Jane Street Texas GPU Cluster

Name: Jane Street (Texas)
Address: USA

Operated by Jane Street at Jane Street (Texas) .

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
Integrator	- 4,032 GPUs across 56 racks, retrofitted for liquid cooling and tied together by roughly 8,000 km of fiber; built and operated in-house by Jane Street's own physical engineering team rather than a third-party integrator.	Jane Street	-	Reported	janestreet.com cryptobriefing.com

The read

Jane Street, a quantitative trading firm and major options/ETF liquidity provider, disclosed this cluster in a May 2026 company blog post accompanying a video tour led by podcaster Dwarkesh Patel: 4,032 GPUs across 56 racks, retrofitted for liquid cooling, tied together by roughly 8,000 km of fiber, in one of the firm's Texas data centers. Independent tech-press coverage of the same tour (cryptobriefing.com) corroborates the GPU and rack counts. GPU vendor/model is not stated by Jane Street itself; contemporaneous reporting ties an NVIDIA Vera Rubin platform to a separate roughly $6 billion CoreWeave cloud agreement Jane Street signed around the same time, which is a distinct rented-capacity relationship and is not conflated with this owned, on-premise cluster, so no accelerator vendor/model is recorded here. Jane Street has also disclosed early-stage discussions toward a much larger, 100-200 MW data center; that project is unbuilt and not recorded as a separate row. No TOP500/HPL submission exists for this cluster.
