Elon Musk’s SpaceX is the largest buyer of Cybertrucks from his other company, Tesla, according to the latest registration figures.
Nearly one in five Tesla Cybertrucks sold in the US in the fourth quarter of 2025 were purchased by his private space company.
Registration data from S&P Global Mobility, first reported by Bloomberg News, suggests that SpaceX spent more than $100 million (£74m) on the electric trucks.
Despite SpaceX propping up Tesla’s sales, the number of Cybertrucks continued to fall in Q4.
Without SpaceX, Cybertruck registrations would have fallen by 51 per cent in the fourth quarter.
Earlier this year, Tesla lost its place as the world’s leading electric car maker, with Chinese giant BYD overtaking its US rival.
Musk’s firm has suffered two straight years of declining sales, having risen every year for a decade before that.
Tesla also appears to have fallen behind in the development race, with BYD demonstrating a number of technological breakthroughs in recent years.
In 2025, the Shenzhen-based company unveiled a battery capable of charging in the same time it takes to fill up a petrol tank – achieving what industry figures have long referred to as the “holy grail” for electric vehicles.
Tesla sales have also been hit by boycotts of Musk’s firm following his vocal and financial support of US President Donald Trump and other far right politicians in Europe.
In a ranking of America’s 100 most visible companies by Axios Harris, Tesla placed last in ‘character’, and near the bottom for ‘ethics’ and ‘citizenship’.
The Cybertruck has been a particularly polarising vehicle, nicknamed the ‘MAGAmobile’ and ‘Deplorean’ by detractors.
Ahead of its launch in 2023, Musk predicted that Tesla would be selling 250,000 Cybertrucks annually by 2025.
The actual figure was just over 20,000 Cybertrucks sold last year, down from 38,965 in 2024.
