- Construction: Galaxy Helios is a multi-phase conversion and expansion of Argo Blockchain’s former Bitcoin-mining facility into an AI/HPC data-center campus. The original facility began construction in July 2021, energized Phase 1 and commenced mining operations on May 5, 2022. Galaxy acquired the facility in December 2022. Galaxy’s AI retrofit delivered approximately 200 MW of gross power, including 133 MW of critical IT load, in 2026; Phase II greenfield construction is underway, with data-hall deliveries expected in the first half of 2027. Three additional Phase II buildings—Helios 2, 3, and 4—were reported as permitted in March 2026.

## Compute and operations

- Facility classes: hyperscale, ai_hpc, crypto_mining
- Workloads: AI training, AI inference, high-performance computing

## Data quality

- The exact site is supported by the Helios name, Dickens County location, and reporting that places later phases near the initial facility off County Road 112.
- Galaxy’s statements about jobs, community commitments, and quality-of-life benefits are operator or county-official claims rather than independently audited outcomes.
- The Texas Spur tax-abatement article has inconsistent date metadata concerning the July 28 commissioners session.
- The May 2026 tax-abatement article is paywalled in the retrieved copy, although its visible headline identifies Galaxy Helios II and Galaxy Helios III.
- No unsupported water-use, cooling, PUE, WUE, building-count, or equipment claims are included.
- Power values retain their reported, requested, contracted, energized, gross-campus, or critical-IT basis.
