The Data Centre Supercycle: What It Means for ASX Growth Stocks Like Goodman Group (ASX:GMG)

The Buildings Behind the AI Boom

Everyone talks about artificial intelligence. Fewer people talk about where AI actually lives.

Behind every chatbot, cloud service, and streaming platform sits a massive building packed with servers, running around the clock. These are data centres, and right now, the world cannot build them fast enough.

For Australian investors, this creates a surprisingly direct opportunity through the ASX.

Why the Demand Is Unlike Anything We've Seen Before

The world's five largest technology companies, including Amazon, Microsoft, and Google, are expected to spend a combined US$600 billion on infrastructure in 2026. That is roughly 36% more than 2025, and nearly triple what they spent just two years ago.

About 75% of that spend goes directly into AI infrastructure, including data centres.

The reason spending keeps rising is simple. AI services need to run in real time, close to users, 24 hours a day. That requires specific locations, near major cities, with access to large amounts of reliable power. Microsoft has reportedly disclosed a US$80 billion backlog of cloud orders it cannot fulfil because of power constraints alone.

The bottleneck is not chips or software. It is land and electricity in the right places.

This is why the companies that locked in city-fringe sites and grid connections early are now sitting on something genuinely hard to replicate.

Australia's Place in the Picture

Australia is well-positioned in this global buildout. It offers a stable investment environment, growing renewable energy capacity, and sits at the gateway to the Asia-Pacific region, one of the fastest-growing data centre markets in the world.

The Asia-Pacific data centre market is estimated at around US$35.8 billion in 2026 and is forecast to nearly triple to US$94.1 billion by 2031.

For investors focused on data centre stocks in Australia, this is a meaningful tailwind.

How Goodman Group (ASX: GMG) Fits In

Among all ASX-listed companies, Goodman Group offers the most direct exposure to this theme.

Goodman owns, develops, and manages industrial and digital infrastructure in major cities around the world. Data centres now make up 73% of its A$14.4 billion development pipeline, up from just 42% eighteen months ago.

The company reported A$1.2 billion in operating profit for the first half of FY26, with external assets under management sitting at A$75.2 billion. Its global power bank has grown to 6.0 gigawatts across 16 cities, with 0.5 GW of data centre projects expected to be under construction by June 2026.

To fund this growth without overextending its balance sheet, Goodman has secured a A$14 billion data centre development partnership in Europe and a A$2 billion logistics partnership in the United States.

However, the valuation deserves attention. GMG shares trade at roughly 36 times earnings, and the stock fell 6% on results day despite a strong result. At this level, much of the good news may already be priced in, meaning the entry point matters just as much as the thesis.

Risks to Keep in Mind

• Power availability and rising energy costs remain genuine constraints
• Large construction projects can face delays
• GMG's premium valuation leaves limited margin for error
• Global competitors with deeper pockets are also expanding in Australia

Key Takeaways

• The global data centre buildout is structural, not a short-term cycle, and Australia is well placed to benefit
• Power access and city proximity are becoming scarce assets, creating real pricing power for early movers
• Goodman Group is the ASX's clearest proxy for this theme, but the premium valuation means entry price matters

This is a decade-long infrastructure story. For Australian investors, the opportunity is real but so is the need for careful research before acting.
