SpaceX has purchased $329 million worth of Tesla Megapacks so far this year, spending $295 million alone in the second quarter. This figure comes from the company’s earnings report released on Tuesday and highlights the deep integration between Elon Musk’s various businesses. The industrial-scale batteries are likely being deployed at the company’s xAI data centers to manage power demands. Before SpaceX acquired xAI earlier this year, the artificial intelligence firm bought $430 million worth of Megapacks for its facilities. In the first quarter of this year, xAI had purchased only $34 million of the equipment, showing a sharp increase in activity.
These batteries are critical for data centres because their power usage does not remain consistent. AI infrastructure ramps up and down depending on the specific requirements of training models or running inference. Such peaks can incur significant charges from a local utility or overwhelm on-site generators. Large batteries help smooth out those fluctuations, lowering costs while ensuring the data centre can operate consistently. They provide substantial backup power that can be tapped in a second or less and offer extra power to GPUs when they demand it.
- SpaceX acquired $131 million worth of Tesla Cybertrucks as of December 2025.
- xAI has relied heavily on natural gas to power its facilities, including dozens of unpermitted turbines.
- The Colossus data centre project is located in Mississippi near other battery installations.
