Musk: Optimus and Cybercab Will Be Tesla's True Value

The Cars Are the Side Hustle Now: Musk's Trillion-Dollar Bet on Robots and Robotaxis

Co-produced by Daniel Aharonoff and DigitalDan

As the chief editor of tesladan.me, I have covered Elon Musk long enough to know that he does not say things by accident. Every few years he drops one of those sentences that quietly reframes the entire Tesla story — "the master plan," "the machine that builds the machine," "production hell." This weekend, on Sunday, October 17, 2026, he dropped another one, in a single post on X: "Optimus and Cybercab will be the vast majority of Tesla's value."

Read that again. Not the Model Y — Tesla's best-selling car on Earth. Not the Semi, not the Roadster, not energy storage. The vast majority of the company's value, in Musk's own words, will come from a humanoid robot and a steering-wheel-free robotaxi that barely exist as businesses today. If you own a Tesla, are thinking about buying one, or hold even a single share of TSLA, this sentence is the lens through which everything else Musk said this weekend — and everything he says on earnings day — has to be read. Let me break it down.

What's the Big Deal? Musk Just Redefined Tesla on a Sunday Night

Here is what Musk actually posted. He argued that only a handful of businesses can scale to "incredible size" — K2 and beyond, in his words — and named them: super intelligence, robots, solar power, and transporting mass into space. Then the kicker: "if you have the first two, the rest will follow."

• The claim: Tesla's humanoid robot Optimus and its Cybercab robotaxi will eventually account for the vast majority of Tesla's value.
• The timing: The post landed late Sunday, just two days before Tesla reports Q3 2026 earnings on October 21 — with analysts looking for $0.43 EPS on $27.90 billion in revenue.
• The market mood: TSLA fell about 7% last week, its worst week in nearly three months, then ticked up roughly 1% overnight on the back of Musk's post.
• The context: The post came days after the Roadster's airborne debut — a car that flipped through the air on cold-gas thrusters in Texas — which Musk defended by saying "Roadster is super cool, so we're doing it anyway."

So what's the big deal? Tesla is currently valued as a car company with tech ambitions. Musk is telling you, in plain language, that this framing is backwards. In his mind, Tesla is an AI-and-robotics company that happens to sell cars today — and the cars are the side hustle funding the main event.

Why You Should Care: 5 Stakes for Investors and Owners

Whether you bought a Model 3 or you're watching the stock, here's what this weekend's statement actually changes:

1. The CEO just told you where to look — and it's not the cars

The valuation thesis: If Optimus and Cybercab really become the vast majority of Tesla's value, then quarterly delivery numbers — even a record like Q3's 486,532 vehicles — are a supporting act, not the headline. Analysts who still model Tesla as an automaker are pricing a company Musk no longer believes in.

2. The October 21 earnings call just became a robot referendum

The question that matters: When Tesla reports Q3 results after the close on October 21, the EPS number ($0.43 consensus) will matter far less than the robotaxi and Optimus updates Musk is expected to give. The shareholder Q&A portal opened October 14 and stays open through October 20 — and you can bet the ranked questions are about Cybercab expansion, FSD, and Optimus. Musk's Sunday post was, in effect, the opening statement.

3. The Roadster is officially a halo car — fun, but not the business

The admission: Musk himself conceded the Roadster isn't one of the world-changing scale businesses: "Roadster is super cool, so we're doing it anyway." A Morningstar analyst echoed the framing this week, calling the flying Roadster a "halo car" that could lure buyers to Tesla's broader lineup — while forecasting fewer than 2,000 Roadster deliveries a year. Meanwhile Musk is floating 400 mph top speeds, Formula 1-beating track times, and autonomous airborne tricks. Exhilarating? Absolutely. A business? Not yet. The Roadster is Tesla's engineering resume; Optimus and Cybercab are its future income statement.

4. The Cybercab scale-up is suddenly the number investors have to justify

The receipts: Tesla says its robotaxi fleet has now exceeded 1 million miles, up from 380,000 miles just six weeks earlier — nearly a 3x jump in a month and a half. Motley Fool commentary this week pegged the Austin fleet at more than 300 Cybercabs, an eightfold increase in about 30 days, with Dallas next in line. Musk's economics have always been the audacious part: a sub-$30,000 Cybercab, rides targeted at around $0.20 per mile, built on the Unboxed manufacturing process. Those are targets, not facts — but the direction of the curve is no longer debatable.

5. The 7% drop last week is the market pricing exactly this risk

The trade-off: Tesla's worst week in nearly three months was the market voting on a simple question: what is this company worth while the robot future is still under construction? Musk's answer — "the vast majority" — is thrilling if you believe the timeline and terrifying if you don't. Every robotaxi mile and every Optimus demo between now and year-end either validates or punctures the Sunday thesis.

Tesla Optimus 2026: The "Vast Majority," Part One

Why would a humanoid robot be worth more than the world's most valuable car company? Because cars are a bounded market and labor is not. Here's the case, as Musk sees it:

• Scale of demand: If a humanoid robot can do factory work, home chores, and dangerous jobs, the addressable market is not millions of cars — it's billions of labor-hours. This is the argument behind the all-time most-viewed post in TeslaDan history: our Optimus coverage from the pre-takeover era still sits at #1 all-time with over 1,700 pageviews, because readers instinctively understand that robots dwarf cars.
• The AI5 tailwind: Our October 3 coverage broke down how Tesla's AI5 chip is being optimized for exactly this — memory cuts that boost Optimus performance. The robot, the chip, and the data all compound each other.
• The $30 billion bet: Back on September 29, we covered Tesla's $30 billion credit facilities aimed at AI infrastructure — the Terafab fab, solar, and robotaxi compute. Sunday's post explains where that money's payoff lives: superintelligence and robots first, everything else after.
• The honest caveat: Musk also admitted this weekend that he spent roughly four months at the White House — longer than planned — and that it diverted his time from Tesla's AI priorities. The robot bet is real; so is the timeline risk.

Tesla Cybercab 2026: The "Vast Majority," Part Two

The Cybercab half of the thesis is further along — and easier to measure:

• Fleet momentum: From 380,000 to over 1 million robotaxi miles in six weeks. More than 300 Cybercabs in Austin alone — an 8x fleet surge in about a month — with Dallas, Houston, and Miami in the expansion picture.
• The economics: A sub-$30,000 purpose-built car with no steering wheel or pedals, wireless inductive charging instead of plugs, and Musk's long-standing ~$0.20-per-mile cost target. If those numbers hold at scale, it undercuts Uber's economics by a factor of several — the same math we broke down in our October 9 Cybercab fleet post, which went on to become one of the most-read stories in TeslaDan history.
• The service march: Robotaxi hours in Austin have now been extended to midnight — the second extension in about two weeks — leaving only a six-hour overnight window before 24/7 service. Each one-hour extension is Tesla proving out nighttime operation, the last real hurdle.
• The cloud: The NHTSA school-zone review opened October 9 covers roughly 1,000 vehicles, and the NHTSA Cybercab audit deadline sits at October 30 — both stories we've covered in depth this month. Regulatory friction is the tax on scaling fast.

What Do the Skeptics Say? The Timeline Question

Let's be honest about the counter-argument, because it's a good one. Musk has a documented history of promising robot-scale futures on owner-scale timelines — Full Self-Driving timelines slipped for years, the Cybertruck's promised $50,000 price never materialized, and "one million robotaxis by 2020" became a punchline before it became, six years late, a fleet crossing a million miles.

The skeptic's version of Sunday's post: Optimus and Cybercab will be the vast majority of Tesla's value eventually — but "eventually" in Musk-time has a habit of arriving two to four years after the announcement. Meanwhile, the cars — the side hustle — have to fund the build-out. Auto gross margins on October 21 will tell you how healthy that funding engine is.

Here's my chief-editor take: the skepticism about timelines is fair, but the direction of travel is the story. Tesla went from tens of robotaxis to over 300 in Austin and past a million fleet miles in six weeks. Optimus is a real robot doing real factory tasks with a real custom chip roadmap behind it. You can doubt the dates without doubting the destination — and on Sunday, Musk made sure you know the destination.

The Road Ahead: October 21 Is the Day the Thesis Gets Graded

So where does this leave you? With a simple homework assignment, courtesy of Elon Musk himself:

• Watch October 21: Tesla reports Q3 2026 earnings after the market close. The numbers — $0.43 EPS, $27.9B revenue consensus — matter. The robotaxi and Optimus commentary matters more.
• Watch the fleet: Can the 1-million-mile curve keep compounding? Does Dallas actually come online next? Is 24/7 service weeks away, as the midnight extension implies?
• Watch the audit: October 30 is the NHTSA Cybercab deadline we've been flagging all month. A clean bill clears the runway; friction doesn't end the story, but it taxes it.
• Watch the robots: Every Optimus demo between now and year-end is a down payment on "the vast majority."

Musk's Sunday post was many things — a shareholder pep talk after a rough week, a roadmap, a dare. But above all, it was an instruction manual for how he wants you to value Tesla from now on: not as the company that sold you 486,532 cars last quarter, but as the company betting that cars were just the warm-up act. As someone who's watched this story unfold for years, I think he's telling the truth about the destination — even if the arrival time is, as always, to be determined.

Stay tuned to tesladan.me for full coverage of the October 21 Tesla Q3 2026 earnings call, where we'll see whether the vast majority of the future starts showing up in the numbers — and in the streets of Austin.
