Anthropic locks ~10GW across Amazon, Google/Broadcom and SpaceX
Up to $25bn with Amazon, a multi-gigawatt Google-TPU/Broadcom deal, and a monthly lease of xAI's Colossus 1 output
Summary
Alongside its $65bn Series H, Anthropic disclosed compute deals totalling roughly 10 gigawatts of reserved training power. Amazon expanded its commitment to as much as $25bn for up to 5GW of dedicated capacity, ~1GW online by end-2026. Google and Broadcom locked a further 5GW of next-generation TPU capacity beginning 2027, reported as a ~$200bn-over-five-years commitment. Separately, Anthropic agreed to rent the entire output of Spacex/xAI's Colossus 1 data centre at ~$1.25bn/month through May 2029, 220,000 H100-class GPUs and 300MW immediately. The pledges underwrite the near-$1tn valuation and rival Openai's Nvidia-anchored build-out.
By the numbers
- ~10GW, total reserved training power.
- up to $25bn, Amazon commitment, up to 5GW.
- 5GW, Google/Broadcom TPU capacity from 2027.
- ~$1.25bn/month, SpaceX Colossus 1 lease through May 2029.
- 220,000, H100-class GPUs in the Colossus 1 deal.
Why it matters
Compute reservation has become the real moat: Anthropic's valuation rests as much on locked gigawatts as on revenue. The Google/Broadcom TPU tilt diversifies away from Nvidia and gives Google a strategic supply hook into a rival; renting xAI's Colossus output ties two competitors together through SpaceX.
What to watch
- Whether the 2027 TPU capacity arrives on schedule.
- Power and grid constraints on the Amazon 5GW build.
- Whether Nvidia's share of frontier-lab compute keeps eroding to custom silicon.
