SpaceX purchased roughly 1,279 Cybertrucks in Q4 2025, accounting for about 18% of Tesla's quarterly Cybertruck sales. This matters because it raises questions about whether Tesla's sales figures reflect genuine consumer demand or are artificially inflated by inter-company purchases—a material issue for Tesla shareholders evaluating the Cybertruck's actual market viability. The arrangement represented over $100 million in sales volume that was effectively internal to Elon Musk's corporate empire. The story also highlights a governance gap: Tesla's board and shareholders learned about this bulk purchase through external reporting rather than company disclosure.
