SpaceX CEO Elon Musk says that the company could eventually develop an expendable version of its next-generation Starship rocket.
Starship is extraordinarily ambitious. Even before considering the unproven concepts of orbital propellant refilling and full, rapid reusability that are central to the full system, Starship is a beast. The rocket measures 120 meters (~390 ft) tall and is theoretically capable of producing up to 7590 tons (~16.7M lbf) of thrust at sea level. It’s larger, taller, heavier, and more powerful than any other launch vehicle in history. 33 Raptor 2 engines power Starship’s Super Heavy booster – also more than any other rocket.
Once optimized, SpaceX says that Starship can launch up to 150 tons (330,000 lbs) to low Earth orbit while still recovering the orbital ship and suborbital booster for reuse. CEO Elon Musk has stated that Starship reuse will eventually take hours, enabling multiple flights per day for each ship and booster and dropping the marginal cost of each launch to just a few million dollars.
In comparison, SpaceX’s workhorse Falcon 9 rocket uses simpler Merlin 1D engines, has just 10 of those engines to Starship’s 39 Raptors, produces about 10 times less thrust at liftoff, and can launch about 11% as much payload to orbit while expending its upper stage. Even then, Musk reported in mid-2020 that the marginal cost of a Falcon 9 launch was $15 million – impressively low but still a vivid demonstration of just how far Starship has to go.

The update that's rolling out to the fleet makes full use of the front and rear steering travel to minimize turning circle. In this case a reduction of 1.6 feet just over the air— Wes (@wmorrill3) April 16, 2024
Simply ensuring that Starship can reach orbit at all is a major challenge. Successfully recovering Starship and Super Heavy after the fact may be an even bigger challenge and cannot be fully demonstrated until the rocket can consistently reach orbit. SpaceX won’t be able to reuse Starship until it can consistently recover ships and boosters from orbital launches. And there’s no guarantee that early prototypes will be reusable even if they’re recovered.
Until reusability is demonstrated, every “Starship upper stage” will be functionally expendable whether or not Elon Musk wants it to be. Musk likely means that SpaceX may or may not decide to develop a Starship upper stage custom-built for expendable missions. Such a stage would likely take Starship, remove everything extraneous, and reduce its mass as much as possible. Musk has proposed something similar before, noting that SpaceX could develop a “lightened” version of Starship “with no heat shield or fins/legs” for expendable, interplanetary launches.

Further to the contrary, SpaceX’s Starbase factory is already building multiple intentionally-expendable Starships. Ship 26 and Ship 27 feature no thermal protection, have no heat shield tiles, and will not be fitted with flaps, making them impossible to recover or reuse. More likely than not, they will be used to test other crucial Starship technologies like orbital refilling and cryogenic fluid management.
Meanwhile, SpaceX’s multibillion-dollar contract to use Starship to return NASA astronauts to the Moon revolves around a depot ship variant that will store propellant in orbit and cannot return to Earth. The first few Starship Moon landers may also be functionally expendable and only used for one astronaut landing apiece. In short, SpaceX already has extensive plans to build variants of Starship that are either fully expendable or can only be reused in orbit.

Single-use Starships
In early 2023, SpaceX updated the Starship section of its website, revealing that an expendable version of the rocket will be able to launch up to 250 metric tons (~550,000 lbs) to low Earth orbit in a single launch. Saturn V, the next most capable expendable rocket, could launch up to 118 tons (~260,000 lbs) to LEO and cost $1-2 billion per launch. SpaceX publicly advertising the expendable performance of Starship unsurprisingly confirms that the company is considering all of the capabilities its new launch system will offer.
And Starship’s expendable capabilities are significant. Constructed piece by piece over dozens of launches, the International Space Station weighs about 420 tons (~925,000 lbs). Two expendable Starships could launch more usable mass to LEO – truly revolutionary if SpaceX can make Starship launches frequent and routine.

Tesla Cybercab gets a for sale date at last
Update: 10/22 10:51a – Para 1 consumers changed to “customers” for accuracy.
Tesla Cybercab units finally got a definitive date for when they will be able to be purchased by customers, ending speculation regarding whether the fully autonomous vehicle would be available in the near term.
During Tesla’s third-quarter 2026 earnings call on October 21, Vice President of Engineering Lars Moravy said the company is aiming to begin delivering its purpose-built Cybercab robotaxi to customers before year-end.
🚨 In short, Cybercabs are slated to go to customers by end of the year. All units are going into Robotaxi fleet currently, per @larsmoravy
Cybercab will be “transport-as-a-service,” but vast majority of Cybercab will be “Tesla-owned,” @elonmusk says https://t.co/R8Qu8QWdmp
— TESLARATI (@Teslarati) October 21, 2026
“We’re trying to get Cybercabs to customers by the end of this year, 2026,” Moravy said. He added that production is underway on the line at Gigafactory Texas, but “all of those are currently going to our own internal Robotaxi fleet.”
Moravy explained that as operations scale, Tesla will “mainly deliver fully designed autonomous vehicles to our customers,” with the Cybercab as the first such vehicle. Initial customer deliveries will start small while the company gains experience with delivery logistics, ownership models, fleet management, and operating autonomous vehicles outside its direct control.
CEO Elon Musk reinforced the limited nature of private sales, describing the Cybercab primarily as a “transport-as-a-service” offering rather than a personal ownership vehicle like the Model 3, Model Y, or upcoming Roadster. “The vast majority of the Cybercab stuff will be Tesla-owned and transport-as-a-service,” Musk said.
The Cybercab is a two-seater vehicle developed by Tesla without a steering wheel or pedals. It relies completely on Tesla’s Full Self-Driving suite and has been in production since February. Early units have been put in Tesla’s Robotaxi service as of early September, when the company launched rides to the public. Tesla previously indicated it would aim to sell Cybercabs for about $30,000.
Unsupervised Full Self-Driving is expected to ship to consumer cars during Q2 2027, Ashok Elluswamy, Tesla’s Head of AI, indicated during the call. Early buyers or fleet operators may receive vehicles whose autonomous operation remains geographically restricted due to lagging regulatory agencies. There are some hurdles that remain ahead of Cybercab deliveries.

FCF: $1.531B— TESLARATI (@Teslarati) October 21, 2026
Major Takeaways
Full Self-Driving (Supervised)
“FSD (Supervised)⁴ attach rate continued to grow, reaching over 75% of new vehicle deliveries in North America – our most mature market – a nearly twenty percentage point sequential increase. We believe that FSD is driving demand in markets where it is available, and we continue to work with regulators to get it approved in other markets.”
Tesla Semi
“We began volume production of Tesla Semi, our Class 8 heavy-duty truck. The top variant can go 500 miles at full 82,000 lbs gross combination weight while achieving an efficiency of 1.7 kWh/mile. That efficiency allows the Tesla Semi to use a third of the energy used by a comparable diesel truck to haul the same payload. In a transportation market where energy is one of the largest components of total cost per mile, this will provide a meaningful advantage to Tesla Semi operators.”
SI Compute
“We plan to reach 400 MW of SI training compute by the end of the year, supporting the development of both vehicle and humanoid robot autonomy software. Additionally, we continued construction for the Austin Fab, where we plan to start commissioning equipment in 2027.”
Robotaxi
“We began deployment of Cybercab into our Robotaxi fleet in Austin. We reached nearly two million cumulative unsupervised miles for our Robotaxi service as of the end of the quarter. Operating hours in Austin are now 6am to midnight, and we expect to reduce wait times via increased fleet supply and improvement of Robotaxi orchestration algorithms. Grok is available in Cybercab with access to Grok Bot and Connectors, which allows users to manage their inbox, calendars, files, chats and tasks – all hands free via voice command – making Cybercab a mode of transport, a productivity space and, with our entertainment options, a second living room.”

Investor's Corner
Tesla reports Q3 Earnings today: here’s what to expect
Tesla (NASDAQ: TSLA) reports its earnings for Q3 today. Here’s what to expect, as the company will reveal its balance sheet after the market closes on Wednesday.
Tesla already reported deliveries just after Q3 ended, and it demolished Wall Street consensus estimates of roughly 462,000 vehicles. Tesla delivered 486,532 cars in the third quarter, which was a big beat, but was down 2.1 percent from the same quarter last year. Energy storage deployments were 13.7 GWh, up year-over-year.
Tesla showrooms picked clean ahead of Q3 end as demand looks strong
For the quarter, analysts have already compiled their predictions for what Tesla will report this afternoon:
- Total Revenues: $28.34B
- Non-GAAP EPS: $0.43
- Operating Margin: 2.5%
- Operating Income: $721M
- Free Cash Flow: ~-$4.51B
Here are a few things we are looking forward to hearing about on the call:
Automotive Gross Margin and Overall Profitability
This was 16.3 percent in Q2, down from 19.2 percent in Q1, and was impacted by warranty charges and some fading regulatory credits. Consensus implies overall gross margin near 18 percent, but a miss here would potentially reinforce concerns about pricing pressure on its vehicles.
Pay attention to energy storage margins as well, especially since Tesla missed GWh expectations, although it was still a strong quarter.
Robotaxi/Cybercab, Unsupervised FSD, and Optimus Progress
The Say questions from retail investors usually focus on these types of projects, and this quarter is no different. Scaling the Cybercab fleet beyond Austin amid the open NHTSA safety review, timeline for Unsupervised FSD in customer cars, Robotaxi unit economics, and Optimus cost per unit plus when it could start generating revenue, are all things to be looking for.
Any concrete timelines or regulatory path details will likely move the stock more than the near-term numbers. SpaceX merger speculation, which was detailed during SpaceX’s earnings call last night, may also surface, although the key details were shared last night.
Elon Musk just confirmed the Tesla and SpaceX merger step everyone was waiting for
Say Investor Questions
- How does the Cybercab fleet scale past Austin, and what’s the regulatory path outside Texas given NHTSA’s open safety review?
- When can we anticipate FSD unsupervised in customer cars?
- When will the CyberCab be available for customer purchase/ownership?
- What’s the unit economics per paid robotaxi mile, and how does it compare to the thirty-cent target?
- Tesla has acknowledged that HW3 vehicles cannot support unsupervised FSD. When will owners know whether they can upgrade their hardware for free, and when will Tesla provide a clear plan?
The full Earnings Call will be streamed this evening after market close around 5 p.m. this evening.
