Cipher Mining Inc. has priced $1.4 billion in 7.125% senior secured notes due 2030 through its subsidiary, Cipher Compute LLC. 

The company said the proceeds will fund the construction of the Barber Lake Facility, a large-scale data center in Colorado City, Texas. 

Moreover, the offering will close on November 13, pending market conditions and final clearances. The notes will be sold privately to qualified institutional buyers under Rule 144A of the Securities Act. 

Cipher will provide a completion guarantee to ensure the project’s timely delivery.

The new financing marks a major step in Cipher’s expansion plans as demand grows for industrial-scale mining and high-performance computing infrastructure. According to the company, the notes will be fully guaranteed by Cipher Barber Lake LLC and backed by first-priority liens on core assets tied to the project.

Funding to Support Barber Lake Facility Completion

Cipher’s $1.4 billion issuance aims to secure capital for one of its most ambitious projects to date. The Barber Lake data center, located near Colorado City, is designed to house high-performance computing systems supporting mining and AI workloads. The company noted that the proceeds will cover construction costs and related expenditures.

Collateral for the offering includes assets from the issuing and guarantor entities, as well as pledged equity interests and accounts related to the buildout. Google LLC has also pledged certain warrants tied to Cipher’s common stock before the project’s completion. These structures are intended to safeguard noteholders while maintaining operational flexibility for Cipher’s expansion strategy.

Cipher Compute’s note offering follows a year of heightened funding activity in the mining sector, as companies seek to expand data center capacity ahead of potential demand surges from AI and Bitcoin mining. 

The company emphasized that this issuance does not represent a public offering and is limited to institutional buyers under regulatory exemptions.

Completion of the Barber Lake Facility remains a central priority for Cipher’s growth roadmap. The project is expected to enhance the company’s operational footprint across Texas, one of the most competitive regions for crypto mining due to its energy infrastructure and favorable policies. 

Cipher’s financing move reflects the industry’s broader push to secure long-term funding ahead of next year’s anticipated mining adjustments.
