Short Code: McLennan Campus
Site planned for 2028 and has expansions through 2030
Lot Size: 300 acres

Cipher Digital’s proposed campus, code-named "McLennan," marks a strategic pivot for the developer from cryptocurrency mining to high-performance computing (HPC) and AI infrastructure.

Strategically situated on a 300-acre site just north of downtown Riesel and directly adjacent to the Sandy Creek Generating Station, the hyperscale-ready development aims to leverage direct proximity to major high-voltage transmission lines for an anticipated 2028 energization. To mitigate local environmental and community impact concerns regarding resources, the project intends to bypass the municipal water supply entirely, opting instead to utilize recycled and treated wastewater infrastructure already serving the neighboring power plant.

Overview

Cipher Digital (NASDAQ: CIFR), formerly Cipher Mining, is a New York-based developer and operator of large-scale data center campuses in Texas. CEO Tyler Page leads the company. Cipher's footprint spans operational mining facilities (Odessa, Alborz, Bear, Chief) and a deep pipeline of HPC/AI campuses in West Texas including Black Pearl, Barber Lake, Stingray, Reveille, Mikeska, McLennan, Milsing, Ulysses, and the Colchis development.

Strategic pivot to HPC/AI (2026)

On the Q1 2026 earnings call (May 5, 2026), Cipher formally rebranded from Cipher Mining to Cipher Digital, reflecting a strategic shift to hyperscale HPC/AI hosting as the company's forward business. Bitcoin mining at Black Pearl is being wound down to redirect power and land to AI tenants.

Contracted backlog now totals approximately $9.3 billion, anchored by three hyperscale leases:

  • AWS. 15-year lease for 300 MW of HPC capacity.
  • Fluidstack / Google-backed. 10-year lease for 300 MW, with the Barber Lake facility expected to commence operations in September 2026.
  • Third hyperscaler. An additional hyperscale campus lease signed during Q1 2026.

Q1 2026 financials

  • Bitcoin mining revenue: $34.8 million (down from approximately $60 million in Q4 2025) as mining at Black Pearl is wound down.
  • Net loss: $114 million.
  • Funding: Closed a $2 billion high-yield bond for the Black Pearl HPC buildout and a $200 million revolving credit facility.

Capex direction

New capital is flowing fully to HPC/AI buildout. Existing mining capacity is treated as legacy that gets converted to hyperscale colocation as power and infrastructure are redirected to AWS, Fluidstack, and the third hyperscale tenant.
