Cybertrucks: Operational Vehicles for Space and AI Facilities
SpaceX and xAI purchased approximately $131 million worth of Tesla Cybertrucks in 2025, according to the filing. The vehicles are being used across launch facilities, industrial sites, and AI-related operations, expanding the Cybertruck’s role beyond the consumer market into commercial and industrial applications.
Megapacks: Large-Scale Energy Infrastructure Expansion
Tesla’s Megapack energy-storage systems represented the largest share of intercompany sales. According to the prospectus, Megapack revenue from SpaceX and xAI reached approximately $191 million in 2024 and $506 million in 2025. These systems are used to support energy storage and power management for rocket operations, data centers, and other high-energy infrastructure projects.
Strategic Integration Through Shared Infrastructure Projects
The companies are also collaborating on semiconductor manufacturing initiatives, including a project referred to as “Terafab.” According to reports, the initiative is focused on developing custom chips for artificial intelligence systems, vehicles, and aerospace applications. The project reflects broader efforts to align computing, transportation, and infrastructure development across Musk’s business network.
Governance and Leadership Connections
The organizational ties between the companies extend into corporate governance. SpaceX plans to add Tesla director Ira Ehrenpreis to its board alongside investor Randy Glein, who has served as a SpaceX board observer for several years. These overlapping leadership structures support coordination on long-term investments and operational strategy across the companies.
Financial Disclosure and Investor Visibility
The financial relationships became visible through disclosures connected to SpaceX’s IPO preparations, which required detailed reporting of intercompany transactions. The filings provide investors with additional visibility into how products, infrastructure, and capital move across Musk’s companies.
The disclosures also show how Tesla’s vehicle and energy businesses are increasingly connected to demand generated by artificial intelligence infrastructure and space operations. SpaceX’s satellite network and xAI’s computing requirements continue to create additional demand for battery systems, transportation products, and energy-storage technology supplied by Tesla.
