Cipher Digital Inc. details a major shift from pure-play bitcoin mining to developing and operating industrial-scale data centers for high-performance computing, especially AI workloads. The company now controls about 4.2 GW of capacity across 10 sites, including 600 MW of HPC facilities under development for hyperscaler tenants.
Cipher has long-term leases with Fluidstack (backstopped by Google) for a 300 MW Barber Lake site and with Amazon Web Services for a 300 MW Black Pearl site, both in Texas. It continues to run a 207 MW bitcoin mining facility in Odessa with low-cost power, while building a 3.4 GW pipeline of future sites in Texas and Ohio. The company also raised $3.2 billion of debt in 2025 and emphasizes project-level, often non-recourse, financing and long-term leases to support growth while managing risk.
Cipher Digital Inc. filed an 8-K reporting a strategic pivot from bitcoin mining to developing high-performance computing (HPC) data centers, alongside fourth-quarter and full-year 2025 results. Bitcoin mining revenue for 2025 was $223.9 million, but the company posted a GAAP net loss of $822.2 million, or $2.15 per share.
After excluding major non-cash and nonrecurring items, Adjusted earnings were $22.2 million, or $0.06 per diluted share. Cipher rebranded from Cipher Mining to Cipher Digital, secured 600 MW of contracted HPC capacity under long-term leases with AWS, Fluidstack and Google, and expects about $9.3 billion of contracted revenue and roughly $669 million of average annual NOI over the base lease terms.
The company completed three high-yield bond offerings totaling $3.73 billion to fully fund its Barber Lake and Black Pearl data centers, lifting total assets to $4.29 billion and long-term borrowings to $2.71 billion as of December 31, 2025, with cash and cash equivalents of $628 million and additional restricted cash of $2.04 billion.
