What happened
In 2026, SpaceX has spent $329 million on Tesla Megapacks, with $295 million allocated in the second quarter alone. These batteries are likely intended for use at xAI data centers, which require stable power for AI operations.
Key evidence
- SpaceX's total expenditure on Tesla Megapacks reached $329 million in 2026, as reported in their earnings report.
- In Q2 2026, SpaceX spent $295 million on these battery storage devices, indicating a significant investment in energy solutions.
- Prior to merging with SpaceX, xAI had purchased $430 million worth of Megapacks for its data centers, highlighting the ongoing demand for large-scale battery solutions.
Why it matters
The substantial investment in Tesla Megapacks by SpaceX reflects a strategic move to enhance power reliability for AI workloads at xAI data centers. As AI operations can have fluctuating power demands, integrating large-scale batteries can help mitigate costs and ensure consistent performance, which is critical for the efficiency of AI model training and inference.

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’s earnings report released 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 xAI acquired his social media platform, X, in 2025. Earlier this year, SpaceX gobbled up xAI.
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 — including dozens of unpermitted turbines at 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.
