Once regarded as one of the largest bitcoin mining operations in North America, Core Scientific is now positioning itself as a significant player in AI infrastructure — and it’s securing $3.3 billion to make it happen.
On Tuesday, the company revealed plans to secure $3.3 billion via an offering of senior secured notes maturing in 2031. These notes will be collateralized by the company’s assets, providing bondholders with senior priority in the event of default. The financing strategy sidesteps equity dilution for current shareholders.
The capital raised will support active data center development projects and refinance outstanding short-term obligations, including amounts drawn under a 364-day credit line. Construction initiatives are underway in Georgia, Texas, North Carolina, and Oklahoma.
This isn’t Core Scientific’s inaugural major financing transaction in 2025. Back in March, Core Scientific finalized a $1 billion credit facility with Morgan Stanley. The current junk bond issuance complements that earlier arrangement.
Transition From Crypto Mining to AI Infrastructure
Established in 2017, the company became a prominent bitcoin mining operator before seeking Chapter 11 bankruptcy protection in December 2022. Elevated energy expenses combined with declining bitcoin valuations undermined profitability. The company exited bankruptcy in January 2024 and resumed trading on Nasdaq under the ticker CORZ.
Following the April 2024 halving event, mining rewards decreased from 6.25 BTC to 3.125 per block. Throughout late 2025, operational costs escalated while bitcoin’s value tumbled from above $125,000 to approximately $75,800. The economics became unsustainable for numerous mining operations.
However, miners possessed valuable infrastructure: operational data centers, established power agreements, and sites equipped with cooling systems. These resources aligned perfectly with the demands of AI companies.
Core Scientific entered into a capacity lease with CoreWeave through a 12-year arrangement. This contract is expected to generate around $10 billion in total revenue. Six AI-focused data centers are presently being developed to accommodate these computing requirements.
High-Yield Debt Market Powers AI Infrastructure Growth
Core Scientific represents just one player utilizing high-yield debt markets. Companies connected to AI infrastructure have collectively raised $17.9 billion through junk bond issuances this year, per Bloomberg data.
Notable transactions include $6.7 billion raised across offerings associated with Google-supported data centers and CoreWeave. Additionally, Edged Compute is currently marketing $1.3 billion in bonds for properties leased to CoreWeave and an Alibaba subsidiary.
CFO Jim Nygaard disclosed that the company maintains “under 1,000 bitcoin.” In March, Core Scientific liquidated $175 million in bitcoin holdings to support its strategic shift toward AI.
CORZ shares advanced approximately 6% during Tuesday’s session. Year-to-date, the stock has climbed nearly 42%, contrasting with an 11% decline in bitcoin over the same timeframe.
