Tesla’s Elon Musk pens open invite to TSLA short with surprise gift offering
Following a note to his investors alleging that Elon Musk continues to commit fraud, prominent TSLA short and hedge fund manager David Einhorn has received a response from the Tesla CEO. Musk’s letter, which he shared on Twitter, appears to be a snarky olive branch that offers Einhorn an opportunity to change his mind about the electric car maker.
Einhorn’s Greenlight Capital, which declined by 34% last year partly due to his bet against Tesla, lost its bet against the electric car maker once more in the third quarter. In a letter to his firm’s investors, Einhorn admitted that TSLA was one of its “material losers” of Q3’19 while accusing Elon Musk of “knowingly” orchestrating “significant fraud” with Tesla’s SolarCity buyout in 2016. The TSLA short also accused the electric car maker of failing to warn customers about its burning solar panels and its car battery fires.
Musk, who appears to be adopting a rather confident stance, shared a letter to the hedge fund manager on Twitter. Playfully calling Einhorn by the German translation of his name and dubbing himself as “Treelon Musk,” the Tesla CEO extended a rather snarky olive branch to the short seller. In his letter, Musk invited Einhorn to meet with him and see Tesla’s work firsthand, something that would be wise for the sake of Greenlight Capital’s investors.

Following is Musk’s letter in full.
Dear Mr. Unicorn (fabulous name btw),
We read your Greenlight Capital Q3’19 Investor Letter, in which you make numerous false allegations against Tesla. It is understandable that you wish to save face with your investors, given the losses you suffered from Tesla’s successful third quarter, especially since you’ve had several down years in performance and a sharp drop in assets under management from $15 billion to $5 billion. You have our sympathies.
We also recognize your desire to feel somehow relevant with your Tesla short position at a time when your friends in the Tesla short community have been noticeably recoiling from the public discourse, as the world is increasingly recognizing Tesla’s contributions to science, safety and a sustainable environment.
To the extent that you have any desire to learn about the amazing progress the people of Tesla are making, I would like to extend an open invitation to meet with me to discuss Tesla and tour our facilities. For their sake, I’m certain your investors would appreciate you getting smart on Tesla.
Finally, please allow us to send you a gift of short shorts to help you through this difficult time.
Regards,
Treelon Musk
Musk’s reference to Einhorn and a box of short shorts is based on a series of amusing events last year which began with Einhorn stating that he is not renewing the lease on his Tesla Model S due to tech issues with the car. Responding on Twitter, Musk stated that Tesla will “send Einhorn a box of short shorts to comfort him through this difficult time.” Following Elon Musk’s tweet, apparel maker Chubbies opted to send the hedge fund manager a literal box of shorts, most of which featured a very short 5.5-inch inseam.

Sure enough, Einhorn received his shorts, and he promptly took to Twitter to thank the Tesla CEO for being a “man of his word.” Musk responded by playfully asking Einhorn to put them on and post a selfie, but the TSLA short-seller did not comply. Perhaps this year, things will be different, or maybe Chubbies would be up for the task once more, considering that Kyle Hency, one of the company’s founders, stated that they could keep sending short shorts to TSLA shorts if Elon Musk wishes.

While Einhorn is a Tesla short and he continues to accuse Musk of fraud, among others, he appears to be a bit more level-headed compared to some of the angry, vapid TSLA retail and institutional short-sellers that populate Twitter. Perhaps this is one of the reasons why Musk actually opted to invite Einhorn in what seems to be an attempt to change the hedge fund manager’s mind. Elon Musk’s letter might be rife with snark, but it may, if Einhorn opts to respond, save his fund from more painful losses in the near future.
Investor's Corner
Tesla has a Cybercab problem nobody saw coming
Tesla’s Cybercab line now builds robotaxis faster than Tesla can deploy them, Lars Moravy says.
Tesla’s Cybercab line in Texas can now build the two seat robotaxi faster than the company can put it into service, according to Lars Moravy, Tesla’s Vice President of Vehicle Engineering. “We don’t run every day because the line can run so fast. It’s currently outpacing our deployments,” Moravy said in a new Cybercab deep dive from Munro Live. “So, it’s a bit of a race right now. Who’s going to go faster? Right now the manufacturing line’s ahead.”
Tesla’s official Robotaxi account shared a Cybercab analysis video on X on Monday, calling it a “Cybercab engineering deep dive.” Moravy’s comments go further than what he told analysts on the Q3 earnings call last week, when he said the Cybercab line’s listed capacity of more than 125,000 units a year undersells what it can actually run.
The tour shows where that speed comes from. Tesla’s unboxed process splits the Cybercab into front, rear, side and center modules that are built and tested on their own before they meet on a short final line. That final line has just 25 fully automated stations, which Tesla’s team estimated is a fifth to a tenth of what a Model Y needs. The full line is about 78% automated, the framing line is already at 100%, and the layout uses roughly 50% less floor space per vehicle. The stated goal is “100% automation in 10 second cycle time,” or one finished Cybercab every 10 seconds.
Tesla also deleted the paint shop. Only the side modules are coated, and the exterior panels get their color inside the molding machine. Engineers said the car is designed to run at least 500,000 miles, which matters for a vehicle that will spend most of its day carrying riders.
The battery got the same treatment. The Cybercab uses an 88S6P pack of 4680 cells in a steel enclosure, a first for Tesla, with each module potted separately so a single failed module can be swapped instead of the whole pack. Wireless battery management boards replace a wiring harness, and new contactors are fast enough to drop the pyro fuse entirely. Tesla’s battery director graded the pack an A minus, compared with a D for the Model Y structural pack and a B minus for Cybertruck. Up front, the drive unit runs an 11:1 gear ratio versus roughly 9:1 on most Teslas, since the Cybercab does not need a high top speed.
Cybercab engineering deep dive — Robotaxi (@robotaxi) October 26, 2026
The deployment side is now the bottleneck Moravy described. Tesla had more than 50 Cybercabs working the Formula 1 weekend in Austin, and Texas records show 463 Cybercabs registered. Tesla said on its earnings call that Cybercab service will launch in Dallas next month, and Moravy said the company is aiming to get Cybercabs to customers by the end of 2026. Every unit built so far has gone into Tesla’s own fleet since the line moved into volume production in April.
Munro Live also asked when it could get a Cybercab to tear down. Tesla’s answer: “Not yet.”
Tesla (NASDAQ: TSLA) reported its earnings for the third quarter of 2026, marking a reasonable performance on the various financial metrics. Tesla still plans to hold a call that will field investor questions at 5:30 p.m. ET, 4:30 p.m. CT.
Here’s where Earnings came in:
- Total Revenues: $28.046 reported vs. $28.34B expected
- Non-GAAP EPS: $0.48 reported vs. $0.45 expected
- Operating Margin: 2.6 % reported vs. 2.5% expected
- Operating Income: $718M reported vs. $721M expected
- Free Cash Flow: $1.531B reported vs. ~-$4.51B expected
Tesla $TSLA Earnings Results:
Revenues: $28.046B
Non-GAAP EPS: $0.48
Operating Margin: 2.6%
Operating Income: $718M
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.”

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.
