Vertiv Holdings Co. (NYSE:VRT) shares closed higher on Tuesday after the company unveiled a major AI infrastructure initiative, teaming up with NVIDIA Corp. (NASDAQ:NVDA) and artificial intelligence firm iGenius to deploy one of the world's most powerful AI supercomputers.

The project, dubbed "Colosseum," is set to launch in Italy later in 2025 and aims to support mission-critical, sovereign AI workloads across highly regulated sectors.

Colosseum leverages the NVIDIA DGX SuperPOD framework and will run on NVIDIA's advanced Grace Blackwell Superchips.

"The unit of compute is no longer the chip — it's the system, the AI Factory," said the president of Vertiv, EMEA, Karsten Winther.

"Through our collaboration with NVIDIA and visionary AI player iGenius, we are proving the efficiency and system-level maturity of delivering the data center as a unit of compute, unlocking rapid adoption of AI-native power and cooling infrastructure as a catalyst for AI at scale."

Positioned in southern Italy, the facility is designed to meet local sovereignty requirements and adhere to rigorous regulatory standards in industries such as healthcare, finance, and public administration.

Colosseum integrates Vertiv's data center solutions with NVIDIA's AI technologies to enable real-time simulations and faster deployment.

Built on Vertiv's 360AI architecture and tailored for NVIDIA's GB200 NVL72, it offers a scalable, efficient platform for next-generation AI systems.

Vertiv's turnkey AI data center package encompasses power, cooling, monitoring, and maintenance, with initial support for up to 132kW per rack.

Its hybrid design blends modular exterior systems with adaptable interior compute spaces, cutting build times by as much as half when compared to conventional data centers.

The software will be central to Colosseum's functionality, with NVIDIA Mission Control and Vertiv Unify managing real-time coordination of computing, power, and cooling.

This integration links digital twins with physical systems, enabling predictive maintenance, automation, and risk reduction through advanced simulations.

The Colosseum serves as a prototype for scalable sovereign AI data centers worldwide, blending high-density computing with localized control. Vertiv and NVIDIA plan to expand this model with future platforms like the DGX GB300.

Price Action: VRT shares closed higher by 6.29% to $71.82 on Tuesday.
