IREN Shares Jump 20% as AI Cloud Revenue Hits $200 Million

IREN's stock closed up roughly 20% at $21.64 on Friday, Nov. 6, after the company reported fiscal first-quarter 2027 results showing its AI cloud business has rapidly overtaken Bitcoin mining as its core revenue engine.

AI cloud revenue reached $200 million for the quarter, a 182% jump from $71 million in fiscal Q4 2026. Bitcoin mining revenue moved in the opposite direction, falling to $28 million from $67 million as IREN redirected capacity toward AI workloads. Total revenue climbed 66% quarter-over-quarter to $228 million.

The margin picture explains the market's enthusiasm. The AI cloud segment posted an 86% gross margin, a level mining operations rarely approach. AI cloud now accounts for roughly 88% of IREN's total revenue, a complete inversion of the miner's historical mix in a single reporting period.

What does the backlog say about the business?

IREN's revenue backlog stood at $20.3 billion at quarter's end, up 22% from the prior quarter. Operating annual recurring revenue doubled to $1 billion. Both figures point to contracted, forward-looking demand rather than one-off hardware gains — the structural shift investors say they want from pivoting miners.

The quarter's centerpiece was operational: the first Microsoft data hall at IREN's Childress, Texas, site came online with NVIDIA GB300 systems. That hall anchors a five-year, $9.7 billion cloud services contract with Microsoft, the largest single commitment in the company's backlog.

Where did the quarter fall short?

The results weren't clean across the board. IREN posted a $263 million net loss, wider than analysts had projected. The company also pushed its target of more than $4 billion in annual recurring revenue into early 2027.

Management attributed the delay to two factors: a design change requested by Microsoft, and equipment delays at the Childress facility. IREN said the target remains fully contracted and fully funded — the constraint is execution timing, not demand.

Why is the mining decline not the story?

The drop in mining revenue, from $67 million to $28 million, reads less like a retreat and more like an allocation decision. IREN is deliberately shifting power and infrastructure capacity toward AI workloads, where gross margins of 86% and multi-year contracted backlog dwarf the economics of hash rate. At $228 million in total revenue against a shrinking mining base, the company has effectively become an AI infrastructure operator that still runs a mining sideline.

The operational consequence is significant: high-utilization, contracted AI compute replaces a volatile, commodity-exposed mining business as the primary cash-flow driver. The $1 billion in operating ARR and the $20.3 billion backlog give the company multi-year revenue visibility that Bitcoin mining cannot offer.

What comes next?

The near-term milestones are concrete. IREN must bring additional Microsoft data halls online at Childress to work down the equipment backlog and hit its revised ARR timeline. Every quarter of delay in reaching the $4 billion target extends the period during which the widened net losses persist against an otherwise high-margin revenue base.

Investors will watch the fiscal second quarter for two signals: whether AI cloud revenue continues compounding at anything near the prior quarter's 182% pace, and whether the Childress ramp stays on schedule after the design and equipment setbacks. With the Microsoft contract fully in place and funded, the story from here is delivery — scaling data halls fast enough to convert a $20.3 billion backlog into recognized revenue in early 2027.
