Vehicle demand stalls against a cheaper Chinese field, FSD approvals slip country by country, Robotaxi stays confined to a handful of metros, and Optimus does not sell externally inside the horizon. Storage keeps working.

News · Tesla's Largest Semi Order Is 500 Trucks. Nevada Could Build That in Four Days. Einride's 500 trucks are the largest Semi order, and the public book is roughly 1,500 — against a factory guided to thousands this year, 50,000 at nameplate.

Class 8 electric trucking out of the Nevada line. Higher ASP than cars and a real order book, but still a secondary volume story inside the horizon.

Price per unit $180000 drifting −0.8% per quarter $180k a unit. Higher than a car by a wide margin, which is why modest volume still shows up.

Assumptions & reasoning

  • Semi revenue is NOT disclosed by Tesla — this line is apportioned like every other, and the unit count is derived from it at a $180k average. Deliveries before 2026 were a pilot fleet in the tens per quarter (PepsiCo and similar), so 2025 here is deliberately near zero; the Nevada high-volume line is what starts the ramp.
  • Margin starts negative. A ramping line carries fixed cost against low volume, and Tesla has never claimed Semi is profitable at current output.
  • Volume compounds at 18% until it reaches the Nevada line's stated ~50k a year and then holds there. Left unbounded the same rate reached three times the line's design capacity over five years, which is not a view about demand — it is a modelling error. Raise the ceiling if you think a second line gets built.
  • Autonomy is not modelled here. Driver-out trucking would change the economics of this line more than any volume assumption, and it is not in the numbers.
