Iris Energy said it has ordered 2,400 of Nvidia’s new-generation Blackwell graphics processing units for roughly $130 million, deepening the bitcoin miner’s push into providing cloud computing capacity for artificial-intelligence developers. The deal will lift Iris Energy’s total GPU fleet to about 4,300 units once the hardware is delivered and installed, expanding the company’s AI-focused infrastructure alongside its existing data-center and renewable-powered mining operations. Investors welcomed the move: the stock jumped about 15% in early New York trading to a 52-week high of $18.18, extending a recent rally driven by growing demand for high-performance compute capacity.
