Core Scientific (NASDAQ: CORZ) has paid $41.9 million to terminate a bitcoin miner contract with Block and its Proto unit, marking another step in the data center operator’s shift away from bitcoin mining and toward high-performance computing infrastructure for artificial intelligence workloads.
Deal Overview
The $41.9 million payment ends a previously agreed bitcoin miner arrangement between Core Scientific and Block’s Proto team, which oversees the company’s bitcoin mining hardware initiatives. Specific commercial terms of the original agreement were not disclosed. The termination removes a legacy obligation tied to bitcoin mining operations as Core Scientific reallocates resources to data center services supporting AI and other compute-intensive applications.
Strategic Pivot to AI Infrastructure
Core Scientific has been reorienting its business model to capture growing demand for AI-ready data center capacity. The company, historically one of the largest bitcoin miners in North America, has increasingly emphasized high-density, power-efficient hosting tailored for graphics processing units (GPUs) and other accelerators used in training and inference workloads. Exiting miner-related commitments aligns with that strategy by freeing power and rack space for higher-margin compute services.
Industry Context
The shift reflects broader changes across the digital infrastructure landscape. Following bitcoin’s 2024 halving, miners have faced tighter margins and more volatile economics, while demand for AI compute has surged. Several mining operators have diversified into high-performance computing to leverage existing power access, cooling, and facility footprints, seeking steadier revenue streams than those tied solely to block rewards and bitcoin price cycles.
About the Companies
Core Scientific is a U.S.-based data center operator and bitcoin miner that emerged from a court-supervised restructuring in 2024 and relisted on the Nasdaq. The company operates large-scale facilities designed for both blockchain and AI workloads.
Block, Inc. (NYSE: SQ), a financial technology company, runs Proto as its bitcoin mining hardware initiative. Proto focuses on developing open, modular bitcoin mining components and systems as part of Block’s broader bitcoin-focused projects.
What to Watch
Investors and industry participants will be watching how quickly Core Scientific can convert capacity from mining to AI hosting and the extent to which those deployments contribute to revenue growth and margin expansion. For Block, winding down the miner contract may streamline its hardware roadmap while it continues to develop and iterate on bitcoin mining technologies through Proto.
