SpaceX Fuels AI with Tesla Megapacks
5 Aug
Summary
- SpaceX spent $295 million on Tesla Megapacks in Q2.
- Batteries ensure stable power for AI data centers.
- SpaceX also bought $131 million in Cybertrucks.
SpaceX has made substantial investments in Tesla's Megapack battery storage systems. In the second quarter of 2026, the company allocated $295 million to these purchases, bringing the total year-to-date expenditure to $329 million. This strategic acquisition highlights the deep integration between Elon Musk's various companies.
The industrial-scale batteries are anticipated to be deployed at SpaceX's xAI data centers. Prior to its merger with SpaceX, xAI had already committed $430 million for Megapacks for its data infrastructure. In the first quarter of 2026, xAI’s investment in this equipment was a more modest $34 million.
These large battery systems are vital for AI data centers, providing rapid backup power and smoothing out power demands. AI operations fluctuate significantly, with power needs spiking during model training and inference. Batteries help manage these peaks, reducing utility costs and ensuring consistent operational uptime.
Further demonstrating the interconnectedness of Musk's ventures, SpaceX also reported acquiring $131 million worth of Tesla Cybertrucks at their manufacturer's suggested retail price as of December 2025. While xAI has utilized natural gas for its data centers, batteries like the Megapack are essential for reliable performance.
