Power demand: +24% a year
McKinsey's estimate turns energy into the key variable of AI cost. Cloud regions with spare power will win workloads — ask your provider where your AI runs.

Capex keeps rising and power, not chips, is the new bottleneck
Amazon (~$220B) and Alphabet ($195–205B) raised 2026 capex again, and Nvidia guides to $108B next quarter. The constraint has moved to electricity: data-centre power demand grows 24% a year, utilities and nuclear are being financed for AI, and local opposition is now a planning risk. Expect AI capacity to stay tight — and priced accordingly — into 2027.
This week
Nuclear for AI gets a permit
The first US small modular reactor permit (TVA, 300 MW) and LS Power's record $6B fund show capital moving from chips to electrons.
Community pushback is now a cost line
Amazon's $1B for communities near its data centres signals that social licence is part of the build-out budget.
This month
China builds around its own chips
DeepSeek and Huawei open-sourced Ascend programming tools to reduce CUDA dependence — a parallel AI stack is forming.
What to watch next
- Q3 earnings (late October): any change in 2026–27 capex guidance
- EU AI gigafactory call — Spain and others are preparing bids
- Memory prices: they pushed Amazon's capex up by ~$20B
What to do
Lock in AI capacity and prices for 12 months where you can, keep a second provider ready, and ask for the data-centre region in every AI contract (cost, latency and GDPR depend on it).

Signals scored 9+ or structural shifts stay here for 90 days.
Finance
Nvidia posts $96.2B quarterly revenue (+106%), $89.0B from data centres, and guides to $108B
Data-centre revenue rose 117% year on year and management called next year's outlook supply-constrained. AI infrastructure demand shows no sign of slowing, which keeps GPU prices — and AI costs — firm.
