Tesla Starts Optimus Robot Production as Quarterly Profit Falls 43%

Tesla has begun producing its Optimus humanoid robot at its Fremont, California factory, the company announced Wednesday — even as its third-quarter profit fell 43% to $787 million.

The Fremont manufacturing space, previously dedicated to electric vehicles, is now turning out what Tesla calls its first market-ready robots. "The bots coming off this line are the first production-quality bots that we have manufactured," Tesla wrote in its third-quarter shareholder letter. The company added a caveat of its own: "While we will continue to iterate on the hardware and manufacturing process, we have proven that the current manufacturing process for Optimus is suitable for a commercial product."

That admission matters. Suitable for a commercial product is not the same as a finished product, and Tesla itself says the hardware and process will keep changing.

What happened to profits?

Net income dropped to $787 million from $1.37 billion in the same period of 2025 — a decline of $583 million in a single year. Tesla pinned the fall on soaring expenses tied to Optimus, artificial intelligence projects, and autonomous driving, plus lower regulatory credit sales.

Revenue offered no cushion. Total third-quarter revenue came in at $28.04 billion, marginally below the $28.09 billion from the third quarter of 2025 and roughly $200 million under the previous quarter's $28.23 billion. In plain terms: Tesla's top line is moving sideways.

The company stayed profitable largely because of one segment. Its "services and other" category delivered a record $734 million in gross profit — nearly matching the quarter's entire net income. Strip that out, and the robot-and-AI spending bite looks considerably worse.

How did each business perform?

• Vehicles: Revenue was flat year-over-year at $20 billion. Tesla delivered 486,532 vehicles in the quarter, about 6,000 more than the previous quarter but fewer than in the same period last year.
• Energy: Solar and energy storage revenue fell 16% year-over-year to $2.8 billion, which Tesla blamed on tariff-related customer refunds.
• Services: The category that includes Full Self-Driving subscriptions grew 33% year-over-year to $4.6 billion — the only segment showing meaningful expansion.

The pattern is clear. The legacy EV business is treading water, energy is shrinking, and subscription services are carrying the profit load while Tesla absorbs heavy research spending on robots and AI.

What does the Optimus milestone actually mean?

Tesla frames the Fremont line as proof that Optimus can be built at commercial scale. The shareholder letter's own language — "we will continue to iterate" — signals the robots rolling off the line today are not the final design. Tesla disclosed no production volume targets, delivery dates, or pricing for Optimus in the announcement.

The company also did not break out how much of its spending increase went specifically to the robot program versus AI and autonomous driving. Without that split, investors cannot judge which bet is consuming the most cash.

What the quarter shows is a company at the midpoint of an expensive wager: flat revenue, a 43% profit decline, and a services segment working overtime to keep the company in the black. Whether Optimus justifies that cost depends on production scaling Tesla has yet to quantify.
