Cipher Mining Inc. (NASDAQ: CIFR) has significantly expanded its private offering of convertible senior notes, raising the total value from $800 million to $1.1 billion, following a landmark 10-year, $3 billion AI hosting agreement with Fluidstack. The deal, backed by Google’s $1.4 billion financial guarantee and a 5.4% equity stake in Cipher, marks a strategic pivot for the fifth-largest public Bitcoin miner into high-performance computing (HPC) and AI infrastructure.

The upsized offering includes $1.1 billion in convertible senior notes due 2031, with an additional $200 million in purchase options. Proceeds will fund the development of Cipher’s Barber Lake facility in Texas, which will deliver 168 megawatts of critical IT load capacity by September 2026. The facility, expandable to 500 MW, is part of a broader 2.4 gigawatt pipeline prioritized for HPC. Google’s backstop ensures Fluidstack’s lease obligations, while its warrants for 24 million shares (5.4% pro forma ownership) align with Cipher’s goal to leverage capital markets for project financing.

The Fluidstack agreement includes two five-year renewal options, potentially extending the deal’s value to $7 billion. Cipher’s CEO Tyler Page emphasized the transaction as “transformative,” citing the company’s growing HPC momentum and the first of several anticipated partnerships in the sector. The deal also underscores Google’s strategy of securing AI infrastructure through third-party hosting providers, a model previously employed in its August 2025 agreement with TeraWulf.

Market reaction to the announcements was mixed. Cipher’s shares surged 20% in pre-market trading but closed 17.5% lower amid broader market volatility. Analysts attribute the fluctuation to investor caution following the stock’s sevenfold rise since April 2025. The company’s financials reflect this shift: Q2 2025 revenue was $44 million, below estimates of $51.9 million, but the AI hosting deal is projected to generate $3 billion in contracted revenue over the initial term, with an estimated 80%-85% net operating income (NOI) margin.

Industry observers highlight the broader implications for crypto miners transitioning to AI infrastructure. With energy-efficient facilities and existing power infrastructure, companies like Hive Digital and CleanSpark are also repurposing assets for AI workloads. Cipher’s $9–$11 million per megawatt construction costs and projected $1.08 billion net proceeds from the offering position it to capitalize on surging demand for AI compute capacity.

The AI server market, valued at $128 billion in 2024, is forecast to grow at 28.2% CAGR through 2034, driven by edge computing and cloud expansion. Cipher’s pivot aligns with this trajectory, leveraging Google’s financial backing to scale operations while retaining full ownership of the Barber Lake project. As the company targets $7 billion in potential revenue, its success will hinge on execution risks, including execution of renewal options and market volatility.
