Better AI Infrastructure Stock: Nebius Group vs. Iren Limited

Projected multitrillion-dollar demand for AI infrastructure is driving rapid expansion in GPU-powered data centers, and two contrasting plays are Nebius Group and Iren Limited. Nebius (formerly Yandex N.V.) is scaling fast—Q3 revenue $146.1m, up 355% YoY—and has won large deals including a potential $19.4bn pact with Microsoft and a $3bn, five‑year arrangement with Meta, but remains unprofitable (Q3 net loss $100.4m; YTD losses $273.7m) as it invests in up to 1–2.5 GW of power capacity. Iren is profitable today because Bitcoin-mining revenue drove Q1 FY2026 revenue of $240.3m (+335% YoY) and net income $384.6m while it builds AI capacity—signing a $9.7bn Microsoft cloud services deal, ordering $5.8bn of Dell GPUs/equipment and planning 140k GPUs—although AI revenue is currently nascent; the author favors Iren for its profitability and lower leverage amid the capital- and obsolescence-intensive nature of AI data centers.

Analysis

Industry demand for AI infrastructure is being framed as a multitrillion-dollar opportunity, with Nvidia’s CEO estimating $3 trillion–$4 trillion of spend on AI infrastructure and data centers by 2030; that backdrop explains why GPU-heavy data-center plays are scaling aggressively. Nebius (formerly Yandex N.V.) reported Q3 revenue of $146.1 million, up 355% year-over-year, and has secured large customer agreements including a potential up-to-$19.4 billion Microsoft deal and a $3 billion, five-year Meta contract, but it remains unprofitable with a Q3 net loss of $100.4 million and year-to-date losses of $273.7 million as it ramps capacity. Iren Limited reported Q1 FY2026 revenue of $240.3 million, up 335% year-over-year, and turned to net income of $384.6 million versus a prior-year loss of $51.7 million, driven by $232.9 million of Bitcoin-mining revenue while AI cloud revenue was $7.3 million; it also signed a $9.7 billion Microsoft cloud services deal and plans to buy $5.8 billion of GPUs/equipment from Dell. The investment trade-off is clear: Nebius offers high growth exposure tied to large cloud contracts but with ongoing cash burn and buildout risk (targeting 1–2.5 GW of power), while Iren delivers current profitability funded largely by crypto revenue but with AI revenue still nascent; both face GPU obsolescence and capital intensity that will determine long-term returns.

Key Decisions for Investors

• Favor Iren for a core position if seeking nearer-term profitability and lower leverage given Q1 FY2026 net income of $384.6 million and the company’s disclosure that Bitcoin-mining revenue currently funds its expansion
• Treat Nebius as a higher-risk, growth-oriented satellite position sized for volatility until it demonstrates sustained profitability or meaningful free-cash-flow generation given Q3 net loss of $100.4 million and YTD losses of $273.7 million
• Monitor three near-term indicators before increasing exposure: realization and revenue recognition of the Microsoft and Meta contracts, contracted GW and data-center utilization metrics, and trends in GPU refresh cycles/CapEx requirements
• Use disciplined position sizing or hedges to limit downside from execution risk and rapid GPU obsolescence, and reassess allocations if AI revenue mix or cash-burn trajectories materially change
