Core Scientific increased its Bitcoin holdings in the second quarter, reversing part of this year’s decline. In a Tuesday regulatory filing, the Nasdaq-listed miner said it held 848 Bitcoin, worth more than $54 million at current prices.

The company ended the first quarter with 547 Bitcoin, meaning it added 301 coins during the second quarter. Most of those Bitcoin came from production through mining.

Core Scientific Rebuilds Its Bitcoin Treasury

Core Scientific finished 2025 with 2,537 Bitcoin, but sold a large share of its holdings during the first quarter. The company used those sales to support its expansion into artificial intelligence and high-performance computing services.

The miner has now begun retaining more of the Bitcoin it produces. That approach gives Core Scientific a larger digital asset reserve while supporting its balance sheet without relying solely on new shares or debt. For publicly traded miners, the mix of self-mined Bitcoin, treasury management, and outside financing has become a key part of how they navigate a business shaped by network difficulty, energy costs, and capital-intensive infrastructure.

Core Scientific reported second-quarter revenue of $164.2 million, up from $78.6 million in the same period a year earlier. Gross profit rose to $70 million from $5 million in the second quarter of 2025.

CORZ shares traded about 2% lower on Tuesday afternoon in New York. Core Scientific operates data centers in Alabama, Georgia, Kentucky, North Carolina, North Dakota, Oklahoma, and Texas.

AMD Deal Expands AI Data Center Business

Core Scientific also signed a data center agreement with AMD covering 2.5 gigawatts of capacity. The deal will give AMD access to more than 500 megawatts of AI-ready capacity.

The agreement supports Core Scientific’s shift into AI and high-powered computing. The company is using its existing power access and data center sites to serve customers that need large amounts of computing capacity, a strategy that has drawn attention across the mining sector as firms look to monetize their infrastructure beyond block rewards alone.

Several public Bitcoin miners are expanding into AI infrastructure as mining becomes more difficult and demand for computing power grows. Many companies now combine Bitcoin mining with data center services rather than focusing only on mining.

This model allows miners to direct power and equipment toward businesses with stronger returns. However, AI data centers require more advanced cooling, ventilation, and facility systems than standard Bitcoin mining sites.
