The build converts on schedule; the calendar and the uncommitted $6 billion are the open questions. [IREN](https://theinference.org/markets/companies/iren) [filed its first quarter as a Microsoft supplier tonight](https://www.sec.gov/Archives/edgar/data/1878848/000187884826000065/0001878848-26-000065-index.htm), and the document answers both camps at once. The bears who spent two days reading satellite imagery of an unfinished Texas data hall got their confirmation: the company's more-than-$4 billion run-rate target, promised for year-end, has moved to January 2027 and may stretch to February, after a customer-requested design change and supplier timing [1]. The bulls got something bigger: AI Cloud revenue of $200 million for the quarter ended September 30, nearly triple the prior quarter's $71 million, with an 86 percent segment gross margin [1]. *Chart: **Revenue dipped as mining faded, then the AI quarter pushed it past its 2025 peak** Column chart of IREN total revenue by calendar quarter from Q3 2024 to Q3 2026: rising from $36 million to a $240 million peak in the September 2025 quarter, dipping to $137 million, then jumping to $228 million in the September 2026 quarter.* *Total revenue by calendar quarter, in US dollars; the September 2026 quarter is IREN's fiscal first quarter of 2027.

[3][1]* ## From a construction story to a billing story The revenue line matters because it is the first hop of the chain proven in cash, not in renderings. Contracted compute actually went into service: Horizon 1 was delivered to [Microsoft](https://theinference.org/markets/companies/microsoft) during the quarter and earned [NVIDIA](https://theinference.org/markets/companies/nvidia) Exemplar status on its GB300 systems [1]. What was a construction story three months ago is now a billing story. Total revenue reached $228 million, up two-thirds sequentially, while bitcoin mining shrank to $28 million; this is now an AI infrastructure company that happens to own a shrinking mining tail [1]. *Chart: **AI Cloud revenue tripled in a quarter while bitcoin mining halved** Grouped column chart: AI Cloud revenue rises from $71 million in Q4 FY26 to $200 million in Q1 FY27 while bitcoin mining revenue falls from $67 million to $28 million.* *Segment revenue for the June 2026 quarter (Q4 FY26) and the September 2026 quarter (Q1 FY27), in US dollars.

[1]* ## Demand is not the bottleneck; the calendar and the money are The backlog grew to $20.3 billion, two-thirds of it owed by investment-grade counterparties, and pricing on new deals keeps rising [1]. Post-quarter, IREN signed a five-year contract at about $22 million per megawatt with 90 percent of the GPU capex prepaid by the customer, and a short-term deal at $40 million per megawatt [1]. When a customer prepays the hardware, it is telling you it fears scarcity, not oversupply. The bottleneck is the one the audit flagged: converting construction into accepted capacity, and paying for it. Horizon 2 through 4 are in late-stage construction [1], and the remaining fiscal-2027 capex is $15 billion, of which $9 billion is covered by cash and committed financing [1]. *Chart: **Cash and debt both multiplied more than tenfold in seven quarters to fund the build** Line chart of IREN cash and total debt by calendar quarter from Q4 2024 to Q2 2026: cash rises from $0.43 billion to $7.57 billion and debt from $0.32 billion to $7.84 billion.* *Cash and total debt at each calendar quarter-end, in US dollars, shown from Q4 2024 onward because earlier debt disclosures are not comparable.

[3]* ## January is the verdict The other $6 billion depends on market conditions [1], and [the 10-Q filed the same night](https://www.sec.gov/Archives/edgar/data/1878848/000187884826000066/0001878848-26-000066-index.htm) carries a new note purchase agreement and a guaranty [2], evidence the company is raising that money while lenders repriced exactly such paper this week. Watch whether the January delivery holds. If it does, the bears' timeline argument dies; if it slips again, the financing gap, not the contracts, becomes the story. The builder who gets these halls accepted on schedule is the one earning the value here, and tonight's filing says IREN is closer to being that builder than the satellite photos suggested. ## Takeaway AI Cloud revenue nearly tripled to $200 million and the backlog reached $20.3 billion, but the $4 billion run-rate target slipped to January or February and $6 billion of fiscal 2027 capex is still unfinanced. ## Sources 1.
