Among all major Bitcoin miners, Core Scientific stands out as the most institutionally held company in the entire sector, with roughly 85% of its float owned by institutional investors. Vanguard controls about 10.95%, while BlackRock holds approximately 7.39%, making them two of the most influential stakeholders. This level of institutional concentration is unmatched and reflects a broader industry shift: Core Scientific — along with a handful of peers — is rapidly transitioning from traditional Bitcoin mining to hyperscale data center infrastructure designed for HPC and AI workloads. BlackRock’s involvement further reinforces the strategic relevance of this transformation.
