Elon Musk met with SpaceX's Brent at midnight to oversee xAI's new Colossus 2 supercomputer, set to become the world's largest and most powerful data center. The facility is incorporating over $375 million worth of Tesla Megapacks for sustainable energy to support advanced AI workloads.
On December 10, 2025, at midnight, Elon Musk convened with Brent from SpaceX at xAI's newly developed Colossus 2 supercomputer. According to Tesla commentator Sawyer Merritt, this meeting highlighted the project's progress, positioning Colossus 2 as the largest and most powerful data center globally.
The supercomputer is integrating over $375 million in Tesla Megapacks, Tesla's large-scale battery storage systems. These Megapacks are designed to provide sustainable energy solutions, powering the intensive computational demands of advanced AI workloads. This integration underscores a strategic collaboration between xAI and Tesla, emphasizing energy efficiency in high-performance computing.
Colossus 2 combines scalable compute resources with leading-edge hardware, aiming to enhance operations in data centers. The project is expected to accelerate AI model training capabilities, enabling faster innovation in enterprise and research applications. As Sawyer Merritt noted in his post: "Elon meeting with @BrentM_SpaceX at midnight at xAI’s new Colossus 2 supercomputer, which will be the largest and most powerful data center in the world. Over $375 million worth of Tesla Megapacks are being installed there."
This development signals broader opportunities in AI infrastructure, where sustainable energy plays a key role in supporting scalable and efficient systems. No specific location details for the facility were provided in the sources.
