Colossus 1

Type: Data center facility
Location: Memphis, Tennessee
Owner: SpaceXAI (formerly xAI)
Status: Operational, leased to Anthropic (May 2026)

Overview

Colossus 1 is a large-scale AI training data center built by xAI in Memphis, Tennessee in 2025. The facility set records for GPU cluster deployment speed, going from empty building to 100,000 H100 GPUs in approximately 120 days.

Specifications

  • Power capacity: 300+ megawatts
  • GPU count: 220,000+ Nvidia GPUs (H100, H200, and GB200 accelerators)
  • Deployment timeline: ~120 days from empty building to 100K H100s operational (2025)

Timeline

  • 2025 — Built by xAI in Memphis, TN; set records for GPU cluster deployment speed (100K H100s in ~120 days)
  • 2026-05-06 — xAI migrated training workloads to Colossus 2 (larger next-generation facility); entire Colossus 1 capacity leased to Anthropic

Strategic Context

The Colossus 1 lease to Anthropic (announced May 6, 2026, one month before SpaceXAI's June 2026 IPO roadshow) serves dual purposes: generates revenue from otherwise-idle infrastructure while xAI operates Colossus 2, and demonstrates external customer demand for SpaceXAI's data center infrastructure business ahead of the IPO.

Elon Musk characterized the decision to lease to Anthropic (a competitor) as passing the "evil detector" test — suggesting the deal was evaluated on strategic and financial merits rather than competitive concerns.
