

Company-by-Company Breakdown

Microsoft: Projecting approximately $190 billion for the year; Q3 capex alone reached $30.88 billion, up 84% year over year.

Meta: Raised its 2026 capex guidance to $125–$145 billion, up from a prior range of $115–$135 billion. CEO Mark Zuckerberg framed it as building "personal superintelligence for billions of people."

Alphabet (Google): Projecting up to $185 billion in 2026, with Morgan Stanley estimates suggesting potential scaling to $250 billion by 2027.

Amazon: The only company among the four to hold its figures steady, at $200 billion for the year.

Market Reaction

Meta shares fell sharply after its earnings release as investors focused on the scale of spending plans. Microsoft also dipped. By contrast, Alphabet and Amazon rose on strong cloud growth numbers.

What This Means

Google's projected 2027 spend alone — $250 billion per Morgan Stanley — would exceed the combined capex of all four companies in 2025. The buildout shows no structural endpoint, with each company citing growing enterprise demand for AI compute as justification for continued acceleration.
