IREN announced partnerships with Microsoft and Nvidia for AI data center expansion, targeting $4.4B annual recurring revenue from AI capacity operations.

IREN (NASDAQ: IREN) is repositioning itself as a large-scale artificial intelligence data center builder and operator, moving well beyond its origins in cryptocurrency infrastructure. The company has signed new long-term infrastructure contracts with both Microsoft (NASDAQ: MSFT) and Nvidia (NASDAQ: NVDA), placing it at the center of surging global demand for AI compute capacity.

The most significant deal is a US$3.4 billion five-year AI cloud agreement tied to Nvidia's Blackwell GPUs. IREN is targeting US$4.4 billion in annual recurring revenue and is expanding its international data center footprint to add power and hosting capacity for a growing roster of AI-focused enterprise clients.

IREN's stock performance reflects the market's interest in the company's transformation. The stock closed at $47.21, with a year-to-date gain of 10.6% and a remarkable three-year increase of approximately nine times its earlier value. However, the stock has faced notable near-term pressure, falling 21.3% over the past week and 25.7% over the past month.

Vertical integration and preferred partner status with Nvidia form the backbone of IREN's strategy to grow recurring AI cloud revenues and develop power-efficient data centers at scale. Expansion of international power and hosting capacity places IREN alongside larger data center peers such as Equinix, Digital Realty, and CoreWeave as enterprises race to secure more AI compute.

Several risk factors merit investor attention. Long-term contracts with a concentrated group of hyperscale customers—specifically Microsoft and Nvidia—introduce meaningful counterparty and renewal risk. IREN still maintains exposure to Bitcoin mining alongside its AI workloads, meaning earnings remain sensitive to crypto price swings that can quickly shift investor sentiment. The company's heavy capital expenditure program, funded through debt, leases, and an at-the-market equity issuance program, raises questions about whether leverage and interest costs could outpace operating cash flow.

Going forward, investors will be watching how quickly IREN brings its planned GPU fleet and international data center sites online, and whether revenue ramps align with the US$4.4 billion ARR target. Funding terms for upcoming capital expenditure and any changes in contract scope with Microsoft and Nvidia will be critical indicators of whether the current build-out remains sustainable on the company's balance sheet.
