SpaceX bought $295M of Tesla Megapacks in Q2 for AI data centers
SpaceX purchased $295 million worth of Tesla Megapacks in Q2 2026 alone, bringing its first-half total to $329 million — batteries powering xAI's Colossus AI data center near Memphis, Tennessee, adding to the $430 million xAI spent on its own before merging with SpaceX, as related-party dealing among Musk's companies keeps growing.
Tesla, SpaceX, and xAI — all led by Elon Musk — have a history of sharing resources and personnel across the companies, and the latest disclosed figures show that internal dealing keeps expanding.
SpaceX spent $295 million on Tesla Megapacks in the second quarter of 2026 alone, bringing its cumulative spending for the first half of the year to $329 million.
The batteries are being installed to help power xAI's Colossus AI data center near Memphis, Tennessee. Large battery storage systems like these discharge power stored from a mix of sources — fossil fuels, solar, and wind — to data centers and the grid, helping prevent blackouts and keep supply stable.
xAI had already spent $430 million of its own on Tesla Megapacks before merging with SpaceX, so this quarter's SpaceX purchases add to an already sizable pile of related-party spending among Musk's companies.
For Tesla, expanding Megapack demand from sister companies like SpaceX and xAI adds to energy-segment revenue, but the growing web of related-party transactions among Musk's various companies is also a governance factor shareholders will want to keep watching.
