AI Infrastructure Gap: $1.8tn Contracted — $700bn+ CAPEX

Sep 25
3 min read

10 September 2026



Evolution: Oil → Gas → LNG → Power → Power for AI

Key Points


  • $1.8tn — contracted future business 

  • $700bn+ — planned CAPEX (2026) 

  • 17 GW — AI data-centre capacity delivery gap


$1.8 Trillion — Contracted Future Business


  • $678bn — Microsoft $638bn — Oracle $514bn — Google Cloud [1–3]

  • $700+ Billion — Planned CAPEX in 2026

  • $200bn+ — Amazon $200bn — Alphabet $175bn — Microsoft $130–145bn — Meta [4]


85 GW — In Development (458 Facilities)


  • 24 GW — fully secured 

  • 68 GW — upper delivery projection 

  • 17 GW / 20% 🔴 — delivery gap (2030) [5]


Critical Resources


  • 🔴 Power — generation + grid connection 

  • 🔴 Land — powered sites + fibre access

  • 🔴 Cooling — water + heat rejection. 

  • Nearly 5 years — median grid-connection waiting time [6]


Delivery Models

1. Conventional

Land → Power → Cooling → Data Centre Proven. Scalable. Core industry model.

2. Modular

Factory → Modules → Transport → Installation → Connection 


  • 🟢 Site Labour ↓ — less on-site construction 

  • 🟢 Parallel Execution — factory + site work 

  • 🟢 Quality ↑ — controlled fabrication and testing 

  • 🟢 Schedule ↓ — faster deployment potential Location — fabrication in lower-cost locations Replication — repeatable designs across multiple projects


3. Floating

Fabrication Yard → Floating Platform → Power Location → Operation 


  • 🟢 Land ↓ — minimal land requirement 

  • 🟢 Cooling — seawater heat rejection 

  • 🟢 Construction — yard fabrication and integration 

  • 🟢 Mobility — relocation between locations 

  • Expansion — additional modules / platforms 

  • Decommissioning — removable infrastructure


25-Year Hull vs 5-Year Compute → Replaceable Compute Modules

The Opportunity

85 GW Pipeline → 68 GW Delivery → 17 GW Gap

The Race for Delivery

Who will convert capital into powered computing capacity fastest? Conventional → Modular → Floating

We are exploring modular and floating AI data-centre ideas at an early stage and would welcome dialogue with infrastructure investors and strategic financial partners interested in the next generation of AI infrastructure.

Methodology


  1. Contracted Business — Microsoft/Oracle RPO + Google Cloud backlog; future contracted business, not AI-only.

  2. CAPEX — 2026 company guidance/estimates; approximate and not AI-only.

  3. Pipeline — 458 AI data-centre facilities / 85.4 GW in active development worldwide.

  4. Delivery — ClusterBid projects 62–68 GW operational by 2030. The 17 GW / 20% gap is the difference between the 85.4 GW pipeline and upper 68 GW projection.

  5. Concepts — Modular/floating are early-stage concepts subject to project-specific assessment.

  1. Microsoft Investor Relations — FY2026 Q4: $678bn commercial RPO.

  2. Oracle Investor Relations — FY2026: $638bn RPO.

  3. Alphabet / Google — Q2 2026: $513.9bn Google Cloud backlog.

  4. Amazon | Alphabet | Microsoft | Meta — 2026 CAPEX guidance/outlooks.

  5. ClusterBid — AI Data Center Construction Pipeline 2026–2028: 458 facilities / 85.4 GW; 28% fully de-risked; 62–68 GW projected operational by 2030.

  6. Lawrence Berkeley National Laboratory — grid-connection queue analysis: nearly five-year median request-to-commercial-operation timeline in 2024.

  7. Meta / Amazon SEC filings — approximately five-year useful life for AI/server equipment.

  8. Microsoft Investor Relations — FY2026 Q4 (29 Jul 2026): useful life of data-centre and office buildings extended from 15 to 25 years, effective FY27. Offshore engineering references — approximately 25-year marine hull design-life basis.
