Tesla Spain Sales Jump 112.8% in May; Shares Slip

ANFAC registration data showed Tesla sold 1,690 vehicles in Spain in May, a 112.8% increase from May 2025. The company’s registrations in Spain rose 43.8% in the first five months of 2026 versus the same period in 2025.

The broader electrified vehicle market in Spain, which includes battery-electric and hybrid models, increased 43.6% in January–May 2026, according to ANFAC.

Tesla stock traded about 1.3% lower in premarket trading on Monday. At the same time, futures tied to the S&P 500 were up 0.3% and Dow futures gained 0.4%.

Market participants pointed to comments from OpenAI CEO Sam Altman as a factor in the stock move. On X, Altman wrote, “AI should be able to help people in the physical world,” and said OpenAI is hiring full-stack hardware, operations, systems and machine-learning engineers for a robotics effort. He added that in the long term the company imagines “everyone having a personal robot doing anything they need.”

Tesla has been investing in artificial intelligence projects, including self-driving systems, robotaxis and its humanoid robot program, Optimus. The automaker halted sales of the Model S and Model X to convert production capacity at its Fremont, California plant to humanoid robot manufacturing. Tesla expects to reveal a third generation of Optimus in the coming weeks.

The market for humanoid robots remains small, with relatively few companies selling large numbers of functional units. OpenAI’s hiring announcements indicate an intention to expand in robotics, which could affect competition for engineering talent and manufacturing capacity.
