SpaceX was the biggest buyer of Tesla Cybertruck pickups in the United States in the fourth quarter of 2025, buying nearly one in five of the electric trucks sold, according to registration figures. The purchases helped lift Cybertruck registrations even as overall demand for the vehicle kept sliding.
Registration data from S&P Global Mobility, first reported by News, suggests SpaceX spent more than $100 million on the trucks. Without that buying spree, Cybertruck registrations would have fallen by 51 per cent in the fourth quarter, a sign of how heavily Tesla's newest pickup leaned on Elon Musk's own business to keep sales moving.
The numbers land against a backdrop that has been hard for Tesla to spin as anything but a miss. Musk predicted in 2023, ahead of the Cybertruck launch, that Tesla would be selling 250,000 Cybertrucks a year by 2025. Instead, actual sales last year were just over 20,000 units, after Tesla sold 38,965 Cybertrucks in 2024. The gap between the promise and the result has only widened as the truck has reached the market.
The tension is in the customer list itself. SpaceX is not a random fleet buyer helping an unrelated product line; it is Musk's rocket company, stepping in as the largest purchaser of a vehicle made by his carmaker. That helped Tesla's numbers in the quarter, but it also underlines how much the Cybertruck has struggled to build demand outside Musk's own corporate orbit.
For Tesla, the latest figures are less a sign of momentum than a reminder of what the Cybertruck needs next: buyers who are not already inside Musk's empire.
