🔍Deep Dive Analysis
Iris Energy Limited was founded in Sydney, Australia, in 2018 by brothers Daniel and Will Roberts, who previously worked at Macquarie Group Ltd.. The company made its Wall Street debut on November 17, 2021, pricing its initial public offering (IPO) at $28 per share and raising approximately $231.5 million, with its shares trading on the Nasdaq Global Select under the ticker 'IREN'. The company initially positioned itself as a leading owner and operator of institutional-grade, highly efficient Bitcoin mining data centers powered by 100% renewable energy, primarily in British Columbia, Canada.
However, the company soon faced scrutiny. In December 2022, a class-action lawsuit was filed, alleging that the IPO offering documents were misleading. The complaint stated that certain Bitcoin miners owned through special purpose vehicles were unlikely to generate sufficient cash flow to service their debt obligations, leading to a significant drop in IREN's share price. This period highlighted the volatility inherent in the pure Bitcoin mining business model.
Recognizing the burgeoning demand for high-performance computing, Iris Energy began a strategic pivot in 2024, aggressively diversifying into AI cloud services. This transformation involved leveraging its existing data center infrastructure and access to low-cost renewable energy to host Graphics Processing Units (GPUs) for AI applications. A significant milestone in this pivot was the company's rebranding to IREN Limited in November 2024, reflecting its expanded focus beyond just Bitcoin mining.
Throughout 2025 and into 2026, IREN demonstrated rapid growth in its AI cloud segment. By September 2025, its AI Cloud capacity grew to approximately 23,000 GPUs, with projections of over $500 million in annualized run-rate revenue (ARR) by Q1 2026. A major turning point was securing a $9.7 billion multi-year contract with Microsoft for phased GPU deployments at its Childress, Texas, facility through 2026, with a 20% customer prepayment. This contract, along with other agreements, anchored its projected $3.4 billion in AI Cloud ARR by the end of 2026, with $2.3 billion already under contract.
As of April 15, 2026, IREN continues to expand its AI cloud capacity, announcing in March 2026 purchase agreements for over 50,000 NVIDIA B300 GPUs, expanding its total fleet to 150,000 GPUs. The company is also progressing with its Sweetwater 1 development in West Texas, targeting substation energization in Q2 2026, which will support further GPU deployments. Despite a recent earnings miss in February 2026, where the company reported a loss of $0.44 per share against an expected $0.07 loss, and revenue of $184.69 million against a $229.64 million consensus, Wall Street analysts generally maintain a 'Moderate Buy' consensus with an average price target of $70.08. The stock has experienced significant volatility, with a 52-week high of $76.87 and a low of $5.24, closing at $47.37 on April 14, 2026. IREN's strategic shift and substantial investments in AI infrastructure position it as a key player in the evolving high-performance computing landscape, leveraging its renewable energy assets.
