Google TPU (Ironwood) capacity for Anthropic
Deep dive: Anthropic and Google TPUs: stated vs modelled
Operated by Alphabet at Google Cloud (undisclosed location) .
Phase 1 seed dataset, compiled by hand. These rows were built from public operator, laboratory and vendor sources. A mechanical second-reader pass has since fetched every cited source: 1092 of 1153 systems have a readable citation that names them, and 40 are genuinely weakly sourced. Every claim carries its source and a confidence tier. Treat anything below verified as a lead, not a citation.

What this machine is made of
One row per supplier relationship. “Supplier at build” is the company that shipped the part at the time; where that company has since been acquired, the parent it rolls up to today is shown beside it. That distinction is what makes ticker-level aggregation possible across a thirty-year dataset.
| Role | Part | Supplier at build | Quantity | Confidence | Source |

| Metric | Value | As of | Basis | Note | Source |
|---|---|---|---|---|---|
| Accelerators | 1,000,000 accelerators | 2025-10 | Design target | Anthropic and Google Cloud both state up to one million TPUs; a ceiling in a commitment, no sites named | anthropic.comgooglecloudpresscorner.com |
| Facility power | 1,000 MW | 2026-12 | Design target | Both parties: well over a gigawatt of capacity coming online in 2026; 1,000 MW is the floor, scope (IT or facility) not stated | anthropic.comgooglecloudpresscorner.com |

The read
Google Cloud's October 2025 commitment to give Anthropic access to up to one million seventh-generation (Ironwood/TPU7x) TPU chips, worth tens of billions of dollars and expected to bring well over a gigawatt of capacity online in 2026. Google's own press corner and Anthropic's own newsroom independently state the same chip count, generation name and capacity figure, so the tier is verified. The one million figure is a ceiling on the commitment, not a confirmed installed count, so no quantity is recorded on the accelerator edge; as with Meta's RSC phase-two target, a stated plan is not the same fact as a deployed count. Neither source names a location beyond 'the majority... in the United States', so the row sits at Google's existing undisclosed-site entry. No FLOPS figure is published for this specific commitment.

Source check
We fetched this system's own citations and recorded whether each page actually mentions it. This is a corroboration signal, not a fact check, and it is published so you can see how well the sourcing holds up rather than take it on trust.
