Core Scientific Seeks $3.3 Billion Bond Sale to Fund AI Data Center Pivot

Core Scientific is preparing to raise $3.3 billion through a junk bond sale as it continues its transition from bitcoin mining toward artificial intelligence-focused data center operations.

The company, once one of North America's largest bitcoin miners, is building six AI data centers that will support AI workloads. The capacity is leased to CoreWeave under a 12-year agreement that could generate approximately $10 billion in revenue.

Demand for AI services has pushed data centers, power supplies, and advanced chips to their limits. To keep up, firms are tapping riskier parts of the debt market for funds to continue developing their operations. Core Scientific itself sold $175 million in bitcoin last month to further its AI pivot.

In Brief

• Core Scientific (CORZ) is raising $3.3 billion via a junk bond sale to finance its shift from crypto mining to AI-focused data centers.
• The company is building six AI data centers leased to CoreWeave for 12 years, expected to generate ~$10 billion in revenue.
• This high-yield debt issuance is part of $17.9 billion raised in AI infrastructure junk bonds so far this year.
• Proceeds will fund construction costs, repay existing debt, and build reserves.
• The company still holds "under 1,000 bitcoin" , down significantly from its previous holdings.

From Bitcoin Mining to AI Hosting

Core Scientific was founded in 2017 and grew into one of North America's largest bitcoin miners before filing for Chapter 11 bankruptcy in December 2022, squeezed by high power costs and a weak bitcoin price. It emerged from reorganization in January 2024 and was relisted on Nasdaq under the ticker CORZ.

The pivot from bitcoin mining to AI hosting is all about the margins.

The April 2024 halving cut block rewards from 6.25 BTC to 3.125 BTC. By late 2025, the average cash cost to mine one bitcoin had risen while the price of BTC itself had been on a downturn, falling from over $125,000 to around $75,800. With rising power costs and intense competition, most miners became unprofitable and had to find alternative ways to continue earning revenue.

That is when AI came to the rescue. Miners' most valuable assets — already-built data centers and power contracts — gained a new use case: hosting computers that power artificial intelligence.

The AI Bond Rush

Borrowers linked to AI infrastructure have raised $17.9 billion in junk bonds so far this year, according to Bloomberg. Core Scientific's move follows a string of large deals. Recent offerings tied to Google-backed data centers and CoreWeave raised a combined $6.7 billion. Another firm, Edged Compute, is marketing $1.3 billion in bonds to fund facilities leased to CoreWeave and an Alibaba unit.

Core Scientific said it will use the proceeds from its $3.3 billion bond sale to:

• Repay existing debt
• Fund reserves
• Support construction across several states if costs exceed available funds

This underscores just how capital-intensive the AI buildout has become.

Why AI Companies Want Mining Facilities

Bitcoin miners' power contracts, grid connections, and cooling-ready sites have become highly attractive to hyperscalers — including Microsoft, Google's parent Alphabet, and others in the ongoing AI race.

Core Scientific was one of the first miners to pivot on a large scale, which caught investors' attention and sparked the broader AI push among crypto mining companies.

The Numbers

Market Reaction

Core Scientific's shares were up about 6% on the day of the announcement and are up nearly 42% year-to-date. In contrast, bitcoin has fallen 11% over the same period.

That divergence tells the story. Investors are rewarding the pivot away from pure crypto mining and toward the booming AI infrastructure sector. The market sees AI hosting as a more stable, predictable, and profitable business model than bitcoin mining, which remains subject to volatile energy prices, fluctuating bitcoin prices, and recurring halving events.

What This Means for the Crypto Mining Industry

Core Scientific's move is not an isolated case. Other miners are following similar paths:

• Hut 8 has been diversifying into AI hosting
• Iris Energy is expanding its data center capabilities
• Applied Digital is pivoting toward high-performance computing

The trend suggests that the bitcoin mining industry is at a crossroads. Miners with access to cheap power and existing infrastructure have a valuable asset that AI companies are willing to pay for. Those without may struggle to survive.

The April 2024 halving made mining less profitable for many. The combination of reduced block rewards, rising energy costs, and a volatile bitcoin price has pushed miners to seek alternative revenue streams. AI hosting offers higher margins and longer-term contracts, making it an attractive option.

What Remains of Core Scientific's Bitcoin Holdings

Chief Financial Officer Jim Nygaard confirmed that the company still holds "under 1,000 bitcoin" . That is a significant reduction from its previous holdings, as the company sold $175 million in bitcoin last month to fund its AI pivot.

The remaining bitcoin is a fraction of what Core Scientific once held, reflecting the company's strategic shift away from accumulating crypto on its balance sheet and toward building recurring revenue from AI infrastructure.

Final Summary

Core Scientific, once one of North America's largest bitcoin miners, is raising $3.3 billion through a junk bond sale to finance its transition toward AI-focused data center operations. The company is building six data centers leased to CoreWeave under a 12-year agreement expected to generate approximately $10 billion in revenue.

The pivot reflects a broader trend of bitcoin miners repurposing their power contracts, grid connections, and cooling-ready facilities to host AI computers. Demand for AI services has pushed infrastructure to its limits, and miners are tapping riskier parts of the debt market to fund the capital-intensive buildout.

Core Scientific's shares are up 42% year-to-date, while bitcoin has fallen 11% over the same period. The company still holds "under 1,000 bitcoin," down significantly from its previous holdings.
