The ASX AI Infrastructure Boom Is Real: 5 Data Centre Stocks Riding the Wave

 5 ASX Data Centre Stocks Riding the AI Infrastructure Boom

The past 24 hours have made one thing clear. The ASX data centre boom is no longer about future demand. It is happening right now, in real contracts and real money. DigiCo Infrastructure REIT (ASX:DGT) jumped 23% on Wednesday after selling its Chicago facility for US$750 million to fund a Sydney expansion. Infratil (ASX:IFT) climbed 12% after its CDC arm signed a 30-year, 555MW deal, the biggest data centre contract Australia has ever seen.

The takeaway for investors is simple. Australian data centre operators are no longer chasing customers. They are turning customers away because power and capacity are running short. If the SaaSpocalypse showed where capital is leaving, the data centre boom shows where it is going. The companies with land, power, and the right partnerships are sitting on a multi-year growth runway.

What are the Best ASX Stocks to invest in right now?

Here are the five ASX data centre stocks at the centre of it

DigiCo Infrastructure REIT (ASX:DGT)

DigiCo has finally done what frustrated holders were hoping for. The Chicago sale cuts gearing from 36% to 17% and frees up cash to accelerate its 88MW Sydney project. The story moves from “too much debt” to “build the next stage.” The stock remains below its A$5 IPO price, which we believe leaves room for a re-rating if Sydney demand turns into signed contracts.

Infratil (ASX:IFT)

Infratil owns about half of CDC, and CDC just landed a deal that changes the whole investment case. The 555MW contract with a US investment-grade customer (almost certainly a hyperscaler) lifts CDC’s contracted capacity above 1GW. Earnings are guided to top A$1 billion by FY28, and around A$2 billion once fully deployed. Best of all, no capital raise is needed, so existing shareholders won’t be diluted.

NextDC (ASX:NXT)

NXT is the purest data centre play on the ASX. Contracted utilisation jumped 60% in just three months, hitting 667MW by the end of March. To meet that demand, NXT raised A$1.5 billion in April to fast-track its S4 Western Sydney campus. Add a recent OpenAI partnership for sovereign AI infrastructure, and the growth pipeline looks deep. The catch is dilution and a high valuation, so NXT suits growth investors, not bargain hunters.

Macquarie Technology (ASX:MAQ)

At around A$1.7 billion market cap, MAQ is the smaller-cap option. Its edge is trust. Macquarie hosts 42% of the Australian Federal Government, an advantage competitors cannot easily copy. Its 47MW IC3 Super West facility opens in September 2026, with around 200MW more in the longer pipeline. For investors who want data centre exposure without paying premium multiples, MAQ is worth a closer look.

Goodman Group (ASX:GMG)

GMG is the global play. Around 73% of its A$14.4 billion development pipeline is now data centres, backed by a 6 gigawatt power bank across 16 cities worldwide. It’s a $14 billion European partnership with CPP Investments that shows big institutional capital is backing the strategy. The downside is the price tag. GMG trades at a premium valuation, so a lot of the good news is already in the share price.

The Investor’s Takeaway

Each stock plays the same theme differently. DGT and NXT for direct exposure, IFT for the contracted earnings story, MAQ for the sovereign small-cap angle, and GMG for global scale. The boom is real, but valuations are stretched in places. Investors should match the stock to their risk appetite and watch for delivery, not just announcements.
