Tesla converts Fremont California factory to humanoid robot production Q2 2026 — phasing out Model S + Model X assembly lines for Optimus, target one million units per year at full capacity
Tesla declared it will convert its Fremont California factory to humanoid robot production in Q2 2026 — phasing out the Model S and Model X assembly lines to build a robotics plant targeting one million units per year at full capacity. Initial production expected to begin late summer 2026. The capacity commitment represents substantively larger humanoid manufacturing scale than current industry baselines.
The substantive piece is the million-unit-per-year capacity target as category-transforming commitment. Pre-Fremont-conversion humanoid manufacturing capacity operated at thousands-to-low-tens-of-thousands per vendor (Figure BotQ 12K units/year, others substantially lower). Tesla's one-million-units-per-year target represents two orders of magnitude higher manufacturing scale. If executed at announced scale + timeline, Tesla becomes overwhelming category supply leader.
The competitive read against Figure's operational-validation evidence at BMW Spartanburg is that the H2 2026 humanoid category has two competing trajectory frames: operational-validation-first (Figure model — prove capability, then ramp manufacturing) versus manufacturing-capacity-first (Tesla model — commit massive manufacturing, validate during ramp). Both trajectories have execution risks; which produces better H2 2026 to 2027 humanoid category trajectory is uncertain.
