SpaceX’s $329M Tesla Megapack Spend Highlights Musk Company Ties

SpaceX has spent $329 million on Tesla Megapack battery storage devices so far this year, according to TechCrunch, citing the company’s earnings report. The article says $295 million of that total came in the second quarter. The purchase is notable because SpaceX and Tesla are both led by Elon Musk, making the transaction another example of overlap across Musk-linked companies.

TechCrunch reports 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, while first-quarter purchases this year totaled $34 million. For readers tracking AI infrastructure, the takeaway is straightforward: energy storage is becoming a visible part of the data center buildout story.

The article explains that large batteries can provide backup power that can be tapped in a second or less. They can also provide extra power to GPUs when demand spikes during AI model training or inference. Because AI data centers do not draw power consistently, batteries can help smooth peaks that might otherwise raise utility charges or strain on-site generators.

The TechCrunch report frames the purchase as evidence of how interconnected Elon Musk’s companies are. Musk is CEO and largest shareholder of SpaceX and also runs Tesla, while xAI acquired X in 2025 and SpaceX later acquired xAI. 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.
