What changes the reading
- Galaxy reports the first Helios phase as delivered under a different owner entity. That operating capacity is not counted as part of this second phase profile.[1][3]
- The financing filing describes two buildings. Three accessibility records use the same second phase owner for separately named buildings. The public records do not show how those scopes map to each other, so their areas and costs are left separate.[2][4][5][6]
- The company says foundation work is underway. The future delivery date remains a schedule and is not treated as delivered customer capacity.[3]
- CoreWeave is both occupant and one of the operators in the certification. Public filings do not name the eventual user of the computing rented from CoreWeave.[1][2][3]
Still not public
- The mapping between the financed buildings and the accessibility filings is not public.
- No second phase capacity has been reported as delivered.
- The eventual computing user behind CoreWeave has not been named.
- Current measured electrical demand is not public.
- Cooling design and measured water use are not public.

What was filed to build it
Texas registers every large construction project with a second agency. These filings were made by a company this record already names.
$3.50 billion across 3 filings, 898,312 sq ft.
An estimated cost at filing is not a final cost, and a filing is not proof a building went up. How this register works.
The registry entry for this facility comes from the Texas Comptroller's certified list of data centers holding a sales tax exemption. Owner, occupant and operator are roles in that filing rather than descriptions of who runs the building.
