Core Scientific's AI hosting agreement with CoreWeave is delivering an impressive average return on assets (ROA) of 75% and a cost yield of 79% over five years, according to Bernstein analysis. This high return is attributed to Core Scientific's unique capital expenditure structure, which is not easily replicable by other firms. In contrast, typical ROA for companies like TeraWulf, Cipher, and CleanSpark ranges from 4% to 5%, with cost yields between 17% and 19%, aligning more closely with industry norms. Bitcoin miners have shifted approximately 7 GW of power to supercomputing, cloud, and chip companies over the past two years, entering into 19 AI infrastructure hosting contracts valued at over $135 billion. Despite this trend, high-return projects like those of Core Scientific and Riot remain scarce due to their specialized capital structures.
