Current status

Operating at 300+ MW with 220,000+ NVIDIA GPUs. Fully leased to Anthropic ($1.25B/month through May 2029) with additional capacity ramping for Google ($920M/month, ~110,000 GPUs, October 2026 through June 2029). Colossus 2, the separate Blackwell/Blackwell-Ultra-generation follow-on system nearby in Memphis, moved from under-construction to operational on September 3, 2026 and was reported as the world's largest AI data center by IT power capacity (roughly 946 MW, with Epoch AI estimating around 1.1 million H100-equivalent compute units, en route to a reported ~1,531 MW in early 2027); it hosts the separate Reflection AI compute deal disclosed in June 2026. Reverified in early September 2026: Colossus 1's own capacity and its Anthropic/Google contract terms are unchanged.

  1. SpaceX inks $30B Google AI compute deal ahead of IPO

    SpaceX disclosed in an amended S-1 on June 5 that Alphabet's Google will pay it $920 million per month from October 2026 through June 2029 - about $30 billion - for roughly 110,000 NVIDIA GPUs, CPUs, memory, and related infrastructure routed through its Memphis Colossus 1 data center. Coming on top of a separate $1.25B/month Anthropic pact unveiled May 6 for the full ~220,000-GPU, 300 MW Colossus 1 capacity, the deal lifts SpaceX's disclosed AI-compute backlog to more than $70 billion and reframes the post-xAI-merger company as a major AI hyperscaler days before its planned June 12 Nasdaq debut under ticker SPCX.
