Data centre funding hits a record $35 billion

The $35 billion figure and what drove it

Australian data centre operators have raised a record $35 billion so far in 2026, a 46 per cent increase on the $24 billion raised across the whole of 2025.^[1][2] The catalyst is a sustained build-out of computing and storage capacity to service demand from large-scale AI models, a wave of construction that began in earnest after late 2022 and has accelerated through each subsequent year.

Debt accounts for 85 per cent of that $35 billion total, a concentration sitting materially above the 60 to 80 per cent debt share observed in comparable United States build-outs.^[1] The equity share is being asked to carry less of the load here than in the world's deepest capital market, a structural feature of the Australian financing landscape that the yield curve is already beginning to price.

Who is lending and why syndicated debt dominates

Roughly $25 billion of 2026 data centre funding came through syndicated loans, the dominant channel for project finance of this scale.^[2] RBA analyst Bradley Speed said syndicated loans allow for greater loan sizes than with a single bank and are generally more accessible than the corporate bond market for firms without an investment grade rating.^[3] Many operators driving this build-out sit below investment grade, which closes the public bond market to them and makes a consortium of lenders the practical alternative.

About $25 billion of the total was raised via syndicated loans, a channel that pools risk across multiple lenders while allowing individual deal sizes that no single Australian bank would take on its own balance sheet.^[2] High land and power-infrastructure costs make up-front capital requirements large enough to push most projects toward this structure regardless of operator preference. That the debt share in Australia now exceeds the United States benchmark suggests lenders here have not yet imposed the equity discipline their American counterparts have, or that Australian operators have simply not had to offer it.

Bullock's inflation warning and the rate-rise outlook

Speaking at a CEDA event on 22 September, RBA governor Michele Bullock framed the AI construction surge as a near-term inflation problem. Bullock told the audience that Australia is in a situation of excess demand and the AI boom is adding to that demand ahead of any potential supply impacts that it might have going forward.^[4] The supply-side productivity gains that AI advocates promise are, on her reading, a future event; the demand-side pressure on labour and materials is arriving now.

Bullock added a financial-stability note worth reading carefully, telling the CEDA audience that while the data centre investment boom might not be a bubble, if it unwinds in a disorderly manner, it could have implications for the financial system and also for the real economies.^[4] Bullock said unemployment of between 4.5 and 5 per cent would take enough heat out of the labour market to ease inflationary pressures, a threshold the current market has not reached.^[4]

All four major banks expect the Reserve Bank to raise rates at its 28 to 29 September board meeting.^[5] A sector that has financed 85 per cent of a $35 billion build-out through floating-rate or refinanceable debt will feel a rate move more acutely than a comparable equity-heavy structure would, and the board convenes on 29 September.
