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.

Tesla analyst realizes one big thing about the stock: deliveries are losing importance
Tesla analyst Dan Levy of Barclays realized one big thing about the stock moving into 2026: vehicle deliveries are losing importance.
As a new era of Tesla seems to be on the horizon, the concern about vehicle deliveries and annual growth seems to be fading, at least according to many investors.
Even CEO Elon Musk has implied at times that the automotive side, as a whole, will only make up a small percentage of Tesla’s total valuation, as Optimus and AI begin to shine with importance.
He said in April:
“The future of the company is fundamentally based on large-scale autonomous cars and large-scale and large volume, vast numbers of autonomous humanoid robots.”
Almost all of Tesla’s value long-term will be from AI & robots, both vehicle & humanoid
— Elon Musk (@elonmusk) September 11, 2023
Levy wrote in a note to investors that Tesla’s Q4 delivery figures “likely won’t matter for the stock.” Barclays said in the note that it expects deliveries to be “soft” for the quarter.
In years past, Tesla analysts, investors, and fans were focused on automotive growth.
Cars were truly the biggest thing the stock had to offer: Tesla was a growing automotive company with a lot of prowess in AI and software, but deliveries held the most impact, along with vehicle pricing. These types of things had huge impacts on the stock years ago.
In fact, several large swings occurred because of Tesla either beating or missing delivery estimates:
- January 3, 2022: +13.53%, record deliveries at the time
- January 3, 2023: -12.24%, missed deliveries
- July 2, 2024: +10.20%, beat delivery expectations
- October 3, 2022: -8.61%, sharp miss due to Shanghai factory shutdown
- July 2, 2020: +7.95%, topped low COVID-era expectations with sizeable beat on deliveries
It has become more apparent over the past few quarters that delivery estimates have significantly less focus from investors, who are instead looking for progress in AI, Optimus, Cybercab, and other projects.
These things are the future of the company, and although Tesla will always sell cars, the stock is more impacted by the software the vehicle is running, and not necessarily the vehicle itself.

SpaceX IPO is coming, CEO Elon Musk confirms
However, it appears Musk is ready for SpaceX to go public, as Ars Technica Senior Space Editor Eric Berger wrote an op-ed that indicated he thought SpaceX would go public soon. Musk replied, basically confirming it.
Elon Musk confirmed through a post on X that a SpaceX initial public offering (IPO) is on the way after hinting at it several times earlier this year.
It also comes one day after Bloomberg reported that SpaceX was aiming for a valuation of $1.5 trillion, adding that it wanted to raise $30 billion.
Musk has been transparent for most of the year that he wanted to try to figure out a way to get Tesla shareholders to invest in SpaceX, giving them access to the stock.
He has also recognized the issues of having a public stock, like litigation exposure, quarterly reporting pressures, and other inconveniences.
However, it appears Musk is ready for SpaceX to go public, as Ars Technica Senior Space Editor Eric Berger wrote an op-ed that indicated he thought SpaceX would go public soon.
Musk replied, basically confirming it:
As usual, Eric is accurate
— Elon Musk (@elonmusk) December 10, 2025
Berger believes the IPO would help support the need for $30 billion or more in capital needed to fund AI integration projects, such as space-based data centers and lunar satellite factories. Musk confirmed recently that SpaceX “will be doing” data centers in orbit.
AI appears to be a “key part” of SpaceX getting to Musk, Berger also wrote. When writing about whether or not Optimus is a viable project and product for the company, he says that none of that matters. Musk thinks it is, and that’s all that matters.
It seems like Musk has certainly mulled something this big for a very long time, and the idea of taking SpaceX public is not just likely; it is necessary for the company to get to Mars.
The details of when SpaceX will finally hit that public status are not known. Many of the reports that came out over the past few days indicate it would happen in 2026, so sooner rather than later.
But there are a lot of things on Musk’s plate early next year, especially with Cybercab production, the potential launch of Unsupervised Full Self-Driving, and the Roadster unveiling, all planned for Q1.

Tesla Full Self-Driving statistic impresses Wall Street firm: ‘Very close to unsupervised’
The data shows there was a significant jump in miles traveled between interventions as Tesla transitioned drivers to v14.1 back in October. The FSD Community Tracker saw a jump from 441 miles to over 9,200 miles, the most significant improvement in four years.
Tesla Full Self-Driving performance and statistics continue to impress everyone, from retail investors to Wall Street firms. However, one analyst believes Tesla’s driving suite is “very close” to achieving unsupervised self-driving.
On Tuesday, Piper Sandler analyst Alexander Potter said that Tesla’s recent launch of Full Self-Driving version 14 increased the number of miles traveled between interventions by a drastic margin, based on data compiled by a Full Self-Driving Community Tracker.

The data shows there was a significant jump in miles traveled between interventions as Tesla transitioned drivers to v14.1 back in October. The FSD Community Tracker saw a jump from 441 miles to over 9,200 miles, the most significant improvement in four years.
Interestingly, there was a slight dip in the miles traveled between interventions with the release of v14.2. Piper Sandler said investor interest in FSD has increased.
Full Self-Driving has displayed several improvements with v14, including the introduction of Arrival Options that allow specific parking situations to be chosen by the driver prior to arriving at the destination. Owners can choose from Street Parking, Parking Garages, Parking Lots, Chargers, and Driveways.
Additionally, the overall improvements in performance from v13 have been evident through smoother operation, fewer mistakes during routine operation, and a more refined decision-making process.
Early versions of v14 exhibited stuttering and brake stabbing, but Tesla did a great job of confronting the issue and eliminating it altogether with the release of v14.2.
Tesla CEO Elon Musk also recently stated that the current v14.2 FSD suite is also less restrictive with drivers looking at their phones, which has caused some controversy within the community.
Although we tested it and found there were fewer nudges by the driver monitoring system to push eyes back to the road, we still would not recommend it due to laws and regulations.

With that being said, FSD is improving significantly with each larger rollout, and Musk believes the final piece of the puzzle will be unveiled with FSD v14.3, which could come later this year or early in 2026.
Piper Sandler reaffirmed its $500 price target on Tesla shares, as well as its ‘Overweight’ rating.
