Big Tech's 2026 AI Capex Guidance Reaches $710B
The AI capital expenditure story remains not only intact but has significantly accelerated. In their Q1 2026 earnings reports, the four main U.S. technology hyperscalers (Amazon, Microsoft, Alphabet, and Meta) collectively spent $130.6 billion in capital expenditures in a single quarter, and they raised or reaffirmed their full-year 2026 capex guidance to an aggregate of approximately $710 billion.
These massive investments are driven by a shared, urgent sprint to build out AI data centers, with executives repeatedly stating that they are compute-constrained rather than demand-constrained.
The Breakdown of the $710B Capex Sprint:
- Amazon: Reaffirmed its massive $200 billion capex commitment for 2026, with the overwhelming majority of its spend tied to AWS and its AI infrastructure. In Q1 2026 alone, Amazon spent $43.2 billion on capital expenditures.
- Microsoft: Guided to $190 billion in calendar 2026 capex (up 61% from 2025), significantly exceeding the analyst consensus of $154.6 billion. CFO Amy Hood noted that this includes a $25 billion impact from soaring component (memory) prices.
- Alphabet/Google: Raised its full-year 2026 capex guidance range to $180 billion to $190 billion (up from its prior $175B–$185B range). It spent $35.7 billion on capex in Q1 2026 alone, and CFO Anat Ashkenazi guided that 2027 capex will "significantly increase" compared to 2026.
- Meta: Raised its full-year 2026 capex guidance to $125 billion to $145 billion (up from its prior $115B–$135B range). Meta reported Q1 2026 capex of $19.84 billion.
This unprecedented level of capital commitment provides a massive, highly visible demand runway for AI hardware providers, particularly NVIDIA, as detailed in Nvidia's Record Q1 Results and $1T Blackwell-Rubin Order Book.
