CoreWeave stock plummeted 14.4% after investor Chamath Palihapitiya posted a chart showing the company's bond yield reached 15%, up from 9% in summer. The surge reflects concerns about CoreWeave's $35 billion debt burden and its reliance on borrowing to fund chip and data center investments. Rising interest rates pose a significant threat to the company's profitability, though it continues to show strong revenue growth.

IREN Limited is expanding its AI data center infrastructure globally with a 5GW development pipeline across North America, Europe, and Australia. The company targets 300MW of commissioned capacity by end-2026 and 800MW by end-2027, with $4 billion in contracted annualized revenues. However, the company faces significant capital expenditure requirements of $25-30 billion for fiscal 2027 and has seen recent stock underperformance with downward earnings revisions.

Iren, an AI cloud and data center operator, closed down 1.11% at $34.80 on October 12, 2026, after early reports of a multiyear cloud services agreement with Anthropic. The company continues its pivot from cryptocurrency mining to AI cloud infrastructure, with AI Cloud Services revenue increasing eightfold year-over-year. Trading volume surged 13% above average as investors monitor AI infrastructure demand and capacity monetization.

An analyst sold Cipher Digital shares to increase positions in Iren, citing Iren's superior per-megawatt contract values, larger pipeline (5.8 gigawatts), and faster capacity deployment (500 MW in 2027 vs. Cipher Digital's 270 MW). Rising megawatt prices and customer prepayments are expected to help Iren offset capital intensity and dilution concerns.

IREN Limited is developing the Sweetwater campus as a significant AI infrastructure platform with planned 2 GW gross power capacity across two phases. The company aims to replicate Sweetwater's liquid-cooled design across future projects, with recent AI contracts generating $20-25 million per IT MW. However, execution depends on capital availability, ERCOT grid access, and converting planned capacity into operational revenue. IREN trades at a premium valuation and recently saw downward earnings revisions.

SpaceX launched a test satellite with Google's TPUs to explore orbital data centers, but satellite-based data centers will cost 2.5-3x more than Earth-based facilities. Tech giants need computing power immediately and are investing heavily in neocloud companies like Nebius and Iren, which have available megawatt capacity and scaling pipelines. Orbital data centers are unlikely to replace terrestrial data centers in the near term.

IREN Limited is experiencing significant improvements in its infrastructure business with three-year contracts signed above $20 million per MW and discussions reaching $25 million. Pricing has increased 125% for three-year contracts and 70% for five-year contracts since November 2025. Customer prepayments covering 45-55% of GPU capex and potential spare power deployment are improving project economics. However, execution remains critical as the company commissions new capacity.

As hyperscalers invest heavily in data center infrastructure to support AI services, with Morgan Stanley projecting $1.4 trillion in capital spending by 2028, two data center stocks offer attractive valuations: Iren, which is building an AI cloud platform with vertically integrated capabilities and targeting $4 billion revenue by 2026, and Vertiv, which supplies power management and cooling systems to data centers with projected 20-22% annual revenue growth through 2030.

The article compares two AI infrastructure companies: Applied Digital (APLD) and IREN (IREN). Applied Digital shows stronger margins (22.38% vs 9.84%) and lower P/S ratio (13.1x vs 23.0x) but faces customer concentration risk with CoreWeave. IREN has secured major contracts with Microsoft ($9.7B) and Nvidia ($3.4B) and is pivoting from crypto mining to AI cloud services, though it reported a massive net loss of $702.6M. The author recommends IREN for patient investors due to its stronger contracted revenue base and blue-chip customer relationships, despite both companies currently losing money.

IREN Limited is diversifying its AI cloud customer base away from heavy dependence on Microsoft and NVIDIA by signing $2.8 billion in contracts with Prometheus, Perplexity, and Together AI in July 2026. The company is experiencing stronger contract economics with three-year pricing up 125% and five-year pricing up 70%, though it faces risks from early-stage customers and shorter contracts. With 2026 capacity largely sold out, IREN is targeting broader customer expansion for 2027-2028.

NVIDIA announced a major expansion of AI infrastructure in Australia through partnerships with local cloud providers and infrastructure companies including Firmus, Sharon AI, IREN, Megaport, ResetData, CDC, NEXTDC, and AirTrunk. The collaboration aims to deliver up to 2 gigawatts of capacity by 2027 using NVIDIA's DSX platform to support growing AI demand from startups, enterprises, and research organizations across the region.

Applied Digital (APLD) has declined 35.6% over three months, significantly underperforming peers and the broader market. The company faces heavy capital requirements ($2.87B spent in fiscal 2026), rising leverage ($5.31B in debt obligations), and delayed revenue realization as most contracted capacity won't become operational until 2027-2028. Earnings estimates have been revised downward, and the stock trades at a premium valuation relative to peers. Zacks recommends selling due to unfavorable risk-reward dynamics.
