Torus raises $500M Series C led by Magnetar for modular AI power pods

Its pitch: skip years of new power-plant construction by tapping stranded capacity already sitting idle at substations.

• Torus launched Foundry, a prefabricated system packaging power, storage, cooling, networking and compute, and simultaneously announced $500 million in growth funding led by Magnetar.
• Torus is a Salt Lake City energy-storage maker that built its business on modular battery systems for factories and commercial sites before pivoting that expertise toward AI compute.
• Each Foundry site adds 1-20 megawatts of inference capacity and can go from signed contract to running AI workloads in 12-16 weeks by using spare capacity at existing grid transformers.
• A single Foundry container packs 576 Nvidia HGX B300 GPUs into about 577 square feet, paired with Torus Reserve battery and flywheel storage to manage demand spikes.
• Torus cites McKinsey projections that data-center demand for AI inference will grow 35% annually through 2030, versus 22% for training, as the driver behind Foundry's design.
• Magnetar first backed Torus with a $200 million commitment in September 2025 before leading this far larger round to fund AI infrastructure manufacturing.
• By reusing existing grid interconnections instead of waiting on new power plants or transmission lines, Foundry targets the single biggest bottleneck slowing AI data center buildout today.
