AI Infrastructure Investment Tracker 2026.

A source-linked institutional snapshot of the capital build-out behind artificial intelligence: hyperscaler capex, data-center investment, compute demand and the power constraint shaping where new capacity can be built.

MIDA reported cumulative data-center-related investment from 2021 through H1 2026.

Headline Signals

The build-out is becoming a capital market in its own right.

The most useful 2026 signal is not a single company budget. It is the convergence of hyperscaler spending, data-center construction, semiconductor upgrades and power availability. These figures are not directly additive because they use different scopes and accounting bases; the tracker keeps each source in its original frame.

Long-range infrastructure
$31.6T

Compute capacity becomes a multi-decade capex cycle.

PwC projects cumulative global AI-infrastructure investment of US$31.6 trillion through 2050, with annual data-center capex rising from roughly US$800 billion in 2026 to US$1.8 trillion by 2050.

Cloud capital expenditure
$886.7B+

Nine major CSPs accelerate infrastructure spending.

TrendForce estimated that combined 2026 capex for Google, Amazon, Meta, Microsoft, Oracle, ByteDance, Tencent, Alibaba and Baidu would exceed US$886.7 billion, approximately 90% higher year over year.

Regional infrastructure
RM95.8B

Malaysia's 2026 approved projects show regional depth.

MIDA reported RM95.8 billion of data-center and cloud-computing projects in the referenced 2026 period, while cumulative data-center-related investment from 2021 through H1 2026 reached RM385.7 billion.

Tracker Table

Comparable only within source definitions.

NEXUS preserves the stated scope of each source rather than normalizing incompatible figures into a single artificial total.

Important: hyperscaler capex includes non-AI infrastructure and different companies report capital expenditure on different accounting bases. NEXUS therefore treats these as directional indicators, not a sum-of-parts estimate.
Methodology

Source first.

  • Use named public sources with a visible publication date.
  • Keep the original unit, geography and scope.
  • Do not convert company-wide capex into “AI capex” without an explicit source.
  • Refresh after major earnings or infrastructure guidance updates.
  • Retain source links so every headline figure can be independently checked.
