Data-center operator IREN Limited said it has bought 4,200 Nvidia Blackwell B200 graphics-processing units for about $193 million, doubling its fleet to roughly 8,500 GPUs. The new hardware will be installed at the company’s 50-megawatt Prince George campus, expanding IREN’s AI Cloud capacity to meet rising demand for high-performance computing. Separately, the company secured $102 million in financing for an earlier purchase of Nvidia Blackwell B200 and B300 chips. The funding, structured as a 36-month lease at a high single-digit interest rate, frees up cash for additional growth initiatives, including potential further GPU acquisitions. IREN said the latest expansion will not affect its bitcoin-mining operations, which remain at about 50 exahashes per second. Co-CEO Daniel Roberts asserted that the enlarged Blackwell fleet positions the firm to capture stronger AI Cloud revenue while maintaining a capital-efficient balance sheet.
