IREN builds and runs large data centres powered by renewable energy, at sites in Texas and British Columbia. It rents out Nvidia GPUs as an AI cloud for training and running AI models, and uses the rest of its capacity to mine bitcoin.
It began as a bitcoin miner built around cheap renewable power, and has shifted towards AI, including a multi-year AI cloud contract with Microsoft announced in 2025.
Brothers Daniel and Will Roberts founded the company in Sydney in 2018 as Iris Energy. It listed on the Nasdaq in 2021 and renamed itself IREN in 2024.

Why I own it
The limit on AI isn't only chips, it's electricity. IREN owns renewable-powered sites with large grid connections in Texas and British Columbia, and it's turning them from bitcoin mining into AI cloud.
Power and land ready for data centres take years to secure. IREN already has them, which puts it ahead of anyone starting from scratch. It's volatile and capital hungry, which is the price of owning a scarce asset early.

IREN falls 42pc from its high even as revenue jumped 41pc
IREN shares are down 45.4% from their 52-week high and slid another 11.7% this week. The FY26 results on 27 August showed revenue up 41% to $707 million but a $684 million net loss and a warning of $25-30 billion in 2027 capex. Analysts at Redburn then started the neocloud group at Neutral, dragging IREN down with CoreWeave and Nebius even as JPMorgan raised its own target to $65.
Since this note:IREN −14.4%(S&P 500 +1.1%)
