Tesla Tells Shareholders Optimus V3 Robot Is Ready for Mass Production

Tesla has told shareholders that its Optimus V3 humanoid robot is prepared for mass production, with production lines being developed, according to a company letter sent Monday and highlighted in an SEC filing. The letter, which also confirmed Tesla’s annual meeting for December 3 at Gigafactory Texas, listed Optimus among the company’s 2026 achievements.

The shareholder update and SEC filing carried a message from CEO Elon Musk:

“The most likely outcome is an age of Amazing Abundance, where anyone can have anything they can think of... This is a message of optimism and excitement about the future”.

Tesla has strengthened its public claim about the readiness of its Optimus V3 humanoid robot, describing it as “Readied V3 Optimus for mass-production” in its 2026 shareholder materials filed with the US Securities and Exchange Commission on Monday, October 19.

Previous company guidance has pointed to output beginning before the end of 2026 at Tesla’s Fremont factory, with eventual planned capacity of 1 million robots per year.

The new language follows an October 12 disclosure by Hangzhou-based Xinjian Transmission, a Chinese components supplier linked to the Optimus programme. In a response to questions from the Shenzhen Stock Exchange about its planned IPO, the company said the robot’s hardware design was nearing finalisation, and the project was approaching mass production, according to Chinese financial reporting.

The letter from the company did not provide a production count or a revised timetable, and it also failed to specify a production start date.

However, the letter signed by board chair Robyn Denholm says Tesla continued developing its products and investing in the infrastructure needed to manufacture them at scale, including “the first production lines for Optimus.”

Musk said on an April earnings call that production would likely begin around late July or August, after the Model S and Model X lines at Fremont are dismantled and rebuilt for Optimus.

He cautioned that initial volumes would be “quite low” because the robot has more than 10,000 distinct parts, each of which must enter mass production.

The machines currently coming off the line are not customer units. They are used for internal testing, training and related work, according to reporting from The Information. Production has climbed from a few dozen units a week in the second quarter to several hundred per week in August, but the robot’s hands remain a bottleneck: each hand and forearm contains more than 100 screws and other tiny parts.

Tesla has not confirmed any commercial sales timeline in the shareholder letter.

JPMorgan has said commercial sales are scheduled for the second half of 2027, and Oppenheimer has said Optimus revenue is unlikely before 2029.

The shareholder letter’s language, “prepared for mass production, with production lines being developed,” stops short of saying production has started.

Tesla did not respond to our request for comment on when the first customer units would ship. Grok did respond to our question, and it said:

The gap between “prepared” and “producing” matters for investors who have priced Optimus as a future catalyst.

Tesla’s automotive business is shrinking: fourth-quarter deliveries fell 15% year over year, and full-year deliveries dropped 8%.

The company has guided $20 billion or more in 2026 capital expenditure, a bet that includes robot lines, AI training infrastructure and battery production.

Elon Musk has called Optimus potentially “the biggest product ever”.

Until Tesla discloses customer deliveries, the mass production claim rests on installed lines and internal trials, not revenue.
