In this week’s podcast, Nucleus Wealth’s Chief Investment Officer, Damien Klassen, revisits the data centre investment boom — exploring whether the world is on track to build more capacity than it needs, how modular data centres are changing the economics of expansion, and whether the enormous pipeline of projects still underway can be justified by future AI demand.

Key Talking Points:
-
AI data-centre construction remains strong: Major technology companies continue expanding capacity, despite some project delays and cancellations.
-
Electricity is the biggest bottleneck: Grid connections, power shortages, and local opposition are slowing new data-centre developments.
-
Behind-the-meter power is expanding: Data-centre operators are increasingly using temporary gas turbines and other onsite solutions to bypass grid delays.
-
Natural gas will play a major role: Cheap US gas, combined with battery storage and solar, is expected to supply much of the additional power needed.
-
Nuclear power is still years away: Most new nuclear agreements are conditional, and meaningful capacity is unlikely to arrive for roughly a decade.
-
Supply-chain constraints remain widespread: Transformers, turbines, cooling systems, construction materials, memory, and networking equipment are all limiting expansion.
-
Hyperscaler spending is rising rapidly: Google, Microsoft, Amazon, and others are increasing capital expenditure to support strong AI-related revenue growth.
-
Debt risks are growing but manageable: AI-related borrowing and complex financing arrangements are increasing, although major companies remain less leveraged than typical industrial businesses.
-
Vendor financing deserves attention: Nvidia and other suppliers are helping finance customers’ purchases, creating potential circularity within the AI investment cycle.
-
Memory-chip profits are highly cyclical: High-bandwidth memory manufacturers are benefiting from strong demand, but their earnings could become volatile when the cycle turns.
-
China is challenging the AI business model: Free and increasingly capable Chinese models could put pressure on the pricing and profitability of Western AI companies.
-
An AI overbuild will eventually happen: The speaker expects excess capacity at some point, but supply constraints and strong profits suggest it has not arrived yet.
-
Profit growth remains the key indicator: Despite concerns over debt, energy, and capital spending, sustained cash-flow and earnings growth continues to support the AI investment cycle.
