IREN now targets more than $4 billion in annualized AI cloud revenue by January 2027. It has identified funding for $9 billion of its remaining $15 billion in planned spending.
A later target, and a larger funding gap
IREN’s AI cloud business is gaining ground, but its expansion schedule and financing needs show how much execution depends on customers, suppliers and access to capital. The bitcoin miner turned cloud provider now expects to exceed $4 billion in annualized run-rate revenue in January 2027, rather than by the end of this year. The company said the date could slip again, to late February. That range matters: the target is a forecast tied to a buildout that still has moving parts, not revenue already coming through the door.
Run-rate revenue offers a snapshot of the pace a business would generate if current activity continued; it isn’t the same as revenue earned over a full year. For a company adding data center capacity, that distinction is especially relevant. Infrastructure must be delivered and put into service before it can support customer workloads, and the projected revenue depends on those steps happening on schedule. IREN’s revised timing makes the gap between an ambitious target and completed capacity more visible.
That target’s underlying program is fully funded, IREN said. The larger buildout is a different matter: the company has $15 billion in planned capital spending remaining in fiscal 2027, which ends in June. Cash, committed GPU financing and customer prepayments cover roughly $9 billion. IREN expects to raise the remaining $6 billion through GPU and data center financing, prepayments and other sources, subject to market conditions. That gap represents 40% of the planned spending, by Unchained’s calculation, and is intended to support capacity beyond the $4 billion revenue target.
The distinction between funding the target and funding the broader plan is central to the story. IREN says the program tied to its stated revenue goal has financing in place, while the next stage depends on securing additional money. That gives the company room to pursue growth, but it also puts the pace of expansion in contact with financing conditions. If funds arrive more slowly or on different terms, the buildout could face pressure even if customer interest remains strong.
Customer changes shift delivery timing
Co-founder and Co-CEO Daniel Roberts attributed the revised schedule to “a customer-requested design change and supplier timing.” IREN didn’t identify the customer in its results. Reuters reported that Microsoft requested changes to the network design and that IREN won’t face financial penalties for the delay. The company said its Horizon 1 data center began service for Microsoft during the quarter.
A customer design change can affect more than a delivery date. In data center projects, network choices are part of how computing capacity connects and serves workloads, so revisions can require coordination across the customer, the operator and suppliers. The available details don’t show how extensive the requested changes were or what work they required. The schedule slip is clear; its precise operational cause isn’t.
IREN’s report that Horizon 1 began service for Microsoft provides a concrete sign of progress alongside the delay. But one facility entering service doesn’t settle the larger question of how quickly the company can bring additional capacity online. Customer requirements and supplier timing can shape that sequence, even when financing is available. And this is the part most people overlook: a signed customer relationship and a functioning site are milestones, while the wider expansion still has to be delivered.
The financing question is drawing attention across the sector. On Unchained’s Bits + Bips podcast in October, Coinbase head of institutional strategy John D’Agostino said bitcoin miners moving into AI hosting may think “the equity markets are tapped out,” while “the debt markets are starting to get skittish about that.” His comments point to the financing challenge facing companies that need to build expensive infrastructure before they can earn from it. IREN’s planned mix of funding sources shows why that challenge isn’t abstract: the company expects to raise $6 billion for spending beyond its currently covered amount.
AI cloud takes a larger share of revenue
IREN reported $228 million in revenue, up 66% from the previous quarter. AI cloud contributed $200 million, compared with $71 million three months earlier, and accounted for about 88% of revenue, according to Unchained’s calculation. Bitcoin mining revenue dropped to $28 million from $67 million. The figures show a sharp change in the company’s revenue mix within a single quarter: AI cloud has become the dominant reported source, while mining contributed less.
That shift helps explain why IREN is committing so much spending to data centers and GPUs. It also raises the bar for execution. As AI cloud becomes a larger part of reported revenue, delays in delivering capacity could have a more direct effect on the business’s growth plans. The numbers here are underwhelming in one respect: a fast-growing segment still has to be supported by equipment, facilities and funding before its latest pace can be treated as durable.
The net loss narrowed to $263 million from $684 million. Adjusted EBITDA increased to $66 million from $19 million. Revenue backlog rose 22% to $20.3 billion, with about two-thirds linked to investment-grade counterparties. These measures tell different parts of the story. Backlog indicates contracted future business, while the loss and adjusted EBITDA describe results in the reported period; none alone shows how quickly planned capacity will turn into delivered services and cash coming in.
Since the quarter ended Sept. 30, IREN has expanded a contract with an unnamed frontier AI lab and signed a five-year agreement priced at about $22 million per megawatt. The customer is prepaying 90% of the associated GPU spending, offering a direct source of funding for that deployment. Customer prepayments can connect a project’s funding to demand for its capacity, reducing the amount the company must raise for that particular GPU spending. The disclosed terms don’t establish that the same arrangement will apply to the rest of the buildout.
What the next phase depends on
For IREN, the next phase depends on converting contracted demand into operating capacity while arranging the money to build beyond the funded program. Those tasks are linked: customers can help support deployment through prepayments, but their specifications and suppliers’ schedules can affect when capacity is ready. Financing can support construction, but the company says a substantial portion of planned spending still needs to be covered.
If you're working in this space, the useful question is how those dependencies line up: whether customer commitments, equipment financing and facility delivery advance at a pace that supports the company’s target. IREN’s growing AI cloud contribution is evidence of a business taking shape, and its revenue backlog suggests a significant pool of contracted demand. Yet the January 2027 goal remains exposed to timing, and the additional spending plan remains exposed to markets. A narrower loss and higher adjusted EBITDA are progress; they don’t remove those execution requirements.
IREN shares closed at $18.03 on Thursday, down about 17%, before the results were released, according to price data. That move came before the results, so it can’t be read as a reaction to the reported figures. Roberts said IREN’s ownership of “the land, the power and the data centers” gives it more options for financing growth and controlling its pace. Owning those assets may give the company choices over how it develops capacity; the next test is whether those choices can cover the funding gap and meet customer schedules.
More capacity. More capital to find.
