🇺🇸Core Scientific (CORZ), historically a digital-asset miner, now derives most revenue from colocation; that segment remains concentrated with one customer.

Core Scientific’s November 5 Form 10-Q states that most company revenue now comes from its data-center services business. Historically, it mined digital assets for its own account and hosted third-party miners; its first contract with CoreWeave was announced in 2024, followed by contracts with AMD and a neocloud counterparty in July 2026.

The company retains three reportable segments: Colocation, Digital Asset Self-Mining, and Digital Asset Hosted Mining. Colocation supplies space, power, cooling, facilities operations, security, and other services for artificial intelligence and high-performance computing (HPC) workloads, rather than being described in the filing as a GPU rental business.

Reported lease revenue included in colocation revenue was $215.432 million for the third quarter of 2026, compared with $14.951 million a year earlier. For the first nine months, lease revenue was $429.640 million, versus $34.084 million in the comparable 2025 period; the filing explicitly states that colocation segment revenue is concentrated with a single customer.

As of September 30, Core Scientific operated a portfolio of 11 facilities: four in Texas, two in Georgia, and one each in Alabama, Kentucky, North Carolina, North Dakota, and Oklahoma. The newly signed AMD-related leases had not commenced at that date and had contributed no recognized lease revenue.
