- Core Scientific (CORZ) plans to secure $3.3B via a junk bond offering to support AI data center infrastructure development.
- The financing involves senior secured notes maturing in 2031, with company assets serving as collateral.
- The company is constructing six AI-focused data centers under a 12-year CoreWeave lease expected to generate approximately $10B in total revenue.
- CORZ shares climbed roughly 6% on Tuesday and have gained nearly 42% since the start of the year.
- This capital raise comes after the company secured a $1B credit facility with Morgan Stanley in March.
Core Scientific once ranked among North America’s largest bitcoin mining operations. Today, the company is pivoting aggressively toward AI infrastructure — and it’s raising $3.3 billion to make that transformation happen.
On Tuesday, the company unveiled plans to issue $3.3 billion in senior secured notes with a 2031 maturity date. These notes will be collateralized by Core Scientific’s physical assets, providing bondholders with preferential claims should a default occur. Importantly, this debt structure allows the company to raise capital without diluting current shareholders.
The funds raised will finance ongoing data center construction projects and retire existing short-term obligations, including amounts drawn under a 364-day revolving credit facility. Construction sites span multiple states including Georgia, Texas, North Carolina, and Oklahoma.
This isn’t the company’s inaugural large-scale financing initiative in 2025. Earlier in March, Core Scientific secured a $1 billion credit facility arranged by Morgan Stanley. The newly announced junk bond issuance supplements that earlier funding.
Transformation from Crypto Mining to AI Infrastructure
Established in 2017, the company rapidly ascended to become one of the premier bitcoin mining operators before declaring Chapter 11 bankruptcy protection in December 2022. Escalating electricity expenses combined with depressed bitcoin valuations created an unsustainable business model. The company successfully exited bankruptcy proceedings in January 2024 and resumed trading on the Nasdaq exchange under the ticker CORZ.
The April 2024 bitcoin halving event reduced mining rewards from 6.25 BTC to 3.125 BTC per block. Throughout late 2025, operational costs continued rising even as bitcoin’s price declined from peaks above $125,000 down to approximately $75,800. This economic pressure made traditional mining increasingly unprofitable for most operators.
However, miners possessed valuable infrastructure: fully developed data center facilities, existing power purchase agreements, and sites engineered for thermal management. These physical assets proved highly attractive to artificial intelligence companies seeking computing capacity.
Core Scientific negotiated a capacity lease arrangement with CoreWeave spanning 12 years. This agreement is forecast to generate approximately $10 billion in cumulative revenue. Six purpose-built AI data centers are presently under development to fulfill these contractual obligations.
High-Yield Debt Markets Accelerating AI Infrastructure Investment
Core Scientific represents just one player accessing high-yield debt markets for AI infrastructure financing. Companies connected to AI data center development have collectively raised $17.9 billion through junk bond offerings year-to-date, based on Bloomberg data.
Recent transactions include a combined $6.7 billion raised through bond sales associated with Google-supported data centers and CoreWeave facilities. Additionally, Edged Compute is currently marketing $1.3 billion in bonds to finance properties leased to CoreWeave and an Alibaba subsidiary.
CFO Jim Nygaard disclosed that the company currently maintains a bitcoin treasury position of “under 1,000 bitcoin.” In March, the firm liquidated $175 million in bitcoin holdings to partially finance its strategic pivot toward AI infrastructure.
CORZ shares appreciated approximately 6% during Tuesday’s trading session. The stock has delivered gains of nearly 42% year-to-date, substantially outperforming bitcoin, which has declined 11% over the identical timeframe.
