What changes the reading

  • A later agreement that autumn took Fluidstack to the entire capacity of the site. Cipher Mining rebranded to Cipher Digital the following spring as its business moved from mining to hosting.[3][4]November 7th, 2025
  • Google received warrants alongside the backstop, so its exposure here is both as guarantor and as a shareholder in the landlord.[2]

Still not public

  • Building square footage is not public.
  • Cooling design is not public.
  • Substation and interconnection detail is not public.
