Timeline
The former [crypto mining](https://web.archive.org/web/20250423225644/https://investor.galaxy.com/news/news-details/2025/Galaxy-Announces-Commitment-with-CoreWeave-to-Host-Additional-Artificial-Intelligence-and-High-Performance-Computing-Infrastructure-at-Helios-Data-Center-Campus/default.aspx) Helios site begins converting the first building and expanding, with land cleared for additional buildings.
Backup generator pads and steel framing for chillers are visible, similar to the [3D renderings](https://www.galaxy.com/data-centers).
Building 1 appears substantially complete. The main white-roofed data hall is visible with exterior mechanical/electrical equipment rows installed on both sides, and adjacent generator/equipment pads plus laydown yards are active. A large graded pad north of Building 1 suggests preparation for the next phase/building. No clear satellite evidence that the AI/HPC facility is operational yet.
Building 1 appears externally complete and likely Ready for Service, with all cooling/roofing/generators in place, but we're not labeling it operational yet due to visible surrounding yard/construction work. CoreWeave likely still needs time to install chips and use all their designated chip capacity. The pad to the northeast has foundations being laid out for Building 2.
Building 1 operational at full capacity. This is based on "Phase I", which is [expected](https://investor.galaxy.com/news/news-details/2025/Galaxy-Announces-Third-Quarter-2025-Financial-Results/default.aspx) to be operational by the end of the first half of 2026. We added two months of overhead to account for remaining construction and/or installation of CoreWeave's chips, since the June 17 image still showed active minor construction around the building.
200 MWBuilding 2 and 3 are operational at full capacity. This corresponds to "Phase II", which is [expected](https://investor.galaxy.com/news/news-details/2025/Galaxy-Announces-Third-Quarter-2025-Financial-Results/default.aspx) to be delivered "throughout 2027". We assume it takes until the end of 2027 to reach full capacity.
600 MWBuilding 4 operational at full capacity. This corresponds to "Phase III", which is [expected](https://investor.galaxy.com/news/news-details/2025/Galaxy-Announces-Third-Quarter-2025-Financial-Results/default.aspx) to be delivered "starting in 2028". We assume it takes until the end of 2028 to reach full capacity.
