Coreweave Helios
Running (some may still be expanding)
Coreweave Helios is an AI data center in Afton, Texas, developed or operated by CoreWeave for OpenAI. Satellite imagery shows its computers drawing about 132 MW today, against 528 MW planned.
U.S. average: 18.2¢ (+3.4%).

Satellite figures are Epoch AI estimates from imagery of buildings, cooling and power equipment; about 80% fall within a factor of 1.4 of the true value.

Building 4 operational at full capacity. This corresponds to "Phase III", which is expected to be delivered "starting in 2028". We assume it takes until the end of 2028 to reach full capacity.
- Jan 1, 2028ScheduledSatellite analysis by Epoch AI · 396 MW planned
Building 2 and 3 are operational at full capacity. This corresponds to "Phase II", which is expected to be delivered "throughout 2027". We assume it takes until the end of 2027 to reach full capacity.

Building 1 operational at full capacity. This is based on "Phase I", which is expected 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.

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.
- Apr 4, 2026Satellite analysis by Epoch AI · 0 MW in use
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.

Backup generator pads and steel framing for chillers are visible, similar to the 3D renderings.

Land clearing: The former crypto mining Helios site begins converting the first building and expanding, with land cleared for additional buildings.
No hearings, court cases, approvals or disputes are on record for this project yet.
