Nvidia and AI Data Center Suppliers See Stock Surges on Partnership

Fluence Energy FLNC shares soared roughly 39% after the company unveiled a three-way collaboration with Siemens and NVDA to design power-dense AI data centers. The reference design pairs Nvidia's Vera Rubin NVL72 rack-scale systems with a 136 MW data-center blueprint that uses Fluence battery storage as the sole energy-storage partner.

The architecture calls for batteries sized to hold two to three hours of power rather than the usual one, expanding the hardware Fluence can sell per project and reinforcing a record order backlog reported at about $10.1 billion. The deal frames energy storage as a core enabler of AI compute, where power availability has become a binding constraint.

Separately, Cadence Design Systems rose about 9% after launching a Level-5 AI chip verification tool at Computex, underscoring how the AI buildout is lifting suppliers across the design and power stack. Investors will watch whether reference-design wins convert into firm orders across NVDA's data-center ecosystem.
