Core Scientific mining revenue halves, hosting business surges 268% to offset losses

Core Scientific (Ticker: CORZ), a Bitcoin mining hardware company, announced its Q4 2025 financial results, with total revenue dropping to $79.8 million. Hosting service revenue surged from $8.5 million to $31.3 million, an increase of over 268%, partially offsetting losses from mining operations, indicating that the company’s strategy to shift toward data center infrastructure is beginning to show initial results.

Q4 Financial Analysis: The Transformation Behind the Decline in Mining Revenue

Core Scientific’s revenue structure is undergoing a fundamental shift. Despite an overall decline in total revenue, gross profit for Q4 increased from $4.8 million in 2024 to $20.8 million, demonstrating that the profitability contribution from hosting services is improving. However, adjusted EBITDA remains negative at $42.7 million, reflecting short-term cost pressures during the transition. As of the end of last year, the company had $533.4 million in working capital, including $311.4 million in cash and cash equivalents, and Bitcoin holdings valued at $222 million. After the earnings release, Core Scientific’s stock slightly declined in after-hours trading.

1.5 GW Data Center Deployment: Core Scientific’s Long-term Strategic Bet

CEO Adam Sullivan stated, “We have completed over half of our current projects and expanded our hosting platform to 1.5 GW of leasable capacity. With a global presence and mature execution capabilities, we are accelerating the RFS (Ready for Service) progress at multiple sites to ensure sustainable growth for the company.”

This transformation is set against the backdrop of industry-wide challenges: as halving events reduce block rewards and competition for hashing power intensifies, pure mining profitability continues to narrow. Core Scientific is shifting its existing power and infrastructure assets toward high-density hosting services, catering to AI companies and other high-power computing clients.

Notably, in October last year, shareholders rejected a $9 billion all-stock merger proposal with AI computing company CoreWeave, although the two companies maintain a business relationship. This decision allows Core Scientific to continue its data center transformation as an independent publicly listed company. The subsequent execution results will be key for the market to assess whether its independent strategy can succeed.

Frequently Asked Questions

What is the main reason for Core Scientific’s Q4 2025 performance decline?

Bitcoin mining revenue fell from $79.9 million to $42.2 million, a decrease of nearly 47%, which is the primary reason for the overall revenue decline. Due to halving events reducing block rewards and increased competition for hashing power, the profit margins of pure mining operations continue to shrink.

Why did Core Scientific’s hosting service revenue increase significantly?

Core Scientific is actively leasing its infrastructure capacity to third parties, including AI companies with high-density computing needs. Hosting service revenue jumped from $8.5 million to $31.3 million, an increase of over 268%, reflecting the company’s core achievement in transforming into a data center business.

What is the outlook for Core Scientific after the merger proposal with CoreWeave was rejected?

After shareholders rejected the $9 billion merger proposal last October, Core Scientific continues to operate as an independent company, focusing on expanding its hosting platform to 1.5 GW of leasable capacity. The two companies still maintain a business relationship, but the market will closely scrutinize Core Scientific’s ability to execute its independent strategic plan.
