Jane Street, one of the most powerful quantitative trading firms on the planet, is building its own data center. The firm will finance the project independently, a move that signals just how desperate the race for compute power has become, even among companies that already operate serious GPU clusters.

This isn’t a company dabbling in infrastructure for fun. Jane Street already runs a facility in Texas housing 4,032 liquid-cooled GPUs spread across 56 racks, consuming under 10 MW of power. Building a new, purpose-built data center suggests that existing capacity simply isn’t cutting it anymore.

From cloud customer to infrastructure owner

Back in April 2026, the firm committed $6 billion to CoreWeave’s AI cloud platform, including a $1 billion equity stake. That deal gave Jane Street access to cutting-edge NVIDIA hardware through CoreWeave’s infrastructure.

The proposed facility’s capacity hasn’t been finalized, though one report suggests targets in the range of 100-200 MW. For context, the existing Texas facility operates under 10 MW. If the upper end of that range materializes, the new data center could represent a roughly twentyfold increase in power capacity.

Jane Street is also actively hiring data center engineers globally. The firm is in early discussions with companies across technology, cryptocurrency, and finance for potential collaboration on the project, though nothing concrete has emerged from those conversations yet.

Why a trading firm needs this much compute

The firm operates a dedicated machine learning team focused on scaling model training and deployment. Training large models on financial data requires the kind of sustained GPU access that cloud providers can’t always guarantee, especially during periods of peak demand.

Internally, Jane Street has even developed a system called “hive bucks” to manage competitive allocation of compute resources among its teams.

What this means for crypto and financial markets

Jane Street is already one of the largest market makers in cryptocurrency trading. The firm has been a significant liquidity provider across multiple crypto exchanges and played a notable role in facilitating trading around spot Bitcoin ETF launches.

The $6 billion CoreWeave commitment plus a proprietary data center build puts Jane Street’s total AI infrastructure investment well into the billions.
