Crusoe Energy, which operates modular, energy-efficient data centres for AI compute, is raising about $1.38 billion in its latest funding round to scale capacity and plant deployments. The Denver-based firm combines energy optimisation with chip-level hosting to provide flexible compute for model training. Crusoe plans to use proceeds for international expansion and to deepen partnerships with hyperscalers and enterprise customers. The raise underscores investor appetite for specialised AI data-centre capacity amid surging demand for efficient training infrastructure.
