According to the latest data, Elon Musk’s company SpaceX has emerged as the largest buyer of Elon Musk’s own company, Tesla’s Cybertruck.

SpaceX bought nearly one in five Cybertrucks sold in the U.S. in the fourth quarter of 2025.

SpaceX spent more than $100 million on these electric trucks, according to registration data from S&P Global Mobility (first reported by Bloomberg News).

Although SpaceX supported Tesla sales, overall Cybertruck sales still fell in the fourth quarter.

If the SpaceX purchase were not included, Cybertruck registrations would have fallen by 51% in the fourth quarter.
