Core Scientific is set to launch a $3.3 billion junk bond offering as part of its strategic shift towards AI-driven data center operations. The surge in demand for AI services has put a strain on data centers, power supply, and advanced chip technology, prompting firms to explore riskier debt markets to fund their operations. Core Scientific, formerly a bitcoin mining company, recently sold $175 million in bitcoin to further its AI-focused transition.

Borrowers associated with AI infrastructure have raised a total of $17.9 billion in junk bonds this year, according to Bloomberg. Core Scientific is developing six data centers designed to support AI workloads, with a 12-year leasing agreement with CoreWeave that could generate around $10 billion in revenue. This move follows a series of large-scale deals, including recent offerings tied to Google-backed data centers and CoreWeave, which collectively raised $6.7 billion. Another company, Edged Compute, is currently marketing $1.3 billion in bonds to fund facilities leased to CoreWeave and an Alibaba subsidiary.

Core Scientific intends to utilize the proceeds to repay existing debt, fund reserves, and support construction across multiple states if costs exceed available funds, highlighting the capital-intensive nature of AI development. The company currently holds fewer than 1,000 bitcoin, according to CFO Jim Nygaard.

Core Scientific's pivot from bitcoin mining to AI hosting is driven by the pursuit of higher margins. The company's transition began after filing for Chapter 11 in December 2022, due to high power costs and a decline in bitcoin prices. It emerged from reorganization in January 2024 and was relisted on Nasdaq under the ticker CORZ. The shift from bitcoin mining to AI hosting is centered around maximizing profitability, as the average cash cost to mine one bitcoin increased while the price of BTC itself declined.

With rising power costs and intense competition, most miners became unprofitable, prompting them to explore alternative revenue streams. The emergence of AI has provided a new use case for miners' existing assets, including data centers and power contracts, which are now being utilized to host AI-powered computers. Core Scientific was one of the first mining companies to pivot towards AI on a large scale, capturing the attention of investors and sparking the AI-driven push. The company's shares have seen a significant increase, with a 6% rise on Tuesday and a 42% gain this year, while bitcoin prices have fallen by 11%.
