The contract that moved markets
On 5 May 2026, CDC Data Centres signed the largest data centre contract in Australian history – a 555MW deal with an unnamed US customer on a minimum 10-year term with renewal options stretching to 30 years. CDC is half-owned by NZX-listed Infratil, which holds a 49.72% stake.
The scale is difficult to overstate. That 555MW allocation alone equals roughly 40% of all operating Australian data centre capacity in 2025. It takes CDC’s total contracted capacity beyond 1GW by FY29, doubling from FY26 levels.
The market responded accordingly. Infratil surged 13.23% to $14.55 on 6 May, then climbed another 4.1% to $15.14 the next day. Its market capitalisation hit $14.54 billion, overtaking Auckland International Airport as the NZX’s third-biggest stock.
Infrastructure-grade returns, not speculative bets
What separates this from the breathless AI hype is the earnings profile. CDC expects EBITDAF to exceed A$1 billion in FY28 and reach approximately A$2 billion when fully deployed. Revenue quality is exceptional: more than 90% comes from investment-grade rated customers, with a weighted average lease expiry of 28.4 years. Moody’s assigned CDC a Baa2 stable outlook credit rating in April 2026.
Matt Goodson, managing director of Salt Funds Management, captured it well: the deal “derisks its growth path and catches up with what its peers have been doing overseas”.
Mark Lister, investment director at Craigs Investment Partners, put the NZX scarcity premium plainly: “There’s not many stocks that I can name locally that are linked to the AI theme. Infratil’s one of the few.”
The picks-and-shovels thesis, proven
Octagon Asset Management analyst Tobias Newton frames the structural logic: “If AI is the new industrial revolution, datacentres are the factories.” The value sits in location, grid connection, power access, cooling systems, connectivity, and approvals. The development economics are compelling, with Newton noting that “developing at 10% yields and exiting at 6% yields implies a 67% development margin”.
Global data centre IT load demand is projected to grow from 103GW in 2024 to more than 250GW by 2030. CDC’s pipeline stands at 2.9GW through to 2034, and founder Greg Boorer has indicated additional major contracts are expected to follow.
The execution risk nobody wants to talk about
The bull case is compelling but not risk-free. Newton warns that almost half of US data centres planned for 2026 face delays or cancellation due to shortages of transformers, switchgear, and batteries, with lead times blowing out to five years. CDC’s FY27 capex guidance of A$3.8-4.2 billion, more than double FY26’s A$1.9-2.2 billion, depends on navigating those same supply chains.
Newton draws a sobering historical parallel: since 2000, internet traffic volumes rose by half a million percent, yet capex on internet hardware fell dramatically. His conclusion: “The issue is not whether AI will prove transformative. The issue is whether the recent investment will be successfully monetised.”
Kiwi capital exports what Kiwi businesses won’t adopt
Here is the uncomfortable tension for New Zealand. BCG has identified data centres as a $70 billion strategic opportunity for the country, citing abundant renewable energy and strong fibre connectivity. But domestically, MBIE’s 2025 AI strategy found that 68% of NZ SMEs have no plans to evaluate or invest in AI, compared to only 38% of Australian SMEs.
Kiwi investors are capturing world-class returns from the infrastructure underpinning AI. Kiwi businesses, particularly the SME backbone, are largely sitting out the adoption wave those same data centres enable. Infratil just proved the picks-and-shovels thesis works. The question for every other NZ business owner is whether they plan to use the tools those shovels are building, or just watch the share price.
