Google Council Bluffs East TPU Campus
Deep dive: Anthropic and Google TPUs: stated vs modelled
Also known as Google Council Bluffs (East)
Operated by Alphabet at Google Council Bluffs East Data Center .
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.

Figures are as last publicly reported for the configuration described below, not a live measurement. Where a system was upgraded in place, the post-upgrade configuration is shown and the earlier one appears in the timeline.
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 | 305,600 accelerators | 2026-10-02 | Third-party estimate | About 84,200 TPU v5e, 125,200 v6e, 54,300 v5p and 41,900 v7 (sum is ours). Epoch AI chip estimate (modelled from satellite imagery, cooling equipment and chip availability); not an operator disclosure. | epoch.ai |
| Stated investment | 9 USD bn | 2026-10-02 | Third-party estimate | Epoch AI modelled build cost, compute plus construction, 2025 USD, scaled from IT power; not a disclosed spend. | epoch.ai |
| IT power | 237 MW | 2026-10-02 | Third-party estimate | Epoch AI modelled IT power from satellite imagery and permits; not operator-stated. | epoch.ai |
The read
The newer eastern Google campus in Council Bluffs, Iowa that Epoch AI tracks as an AI-compute site. Google's Iowa page records the original 600 million dollar Council Bluffs facility from 2007, more than 20 billion dollars invested in Iowa and a 7 billion dollar 2025 expansion covering Council Bluffs and Cedar Rapids; it gives no TPU count or power. Epoch AI's AI data centers dataset (CC BY 4.0) estimates about 84,200 TPU v5e, 125,200 TPU v6e, 54,300 TPU v5p and 41,900 TPU v7 chips and 237 MW of IT power as of 2 October 2026, based on Iowa DNR construction permits and satellite imagery, with the first building operational in November 2024. Those are modelled estimates in the metrics table only. Google's published PUE table lists two Council Bluffs campuses and the page does not say which is this one, so no PUE is recorded. Hardware rests on Epoch alone, so the tier is reported.

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.
| Cited source | Result | Found on the page |
|---|---|---|
| datacenters.google | names system and part | Google TPU v6e (Trillium), Google TPU v5p, Google TPU7x (Ironwood) |
| epoch.ai | names system and part | Google TPU v6e (Trillium), Google TPU v5p, Google TPU7x (Ironwood) |
