SpaceX has bought $329M in Tesla Megapacks this year for xAI data centers

SpaceX spent $329 million on Tesla Megapack battery storage devices so far this year, according to the company's earnings report released on Tuesday. The company spent $295 million on the devices in the second quarter alone. The purchases illustrate the interconnected nature of Elon Musk's companies. Musk is the CEO and largest shareholder of SpaceX and also runs Tesla. Musk's artificial intelligence business xAI acquired his social media platform X in 2025, and SpaceX acquired xAI earlier this year. 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.
