SpaceX has ramped up purchases of Tesla Megapack, spending $295 million on the battery storage devices in the second quarter and $329 million so far this year, according to the company’searnings reportreleased on Tuesday. The purchase illustrates just how interconnected Elon Musk’s universe of companies are. Musk, who is the CEO and largest shareholder of SpaceX, also runs Tesla. Musk’s artificial intelligence business xAIacquiredhis social media platform, X, in 2025. Earlier this year, SpaceXgobbled upxAI. The industrial-scale batteries are likely being deployed at the company’s xAI data centers. Before xAI merged with SpaceX, the AI company bought $430 million worth of Megapacks for its data centers. In the first quarter of this year, xAI had purchased only $34 million worth of the equipment. SpaceX also reported that as of December 2025, it had acquired $131 million worth of Tesla Cybertrucks at manufacturer’s suggested retail price, according to its regulatory filing. Though xAI has leaned heavily on natural gas to power its data centers — includingdozens of unpermitted turbinesat a site in Mississippi not far from the Colossus data center project — large batteries like the Megapack are still a critical part of data centers. In addition to providing substantial backup power that can be tapped in a second or less, batteries can provide extra power to GPUs when they demand it. AI data centers don’t draw power consistently. Rather, their power demand ramps up and down depending on the demands of training AI models and running inference. Such peaks can incur significant charges from a local utility or overwhelm on-site generators. Batteries help smooth out those peaks, lowering costs while ensuring that the data center can operate consistently.
