IREN Limited
IREN Limited operates as a vertically integrated AI cloud services platform in Australia and Canada. It develops, owns, and operate data centers, including the associated land, grid connections, and substations, as well as buildings and cooling. The company also owns and operates compute layers, such as GPUs, CPUs, storage, servers, and networking deployed within that data center infrastructure; and software layers comprising managed services and enterprise support that enables customers to deploy, operate, and manage AI workloads. In addition, it is involved in Bitcoin mining. The company was formerly known as Iris Energy Limited and changed its name to IREN Limited in November 2024. IREN Limited was incorporated in 2018 and is based in Sydney, Australia.
What does it do?
IREN Limited runs large data centers in Australia and Canada that are packed with powerful computers doing two things: mining Bitcoin and providing computing power for AI workloads. Think of Bitcoin mining like a global lottery where computers compete to solve puzzles and win Bitcoin as a reward — IREN runs thousands of machines playing that lottery 24/7. The company builds and owns everything itself: the buildings, the electrical systems, and the actual computers. It was previously called Iris Energy and rebranded in late 2024 to reflect its push beyond just Bitcoin.
IREN sits at the crossroads of two of the hottest investment themes right now: Bitcoin and artificial intelligence infrastructure. As Bitcoin crossed major price milestones and AI companies scrambled for computing power, companies like IREN that own physical data center capacity became suddenly very valuable. The rebranding from Iris Energy to IREN signals a deliberate pivot toward AI cloud computing, which investors see as a potentially bigger and more stable business than Bitcoin mining alone.
How does it make money?
IREN makes money primarily by mining Bitcoin — their computers run constantly, earn Bitcoin, and the company sells that Bitcoin for cash. Revenue jumped from $0.2 billion to $0.5 billion in a single year, which is a 150% increase, largely driven by rising Bitcoin prices and more mining machines coming online. The company is also beginning to sell spare computing capacity to AI and cloud customers who need serious processing power. Their net income was $0.1 billion, meaning they kept roughly 20 cents of profit for every dollar earned.
Why do investors care?
The growth story here is essentially a bet on two things going right at once: Bitcoin staying valuable and AI demand for computing power continuing to surge. IREN has a competitive edge because it sources cheap, often renewable energy — lower electricity costs mean more profit per Bitcoin mined. If the company successfully transitions a meaningful chunk of its capacity to AI cloud services, it could earn steadier, contract-based revenue rather than depending entirely on volatile Bitcoin prices. Investors are essentially getting exposure to both crypto and AI infrastructure in one stock.
