IREN's AI Cloud Just Overtook Bitcoin Mining — Now Comes the Hard Part

IREN's AI cloud revenue now 51.4% of sales, but $684M loss and capex plan spook investors, sending shares down 12%.

For the first time in its corporate history, IREN is no longer primarily a crypto miner. The company's fourth-quarter results delivered the long-promised inflection point: AI cloud revenue now accounts for 51.4 percent of total sales, edging past the Bitcoin mining business that built the firm. Yet the milestone arrived wrapped in a $684 million net loss and a revenue miss that sent shares tumbling — a reminder that transformation, however strategically sound, rarely comes cheap.

The market's reaction was swift and unforgiving. IREN shares fell 12 percent on Friday and 14 percent over the trailing seven-day stretch, leaving the stock 55 percent below its 52-week high of €68.61 set in early November. The sell-off wasn't isolated: CoreWeave dropped 6.8 percent on Wednesday, Nebius Group shed 5.2 percent, and TeraWulf fell 6.5 percent. When the entire "neocloud" complex wobbles, the most indebted names tend to wobble hardest.

A Loss That Tells a Story of Transition

The headline numbers look grim at first glance. IREN posted a net loss of $684 million for the fourth quarter, with the bulk stemming from a $638.8 million impairment charge on older mining hardware. The secondary source pegs that write-down at $450.4 million — either way, the message is identical: the company is clearing the decks of its legacy Bitcoin equipment to make room for the AI infrastructure business it believes will define its future.

The operating picture beneath the red ink is more nuanced. The quarterly loss per share came in at 41 cents, beating the 50-cent consensus estimate. Revenue, however, told a different story: $137.2 million fell well short of the $157.14 million analysts had penciled in. Adjusted EBITDA also took a hit, sliding from $59.5 million to $19.2 million quarter over quarter.

The revenue mix is where the strategic narrative comes into focus. AI cloud revenue surged 110 percent sequentially to $70.5 million, now representing just over half of total sales. Bitcoin mining revenue, meanwhile, contracted from $111.2 million to $66.7 million. The crossover has been telegraphed for quarters — now it's a fact on the ledger.

A $30 Billion Bet Against a $12 Billion Market Cap

Anyone expecting the company to hit the brakes after the earnings reset will be disappointed. IREN has guided to capital expenditures between $25 billion and $30 billion for the coming fiscal year — a figure that dwarfs its current market capitalization of roughly €12.18 billion. The balance sheet shows $7.6 billion in cash as of June 30, though $1.7 billion of that is restricted.

Management's counterargument rests on a growing contracted revenue base. The annualized recurring revenue contracted for 2026 now stands at $4 billion, up from $3.4 billion in July — and recently raised from $3.7 billion, with about 85 percent already under contract and a quarter operational. The company also delivered its first 50-megawatt liquid-cooled deployment to Microsoft last Thursday and achieved "Nvidia Exemplar Cloud" status for its GB300-NVL72 platform. The $625 million all-stock acquisition of Mirantis, completed about a week ago, is meant to strengthen the software layer underpinning the cloud offering.

The gap between capital requirements and contracted revenue is the crux of investor anxiety. It's the classic infrastructure-transition dilemma: can a company sign up customers fast enough to justify the billions it's spending today, before financing costs or market sentiment turn against it?

Analysts Split Down the Middle

Wall Street remains divided on the answer. H.C. Wainwright reaffirmed its Buy rating with a $90 price target on Friday, leaning visibly on the growth side of the ledger. JPMorgan's Richard Choe, by contrast, reiterated his Sell stance with a $46 target on Thursday, pointing to uncontracted GPU capacity and elevated leverage as central risks.

The broader market backdrop hasn't helped. Long-dated Treasury yields hit a 19-year high, reports surfaced of Anthropic and OpenAI revenue coming in below expectations, and the Wall Street Journal detailed roughly $3 trillion in off-balance-sheet AI commitments across the industry. When refinancing costs rise and demand questions mount simultaneously, every provider of compute capacity feels the squeeze — IREN just feels it more acutely than most.

The stock's trading range tells its own story: 62 percent above the August 28 low, 55 percent below the November 3 peak, with 30-day annualized volatility of 125 percent. That's not a chart for the faint-hearted. It's the signature of a market that hasn't decided whether IREN is building the future of AI infrastructure — or overextending itself in the process.

The question hanging over the company is the same one facing every crypto-miner-turned-cloud-provider: will the expensive metamorphosis produce a sustainable business before the capital runs out? At IREN, that answer remains unwritten — but each quarterly report makes the stakes clearer.
