Blackstone's AirTrunk Pursues $1.6 Billion Loan Ahead of Singapore REIT Listing

Financing Structure Takes Shape

AirTrunk, the data centre operator controlled by Blackstone, is negotiating approximately $1.6 billion in debt from banks to support a real estate investment trust listing in Singapore, according to people with knowledge of the discussions. The company has approached lenders for multiple tranches spanning three to seven years, denominated in Singapore dollars and yen.

The REIT will raise the funds to acquire facilities from AirTrunk and refinance existing obligations, though final terms remain under negotiation. Neither AirTrunk nor Blackstone provided comment on the financing talks.

The transaction represents one of the larger debt packages tied to Asia-Pacific data centre assets this year. Regional lenders have extended nearly $29 billion in data centre loans since January 2025, pushing many institutions toward internal sector exposure caps.

Selective Lending Environment

Banks across the region have grown more cautious about data centre credit, prioritising borrowers with established track records and strong sponsor backing. AirTrunk's affiliation with Blackstone continues to attract lender interest even as smaller operators face rejection, people familiar with bank lending criteria said.

The company secured $2.3 billion in green financing earlier this year for a hyperscale campus in Johor Bahru, Malaysia, underscoring its access to large-scale credit. That facility added to billions already committed for build-outs across South-east Asia and Japan.

AirTrunk is also exploring asset-backed bond structures, a mechanism gaining traction among lenders seeking to free balance sheet capacity for additional data centre exposure. The REIT listing itself offers another avenue, shifting assets off AirTrunk's books and broadening the investor base beyond traditional project finance.

REIT Pathway

People familiar with the IPO preparations said AirTrunk is nearing confidential filing for the REIT, which earlier estimates suggested could raise around $1.5 billion. The offering will bundle operating data centres into a publicly traded vehicle, providing liquidity and a benchmark for similar structures in the region.

Singapore has emerged as a preferred domicile for data centre REITs, with existing trusts pursuing acquisitions in Japan and other markets where power availability and grid reliability exceed levels in land-constrained South-east Asian hubs. The AirTrunk REIT will join a cohort of trusts competing for institutional capital amid rising electricity costs and tighter data centre permitting.

Regional Financing Pressure

The proposed loan highlights the tension between surging demand for data infrastructure and finite bank lending capacity. Financial institutions in Singapore, Hong Kong, Tokyo and Sydney have written the majority of data centre credit in Asia, with Singapore-based lenders accounting for 98 per cent of $11.5 billion raised across South-east Asia in recent reporting periods.

As artificial intelligence workloads drive construction pipelines, banks are experimenting with syndication, securitisation and co-lending arrangements to manage concentration risk. The AirTrunk transaction will test whether multi-currency, multi-tranche debt can attract sufficient participation without triggering margin inflation or covenant tightening.

Energy availability remains a constraint. Several planned facilities in Singapore and Malaysia have faced delays tied to grid connection timelines, while Japan's stable power supply has made it a magnet for expansion. AirTrunk operates campuses in Sydney, Melbourne, Tokyo, Osaka, Hong Kong and Singapore, with the Johor project adding 100 megawatts of IT load capacity.

Market Implications

The REIT IPO, if completed at the earlier $1.5 billion estimate, would rank among the largest Singapore listings this year and set a valuation reference for comparable assets. Proceeds will enable AirTrunk to recycle capital into new developments while maintaining operational control through management contracts.

Blackstone acquired AirTrunk in 2024 for more than $16 billion, one of the largest data centre transactions globally. The REIT structure allows the private equity firm to monetise mature assets while retaining upside exposure through its stake in the operating company.

Lenders participating in the debt package will gain exposure to investment-grade-style credit backed by long-term customer contracts, typically spanning seven to fifteen years with hyperscale cloud providers and enterprise clients. The yen tranche reflects Japanese investor appetite for yield-bearing infrastructure debt, a segment that has absorbed significant data centre paper over the past two years.

Whether the loan draws broad syndication or concentrates among a core group of relationship banks will signal lender confidence in Asia's data centre financing outlook. Terms, pricing and covenant flexibility will be closely watched by other operators planning similar capital structures.
