HAWTHORNE, Calif. — Tucked inside SpaceX's debut earnings report was a detail that neatly captured how tightly Elon Musk's companies are intertwined: the rocket maker has bought roughly $329 million worth of Tesla Megapacks so far in 2026, including about $295 million in the second quarter alone.
Powering The Launch Business With Tesla Batteries
The disclosure, first flagged by TechCrunch from SpaceX's filing, shows the launch giant leaning heavily on Tesla's grid-scale battery to power its sprawling ground operations. Megapacks provide backup and load-smoothing muscle for energy-hungry sites — from the Starbase production and launch complex in Texas to the network of ground stations that keep Starlink humming. As SpaceX scales launch cadence and satellite deployment, its appetite for reliable on-site energy storage has grown right alongside it. That expansion is the same momentum we described in our coverage of SpaceX's record $7.8 billion quarter.
A Win For Tesla Energy
For Tesla, the purchases are a tidy endorsement of its fastest-growing division. Tesla Energy has been setting deployment records, and a marquee customer like SpaceX buying hundreds of millions of dollars of hardware underscores the product's appeal beyond utilities and data centers. The arrangement also highlights the practical side of the so-called Muskonomy: Tesla builds the storage, SpaceX buys it, and both companies benefit from the vertical relationship. It is a real-world complement to the compute and connectivity tie-ups behind our report on Starlink topping 10,800 satellites.
