SpaceX purchased 1,279 Cybertrucks in Q4 2025, accounting for 18% of all Tesla Cybertrucks registered in the US that quarter — essentially one in five vehicles sold. This matters because it reveals Cybertruck demand from regular consumers is weaker than headline sales numbers suggest, with Elon Musk's own company propping up the pickup's quarterly volume. Tesla did not disclose SpaceX's bulk buying to shareholders, raising questions about transparency in reporting subsidiary purchases that inflate parent-company sales figures.
