Black Pearl Compute, an AI subsidiary of Cipher Mining, has drawn exceptional demand in its $2 billion junk bond sale. The deal, launched on February 2, 2026, attracted $13 billion in orders, reflecting strong investor interest. The capital raised will help fund the development of a new data center in Texas, part of a lease agreement with Amazon Web Services (AWS).
Investor Demand Surpasses Expectations
The strong interest in Black Pearl’s bond offering comes at a time when cryptocurrency mining firms are diversifying into high-performance computing, especially AI infrastructure. The sale was priced to yield 6.125% for a five-year bond. According to Bloomberg, bonds in the BB junk bond range typically yield an average of 5.56%. The oversubscription by $11 billion indicates substantial demand for financing in the AI sector.
Black Pearl’s parent company Cipher Mining will use the proceeds for various corporate needs. This includes reimbursing Cipher for earlier equity investments in Black Pearl Compute and securing funds for its broader AI infrastructure projects. This move comes as mining firms like Cipher pivot to more lucrative opportunities in AI and high-performance computing.
Funding Will Support AWS-Leased Data Center
A significant portion of the bond sale’s proceeds will go toward constructing the Black Pearl data center, leased to AWS for at least 15 years. The deal, valued at approximately $5.5 billion in contracted revenue, covers 300 MW of capacity. The agreement with AWS, announced in November 2025, is crucial for Black Pearl’s long-term financial strategy and expansion.
The data center’s scale is expected to support growing demand for AI-driven services. As the AI industry requires powerful infrastructure, partnerships with major tech players like AWS are vital for securing substantial revenue. The lease agreement with AWS ensures long-term stability for Black Pearl’s business model and its ability to attract investment.
Rising Demand for AI Infrastructure in the Mining Sector
The strong demand for Black Pearl Compute’s bonds is part of a broader trend where mining firms are leveraging their existing infrastructure to build out AI projects. This trend is not unique to Cipher Mining. For example, TeraWulf and Galaxy Digital have also raised significant debt to support AI-focused projects in the past year. Cipher’s move mirrors this shift as mining companies adapt to the booming AI market.
As high-performance computing continues to grow in demand, miners are positioning themselves to serve these needs. With global AI infrastructure expected to expand rapidly in the coming years, the ability to secure substantial financing is critical for companies like Cipher and Black Pearl Compute.
Despite a 12.36% drop in Cipher’s stock price, the bond sale’s success demonstrates confidence from investors in the company’s future prospects in AI. Investors seem to be placing a bet on the continued demand for AI-powered data centers, as evidenced by the overwhelming response to Black Pearl’s latest offering.
