Introduction

  • TL;DR: Media summaries put 2026 Big Tech AI infrastructure spending $650B at roughly $650B, while Reuters frames it as more than $630B. (Bloomberg.com)
  • Amazon guided about $200B (company-wide capex), Alphabet guided $175B–$185B, and Meta guided $115B–$135B including finance lease principal payments. (Amazon)
  • The “total” varies mostly because definitions (leases vs cash PP&E) and periods (calendar vs fiscal year) don’t line up perfectly across companies. (Microsoft)

Context (first paragraph): 2026 Big Tech AI infrastructure spending $650B is a shorthand for a hyperscaler capex super-cycle aimed at AI data centers, accelerated computing, and networking. Reuters describes the same theme as over $630B combined. (Bloomberg.com)

Fact sheet: what the $650B label includes (and what it doesn’t)

Definition, scope, and a common misconception

  • Includes: data center build-out, servers/accelerators, networking (and sometimes finance leases). (Alphabet Investor Relations)
  • Not the same as: operating expenses like R&D payroll (though capex drives depreciation and power Opex). (Alphabet Investor Relations)
  • Misconception: “it’s all GPU purchases.” Microsoft explicitly splits spend across GPUs/CPUs, long-lived assets, and finance leases. (Microsoft)

Why it matters: If you don’t normalize definitions (leases, cash PP&E, time period), cross-company comparisons break immediately. (Microsoft)

Verified 2026 capex guidance (official IR) vs media totals

Official guidance you can verify directly

  • Amazon: “expect to invest about $200B in capex across Amazon in 2026.” (Amazon)
  • Alphabet: $175B–$185B capex range, with capex mix details (servers vs data centers/networking). (Alphabet Investor Relations)
  • Meta: $115B–$135B including finance lease principal payments. (Meta)

Media totals (why they differ)

Why it matters: “$650B” is a useful headline, but the decision-grade view is company-by-company, definition-by-definition. (Bloomberg.com)

Where the money goes: compute, data centers, and power

Compute + facilities + electricity

  • Alphabet describes capex largely as technical infrastructure, and even provides a servers vs data center/networking split. (Alphabet Investor Relations)
  • Microsoft reports quarterly capex and notes a large share going to GPUs/CPUs, plus finance leases for large data center sites. (Microsoft)
  • IEA links AI growth to rising data center electricity demand and power-supply planning. (IEA)

Why it matters: The constraint is not only chips; it’s land, power, cooling, and supply chains—capex is the visible tip of that stack. (Microsoft)

Market expectations vs “AI bubble” worries (what’s grounded)

What’s grounded in reporting

  • Reuters ties the capex surge to tighter investor scrutiny over returns on invested capital. (Reuters)
  • FT reports that the scale of spending revived “AI bubble” fears in market narratives. (Financial Times)
  • WSJ highlights how Amazon’s $200B capex plan shocked expectations and amplified volatility. (The Wall Street Journal)

Why it matters: You don’t need to “call a bubble” to act rationally—track whether capex translates into measurable unit economics and durable margins. (Reuters)

Conclusion

  • The “$650B” headline is supported as a media aggregation; Reuters frames it as $630B+. (Bloomberg.com)
  • Amazon/Alphabet/Meta provide directly verifiable 2026 guidance; Meta’s definition explicitly includes finance leases. (Amazon)
  • Electricity and power supply are part of the real bottleneck story, not an afterthought. (IEA)
  • Investor focus is shifting from “AI excitement” to “returns and cash-flow discipline.” (Reuters)

Summary

  • $650B (Bloomberg) vs $630B+ (Reuters) reflects definition/period differences. (Bloomberg.com)
  • Verified guidance: Amazon $200B, Alphabet $175–185B, Meta $115–135B (incl. finance leases). (Amazon)
  • Power constraints matter as much as GPUs in scaling data centers. (IEA)
