AI Infrastructure Gap: $1.8tn Contracted — $700bn+ CAPEX
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
Contracted Business — Microsoft/Oracle RPO + Google Cloud backlog; future contracted business, not AI-only.
CAPEX — 2026 company guidance/estimates; approximate and not AI-only.
Pipeline — 458 AI data-centre facilities / 85.4 GW in active development worldwide.
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.
Concepts — Modular/floating are early-stage concepts subject to project-specific assessment.
