“We're going to be building a million-unit Optimus production line, hopefully with the production start towards the end of next year [2026].”
Deadline is end of 2026. Tesla decommissioned the Fremont Model S/X lines in May 2026 and began converting them for a line designed for 1 million robots/year, but start of production had slipped from 'late July or August' to 'later this year' as of the Q2 2026 update.
