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.
