At a glance

  • AirTrunk is the only Australian-built operator in Data Centre Magazine’s 2026 data centre M&A top 10, and it appears in two separate entries.

  • At number two sits Blackstone’s more than US$16 billion (A$24 billion) acquisition of AirTrunk, announced in September 2024 and still the largest data centre transaction in Asia-Pacific history.

  • At number seven sits AirTrunk’s own April 2026 acquisition of India’s Lumina CloudInfra, which adds about 600MW of planned capacity and marks the platform’s entry into the Indian market.

  • The two entries show AirTrunk moving from acquisition target to regional acquirer within eighteen months, exporting Australian-anchored capital across APAC.

  • Inside Australia, 2026 has produced little domestic change-of-control M&A on this scale. The year’s largest commitments have been greenfield investment and hyperscale leasing, not consolidation.

What the ranking says about Australia

Data Centre Magazine published its 2026 ranking of the ten most significant data centre mergers and acquisitions on 3 June 2026. The list is topped by the US$40 billion acquisition of Aligned Data Centers by a BlackRock-led consortium, with Microsoft and NVIDIA among the backers. Below it sit deals involving KKR, Singtel, SoftBank, Equinix and Bain Capital.

One Australian name appears twice. AirTrunk holds both number two and number seven. No other Australian operator features. NEXTDC, CDC Data Centres, Macquarie and GreenSquareDC are absent, though Macquarie Asset Management appears in the supporting cast as a seller in the AirTrunk deal.

The deal that put Australia on the global map

Blackstone’s acquisition of AirTrunk, announced in September 2024, valued the operator at more than US$16 billion (A$24 billion) including capital commitments. The sellers were Macquarie Asset Management, PSP Investments and co-investors. The buyer was Blackstone, alongside the Canada Pension Plan Investment Board.

Founded in Sydney by Robin Khuda, AirTrunk gave Blackstone an operating platform across Australia, Japan and Singapore at the moment hyperscale and AI demand began to reprice digital infrastructure as a core utility. The transaction remains the largest data centre acquisition in the Asia-Pacific region and one of the largest globally, behind only the Aligned deal on this year’s list.

A platform built in Sydney commanded the second-largest data centre acquisition price on the planet, a benchmark that reset how global capital values Australian-built infrastructure. We covered AirTrunk’s regional standing in our analysis of Australia’s top 10 APAC data centres, where the operator led the field.

AirTrunk as the buyer

In April 2026, AirTrunk acquired Lumina CloudInfra to enter the Indian market, an internal consolidation within the broader Blackstone portfolio. The deal adds roughly 600MW of planned capacity and, by AirTrunk’s account, up to US$5 billion of development potential across Mumbai, Chennai and Hyderabad. Financial terms were not disclosed.

The acquisition takes AirTrunk past 3GW of operating and planned capacity across 20 campuses in six markets: Australia, Singapore, Japan, Malaysia, Hong Kong and now India. It sits inside a larger ambition. AirTrunk has flagged a US$30 billion investment program to build more than 5GW of capacity in India by 2030, backed by Blackstone and the Canada Pension Plan Investment Board.

How 2026 compares inside Australia

Domestic acquisitions of comparable scale to the 2024 AirTrunk buyout have not recurred this year. The closest recent precedents both predate 2026: Partners Group’s up to A$1.2 billion investment in GreenSquareDC in March 2025, and HMC Capital’s A$400 million acquisition of iseek into its DigiCo platform in late 2024. At more than US$16 billion (A$24 billion), the AirTrunk buyout is roughly twenty times the size of the GreenSquareDC deal and about sixty times the iseek deal, the next-largest Australian data centre acquisitions of the past two years. No 2026 domestic transaction has come close.

Where the money has gone in 2026 is build and lease, not ownership change. The largest Australian commitments of the year are capital expenditure and contracts rather than acquisitions:

The pattern is consistent with a market still in its expansion phase. Consolidation tends to follow build-out, not lead it. Australia in 2026 is laying capacity and signing tenants, which is what capital flows look like before a wave of M&A, not after one. We set out the timing pressure in our analysis of Australia’s 12-to-18-month window, and the capital flows behind the APAC supercycle point the same way.

What to watch

The next test is whether Australia produces a 2026 or 2027 change-of-control deal that re-enters this kind of list on domestic terms. AirTrunk’s two entries show the playbook works both ways for an Australian platform. NEXTDC offers the clearest near-term tell. In April 2026 it raised A$2.2 billion, a A$1.51 billion equity offer at A$12.70 a share plus A$750 million in notes, to self-fund its S4 Western Sydney build, lifting pro forma liquidity to about A$6.6 billion. At a market value near A$9 billion, NEXTDC is funding growth to stay a builder rather than positioning as a target.
