SpaceX has significantly expanded its investment in Tesla Megapack systems, spending $295 million in the second quarter and reaching $329 million in total purchases so far this year, according to its latest earnings report.
The figures highlight the close operational ties within Elon Musk's business network. SpaceX, led by Musk, has increasingly aligned its infrastructure with energy storage solutions that can support large-scale digital operations.
Industry observers suggest the batteries may be supporting xAI data centers, where power demand can shift quickly depending on model training and inference workloads. In that environment, Megapacks can deliver rapid backup power and help stabilize energy use during sudden spikes.
For AI facilities, this kind of storage is more than a backup layer. It can smooth consumption peaks, reduce pressure on generators, and improve overall efficiency when computing loads rise and fall throughout the day.
SpaceX also reported holding $131 million worth of Tesla Cybertrucks as of December 2025, reflecting the broader overlap between Musk's companies across mobility, energy, and computing. As AI infrastructure grows, battery storage is likely to remain a key part of building faster, more resilient digital systems. The trend points toward a future where energy flexibility becomes as important as computing power itself.
