The entire foundation of Elon Musk’s technological empire rests on a tiny chip named AI5, which is set to power Tesla’s Full Self Driving mode, Optimus robots, and data centers. Musk has been talking about the chip for more than a year now, but now the timeline to commercial scale has slipped…significantly.
Musk first announced that Tesla had “completed design” on the AI5 chip—originally called the Hardware 5 chip—last year at a June 2024 Tesla shareholder meeting, noting that “AI 5, will be in Optimus and in all cars in about 18 months.”
Well, it’s been almost 18 months. Where’s the chip?
Still in design review apparently.
Musk posted on X on November 15 that, “Just wrapped up the AI5 Saturday chip design review a few hours ago. We’re starting to do some work on AI6 too,” adding, “Btw, AI5 will not be available in sufficient volume to switch over Tesla production lines until mid 2027, as we need several hundred thousand completed AI5 boards line side.”
Mid-2027?
What the Delay Means for Tesla—and Musk’s Other Companies
Morningstar notes that, “All of Tesla Inc. depends on making a tiny silicon chip that will power everything from driverless technology to robots.”
The delay means that major upcoming products, like the Cybercab, the highly anticipated robotaxi planned for 2026, will debut using the current AI4 hardware instead of the new AI5 chip.
This means Tesla’s flagship autonomous taxi will essentially operate with the same computing brain as a Model 3. As a result, it will almost certainly require a steering wheel, remote human oversight, operational limits similar to competitor Waymo.
It also means that the Cybercab will likely be confined to tightly geofenced areas until upgraded hardware becomes available.
And that’s if 2027 is a realistic new deadline. A move from mid 2025 to mid 2027, in Elon-speak, often implies a much longer horizon.
Musk floated the idea of building a chip production facility to scale production at a November 6 shareholder meeting: “Even when we extrapolate the best-case scenario for chip production from our suppliers, it’s still not enough,” Musk said at the Nov. 6 annual meeting. “I think we’re probably going to have to build a gigantic chip fab.” But Morningstar notes that it can take 5-7 years to build such a facility.
What does this mean for Tesla’s future?
Tesla’s valuation which rests heavily on technology rather than automotive fundamentals. That means the company’s perceived technological lead is in many ways more important to its valuation than its actual technological lead.
You only need to look at Tesla’s 274 price to earnings ratio versus Toyota’s 8.5 to infer that investors tend to treat Tesla as a technology company rather than an automotive company.
Elon Musk reinforces that perception every chance he gets. When earnings disappoint, he pivots the conversation to autonomy, chips, data centers, and robots with unlimited market potential.
So what happens next?
Will competitors use this window to showcase taxis and robots that appear similarly capable? What will this mean for Tesla’s perceived technological lead?
It is difficult to predict… because Musk remains one of the most persuasive storytellers and futurists in business. But this small announcement about a small chip could have unusually large consequences.
Tesla’s stock has always been the company’s fuel. It let Musk finance every ambitious project because the market values Tesla on what it might become, not what it is now. As long as he nudges timelines forward without breaking the spell, belief stays intact and Tesla floats above the entire auto industry in value.
This time the promise is different. You can delay autonomy and robots. You cannot delay the physics of making chips. Semiconductor production is visible to the entire supply chain. TSMC, Samsung, ASML, everyone can see exactly what Tesla is or is not building. There is no way to fake progress here.
Musk knows this, which is why he wants Tesla to become a chip maker. But that path takes years and follows a pace set by the entire global semiconductor ecosystem, not by narrative or ambition.
So the question is simple. How long before Tesla’s market cap, the engine of every dream so far, starts to wobble. This time the future comes with a timestamp. And the world can read it.
