Tesla is the most expensive large company in the world by the one measure that is supposed to matter most, and its core business is earning less than at any point in the last four years. Both facts are true at once, and the gap between them is the entire story.

The shares fell from a closing high of $489.88 on 16 December 2025 to $298.32 on 29 July 2026, a drop of 39%. Since then they have climbed back about 18%, to $352.84 on 29 September, without a single new quarterly report. This piece walks through what Tesla is doing now, where its strategic plans and its struggles lie, and what the market is actually paying for. It is built on Tesla's own filings, update decks and earnings calls, and where a number comes from someone else, it says so.

The Premium: Ten Times What Everyone Else Gets

The first thing to understand about Tesla is what its price-to-earnings premium looks like next to the other companies worth more than a trillion dollars.

At the 29 September close, Tesla traded at about 327 times its trailing earnings of $1.08 a share. The next highest is AMD at about 157. The other thirteen profitable $1T+ companies sit between 16 times (Saudi Aramco) and 57 times (Broadcom), with an average of 32.

The arithmetic

If investors paid Tesla the same multiple as the other profitable $1T+ companies, excluding AMD, a share would be worth $17 to $62. It trades at $353. Measured against their average multiple of 32, Tesla is priced about ten times higher, which means only about 5% to 17% of today's share price is explained by what Tesla currently earns.

Tesla is not even the most extreme case in its own family. SpaceX, now worth about $2 trillion and also run by Elon Musk, lost $8.9 billion over the last year, so it has no P/E at all. It trades at about 85 times its sales, against about 14 times for Tesla. Musk's two public companies carry by far the richest valuations of the sixteen companies worth more than a trillion dollars.

When a multiple is this extreme, it has stopped describing current business performance. It is a price for future expectations, and a large part of it is the Elon factor.

This Is Not New

Based on its reported earnings, Tesla's trailing P/E ran between about 563 and 1,128 in 2020. It then fell to about 31 in December 2022 (FullRatio, Macrotrends). The premium swings with belief in the story, not with the income statement.

That is also why the stock is so volatile. It is not that Musk's statements move it on their own. It is that investors value, and judge, his performance so highly that every slipped schedule is punished hard. Call it tough love: when the stock drops on a delayed timeline, the message from investors is that they only react this way because the expectations are that high.

Some investors have been betting on those expectations for years. Cathie Wood's ARK Invest publishes an open financial model of Tesla that values the company at about $2,600 a share in 2029, with about 90% of that value coming from robotaxis alone. Its bear case is about $2,000 and its bull case about $3,100. Even the bear case is roughly 5.7 times the current share price, in a little over three years.

With a premium this large, everything about Tesla is a bet on the future. So it is worth being precise about what the present looks like.

The Car Business: Still the Engine, Losing Its Edge

Tesla is a car company, or at least that is how it started out. About 71% of its revenue still comes from selling fully electric cars: $20.0 billion of $28.2 billion in the second quarter of 2026.

The range is narrow. By deliveries, the Model 3 and Model Y were 97% of Q2 2026 (467,762 of 480,126 cars). Everything else, the Cybertruck and the last Model S and Model X, made up the remaining 3%. The Model S and X ended production in May 2026, and their Fremont line is being turned into the Optimus robot line.

What Is Going Well

480,126Q2 2026 deliveries, a record second quarter, up 25%
~55%North American buyers taking FSD at delivery in Q2
+62%"Other international" revenue growth in a year, to $10.4B
  • Volume is back. Record second-quarter deliveries, the first half of 2026 up about 16%, and the largest order backlog since 2023, according to management on the Q2 call.
  • Tesla still leads the US. Industry estimates put it at about half of all US electric car sales, with the Model Y alone at about a third.
  • It is still efficient. One industry analysis puts Tesla's gross profit per car at about $8,400 in 2025, roughly twice BYD's $4,200.
  • FSD sells cars. About 55% of North American buyers took Full Self-Driving at delivery in Q2 2026.
  • Europe is recovering. From January to August 2026, Tesla's registrations across the EU, EFTA and UK rose 43% to 191,787 cars (ACEA).
  • Prices are holding. Car-sales revenue per delivered car was about $40,000 to $43,000 for five straight quarters despite the cheaper "Standard" trims (my calculation from Tesla's decks).
  • Growth outside the US and China. Revenue from "other international" markets grew 62% in a year to $10.4 billion in Q2 2026, per the 10-Q.

What Is Not Going Well

The volume recovery sits on top of a weaker base. Deliveries fell about 9% in 2025, from 1.79 million to 1.64 million, and the margin on car sales is thin at about 16% excluding credits. Analysts expect Q3 2026 deliveries of about 454,000 to 466,000, roughly 7% below a Q3 2025 that was inflated by US buyers rushing to beat the end of the federal EV tax credit.

Quality has been a problem too. The Cybertruck has been recalled about ten times, and three recalls in 2025 alone covered every Cybertruck built, about 63,600 trucks, some of them several times over (Electrek). And it sells far below capacity: Tesla lists more than 125,000 a year of Cybertruck capacity, but all its "other models" together, the Cybertruck plus the last Model S and X, delivered 12,364 cars in Q2 2026, a pace under 50,000 a year.

The market picture is uneven too. In the US, industry estimates show Tesla's share of electric car sales slipping from about 59% in Q4 2025 to about 50% in Q2 2026, as traditional carmakers discount their EVs. In China, Tesla's sales fell 32% year on year in July 2026, while its Shanghai factory turned into an export base, shipping 295,000 cars abroad in the first seven months of 2026, more than in all of 2025.

Hybrids, the fight Tesla is not in

In the EU, hybrids took 36.6% of the market from January to August 2026, against 21.7% for fully electric cars (ACEA). Tesla makes only fully electric cars. One industry analysis finds that Chinese brands supplied 84% of Europe's market growth this year.

BYD: The Pressure Only Tariffs Hold Back

BYD outsold Tesla worldwide in 2025, 2.26 million fully electric cars against 1.64 million, and 4.55 million once its plug-in hybrids are counted. Inside China, BYD holds about 21% of electric car sales against Tesla's 5%.

In the US, tariffs above 100% keep Chinese cars out. Europe is different. The EU's extra duties on Chinese electric cars (BYD pays 27% in total, Tesla's Shanghai exports 7.8% on top of the standard 10%) do not cover plug-in hybrids, which pay only the standard 10%. BYD has driven straight through that gap: about 70% of its German registrations are plug-in hybrids (electrive). The EU was preparing duties on Chinese plug-in hybrids too in June 2026 (CnEVPost), but for now the result is visible in the registrations.

Part of BYD's price advantage is batteries. Industry estimates put BYD's LFP "Blade" packs at $55 to $65 per kilowatt hour, against $80 to $100 for Tesla's 4680 packs. At the midpoints, that is about 33% cheaper (my calculation).

Four More Headwinds

  • Expired credits. Regulatory credit income fell from $439 million to $146 million a quarter in a year. The main cause is US policy: the 2025 tax law set fuel-economy fines to zero, so other carmakers no longer need to buy Tesla's credits (Electrek).
  • No more US tax credit. The $7,500 federal EV credit for buyers ended in September 2025.
  • Brand damage. In April 2025, amid Musk's political involvement, Tesla's European sales fell 49% while the overall electric car market grew 34% (CNBC).
  • Memory chips. Industry price data show DRAM up 171% in a year as AI data centers absorb the supply (S&P Global), and self-driving cars need far more memory than normal ones.

The Other Business Units

Tesla has more business units that make up a significant part of its revenue, and one of them is its most profitable.

Services: The Fastest Grower

Services and other made about 16% of Q2 2026 revenue ($4.6 billion), grew fastest at 50% in a year, and reached a record 14% gross margin. It is mainly maintenance and charging infrastructure: Supercharging, repairs, used cars, parts and insurance.

  • Charging is a clear lead. Every other North American carmaker adopted Tesla's plug, and Tesla added over 2,400 Supercharger stalls in Q2 alone, 17% network growth in a year.
  • Insurance is the weak spot. It pays out about as much in claims as it collects, a loss ratio of about 100%.

Regulatory credits, reported separately, are now just 0.5% of revenue and collapsing, down 67% in a year.

Energy: The Business That Already Works

Energy generation and storage brought in $12.8 billion over the last year, about 12% of revenue, and more than doubled since 2023. It is also more profitable than cars, at a gross margin of about 29% over the last four quarters. The business is grid-scale Megapack batteries for utilities and data centers, Powerwall home batteries, and solar panels.

But growth has paused this year, and the margin fell from 39.5% in Q1 2026 to 20.4% in Q2. The CFO gave three reasons on the Q2 call: a $240 million warranty charge for faulty supplier cells in older installations, the absence of Q1's more than $200 million of one-off tariff refunds, and falling prices "amidst growing competition". Tesla expects the business to settle in "the mid to low 20% range".

The China problem inside the energy business

The ranking: Tesla lost the global top spot in grid batteries in 2025. BYD took 13% of the market, Tesla 10%, Sungrow 9%, and Chinese companies 76% together (EnergyTrend, Energy-Storage.News).

The rules: to keep their US tax credits, battery projects need at least 55% non-Chinese content in 2026, rising to 75% by 2030 (Morgan Lewis).

The supply: Tesla still buys most of its cells from China, in its CFO's words. Its own LFP (lithium iron phosphate) cell plant in Nevada started this year but can make just 7 gigawatt hours a year, against 46.7 GWh of batteries Tesla delivered in 2025. That is why it also signed a $4.3 billion cell deal with LG Energy Solution, with deliveries from a US plant starting around August 2027 (Energy-Storage.News).

FSD: Already Shipped, Not Reported

Full Self-Driving is already on sale, but its revenue is counted inside car sales, so Tesla does not report it. About 1.5 million people pay for it (1.48 million active subscriptions in the Q2 2026 deck), now mostly as a $99 monthly subscription. It is growing, 56% in a year. But BYD, Tesla's biggest global competitor, gives its own version, "God's Eye", away as standard, and says it was running on over 3 million cars by May 2026 (The Driven).

Nor has FSD become the industry's operating system. Musk has offered to license it for years, and no carmaker has taken it up. In March 2026, Nvidia instead signed Hyundai, Nissan, Isuzu, BYD and Geely to its self-driving platform (CNBC). It is an Apple versus Android split: Tesla's system runs only on Tesla's cars, while everyone else buys the brains off the shelf. Tesla's answer is data, with customers close to 10 billion FSD miles by April 2026, and cost, with a camera-only system on its own chip.

New Car Models: Very Few

The only new versions so far are the cheaper "Standard" Model 3 and Model Y, plus the new Roadster, whose reveal moved to 15 October because of weather (Electrek). Reuters reported in April 2026 that a cheaper compact SUV is in early development, not before 2027 (Electrek). Tesla has not confirmed it. Asked about a compact car on the Q1 call, Musk answered that the Cybercab is the compact vehicle.

New Products on the Horizon

FSD, the Long-Term Version

The real prize is unsupervised self-driving in customers' own cars, which Musk expects "probably in the fourth quarter" of 2026. That promise has a history, and the approvals are slipping: Europe's vote moved to December 2026 or later, and China is uncertain.

The safety regulator is also looking at the software already on the road. NHTSA upgraded its investigation into how FSD handles low visibility to about 3.2 million cars, covering nine crashes and one death, which is one step from a possible recall (Electrek).

Robotaxi and Cybercab

The two names are easy to confuse, and Musk has apologised for it. Robotaxi is the ride-hailing service. The Cybercab is the two-seat car built for it, with no steering wheel or pedals. In Musk's words, "this car either drives itself or it does not drive."

7US metros with Robotaxi service, driverless in 6
380,000Unsupervised miles, with "zero notable incidents"
~500,000Paid rides a week at Waymo, the leader

Tesla will run the fleet itself and compete with Uber and Waymo: "We expect to be vertically integrated with Robotaxi," Musk said on the Q2 call. The Cybercab has been in production since the second quarter of 2026 and launched publicly in Austin on 3 September.

The economics are built on utilisation. Musk expects the Cybercab to be used "probably 50 or 60 hours a week, instead of the 10 or 11 hours a week" of a privately driven car. The CFO plans to finance the fleet with bank loans against its steady cash flow, and owners could add their own Teslas to it, "kinda like how Airbnb works", in Musk's words. That is a shift from selling products to renting out usage, with the machines, their charging, cleaning, insurance and liability all on Tesla's balance sheet. It is also part of why Tesla lined up $30 billion of borrowing.

The quiet change six weeks before launch

The Q1 2026 update said: "Cybercab, Tesla Semi and Megapack 3 are on schedule for volume production starting in 2026." The Q2 update, published on 22 July, says only that "Tesla Semi and Megapack 3 remain on schedule for production starting in 2026", citing battery cell constraints. The Cybercab was quietly removed from the 2026 volume plan six weeks before its public launch. The stock rose 5.4% on launch day and fell 5.9% the day after (CNBC).

Regulators are the next hurdle. NHTSA, the US National Highway Traffic Safety Administration and the federal car safety regulator, ordered Tesla to answer 21 questions under oath by 30 September on how a car without a steering wheel or pedals meets safety rules written for human drivers (NHTSA). If Tesla is forced onto the exemption route that Amazon's Zoox took, output could be capped at 2,500 cars a year. Musk knows how fragile this is: "If we injure even one person, it'll be worldwide headline news, and regulators will immediately clamp down."

Then there is price. On launch day, a Cybercab ride cost 51% more than Uber for the same trip, $19.58 against $12.96 (Austin American-Statesman). Musk's long-term target is 20 cents a mile, 86% less than the $1.40 a mile Tesla charges today.

A Global Race Tesla Is Behind In

  • Waymo does about 500,000 paid rides a week with about 3,800 cars, by its own figures, and aims for a million weekly rides by the end of the year (TechCrunch).
  • Baidu's Apollo Go in China did about 300,000 weekly rides by February 2026 (CnEVPost).
  • Pony.ai and WeRide each run about 2,000 robotaxis.
  • Tesla does not report a fleet count. Analysts on the Q2 call put it in the dozens of cars per city.

There is a technology difference too. Tesla insists on cameras only. Every competitor operating at higher volumes, Waymo, Baidu, Pony.ai, WeRide and Zoox, combines cameras with lidar and radar (Not a Tesla App). If camera-only systems prove harder to certify, that choice could become a technological or even a regulatory limitation.

Optimus

Musk calls the humanoid robot the biggest product ever. The Fremont line is being rebuilt for a million robots a year, but Optimus version 3 still has not been shown, and production has not been announced. First sales outside Tesla are expected in 2027.

Meanwhile China is already shipping. One research firm counts 19,100 humanoid robots shipped worldwide in the first half of 2026, up 272%, with 97% of them Chinese (Smart Analytics Global). Musk himself calls China "by far the biggest competition" in robots.

Unitree's G1 costs $13,500, below Tesla's own $20,000 to $30,000 target, and Chinese humanoids already sell from about $4,300 for Unitree's R1-D to about $100,000 for the H2 Plus (RobotSourced, Robot Price Index).

The Semi

Series deliveries of the Semi truck started on 25 September 2026 in Nevada, with PepsiCo, DHL and US Foods among the customers (electrive). That is almost nine years after it was unveiled, and it arrives with the largest US electric truck order so far: the ZET SCALE alliance named Tesla for 2,500 trucks. But it is late. Volvo had already sold 5,000 electric trucks by April 2025.

The Roadster

The second-generation Roadster was unveiled at the same November 2017 event as the Semi, and its production version is due to be revealed on 15 October 2026, moved from 1 October because of weather (Electrek). Tesla still advertises 0 to 60 mph in 1.9 seconds, more than 250 mph and 620 miles of range, but it has removed the 2017 prices of $200,000 and $250,000 for the Founders Series without publishing new ones, and production at Gigafactory Texas is targeted for 2027 or 2028 (CarsDirect). Unlike the Semi, it is still a reveal, not a delivery.

The Pipeline and the Early Ideas

In the pipeline

Megapack 3 and Megablock: next-generation grid batteries (5 MWh units, or 20 MWh blocks of four) from the new Houston factory.

Solar: a new Tesla solar panel made in Buffalo, and a plan for 100 gigawatts a year of solar cell production.

Early ideas

Digital Optimus: an AI that operates computer screens the way FSD drives a car, managed by SpaceX's Grok.

Megapods: Tesla AI computers placed at Supercharger sites, which have about 7 GW of power connections, to add computing where the electricity already is.

What Is Driving Capex Without Products

Capex will be over $25 billion in 2026, including a record $5.8 billion in Q2 alone, and the CFO says it will keep growing for another two to three years.

On 29 September Tesla signed $30 billion of bank credit: a $20 billion three-year delayed-draw term loan plus $8 billion and $2 billion revolving facilities. None of it has been taken, and Tesla says it does not plan to draw on it in 2026 (8-K). If operating cash flow stays at the first half's pace and capex hits the $25 billion guidance, Tesla ends 2026 with roughly $35 billion of cash, down from $43.5 billion at the end of June (my calculation).

Much of this money is not building products at all. It is building internal efficiency and supply chain security. As the CFO put it on the Q4 2025 call: "all this comes out of necessity."

1. The battery chain: built out of desperation

Tesla is building a lithium refinery and a cathode plant in Texas because it depends on Chinese batteries: the energy business buys "most of the battery cells" from China. Tariffs on Chinese imports cost Tesla over $400 million in Q3 2025 and over $500 million in Q4. It needs domestic battery production in the US just to meet demand without excessive costs, and to keep US tax credits for its customers, which now require non-Chinese content.

Musk on the Q4 2025 call: "We build them out of desperation." Together with the LFP plant and the 4680 cells, the whole battery chain is for Tesla's own cars and batteries, not for sale.

2. Terafab: chips, because Optimus needs them

Musk on the Q4 2025 call: "Optimus is completely useless without an AI chip." He expects chips, and especially memory, to cap Tesla's growth in three to four years. So Tesla is building a roughly $3 billion research fab in Texas, and a $16.8 billion first phase of the full-size Terafab together with SpaceX, targeted for completion by the end of 2028 (TechCrunch). County filings put the total across all phases at up to $119 billion. It is for internal use, not an NVIDIA competitor: Musk says Tesla will need all its chips itself.

3. AI computing: the first line of the capex

The 10-Q names AI computing first among the capex drivers. Tesla more than doubled the computing power of its Cortex data centers in Texas in the first half of 2026. Cortex 1 runs at over 90 MW and Cortex 2 at over 115 MW. They train FSD and Optimus, so today they are a cost, not a product.

The Crash, Summarised

The 39% fall from about $490 in December 2025 to about $298 in July 2026 was a combination of three things:

  • High capex that does not lead to immediate revenue.
  • Underdelivering on promised timelines. Robotaxis in 8 to 10 metros by the end of 2025 became 7 by July 2026. The Optimus V3 reveal kept slipping. The EU and China FSD approvals were delayed. And on the Q1 2026 call, Musk admitted that Hardware 3 cars, many with FSD already paid for, can never drive themselves unsupervised. Owners are offered discounted trade-ins, or computer and camera swaps in new small local factories.
  • Severe pressure from China on the main business: cars.

The trigger was the 22 July results. The stock fell 14.5% the next day, from $374.01 to $319.69, and hit its low a week later.

$28.2BRecord Q2 revenue, up 26%
-57%Operating profit, to $398M, a 1.4% margin
$0.33Adjusted EPS, against $0.51 to $0.53 expected
-$1.1BFree cash flow, as capex more than doubled

Revenue was a record, but the profit was not there. Official net income of $1.11 billion looked respectable only because of a $1.0 billion paper gain on Tesla's SpaceX stake and a $274 million tax benefit. Free cash flow turned negative, and on the same call the CFO announced plans to borrow up to $30 billion. The same update quietly dropped the Cybercab from 2026 volume production.

At the peak: Q3 2025 results

Revenue of $28.1B, operating profit of $1.62B (a 5.8% margin), and a record $4.0B of free cash flow on $2.2B of capex. Musk said he was "100% confident" that Tesla can solve unsupervised Full Self-Driving, and promised robotaxis in 8 to 10 metros by the end of 2025.

At the low: Q2 2026 results

Revenue of $28.2B, almost exactly the same, but operating profit of $398M (a 1.4% margin) and free cash flow of minus $1.1B on $5.8B of capex. Robotaxi in 7 metros, approvals slipping, and up to $30B of borrowing lined up.

Sales did not crash. Profit and cash did, because the cost of the plan arrived in the results for the first time.

There was a policy hit on top. The 2025 US tax law scrapped the fuel-economy fines that made other carmakers buy Tesla's credits, and ended the $7,500 EV tax credit. And energy, the bright spot, saw its margin fall from 39.5% to 20.4% in a single quarter, on a $240 million charge for faulty supplier cells, the absence of Q1's one-off tariff refunds, and falling prices.

The punishment has its limits. The stock has recovered about 18% since the July low on exactly the same financial results, which means the rebound is a change in mood, not in the numbers. At about 327 times earnings, investors have not given up on the bet. They have marked the price down while they wait. Short sellers hold only about 2% of the shares, options traders are leaning bullish, and the next catalysts are close.

The SpaceX Affair

SpaceX merged with xAI, Musk's AI company, in February 2026 at a combined valuation of $1.25 trillion, then raised $85.7 billion in June in the largest IPO ever (Wikipedia). Rumours of a Tesla merger have followed, because both are led by Musk and the overlaps are everywhere.

Synergies and Related Transactions

  • A SpaceX stake: Tesla owns less than 1% of SpaceX, from a $2 billion investment in xAI. It gained $1 billion in Q2 and made up most of Tesla's profit that quarter. Shareholders never approved it: the advisory vote failed in November 2025 because abstentions count as votes against, and the board invested anyway.
  • Grok: SpaceX's AI is in Tesla cars and will manage Optimus and Digital Optimus.
  • Starlink: being built into all Tesla cars, starting with the Cybercab.
  • Terafab: a joint chip factory, with a $16.8 billion first phase.
  • Megapacks: SpaceX bought $405 million of them in the first half of 2026.

Who Does What

Tesla: the ground

Cars, robots, batteries and solar, built in the millions or in gigawatts, and the small AI that runs on the device. Musk says Tesla's models are only about 5% to 10% the size of Grok, because they have to fit on a cheap chip and work offline. Tesla's AI is the "worker" that drives and moves in real time.

SpaceX: space and the big AI

Rockets, satellites and Starlink, plus Grok, Cursor, and the Colossus data centers, the first of which it rents to Anthropic for $1.25 billion a month. SpaceX's Grok is the "manager" that plans and talks, in the cloud.

Where the split makes no sense: both run AI data centers (Tesla's Cortex, SpaceX's Colossus), both do AI and manufacturing, and every overlap is a related-party deal that needs both boards' approval. And the high-end AI creates more value. Anthropic's rent and Cursor, bought for $60 billion in stock, go to SpaceX shareholders, not Tesla's. Musk's attention is split too: the Tesla and SpaceX boards now compete for him with pay packages (CNN).

Why I expect a merger

A merger would combine two $1T+ companies, which is unprecedented. I expect it because Musk loves recognition and wants to run the biggest company in the world, and a merger is the fastest step toward that spot. At about $3.5 trillion, the combined company would still rank fifth, behind NVIDIA, Apple, Alphabet and Microsoft (StockTitan), but it would be one company instead of two.

Asked on the July call, Musk would only say: "It's got to be done with the appropriate process." The SpaceX IPO is the perfect preparation. It gave SpaceX a public share price that can set the swap ratio, which Morningstar calls "a practical prerequisite" (StockWireX). With the larger valuation, SpaceX would be the buyer, issuing about 94% more shares to acquire Tesla (Fortune).

The Vision for Tesla

What is the strategy? To move away from selling cars and become a provider of intelligence through services. Tesla says so itself. Its Q2 2026 10-Q opens: "We are focused on bringing artificial intelligence into the real world, through products and services like FSD (Supervised) and Robotaxi, as well as working to develop and commercialize AI robots (including Optimus)."

Musk's pay package is the clearest blueprint for that strategy. Approved in November 2025 with about 77% of the votes cast (CNBC), it grants up to 423,743,904 shares in twelve tranches of about 1% of Tesla each. Control was the point for Musk. On the Q3 2025 call he said: "My fundamental concern with regard to how much voting control I have at Tesla is, if I go ahead and build this enormous robot army, can I just be ousted at some point in the future?" Tranche N needs a market value from $2 trillion (the first) to $8.5 trillion (the twelfth), plus any N of twelve operational milestones (award document):

  1. 20 million Tesla vehicles delivered. Easy: Tesla has already delivered 9.7 million, 49% of the target, and sells about 1.75 million a year.
  2. 10 million active FSD subscriptions. The real strategy: only 15% delivered, at 1.48 million.
  3. 1 million bots delivered. The real strategy: 0% delivered.
  4. 1 million robotaxis in commercial operation. The real strategy: under 0.1%, since Tesla does not report a fleet count and analysts say it runs dozens of cars per city.
  5. Milestones 5 to 12: adjusted EBITDA of $50 billion, $80 billion, $130 billion, $210 billion, $300 billion, and then $400 billion three times, each over four consecutive quarters and the three $400 billion periods not overlapping. Tesla made $15.3 billion over the last four quarters, so these are 3 to 26 times today's level.

The strategy is clear: more profit from products beyond cars. Stop being a car company and become an AI, robotics and automation company. FSD and the robotaxi signify the same shift: get paid for a high-margin service on top, not just for low-margin hardware. The car business is under immense pressure, so Tesla is innovating in a new direction, and even Optimus robots might one day be rented as a service or come with heavy subscription components.

The $400 Billion Question

What is interesting is that energy and the other business units have no milestone of their own in the product volumes, although their profit counts toward EBITDA. And cars plus FSD alone could never reach $400 billion of EBITDA, so investors are expecting the robotaxi and Optimus to carry Tesla to the profit milestones.

I ran the numbers with every assumption set in Tesla's favour: the 2022 peak profit per car of at least $13,400 (from SEC data), FSD counted as pure profit at $99 a month, half of all Teslas on the road subscribing, and no car ever scrapped.

~$39BCars plus FSD at today's 1.75M cars a year
~$62BEvery factory full, 2.4M cars, 16M FSD subscribers, plus energy and services
~$252BToyota-scale car sales plus ten times today's energy business

To reach $400 billion with cars and FSD alone, FSD would have to cost about $1,900 a month instead of $99, or Tesla would need to sell about 25 million cars a year, roughly two and a half times the roughly 10 million a year that Toyota, the largest carmaker, sells. So even when selling 2.4 million cars a year with 16 million FSD subscriptions, reaching $400 billion would require about 7 million robotaxis on the road and 30 million robots sold a year.

What the scenarios show

The milestones do not add up to the target. Hitting the package's own "1 million robotaxis" and "1 million bots" adds only about $30 billion a year.

Musk's price target works against his profit target. At 20 cents a mile, a robotaxi earns about $6,000 a year, so closing the gap with robotaxis alone would take about 56 million of them.

Optimus has to carry most of it. Robots alone would need about 45 million sales a year, inside Musk's own "maybe 50-100 million units" for version 5, against 19,100 humanoids shipped worldwide in the first half of 2026.

These are my calculations. The utilisation (60,000 robotaxi miles a year) and the margins (50% on robotaxis, 30% on a $25,000 robot) are assumptions; the prices and volumes come from Tesla and Musk.

Musk himself warns how hard the robot side is. "This is going to be the hardest product to scale manufacturing that we've ever made at Tesla, because everything on the robot is new," he said on the Q2 2026 call. On the Q1 call he said the Optimus production rate "is impossible to predict", because with 10,000 unique parts, the ramp "will move as fast as the least lucky, slowest, dumbest part in the entire 10,000".

My view is that the only way to reach the top EBITDA milestones is with new products or services that are not predictable yet.

In Musk's Own Words

I think Optimus will be our biggest product, not just Tesla's biggest product ever, but probably the biggest product ever.

He calls Optimus "the infinite money glitch", with a million-a-year line in Fremont, 10 million a year for version 4, and "maybe 50-100 million units" for version 5. On robotaxis, he expects Tesla to make "several times more Cybercabs per year than all of our other vehicles combined", and says that in the future "probably less than 5% of miles driven" will be by a human driver.

We now emphasize FSD as a product and vehicle as only the delivery mechanism.

Conclusion

Investors love Elon, which is why Tesla carries a massive P/E premium. But they also expect a lot in return: meeting timelines, dominating industries, and constant innovation.

The case against

The car business is recovering in volume, but margins are thin and the competition is very strong. Capex is at a record, and much of it builds supply chains rather than new products. Tesla is priced on an unproven strategy, robotaxis and Optimus, and on today's earnings only about 5% to 17% of the share price is explained.

The case for

Tesla has built markets before: mass-market EVs, the Supercharger network and grid-scale batteries, now a $12.8 billion business. It has $43.5 billion of cash plus $30 billion of undrawn credit, a working driverless service in six cities, and what the research files describe as the only lithium refinery in the US. The shareholders gave Musk a package that pays only if the new businesses become enormous.

That means investors lack evidence, which explains the volatility. The pattern is visible in Tesla's own history: across its last 13 big events, the stock beat the market in the month before 9 of them and trailed it the day after 9 of them, usually when a demo pushed real delivery further out.

I think the stock will do very well in the long term, and it will likely spike whenever Tesla makes visible progress on its vision. The next tests are close: Q3 deliveries on 2 October, NHTSA's review of the Cybercab, the Roadster demo on 15 October, Q3 earnings in late October, and the EU's FSD decision in December.

The growth may also come from somewhere else entirely. Tesla could, for example, pivot from the humanoid to a different type of robot with mass-market appeal, and that could become a major growth driver.
