Tesla's Q3 2026 earnings update confirmed early Optimus production on high-volume Fremont lines, with the first production-quality humanoid units rolling off as the company repurposes former Model S/X space. Elon Musk described the ramp as slow and bumpy due to ongoing design iterations, supply-chain issues, and unresolved challenges in dexterity (especially hands), AI for open-ended tasks, reliability, and durability. He set external deliveries around late 2027 after AI5 chip integration planned for April and a training fleet buildout. A near-term unscripted demo video is expected within weeks, but no pricing, public preorders, or consumer availability has materialized. These verified manufacturing milestones and explicit timelines anchor trader sentiment on near-term release probabilities.
