Tesla Just Started Building Its Robot. Here's When You'll Actually See One.

Tesla's humanoid robot is officially coming off an assembly line. Just not very many of them, and not for you yet.

On Wednesday night's earnings call, Elon Musk said Tesla has "started like what I'd call early production" of its Optimus robot on a high-volume line in Fremont, California, the plant that used to build the Model S and Model X.

Tesla says these are "the first production-quality bots" it has made. And most of a production line built to make 1 million robots a year is already in the building.

The stock didn't celebrate. Tesla (TSLA) was down about 2.5%, near $377, in afternoon trading.

The catch: the hands

Musk was unusually candid about what still doesn't work.

The hardest part is the hand. A Tesla engineer called it "one of the most challenging hardware areas." Fingers have to be gentle enough to pick up something delicate, yet tough enough to survive constant wear. Unlike skin, they can't heal.

The robot's durability and its AI also need more work. Musk said he expects those problems "to be solved around the end of next year."

That sets the timeline:

• Around April 2027: Tesla's next-generation AI chip goes into Optimus.
• Late 2027: Tesla starts delivering robots to other companies. The first jobs will be dangerous, repetitive factory work.
• Later: robots for homes, "eventually," as production grows.

Getting to 20,000 robots a week will take "probably at least a year, maybe a little longer," Musk said.

Why the timeline matters

Musk has been here before. In 2024, he said Tesla hoped to sell Optimus to other companies in high volume in 2026. In early 2025, he said Tesla would build about 10,000 robots that year. Neither happened.

This time the promises are smaller and the robots are real. That's progress, but it's also a reminder to treat robot dates as goals, not guarantees.

Tesla isn't alone

The race to build working humanoid robots is crowded:

• Boston Dynamics, owned by Hyundai, started making its electric Atlas robot in January. Hyundai plans to put 25,000 robots to work in its plants over the next few years.
• XPeng, a Chinese carmaker, plans to start mass-producing its robot at the end of 2026.

What it means for you

• If you own Tesla, you own a robot bet. Much of Tesla's value comes from investors betting on robots and self-driving cars, not just cars. Wednesday's update kept that story alive, but pushed the payoff further out.
• If you own an S&P 500 fund, you own a little Tesla too, so this matters a bit for you either way.
• The bigger trend is real. Big companies are spending heavily to put robots on factory floors. The winners may include the companies that make the chips, motors and sensors inside them, not just the robot makers.

What to watch

Musk promised a video within a month or two showing Optimus doing tasks it wasn't programmed for ahead of time. That will be the first real test of whether the robot's brain is catching up to its body.
